Coffered ceiling

A coffered ceiling is a ceiling divided by crossing beams into regular recessed panels called coffers. They are usually square, less often polygonal or round. The device comes from ancient and Renaissance architecture, where coffers lightened heavy stone vaults and decorated them. In a modern interior coffers play a decorative rather than structural role: they give depth, rhythm and the feel of an expensive ceiling.

What they are made of. The classic is solid wood: it looks very expensive and lasts long, but it is heavy and costly. For apartments lighter solutions are more common: plasterboard frame structures, beams of MDF or veneered panels, polyurethane beams and mouldings, and plaster ornament for classical interiors. Lighter materials are easier to fix to the slab and can be combined with lighting.

Which interiors. Neoclassical, classical, art deco, studies and libraries, living and dining rooms in large spaces, public areas. Coffers also absorb some sound, which is why they are liked in studies and halls. In a contemporary interior a simplified version is possible: slim beams, a neutral colour, a graphic grid.

Ceiling height. This is the main limit. A grid of deep coffers visually lowers the ceiling, so this construction looks good in rooms with high ceilings. As a guideline from our practice, true coffers are comfortable at about 3 m and above; in a typical apartment with a 2.6–2.7 m ceiling they can "crush" the space. For ordinary heights there is a lightweight option: a flat layout of mouldings on the ceiling with no depth. It hints at coffers without losing centimetres.

Light and sizes. Lighting around the inner perimeter of the cells turns the ceiling into the main feature of the room, but you must plan in advance places for LED strip, power supplies and access to them. Cell size is chosen in relation to the room: a grid that is too fine looks "cellular", one that is too large loses rhythm. It is best to tie the grid to the room axes, windows and light fittings so that the beams do not cut across fixtures and curtain tracks at random.

Typical mistakes: making coffers in a low room; using heavy materials without calculating the fixing to the slab; not coordinating the grid with the chandelier, curtain tracks and ventilation; mixing too many decorative elements in one room. In our projects we show the ceiling on the ceiling and curtain plan and in the elevations so you can see the pattern before installation.
