Unit IVArchitectural Design II

Design Exercises I — Single Spaces

Designing one room well — function, the body and passive comfort.

≈ 40 min

Before a building, a room. The first set of exercises designs a single functional unit — and designing one room well is where standards, anthropometrics and method first meet a real, if simple, brief.

Learning objectives

By the end of this lesson you will be able to — mapped to the course outcomes for Architectural Design II:

1
CO1 · Understand

Treat a single room as the elementary unit of architecture.

2
CO3 · Apply

Design a functional unit to its anthropometric and accessibility standards.

3
CO3 · Apply

Apply passive-comfort strategies suited to the Indian climate.

4
CO1 · Apply

Resolve horizontal movement and use within a single bay.

One space, done well

The room is the beginning

A single room is the elementary unit of architecture; design it from its function and it teaches the fundamentals in miniature. Select a topic.[1, 2]

The room is the beginning

A single room is the elementary unit of architecture — Louis Kahn called the room ‘the beginning of architecture’. Designing one well teaches everything in miniature: function, the human body, light, movement and structure, without the complication of many spaces.[1]

The room is the beginning light Function, body, light, movement and structure — a single room teaches them all in miniature.

ExerciseWhat drives the plan
Accessible toilet1500 mm turning circle, grab bars, ≥ 900 mm door
KitchenThe work triangle (sink–hob–fridge); ~900 mm counters
Hostel roomBed, desk, wardrobe; daylight and ventilation
Shop / snack barDisplay, counter, customer flow; barrier-free entry
PavilionA single open structure — roof, shade, gathering
Passive design

Comfort without machines

A single space is the place to learn passive design — orientation, cross-ventilation, shading and thermal mass — which cost nothing and do most of the work in the Indian climate.[3]

Comfort without machines thermal mass harsh sun → shade it cross-ventilation Orient, cross-ventilate, shade and use thermal mass — they cost nothing and do most of the work in India.

Everyone gets in

Even a small public unit must be barrier-free — a 1:12 ramp, a clear ≥ 900 mm entrance, an accessible WC. Designing access in from the first room is the habit to build.[4]

Self-assessment

1. Why do beginning studios design a single room first?

2. The plan of an accessible toilet is driven mainly by:

3. A good passive strategy for a single space in India is to:

In a nutshell

Recap

A single room is the elementary unit — design one well and you learn the fundamentals.
Start from function: the toilet from its turning circle, the kitchen from its work triangle.
Build in universal access from the first room — ramp 1:12, ≥ 900 mm door, accessible WC.
Use passive comfort — orientation, cross-ventilation, shading, thermal mass — and keep movement horizontal.
