## 95 Building Complex **

Problem: A building cannot truly serve human needs unless it comprises smaller buildings or components that reflect its internal social organization.

Solution: Avoid constructing large monolithic structures. When possible, translate your building program into a complex of elements that express the actual social relationships of the situation. In lower-density areas, this may manifest as clusters of small buildings linked by arcades, paths, bridges, shared gardens, and walls.

In higher-density settings, a single building can function as a complex if its key components are clearly defined while remaining part of a unified three-dimensional composition.

Even smaller structures like houses can be conceptualized as "building complexes"—perhaps featuring elevated sections with wings and adjoining cottages.

## 96 Number of Stories *

Problem: Within the established four-story height limit, what is the optimal height for your specific buildings?

Solution: Begin by calculating your required square footage of built space, then divide by the site area to determine the floor area ratio. Select your building height based on this ratio and the heights of surrounding structures, using the provided reference table. Under no circumstances should you build on more than 50 percent of the available land.

## 97 Shielded Parking *

Problem: Large parking structures filled with cars create inhospitable, lifeless environments that pedestrians avoid. Yet for drivers, parking entrances effectively serve as main entrances to buildings and need to remain visible.

Solution: Conceal substantial parking lots or garages behind natural barriers to shield vehicles and parking structures from external view. These screening elements might include buildings, connected houses, housing hills, earth berms, or shops.

Design the parking entrance as a natural gateway to the buildings it serves, positioned so that the main building entrance is clearly visible from the parking entrance point.

## 98 Circulation Realms **

Problem: Disorientation is a significant issue in many contemporary building complexes. People frequently lose their bearings, causing considerable mental distress.

Solution: Configure large buildings and building clusters so that reaching any interior destination requires passing through a sequence of distinct realms. Each realm should be marked by a gateway, with spaces becoming progressively smaller as one moves deeper into the sequence. Select realms that can be easily named, enabling clear directional instructions by simply identifying which realms to traverse.

## 99 Main Building *

Problem: A building complex without a focal point resembles a body without a head—it lacks essential organization and identity.

Solution: For any building group, identify which structure houses the most essential function—the building that represents the soul of the group as a human institution. Develop this as the main building, giving it a central position and higher roof to establish its prominence.

Even in dense complexes that form a single building, make the primary section taller and more visually prominent than surrounding elements, ensuring that attention naturally gravitates toward the most important part.

## 101 Building Thoroughfare

Problem: Public building complexes that cannot be fully serviced by outdoor pedestrian walkways require an alternative to conventional corridors for indoor circulation.

Solution: In situations where climate or density necessitates moving primary circulation routes indoors, construct them as building thoroughfares. Position each thoroughfare to function as a convenient shortcut, maintaining continuity with the external public streets and featuring wide, accessible entrances. Along the edges, incorporate windows, seating areas, counters, and entrances that extend into the hall, making the building's primary functions visible to passersby. Design these thoroughfares wider than standard corridors—minimum 11 feet, but preferably 15-20 feet wide— with high ceilings (at least 15 feet), potentially including glazed roofing and lower-height areas along the perimeter. In multi-story thoroughfares, walkways on different levels can be utilized to create these lower-height spaces along the edges.

## 103 Small Parking Lots *

Problem: Large-scale parking facilities significantly degrade the human experience of the landscape.

Solution: Develop compact parking areas accommodating only 5-7 vehicles each, enclosed by garden walls, hedges, fences, embankments, and trees to render the vehicles nearly invisible from outside. Distribute these small lots with a minimum of 100 feet between them.

## 105 South Facing Outdoors **

Problem: In all but desert environments, people gravitate toward sunlit outdoor spaces and avoid shaded areas.

Solution: Position buildings on the northern side of their associated outdoor spaces, keeping the outdoor areas to the south. Avoid creating deep bands of shade between buildings and the sunny portions of exterior spaces.

## 106 Positive Outdoor Space **

Problem: Outdoor areas that are merely leftover spaces between buildings typically remain unused.

Solution: Design all outdoor spaces surrounding and between buildings to have positive, intentional qualities. Provide each space with some degree of enclosure by using building wings, trees, hedges, fences, arcades, and trellised walkways to define its boundaries. This creates distinct entities with clear spatial definition rather than amorphous areas that dissipate around corners.

## 107 Wings of Light **

Problem: Contemporary architecture often ignores natural illumination, relying predominantly on artificial lighting. However, buildings that minimize natural light as the primary illumination source create environments unsuitable for extended human occupation.

Solution: Structure each building to divide into wings that roughly correspond to the most significant natural social groupings within the building. Design each wing to be elongated and as narrow as feasible—never exceeding 25 feet in width.

## 108 Connected Buildings *

Problem: Buildings that stand in isolation reflect the fragmentation of an unhealthy society.

Solution: Whenever possible, integrate your building with existing structures in the surrounding area. Avoid maintaining setbacks between buildings; instead, strive to design new structures as extensions of established ones.

## 110 Main Entrance **

Problem: The location of a building's main entrance(s) represents perhaps the most crucial decision in the development of its floor plan.

Solution: Situate the building's main entrance where it can be readily observed from primary approach routes, and give it a distinctive, prominent form that projects outward from the building façade.

## 112 Entrance Transition **

Problem: Structures, particularly residential ones, that incorporate a thoughtful transition between street and interior create a more serene atmosphere than those with direct street access.

Solution: Create an intermediate space between the street and front door. Guide the connecting pathway through this transitional area, marking it with various sensory shifts—changes in lighting, acoustics, direction, surface texture, elevation, enclosure (possibly using gateways), and most importantly, a change in visual perspective.

## 114 Hierarchy of Open Space *

Problem: When outside, individuals instinctively seek positions where their backs are protected while facing toward a more expansive area beyond their immediate surroundings.

Solution: In designing any outdoor space—garden, terrace, street, park, public gathering area, or courtyard—ensure two key elements. First, create at least one smaller space that overlooks it and serves as a natural backdrop. Second, position the space and its openings to provide views of at least one larger, more distant area. This arrangement gives every outdoor space a natural "back," allowing anyone who positions themselves against this backdrop to face outward toward a more expansive vista.

## 115 Courtyards Which Live **

Problem: Contemporary building courtyards often remain unused and lifeless. Though intended to function as private open spaces for people's enjoyment, they frequently end up abandoned, filled with gravel and abstract art installations rather than human activity.

Solution: Position each courtyard to provide a view of a larger open area beyond. Ensure that at least two or three doorways open from the building directly into the courtyard, with natural pathways between these doors crossing through the courtyard space. Along one edge, adjacent to a doorway, construct a roofed veranda or porch that seamlessly connects both the interior and the courtyard.

## 116 Cascade of Roofs *

Problem: Buildings rarely maintain structural and social integrity unless the floors descend toward the ends of wings and the roof correspondingly forms a cascading pattern.

Solution: Conceptualize the entire building or complex as a system of interconnected roofs. Position the largest, tallest, and widest roofs above the most significant portions of the building. When detailing the roof layout, arrange smaller roofs to cascade from these larger ones, creating a stable, self-supporting system that aligns with the hierarchy of social spaces beneath.

## 117 Sheltering Roof **

Problem: The roof fulfills a fundamental role in our existence. The most basic structures are essentially just roofs. When a roof is concealed, when its presence cannot be sensed throughout the building, or when it serves no practical purpose, people lose an essential sense of protection and shelter.

Solution: Create sloped roofs or vaulted ceilings with fully visible surfaces. Extend the eaves down low, particularly near entrances and pausing points, bringing them as low as 6'0" or 6'6". Integrate the top floor of each wing directly into the roof structure so that the roof doesn't merely cover the space but entirely envelops it.

## 119 Arcades **

Problem: Arcades—covered walkways at building edges that exist partially indoors and partially outdoors—serve a crucial function in facilitating human interactions with buildings.

Solution: Construct arcades wherever paths run alongside buildings. Utilize these arcades primarily to connect buildings to one another, enabling pedestrians to move from place to place under the protection of these covered passages.

## 120 Paths and Goals *

Problem: Path design will only feel appropriate and comfortable when it harmonizes with the act of walking—a process far more nuanced than most people realize.

Solution: Begin path layout by identifying goals at natural points of interest. Then connect these goals to form pathways. The paths may be either straight or gently curved between goals, with paving that expands around each goal point. Keep goals at moderate distances, never more than a few hundred feet apart from one another.

## 121 Path Shape *

Problem: Modern streets primarily serve as thoroughfares rather than places where people can linger and gather, contrary to their potential social function.

Solution: Design public paths with a widened central area and narrower endpoints, creating an enclosed space that invites people to stay rather than merely pass through.

## 122 Building Fronts *

Problem: Building set-backs, originally implemented to ensure public welfare through adequate light and air for all structures, have ironically contributed significantly to the decline of streets as vibrant social environments.

Solution: Never permit set-backs between streets, paths, or public land and the buildings that face them. These set-backs provide no valuable function and typically diminish the quality of open areas between buildings. Construct buildings directly adjacent to pathways; work to change regulations in communities where outdated building codes prevent this approach. Allow building frontages to adopt slightly irregular angles as they adapt to street contours.

## 124 Activity Pockets **

Problem: The vitality of a public square naturally develops around its perimeter. If this edge fails to function properly, the space never becomes animated with human activity.

Solution: Encircle public gathering spaces with activity pockets—small, partially enclosed areas at the edges that extend into the open space between paths. These pockets should contain functions that naturally encourage people to pause and engage with the environment.

## 125 Stair Seats *

Problem: In active spaces, the most appealing spots are those elevated enough to provide perspective but low enough to keep people engaged with the activity.

Solution: In public spaces where people tend to linger, incorporate a few steps at edges where staircases descend or where level changes occur. Make these elevated areas easily accessible from below, creating spaces where people can gather and sit to observe ongoing activities.

## 128 Indoor Sunlight *

Problem: When appropriate rooms have southern exposure, homes feel bright, cheerful and welcoming; when inappropriate rooms face south, homes can feel dark and dreary.

Solution: Position the most significant rooms along the southern edge of the building, and extend the structure along the east-west axis.

Adjust the layout to ensure appropriate rooms receive southeastern and southwestern sunlight. For instance: give common spaces full southern exposure, place bedrooms to the southeast, and position the porch to the southwest. For most climate zones, this requires a building shape that is elongated on the east-west axis.

## 129 Common Areas at the Heart **

Problem: Social groups - whether families, work teams, or school communities - cannot thrive without regular informal interactions among members.

Solution: Establish a single shared space for each social group. Position it at the center of gravity of all spaces the group uses, and arrange it so that paths entering and exiting the building run tangentially to this central area.

## 130 Entrance Room **

Problem: When entering or exiting a building, people need a transitional space that serves as a passage both inside and outside the structure. This space functions as the entrance room.

Solution: Create a light-filled room at the main entrance that bridges indoor and outdoor spaces, encompassing area both outside and inside the building. The exterior portion might resemble a traditional porch, while the interior could function as a hall or sitting area.

## 131 The Flow Through Rooms

Problem: Movement between rooms is equally important as the rooms themselves, and how this movement is arranged significantly impacts social interaction within those rooms.

Solution: Minimize corridors and passages whenever possible. Instead, utilize public and common rooms as spaces for both movement and gathering. Arrange common rooms in a chain or loop pattern, enabling movement from room to room, with private rooms opening directly into these public spaces. In all cases, create generous indoor circulation paths that form wide, ample loops throughout the house, featuring views of fireplaces and large windows.

## 133 Staircase as a Stage

Problem: A staircase serves more than just connecting different floors. It constitutes its own space, volume, and integral part of the building; if this space isn't enlivened, it becomes a dead zone that fragments the building and disrupts its functional processes.

Solution: Situate the main staircase in a prominent, central, and visible location. Design the entire staircase as a room (or as a courtyard if it's exterior). Integrate the stair with the room so they function as one unit, with the staircase descending around one or two walls of the room. Design the bottom of the stair to widen out with open windows or balustrades and broad steps, allowing people descending to participate in the room's activities while on the stairs, and encouraging those below to use the stairs as seating.

## 159 Light on Two Sides of Every Room **

Problem: Given options, individuals consistently prefer rooms illuminated from multiple sides, leaving spaces lit from just one direction largely unused and vacant.

Solution: Position each room so it has exterior space on at least two sides, then install windows in these exterior walls to allow daylight to enter every room from multiple directions.

## 160 Building Edge **

Problem: Buildings are typically conceived as inward-focused structures centered around their internal spaces. The outward orientation of buildings is frequently overlooked in design considerations.

Solution: Consider the building's edge as a substantive element with volume rather than a mere line or interface without depth. Create indentations along the building perimeter with areas that encourage people to pause. Develop spaces with depth and coverage - places to sit, lean, and stroll - especially at points along the perimeter that overlook engaging outdoor activities.

## 161 Sunny Place **

Problem: The southern-facing area immediately outside a building - that intersection between walls and ground where sunlight falls - needs deliberate development to create a space where people can enjoy the sunshine.

Solution: Within a south-facing courtyard, garden, or yard, identify the location between the building and exterior that receives optimal sunlight. Develop this spot into a special sunny retreat - make it the primary outdoor space, suitable for working in the sun, installing a swing and special plantings, or sunbathing. Take particular care to position the sunny area where it's protected from wind. Even consistent mild breezes will prevent enjoyment of the most appealing location.

## 163 Outdoor Room **

Problem: Traditional gardens provide space for activities like lying in grass, swinging, playing croquet, growing flowers, or playing fetch with a dog. However, there's another way to experience the outdoors that gardens don't adequately address.

Solution: Create an outdoor space with sufficient enclosure that it feels like a room despite being open to the sky. Define its corners with columns, consider partial roofing with a trellis or adjustable canvas, and establish "walls" using elements such as fences, sitting walls, screens, hedges, or the building's exterior walls.

## 166 Gallery Surround *

Problem: When occupants cannot exit a building onto balconies and terraces that overlook the surrounding outdoor space, neither they nor people outside have any medium helping them feel that the building and the broader public world are interconnected.

Solution: At every level of the building where possible, construct elements such as porches, galleries, arcades, balconies, niches, outdoor seats, awnings, and trellised rooms along the building edges—particularly where they open to public spaces and streets—and connect them directly to interior rooms via doorways.

## 167 Six-Foot Balcony **

Problem: Balconies and porches that are less than six feet in depth rarely get used.

Solution: When constructing a balcony, porch, gallery, or terrace, always ensure it's at least six feet deep. If feasible, recess at least a portion of it into the building rather than having it completely cantilevered out and separated from the building by a simple line, and include partial enclosure.

## 168 Connection to the Earth **

Problem: A house can feel disconnected from the surrounding natural environment unless its floors directly integrate with the earth around the structure.

Solution: Link the building to its surrounding earth by creating a network of paths, terraces, and steps around its perimeter. Place these elements deliberately to create ambiguous boundaries— making it difficult to determine precisely where the building ends and the earth begins.

## 171 Tree Places **

Problem: When trees are planted or trimmed without consideration for the unique spaces they can create, they become essentially useless to the people who need them.

Solution: When planting trees, arrange them according to their natural characteristics to form enclosures, avenues, squares, groves, and individual spreading specimens toward the center of open areas. Shape nearby buildings in response to the trees, ensuring that both the trees individually and the trees and buildings together create functional spaces for people.

## 174 Trellised Walk **

Problem: Trellised walkways possess a distinctive beauty. They're so unique and different from other path designs that they're almost archetypal in nature.

Solution: For paths requiring special protection or intimacy, construct a trellis over the walkway and plant climbing flowers on it. Use the trellis to help define and shape the outdoor spaces on both sides of the path.

## 191 The Shape of Indoor Space **

Problem: The flawless geometric squares and rectangles characteristic of ultra-modern architecture lack meaningful connection to human needs or structural logic. They merely represent rigid ideals and fantasies that emerge when people become overly focused on systems and production methods.

Solution: With some exceptions, design each indoor space or section of a space as an approximate rectangle, featuring relatively straight walls, near-right-angle corners, and a generally symmetrical vault covering each room.

## 195 Staircase Volume *

Problem: This pattern is included because our research has shown that non-professionals frequently miscalculate the volume required for staircases, resulting in plans that cannot be implemented.

Solution: Create a two-story volume to house the staircase, whether it's straight, L-shaped, U- shaped, or C-shaped. The stairs may range from 2 feet wide (for very steep stairs) to 5 feet wide (for generous, gradual stairs). In all cases, the entire stairwell must constitute one complete structural bay with two-story height. Don't assume all stairs must conform to the "standard" 30-degree angle. The steepest stairs might almost resemble ladders, while the most generous can be as gradual as ramps and quite wide. When determining the exact slope of your stairs, remember the relationship: riser + tread = 17½ inches.

## 202 Built-In Seats *

Problem: Built-in seating offers comfort and luxury to buildings, but frequently fails in practice. Common issues include improper placement, insufficient width, incorrect back angle, poor viewing position, or uncomfortable hardness. This pattern provides guidance for creating truly functional built-in seats.

Solution: Test the location before construction by placing an existing armchair or sofa in your intended position. Adjust it until you find an optimal spot. Leave it there for several days to verify you genuinely enjoy sitting there. If you find yourself naturally gravitating to sit in it, you've found the right location. Then construct your built-in seat with identical width and cushioning to ensure its success.

## 205 Structure Follows Social Spaces **

Problem: Buildings feel uncomfortable to occupants when the physical architecture (defined by columns, walls, and ceilings) doesn't align with the social spaces (defined by activities and human interactions).

Solution: Establish this fundamental construction principle: never allow engineering requirements to dictate the building's form. Instead, position all load-bearing elements - columns, walls, and floors - to complement the social spaces within the building. The engineering structure should adapt to support human activities, rather than forcing social spaces to conform to structural necessities.

## 206 Efficient Structure *

Problem: Buildings employ various structural systems: column and beam, load-bearing walls with slab floors, vaults, domes, or tents. But which approach or combination is truly most efficient? What's the optimal way to distribute building materials to create strong, well-enclosed spaces while minimizing material usage?

Solution: Design the building as a unified body of compressive material. Geometrically, envision it as a three-dimensional system of individually vaulted spaces, predominantly rectangular. Use thin load-bearing walls stiffened with intermittent columns. Reinforce wall junctions, connections between walls and vaults, and areas surrounding openings with additional thickness.

## 207 Good Materials **

Problem: Modern industrial society presents a fundamental conflict regarding building materials.

Solution: Select only biodegradable materials with low energy requirements that can be easily modified on-site. For primary structural elements, consider ultra-lightweight concrete (40-60 lbs) and earth-based materials such as tamped earth, brick, and tile. For secondary components, utilize wood planks, gypsum, plywood, cloth, chickenwire, paper, cardboard, particle board, corrugated iron, lime plasters, bamboo, rope, and tile.

## 208 Gradual Stiffening **

Problem: Pattern languages are fundamentally about creating buildings uniquely adapted to individual needs and sites. This philosophy requires building plans that remain loose and fluid to accommodate subtle adaptations.

Solution: Understand that construction isn't like assembling an erector set from discrete components. Instead, think of it as weaving a structure that begins globally complete but flexible, then progressively increases in stiffness while maintaining some flexibility, before finally achieving complete rigidity and strength. In contemporary building, this approach naturally translates to erecting a shell of sheet materials, then strengthening it by adding compressive fill.

## 209 Roof Layout *

Problem: What roof design will organically integrate with your building's nature?

Solution: Design your roof plan so each distinct roof section corresponds to an identifiable social unit within the building or complex. Position the largest and highest-spanning roofs over the most important communal spaces. Extend lesser roofs from these primary roof structures, and create the smallest roofs as half-vaults and sheds covering alcoves and thick walls.

## 221 Natural Doors and Windows **

Problem: Determining the ideal placement for windows and doors requires nuanced consideration, yet few construction methods acknowledge this subtlety.

Solution: Never use standardized doors or windows. Create windows of varying sizes based on their specific location. Don't determine the exact size or position of door and window frames until the room's rough framing is complete. Stand physically within the space and use your visual judgment to decide optimal placement and dimensions. Mark your chosen openings with string. As you progress higher in the building, make the windows progressively smaller.

## 225 Frames as Thickened Edges **

Problem: A membrane with openings is vulnerable to tearing at those openings unless the edges are strengthened with additional material.

Solution: Rather than treating door and window frames as independent rigid structures inserted into wall openings, conceive of them as integral thickenings of the wall itself, designed to distribute the stress that concentrates around openings.

Following this concept, construct frames as extensions of the wall material, seamlessly integrated with the wall, using identical materials, and implemented in a way that maintains continuity with the wall's structure.

## 226 Column Place *

Problem: Columns that are too slender or designed solely based on structural considerations will never create a comfortable environment.

Solution: For freestanding columns, ensure they are at least as thick as a human body – minimum 12 inches, preferably 16 inches. Create spaces around them where people can comfortably sit or lean, such as a step, a small seat built against the column, or an area formed between paired columns.

## 239 Small Panes **

Problem: With the invention of plate glass windows, it was assumed they would connect us more closely with nature. However, the effect has been quite the opposite.

Solution: Break each window into multiple small panes. These should rarely exceed one foot square and can be much smaller. Determine appropriate pane dimensions by dividing the window's width and height by the desired number of panes. This approach creates uniquely proportioned panes for each window based on its specific dimensions.

## 240 Half-Inch Trim **

Problem: Buildings designed with machine-like precision don't require trim because of their exactness. However, this precision comes at a significant cost: it eliminates freedom and flexibility in building design.

Solution: At every junction between different materials, install a piece of trim that covers the connection. Select trim pieces so that the narrowest section in each component is approximately 1/2 inch wide. Materials for trim can include wood, plaster, terracotta, and other similar options.

## 241 Seat Spots **

Problem: Outdoor seating placed without consideration for views and climate conditions typically goes unused.

Solution: The location of outdoor seats matters far more than their design. When the spot is well- chosen, even the simplest bench works perfectly.

For cooler climates, position seats to capture sunlight and shield from wind; in warmer areas, place them in shaded locations with access to summer breezes. In all situations, orient seats to provide views of ongoing activities.

## 243 Sitting Wall **

Problem: Walls and fences between outdoor areas are often too tall, yet having no boundary at all fails to acknowledge the nuanced distinctions between different spaces.

Solution: Enclose natural outdoor spaces and create subtle boundaries between outdoor areas using low walls approximately 16 inches high. Make these walls wide enough to serve as seating—at least 12 inches across.

## 247 Paving with Cracks Between the Stones **

Problem: While asphalt and concrete outdoor surfaces are easily maintained, they provide no benefits for pathways, rainwater management, or plant life.

Solution: For paths and terraces, arrange paving stones with approximately 1-inch gaps between them to allow grass, moss, and small flowering plants to grow in these spaces. Place the stones directly on soil rather than mortar, and avoid using cement or mortar between the stones.

## 249 Ornament **

Problem: Humans naturally desire to embellish their surroundings.

Solution: Examine the building to identify edges and transitions that would benefit from emphasis or additional binding energy. Corners, material junctions, door frames, windows, entrances, wall intersections, garden gates, and fences all naturally invite ornamentation.

Develop simple themes and apply elements of these themes repeatedly to the edges and boundaries you've selected for emphasis. Design ornaments to function as seams along these boundaries, connecting the two sides and unifying them.

## 250 Warm Colors **

Problem: The greenish and grayish tones common in hospitals and office hallways create a cold, depressing atmosphere. Natural wood, sunlight, and vibrant colors provide warmth. The color temperature in a room significantly affects comfort levels.

Solution: Select surface colors that work with natural light, reflected light, and artificial lighting to generate a warm atmosphere throughout the rooms.
