Lesson Summary
Lesson Summary
In this lesson, students explore architectural design by creating a home floor plan and developing it into a 3D perspective drawing inspired by professional architectural illustrations like the example shown. Students will learn how architects organize space, communicate function, and suggest depth using line, color, and perspective. The final artwork will combine planning, structure, and expressive rendering using markers and colored pencils.

About Architectural Planning
Architectural planning is the foundation of building design. Architects begin with floor plans, which are top-down drawings that show the arrangement of rooms, walls, doors, windows, and furniture.
When floor plans are combined with one-point perspective, designers can visualize how a space will look in real life—adding depth, proportion, and realism. This process helps architects communicate ideas clearly to builders, clients, and collaborators.
Guided Discussion
Guided Discussion
What is a floor plan, and why is it important in architecture?
A floor plan is a drawing that shows the layout of rooms from above. It is important because it helps people understand how a space is organized and how rooms connect.What kinds of rooms that are in a typical home?
A typical home usually includes a living room, kitchen, dining room, bedrooms, bathrooms, and a hallway.What factors should be considered when designing a home layout?
Important factors include how the space will be used (rooms), movement between rooms (doors) and natural light (windows).How do architectural drawings help communicate ideas to others?
Architectural drawings clearly show rooms, layouts, and details so others can understand the design before it is built.

Key Insight
This drawing is not just decorative—it communicates information clearly. Good architectural drawings are both beautiful and functional.
What You Do
What You Do
Step 1: Floor Plan Planning
Step 1: Floor Plan Planning
Design a home floor plan and label the rooms.
Include at least 4–6 rooms (e.g., living room, kitchen, bedroom, bathroom).
Think about:
How people move through the space
Which rooms should be close together
Where to include doors and windows.
Step 2: Aerial Cutaway Drawing
Step 2: Aerial Cutaway Drawing
Draw walls using thicker lines, inspired by the example.
Add basic furniture to show scale and function.
Step 3: 3D Room Extension into One-Point Perspective
Step 3: 3D Room Extension into One-Point Perspective
Review horizon line and vanishing point.
Extend walls, floors, and furniture toward the vanishing point.
Step 4: Rendering & Details
Step 4: Rendering & Details
Use colored pencils and markers to add:
Flooring textures
Furniture details
Shadows and depth
Step 5: Reflection & Presentation
Step 5: Reflection & Presentation
Students share their work and discuss:
Why they arranged their home the way they did
Which room they focused on and why
What was challenging about planning vs. perspective
Terminology
Terminology
Floor Plan – A top-down drawing showing room layout
Aerial Cutaway – A view that removes the roof to show interior spaces
One-Point Perspective – A drawing system using one vanishing point
Vanishing Point – Where parallel lines appear to meet
Rendering – Adding color, texture, and shading to clarify form and space
