1. Introduction to the Azuma House
1.1 Background of Architect Tadao Ando
Tadao Ando (b. 1941) is a self-taught Japanese architect known for his minimalist concrete designs and mastery of light. A key figure in Critical Regionalism, Ando blends modernism with traditional Japanese aesthetics, emphasizing simplicity, spatial harmony, and raw materials. His work often explores the relationship between nature and built environments.
1.2 Historical and Cultural Context of the Azuma House (1976, Sumiyoshi)
The Azuma House (Row House in Sumiyoshi) is one of Ando’s earliest and most iconic works. Located in Osaka, it reinterprets traditional Japanese row houses (nagaya) in a radical, modernist form. Post-war Japan’s urban density and lack of private outdoor space inspired Ando to create an inward-focused design centered around an open-air courtyard.

1.3 Key Architectural Concepts
Minimalism: Stripped-down form with bare concrete walls and geometric purity.
Light & Shadow: Controlled natural light through strategic openings, creating dynamic contrasts.
Space & Void: The central courtyard acts as a "negative space," connecting divided living areas.
Materiality: Raw concrete (beton brut) contrasts with natural elements (rain, wind, sunlight).
This house exemplifies Ando’s philosophy: "Architecture is the art of organizing space with light."
2. Design Analysis for Model Making
2.1 Spatial Organization (Split-Level Design, Courtyard Integration)
The Azuma House is divided into three sections, with an open-air courtyard at the center, splitting the living spaces.
Split-level design: The house has a two-story structure, but the courtyard forces movement up and down, creating a dynamic spatial experience.
Functional zoning: Private areas (bedrooms, bathroom) are separated from shared spaces (living, kitchen) by the courtyard.
Model-making focus: Emphasize the void (courtyard) as the heart of the design—its proportions must be precise to convey the house’s compressed yet open feel.
2.2 Structural System (Concrete Walls, Modularity)
Monolithic concrete walls: Thick, exposed reinforced concrete defines the structure, providing both support and aesthetic rawness.
Modularity: The house follows a strict rectilinear grid, with walls and openings aligned for geometric harmony.
Model-making focus:
Use laser-cut chipboard or acrylic to simulate the smooth yet heavy concrete texture.
Ensure walls are perfectly perpendicular—any misalignment will disrupt Ando’s precision.
2.3 Light and Shadow Play (Openings vs. Solid Walls)
Controlled openings: Limited windows and skylights create dramatic light/shadow contrasts, enhancing the sense of enclosure and surprise.
Courtyard as a light source: The open sky above the courtyard floods the interior with changing natural light.
Model-making focus:
Experiment with translucent materials (tracing paper, acrylic) to mimic diffused light.
Use angled cuts in walls to show how light enters at specific times of day.
2.4 Materiality (Bare Concrete, Wood, Natural Elements)
Primary material: Exposed concrete (beton brut)—smooth yet imperfect, with visible formwork lines.
Secondary materials: Wooden floors and sliding doors add warmth, contrasting the cold concrete.
Natural integration: Rain, wind, and sunlight interact with the courtyard, making nature part of daily life.
Model-making focus:
Texture techniques: Lightly sand concrete surfaces or use gray matte paint for realism.
Contrast: Use thin wood veneer or balsa for interior elements to highlight material duality.
3. Scale Model Planning for the Azuma House
3.1 Choosing the Right Scale (1:50 or 1:100 for Spatial Clarity)
The Azuma House’s compact yet complex layout requires a balanced scale to showcase its key features without losing detail:
1:50 Scale (Recommended for Detail)
Ideal for highlighting material textures (concrete grain, wooden floors).
Allows interior elements (stairs, sliding doors) to be visible.
Best if the focus is on light/shadow interplay (easier to simulate openings).
1:100 Scale (For Contextual Studies)
Useful for site context (row-house neighborhood).
Faster to build but may lose finer details (e.g., thin concrete walls).
Decision Factors:
Time constraints (1:100 is quicker).
Purpose (Conceptual study vs. detailed craftsmanship).
3.2 Tools and Materials for Model Making
Core Materials:
Chipboard (1–3mm thickness) – For walls and base (mimics concrete mass).
Acrylic Sheets (Clear/Translucent) – For windows, skylights, and light diffusion.
Balsa Wood/Veneer – For flooring, sliding doors, and warm material contrast.
Gray Matte Paint/Spray – To simulate unfinished concrete texture.
Essential Tools:
Precision Knife & Metal Ruler – Clean cuts for sharp edges.
Laser Cutter (if available) – For perfect geometric accuracy.
LED Strip/Fiber Optics – To test light effects in the courtyard.
Sanding Paper (Fine Grit) – Softens edges for a realistic concrete look.
Pro Tips:
Layering Technique: Use tracing paper between acrylic to diffuse light realistically.
Mock-Up First: Build a quick cardboard prototype to test proportions.
3.3 Key Components to Emphasize
The Courtyard (Heart of the Design)
Leave it empty but mark its boundaries sharply.
Simulate weather effects: Add a removable "rain" layer (clear plastic with etched droplets) or a "sunlight" angle (angled LED).
Split-Level Staircase
Highlight the transition between floors—use a contrasting material (e.g., wood veneer) for steps.
Show how it wraps around the courtyard (critical for spatial understanding).
Modular Rooms
Minimal furniture (if any)—just suggest function (e.g., a single block for a bed).
Use removable roofs or cutaways to reveal interior relationships.
Light Openings
Punctured windows: Drill small holes or use translucent film to show how light enters.
Shadow Study: Rotate a light source to mimic Ando’s intended shadows.
4. Step-by-Step Model Construction of the Azuma House
This section breaks down the physical construction process, ensuring accuracy in capturing Tadao Ando’s design principles.
4.1 Base and Layout (Grid Setup, Wall Placement)
Objective: Establish a precise foundation for the model.
Steps:
Base Plate Preparation
Use a 3-5mm thick MDF or acrylic sheet as the base (size depends on scale: ~40x60cm for 1:50).
Apply a grid system (5x5cm squares for 1:50) to align walls perfectly.
Marking Key Elements
Outline the courtyard’s position (exact center) and wall footprints with a fine pencil.
Label zones: Entrance, Living, Bedroom, Staircase.
Wall Assembly
Cut chipboard or acrylic strips (thickness: 1-2mm) for walls.
Dry-fit walls on the grid to verify proportions before gluing.
Tip: Use a T-square and laser level to ensure 90-degree angles.
4.2 Building the Concrete Shell (Precision in Angles and Openings)
Objective: Replicate Ando’s monolithic concrete walls with clean edges.
Steps:
Wall Construction
Glue pre-cut walls vertically onto the base (use cyanoacrylate glue for fast bonding).
Bevel edges slightly with sandpaper for a "cast-in-place" concrete look.
Openings (Doors/Windows)
For windows: Cut rectangular voids (scale: ~1.5x1m in 1:50) with a precision knife.
Cover openings with translucent acrylic (frosted for diffused light).
Staircase Integration
Build stairs from stacked balsa wood or 3D-printed parts.
Align with the split-level design (highlight elevation changes).
Tip: Spray walls with matte gray primer and lightly sand to mimic concrete texture.
4.3 Detailing the Courtyard (Texture, Light Simulation)
Objective: Emphasize the courtyard as the "living sky" of the house.
Steps:
Floor Texture
Use fine-grit sandpaper or a concrete-effect spray for the courtyard floor.
Add miniature gravel (crushed stone or model railroad ballast) for realism.
Lighting Effects
Embed a micro LED strip (warm white) along courtyard edges.
Alternatively, backlight with a phone flashlight during presentations.
Weather Simulation (Optional)
Overhead acrylic sheet with etched raindrops for a "rainy day" effect.
Tip: Keep the courtyard empty—its void is the focal point.
4.4 Final Touches (Context, Human Figures for Scale)
Objective: Enhance realism and readability.
Steps:
Contextual Elements
Add a simplified row-house facade on either side (thin cardboard strips).
Paint the base neutral gray to avoid distraction.
Human Figures
Place 3D-printed scale figures (1:50) near the entrance or staircase.
Alternatively, use wire silhouettes to suggest movement.
Labeling & Presentation
Attach a small plaque with project name, scale, and key features.
Use a removable roof to showcase interiors during critiques.
Tip: Photograph the model under angled light to replicate Ando’s shadow play.
5. Critique and Reflection
This section helps students evaluate their work, learn from challenges, and connect their models to Tadao Ando’s architectural philosophy.
5.1 Common Challenges in Modeling the Azuma House
Students often encounter these technical and conceptual hurdles:
A. Lighting Issues
Problem: Overly bright/dim light simulations that don’t match Ando’s subtle interplay.
Solution: Use diffused LEDs or layered tracing paper to soften light. Test with natural sunlight during presentations.
B. Proportions and Scale Errors
Problem: Courtyard too small or walls too thick, disrupting spatial balance.
Solution: Cross-check dimensions with scaled plans before cutting materials. Print a 1:50 reference grid.
C. Material Misrepresentation
Problem: Concrete textures looking too rough or glossy.
Solution: Spray paint + light sanding for a matte, slightly imperfect finish.
D. Structural Fragility
Problem: Thin walls collapsing or warping.
Solution: Reinforce with internal acrylic ribs or use thicker chipboard.
Discussion Prompt:
"How did your model handle the tension between emptiness (courtyard) and enclosure (walls)?"
5.2 Student Presentations and Feedback
Guidelines for Effective Critiques:
Presentation Format:
Each student gets 3–5 minutes to explain:
Design choices (scale, materials).
Challenges faced and solutions.
How the model reflects Ando’s principles.
Feedback Framework:
Peer Feedback: Use the "I like, I wish, I wonder" structure:
"I like how you simulated shadows with angled cuts."
"I wish the courtyard felt more open—could you reduce clutter?"
"I wonder how rain would interact with your model’s materials."
Instructor Focus Areas:
Accuracy: Does the model match Ando’s proportions and spatial sequence?
Conceptual Depth: Does it communicate light, materiality, and void?
Tip: Photograph models from Ando’s signature angles (low, looking up) for critique slides.
5.3 Connecting the Model to Ando’s Design Philosophy
Use the models to discuss broader architectural themes:
A. Zen Minimalism
"How does your model’s simplicity reflect Ando’s ‘less is more’ approach?"
Key Terms: Ma (negative space), Wabi-sabi (imperfect beauty).
B. Light as a Material
Compare student light simulations to Ando’s quote:
"Light is the origin of all being."Discuss how shadows define the courtyard’s mood.
C. Human Experience
"Does your model make the inhabitant’s journey (entrance → courtyard → rooms) legible?"
Relate to Ando’s belief that architecture should surprise and calm.
