Section 1: Architectural Design Philosophies
1.1 Rationalism — Structure as Expression
Rationalism holds that architectural form should derive from logical structural and programmatic reasoning. The building's truth lies in its clarity of organization and the honest expression of its constructive logic.
Core Tenets:
Form follows structural logic and material behavior
Spatial order derives from geometric and mathematical systems
Ornament is secondary to tectonic clarity
Repetition and modular coordination create visual coherence
Key Figures: Auguste Perret, Pier Luigi Nervi, Louis Kahn, Aldo Rossi, Giorgio Grassi

Kimbell Art Museum (Kahn, 1972) — cycloid vault shells spanning 30.5 m (100 ft), natural light slits at vault crowns
Palazzetto dello Sport, Rome (Nervi, 1957) — 58.5 m diameter ribbed dome, 1,620 precast concrete V-elements
Gallaratese Housing, Milan (Rossi, 1974) — archetypal column-and-lintel repetition, 182 m long block
Design Application: Begin with the structural bay as the generative unit. Derive spatial hierarchy from column grid spacing (typically 6.0 m, 7.5 m, 9.0 m, or 10.8 m grids in reinforced concrete). Express the load path visually. Eliminate non-structural partitions where possible to reveal the primary order.
1.2 Empiricism — Experience-Driven Design
Empiricism prioritizes direct human experience, sensory engagement, and contextual observation over abstract theory. Design decisions arise from studying how people actually inhabit and move through space.
Core Tenets:
User observation and post-occupancy data drive design
Spatial sequences are composed for experiential richness
Material selections respond to tactile and visual perception
Context (climate, culture, daily rituals) shapes form
Key Figures: Alvar Aalto, Ralph Erskine, Jorn Utzon, Herman Hertzberger, Giancarlo De Carlo
Canonical Works:
Paimio Sanatorium (Aalto, 1933) — patient rooms oriented for morning light, handrail profiles designed for tubercular grip
Byker Wall, Newcastle (Erskine, 1974) — 1.6 km perimeter wall shields against north wind, south-facing terraces capture sun
Centraal Beheer, Apeldoorn (Hertzberger, 1972) — 9 m x 9 m tartan grid of habitable blocks, 1,000 employees given agency over individual workspace configuration
Design Application: Conduct behavioral mapping during programming. Walk the site at dawn, midday, and dusk. Photograph existing pedestrian desire lines. Record ambient sound levels (target < 35 dB in work areas, < 45 dB in circulation). Document prevailing wind direction and velocity. Let these observations generate the parti rather than imposing a geometric diagram.
1.3 Phenomenology — Atmosphere, Body, Perception
Phenomenological architecture foregrounds the lived experience of space — the qualities of light, material, temperature, sound, and movement that constitute atmosphere. Architecture is understood through the sensing body rather than the detached eye.
Core Tenets:
Architecture is experienced multi-sensorially, not just visually
Atmosphere is a legitimate design objective (Zumthor's "architectural atmosphere")
Materials are valued for their tactile and temporal qualities (patina, weathering, warmth)
Thresholds, transitions, and spatial compression-expansion sequences shape experience
The body in motion is the measure of space
Key Figures: Martin Heidegger (philosophical ground), Christian Norberg-Schulz, Juhani Pallasmaa, Peter Zumthor, Steven Holl, Alberto Campo Baeza
Canonical Works:
Therme Vals (Zumthor, 1996) — local Vals gneiss quartzite in 31 mm, 47 mm, and 63 mm courses; water temperature progression from 14 C to 42 C; sound of water as spatial marker
Chapel of St. Ignatius, Seattle (Holl, 1997) — seven "bottles of light" in different colors for liturgical program; beeswax-finished walls
Bruder Klaus Field Chapel, Mechernich (Zumthor, 2007) — 12 m tall truncated cone, 112 tree trunks burned out to form interior surface, oculus open to rain and sky
Design Application: Compose spatial sequences as atmospheric scores. Map the visitor's journey through compression (2.4 m ceiling) to expansion (6.0 m+). Specify materials by touch: rough-sawn timber vs. honed stone vs. brushed steel. Design light as a material — calculate the sun's path and place apertures to create specific light conditions at specific times. Target a minimum of 3 sensory engagements per major space (visual, tactile, acoustic).
1.4 Pragmatism — Performance-Driven Design
Pragmatism evaluates architecture by how well it works: functionally, economically, environmentally, and socially. Performance metrics replace aesthetic judgment as the primary design criterion.
Centre Pompidou, Paris (Piano + Rogers, 1977) — all services externalized to free 7,500 m2 column-free floors, 48 m clear spans
30 St Mary Axe "Gherkin," London (Foster, 2004) — diagrid structure reduces steel by 21% vs. conventional frame, natural ventilation for 40% of occupied hours
VIA 57 West, New York (BIG, 2016) — courtyard-tower hybrid maximizes air and light while achieving 76,180 m2 (820,000 ft2) residential GFA on a constrained site
Design Application: Establish quantitative performance targets before sketching: target EUI, daylight factor (minimum 2% in occupied spaces), ventilation rates (ASHRAE 62.1: 8.5 L/s per person for offices), structural efficiency (kg steel/m2), and cost/m2. Use energy modeling (EnergyPlus, IES VE) from concept stage. Evaluate every design move against these metrics.
1.5 Critical Regionalism — Frampton's Six Points
Kenneth Frampton's 1983 essay "Towards a Critical Regionalism" argues for an architecture that resists both the placelessness of universal modernism and the sentimentality of historicism.
Frampton's Six Points:
Culture vs. Nature: Architecture mediates between the universalizing tendency of civilization and the particularities of local culture
The Rise and Fall of the Avant-Garde: Resist rear-guard historicism and avant-garde abstraction equally
Critical Regionalism and World Culture: Adopt universal technique but inflect it with local conditions
The Resistance of the Place-Form: Ground architecture in topography rather than impose upon it (build the site, not on the site)
Culture vs. Nature (Reprise): Modulate climate through architectural means — loggias, brise-soleil, cross-ventilation — rather than hermetic mechanical systems
The Visual vs. the Tactile: Foreground the tactile (materiality, light, temperature) over the purely visual (the photograph)
Marika-Alderton House, Northern Territory (Murcutt, 1994) — operable wall panels for cross-ventilation in tropical climate, raised on steel piers to allow air flow beneath
Indian Institute of Management, Ahmedabad (Doshi, 1977/2012 campus) — brick construction responding to Gujarat climate, deep overhangs, stepped terraces, water courts
Design Application: Map the site's genius loci: prevailing winds, solar geometry, topographic contours, local building materials within 500 km radius, vernacular construction techniques, and cultural use patterns. Develop the building section as a climate-responsive device before the plan. Use local materials for primary enclosure (target > 60% by weight from regional sources within 800 km per LEED MRc5).
1.6 Parametricism — Schumacher's Tenets
Patrik Schumacher's 2008 manifesto declares Parametricism the new epochal style after Modernism, arguing that digital tools enable continuously differentiated, relationally complex architectural and urban fields.
Core Tenets (Schumacher's Taboos and Dogmas):
Negative heuristics (taboos): Avoid rigid geometric primitives (boxes, cylinders), avoid simple repetition, avoid collage of unrelated elements
Positive heuristics (dogmas): All forms must be soft (nurbs-based), all systems must be interdependent (structure/envelope/program parametrically linked), differentiation must be gradual and lawful (no abrupt transitions)
Design Application: Define design parameters (site boundary, program areas, solar access, views, structural span) as variable inputs to a computational model (Grasshopper/Dynamo). Establish relationships between parameters (e.g., facade density varies with solar gain — 40% open on north, 15% on west). Generate multiple options through parameter variation. Evaluate with quantitative fitness criteria. The designer's role shifts from form-maker to system-designer.
1.7 Ecological Design — Regenerative and Biomimicry
Ecological design moves beyond sustainability (doing less harm) to regenerative design (creating net positive environmental impact). Biomimicry applies nature's 3.8 billion years of evolutionary strategies to architectural problems.
Core Tenets:
Buildings as ecosystems: produce energy, clean water, sequester carbon, support biodiversity
Cradle-to-Cradle material philosophy: all materials are either biological nutrients (compostable) or technical nutrients (infinitely recyclable)
Living Building Challenge 4.0: seven performance areas (place, water, energy, health, materials, equity, beauty) — the most stringent green building standard
Eastgate Centre, Harare (Pearce, 1996) — termite-mound-inspired passive ventilation, 90% less energy than conventional AC in sub-Saharan climate
Bosco Verticale, Milan (Boeri, 2014) — 900 trees, 5,000 shrubs, 11,000 perennial plants on two towers (110 m and 76 m), equivalent to 20,000 m2 of forest
Design Application: Set regenerative targets: net-positive energy (produce 105% of consumption), net-positive water (harvest > consumption + 10% for habitat), carbon sequestration (use mass timber, hempcrete, or biochar concrete to store > embodied carbon within 30 years). Use the Biomimicry Design Spiral at concept stage: what function does this building need to perform? How does nature achieve this function? Abstract the principle and apply it.
1.8 Social Architecture — Participation, Equity, Community Agency
Social architecture foregrounds the political and social dimensions of design: who designs, who is designed for, who benefits, and who is displaced.
Core Tenets:
Participatory design processes (not just consultation but genuine co-design)
Design justice: center the voices of those most impacted by design decisions
Incremental development: design frameworks that communities can build out over time
Commons and shared spaces as priorities over private enclosure
Anti-displacement strategies: community land trusts, inclusive zoning, affordable unit integration
Key Figures: Giancarlo De Carlo, Hassan Fathy, Alejandro Aravena, Yasmeen Lari, Francis Kere, Anna Heringer, Teddy Cruz
Canonical Works:
Quinta Monroy, Iquique (Aravena/ELEMENTAL, 2004) — half-houses at $7,500 each, 93 families, incremental design allowing residents to expand from 36 m2 to 72 m2
Gando Primary School, Burkina Faso (Kere, 2001) — community-built with local laterite clay, raised corrugated metal roof for stack-effect ventilation, $50,000 budget
METI School, Rudrapur (Heringer, 2006) — bamboo and earth construction, built by local craftspeople and students, cave-like ground floor, open bamboo upper floor
Design Application: Conduct community asset mapping before design begins. Hold minimum 3 participatory workshops per project phase. Use 1:1 mock-ups for critical spatial decisions. Design 15-20% of spaces as flexible commons adaptable to community-determined uses. Establish a post-occupancy community stewardship plan. Budget for community capacity building (training local labor in construction techniques).
Section 2: Design Thinking Frameworks
2.1 RIBA Plan of Work 2020 — Stages 0-7
The Royal Institute of British Architects (RIBA) Plan of Work organizes the design and construction process into eight stages. Each stage has defined deliverables, responsibilities, and information exchanges.
Stage 0 — Strategic Definition
Define project aspirations and desired outcomes
Identify site constraints and opportunities
Prepare Strategic Brief (client requirements at strategic level)
Conduct initial feasibility study (order-of-magnitude cost: +/- 40%)
Key deliverables: Strategic Brief, Project Execution Plan, initial Business Case
Stage 1 — Preparation and Briefing
Develop Project Brief with detailed spatial requirements (area schedule per room)
Villa Rotonda: 30.5 m x 30.5 m plan, 6 m x 6 m central rotunda, porticos 5.5 m deep
3.2 Balance
Symmetry: Bilateral symmetry along one or more axes. Creates formality, monumentality, institutional character. Palazzo Farnese (Sangallo/Michelangelo, 1534), National Gallery of Art East Building (Pei, 1978 — triangular symmetry).
Asymmetry: Dynamic equilibrium through visual weight distribution. Requires more sophisticated compositional skill. Barcelona Pavilion (Mies, 1929) — offset planes, pinwheel arrangement. Fallingwater (Wright, 1935) — cantilevered trays balanced around vertical stone core.
Radial Balance: Elements radiating from a central point. Pantheon, Rome (126 CE) — 43.3 m diameter coffered dome. Guggenheim Museum, New York (Wright, 1959) — helical ramp around central void.
3.3 Rhythm
Repetition: Regular intervals of identical elements. Colosseum, Rome — 80 arched bays. Lake Shore Drive Apartments (Mies, 1951) — 5.3 m I-beam mullion spacing on 21-story curtain wall.
Alternation: Two or more elements in regular alternating pattern. ABAB or ABCABC. Doge's Palace, Venice — alternating pointed arches and quatrefoil tracery. Salk Institute (Kahn, 1965) — alternating study towers and open courts.
Progression: Gradual change in size, spacing, or intensity. Jean-Marie Tjibaou Cultural Centre (Piano, 1998) — ten cases increasing in height from 20 m to 28 m. The Broad (Diller Scofidio + Renfro, 2015) — veil perforations varying from dense to open.
3.4 Hierarchy
By Scale: The most important element is largest. Cathedral nave vs. side aisles (Notre-Dame: nave 12.5 m wide, aisles 5.5 m). Civic buildings raised on plinth above surrounding fabric.
By Position: Central position implies primacy. Domed crossing in cruciform church plans. CEO office at building terminus in corporate layouts.
By Contrast: Differentiation in material, form, or detail signals importance. Entrance portal distinguished from repetitive facade (Ronchamp chapel — south wall thick, north wall thin). Lobby double-height within a repetitive office floor plate.
3.5 Unity
Material Unity: Consistent material palette (typically 2-3 primary materials). Therme Vals: Vals quartzite + water + concrete. Exeter Library (Kahn, 1972): brick exterior, concrete interior, teak furnishings.
Geometric Unity: Derived from a single geometric system. Islamic architecture: octagonal geometry generating plan, section, and ornament. Alhambra: muqarnas, tile patterns, and courtyard proportions from shared geometric basis.
Formal Unity: All parts contribute to a coherent whole. Sydney Opera House (Utzon, 1973): all shells derived from a single sphere of 75 m radius (the "spherical solution" of 1961).
Section 4: Precedent Analysis Method
4.1 Seven-Step Methodology
A structured approach to extracting transferable design knowledge from built works.
Step 1: Identify the Design Problem
Define the specific design challenge you are investigating
Frame it as a question: "How can a museum mediate between monumental civic presence and intimate gallery experience?"
Narrow the scope: site strategy, spatial sequence, structural expression, envelope performance, etc.
Water management: rainwater harvesting, greywater recycling
Measured performance: EUI (if available), post-occupancy thermal comfort data
Step 7: Synthesis of Transferable Principles
Identify 3-5 key design principles that can be abstracted from the precedent
State each principle as a transferable rule: "When [condition], then [strategy], because [reason]"
Evaluate which principles apply to your current design problem
Document limitations: what does NOT transfer (climate, budget, scale, culture)

Section 5: Design Critique Framework
5.1 Eight-Dimension Evaluation
A structured method for evaluating architectural proposals. Each dimension is scored 1-5 (1 = deficient, 3 = competent, 5 = exceptional) with written justification.
Dimension 1: Spatial Quality
Does the building create memorable spatial experiences?
Is there a clear spatial sequence from arrival to primary space?
Are there moments of compression and expansion?
Is daylight used as a spatial material?
Benchmark: Therme Vals (spatial procession from dark entry to light bath hall), Salk Institute (compressed lab corridor to expansive court)
Dimension 2: Tectonic Expression
Is the structural system legible and expressive?
Do structure and form reinforce each other?
Are connections and joints detailed with care?
Is there a clear hierarchy of primary, secondary, and tertiary structure?
