Designing a car showroom: what the brand standard demands.

A car showroom is the one building type where the architect has three clients at once: the investor who pays, the manufacturer who approves, and the authority that issues the permit. The design happens inside that triangle, and it is the triangle rather than the architecture that governs the programme.

The standards manual: what is genuinely fixed

Every marque has a document setting out how its showroom must look and work. Normally beyond discussion:

• Identity: the mark, its size, mounting height, corporate colours, the way it is lit.
• Elevation and interior materials: often one named system from one named manufacturer, not "something similar".
• The customer sequence: from entrance through welcome, display, advisor desks, to handover. The order is deliberate and the brand does not change it.
• Minimum areas and bay counts: display, service reception, workshop bays.

What is open

The massing and its relationship with the site, the roof, the structure, the services, parking layout, the manoeuvring yard for transporters, daylight in the workshop. This is where the architecture lives: and where it is decided whether the showroom becomes a building or a box with a logo on it. Experience with a particular marque shortens this part most, because you know in advance what the manufacturer will ask about.

Manufacturer approval: the stage everyone leaves out of the programme

The design goes to the manufacturer for sign-off, usually twice: after the concept and after the building design. Comments come back, are incorporated, and the design goes again. That loop takes time and does not depend on how fast the architect works, it depends on the calendar of the department reviewing it, often abroad. Investors planning an opening date almost always underestimate this stage rather than the design itself.

Service is the other half of the building

The display is what people see, but the service side decides whether the dealership sustains itself. Entry, reception, bays, parts store, oil separation, ventilation, slab loading, clear height over the lift. That brief carries hard requirements and it usually sets the overall envelope, which is why it is where the work starts, not the elevation.

Where our experience comes from

We have designed showrooms for premium marques, including BMW facilities for the Bońkowscy group. Those buildings went through the manufacturer's full approval loop and they are built: which is the source of the only knowledge that counts here: where the standards manual gives way, and where it never will.

In a showroom the architect has three clients at once: the investor, the manufacturer and the authority. The programme is set by the second one.
