Multi-Space, Multi-Level Planning
Several spaces, more than one level — organised, zoned and connected.
The earlier studios worked mostly in plan, on one level. Design IV steps up — several related spaces arranged over more than one level, at small scale. (For the studio groundwork, see Design II.) The new skills are organising spaces, zoning them sensibly, and tying them together with horizontal circulation and simple vertical movement. Multi-level is not high-rise — it just means you must think in section as well as plan.
Learning objectives
By the end of this lesson, you will be able to — mapped to the course outcomes for Design of Structures I:
Describe the five spatial organisations and choose one for a given brief.
Zone a plan by public/private, served/servant and noisy/quiet.
Plan horizontal circulation and simple vertical movement across levels.
Explain why multi-level planning is read in section, not only in plan.
Organising and zoning spaces
Ching gives five ways to organise spaces — centralised, linear, radial, clustered and grid — and the first move is to zone the brief: public from private, served from servant, noisy from quiet.[1, 2]
Around a centre
A centralised organisation gathers secondary spaces around one dominant central space — stable and introverted (a hall with rooms around it). A radial organisation extends linear arms outward from a central space — extroverted, reaching into its site.[1]
Circulation, served and servant
Separate served (primary) from servant (supporting) space, keep horizontal circulation legible, and plan simple vertical movement — stair, ramp, a small lift — with the structural grid aligned floor to floor.[3, 4]
Kahn's distinction
Louis Kahn split space into served (the primary occupied rooms — classrooms, offices, the hall) and servant (the supporting spaces — stairs, corridors, toilets, services). Recognising which is which gives a plan clarity and hierarchy.[3]
At a glance
| Aspect | One | The other |
|---|---|---|
| Two organisations | Centralised: around a dominant centre | Linear: strung along a path |
| Space hierarchy | Served: primary occupied rooms | Servant: stairs, corridors, services |
| Two movements | Horizontal: corridors on one level | Vertical: stairs, ramps, lift between levels |
| Scale of stacking | Multi-level: 2–3 floors, simple circulation | High-rise: towers, lifts, fire systems |
| What to plan together | Plan (the layout) | Section + structure (the stacking) |
Key terms
How spaces relate — centralised, linear, radial, clustered or grid (Ching).
Grouping spaces by compatibility: public/private, served/servant, noisy/quiet.
Primary occupied rooms vs the supporting/service spaces that enable them (Kahn).
The network of movement linking spaces — corridors, lobbies, stairs.
Movement between levels — stairs, ramps and lifts.
A modest structural grid whose lines align floor to floor in a multi-level building.
Multi-level just means more than one floor with simple vertical circulation — not a tower.
Which spaces must be near which — the proximity logic a plan must satisfy.
Studio task
Take a small two-storey brief and sketch it two ways — as a centralised organisation and as a linear one. Mark the served and servant spaces, and show where the stair, ramp and (if needed) lift go in section. Note which organisation handles the multi-level circulation more economically.
Self-assessment
1. Stairs, corridors and toilets are best described as —
2. Per NBC 2016, a stair landing is required after a maximum of —
3. An organisation that groups spaces by proximity without strict geometry is —
