A modern small institutional building in India — a neighbourhood health centre or school — the kind of building type this studio programmes.
Unit IVArchitectural Design - IV

Reading the Building Type

Every building type has a logic — learn to read it before you draw it.

≈ 40 min + studio task

A bank is not a school is not a restaurant. Every building type carries its own spaces, adjacencies and special requirements, and the studio learns to read the type — through case studies and typological references like Time-Saver Standards — before drawing. Tour the small institutional and public types the syllabus names, from the bank with its hidden vault to the Indian primary health centre. Knowing the type is half the programme.

Learning objectives

By the end of this lesson, you will be able to — mapped to the course outcomes for Design of Structures I:

1
CO3 · Apply

Read a building type's key spaces, adjacencies and special requirements from case studies.

2
CO1 · Understand

Describe the planning logic of small institutional and public building types.

3
CO3 · Analyse

Use typological references (Time-Saver, Neufert, IPHS) to seed a space programme.

4
CO1 · Apply

Choose the right organisation and zoning for a given building type.

Bank, school, PHC, office

Institutional types

The bank zones around a hidden vault; the school strings teaching off a spine; the PHC keeps a public OPD front and a clinical core; the municipal office is planned inside-out around work-flow.[1, 2]

Zoning around the vault

A bank is planned around security: the vault is designed first (manufacturer-led), central but out of customer sightlines, with a coordinated triangle of teller line, vault and surveillance. Zones separate cleanly — public banking hall and teller counters, consultation, staff-only operations — on a single controlled customer path.[1]

Restaurant, market, gated community

Community & commercial types

The restaurant runs on a one-way kitchen flow; the market segregates wet from dry and people from vehicles; the gated community is a site-planning problem of road hierarchy and clustered blocks.[1, 3]

The one-way kitchen flow Store Prep Cook Serve Wash Dining (~60%) Store → prep → cook → serve → wash — clean and dirty never cross. Kitchen ~25–40% of floor.

The one-way kitchen

A restaurant runs on the one-way kitchen flow — store → prep → cook → serve → wash — so clean and dirty never cross. The kitchen is roughly a quarter to two-fifths of the floor (a rule of thumb), the dining around 60%, and the cook's zone follows the work triangle of fridge, cooktop and sink.[1, 3]

Building-type explorer

Pick a building type and read its key spaces, its one special requirement and its planning note — a starting point for the space programme.[1, 2]

Building-type explorer

Bank

Key spaces
Banking hall, teller counters, vault/strong-room, consultation rooms, back-office, ATM lobby
Special requirement
Vault designed first — central but out of customer sightlines; surveillance triangle
Planning note
Strict public/secure zoning with a single controlled customer path.

Indicative spaces and norms from case studies and typological references (Time-Saver Standards, IPHS, Neufert) — a starting point for your space programme, not a fixed rule.

Vocabulary

Key terms

Building typology

The study of building types and their recurring spatial and functional patterns.

Vault / strong-room

A bank's secure core, designed first and screened from customer sightlines.

IPHS

Indian Public Health Standards — the norms for a PHC's components and population served.

Work triangle

The fridge–cooktop–sink arrangement that minimises a cook's steps.

Kitchen-to-dining ratio

The (rule-of-thumb) share of floor a restaurant gives to kitchen vs dining (~40:60).

Wet vs dry zone

A market's drained perishables area kept apart from dry goods.

Road hierarchy

The graded network — approach, internal, access roads — of a site plan.

Time-Saver Standards

De Chiara & Crosbie's reference for the spaces and norms of each building type.

Apply it

Studio task

Choose one building type from the explorer and do a quick case study of a real example: list its spaces, sketch its zoning, and note the one special requirement that most shapes its plan. Then turn it into a draft space programme for your own version.

In a nutshell

Recap

Every building type carries its own spaces, adjacencies and special requirements — read them before you draw.
Bank around a hidden vault; school teaching off a spine; PHC public-front and clinical-core; office planned inside-out.
Restaurant on a one-way kitchen flow; market segregating wet/dry and people/vehicles; gated community a road-hierarchy site plan.
Start with case and literature studies (Time-Saver, IPHS, Neufert) — knowing the type is half the programme.
