LOCALARCHITECTURE Shades a Swiss Diplomat's Abidjan Residence under a Folded Concrete Roof

Diplomatic housing usually comes in one of two forms: a fortified compound that keeps its host city at arm's length, or a generic villa that could sit in any capital. Villa CROCODILE, the residence of the Swiss Embassy's Deputy Chief of Mission in Abidjan, rejects both. The Lausanne office LOCALARCHITECTURE returns to Côte d'Ivoire after completing the new Swiss Embassy there in 2016. This time the brief is a 305 m² single-storey pavilion that has to work as a family home and as a reception venue for official guests.

What interests us is how few materials the house uses and how hard each one works. Perforated brick, board-marked concrete, glass, timber and terrazzo make up nearly the whole palette. A thin, kinked roof floats over the plan on tapered columns, and a planted courtyard sits at the centre. The repeated diamond opening sets the house's identity more than any gesture of scale. Lead architects Antoine Robert-Grandpierre and Laurent Saurer, with Pedro Vieira, have produced a building that reads as a climatic device first and a symbol second, which is the right order for a house in a hot, humid city.

A Brick Wall That Breathes

The brick walls are the house's public face, and the architects treat them as filters, not barriers. Small perforations run through the coursing, and a single diamond-shaped opening punctures each long stretch of masonry. The effect is almost heraldic: the diamond works as a recurring signature that you recognise from the lawn, the street and the veranda.

Perforated brick has a long history in tropical building because it lets air move while holding back direct sun and casual views. Here the device also solves a diplomatic problem. A residence of this kind needs privacy without looking defensive, and a screen that visibly breathes signals openness even where the plan behind it stays closed.

The Roof as a Floating Plane

Above the brick, a thin concrete slab cantilevers well past the wall line on slanted, tapered columns. The board-marked surfaces of the columns keep the grain of their formwork, so the concrete reads as crafted, not industrial. The slab's edge is kept remarkably slim, and that restraint is what makes the roof look like it hovers.

The deep overhang does the obvious work of shading glass and walls and sheltering the perimeter from heavy rain. The folded profile matters as well. Seen from the corner, the roof tilts and kinks rather than sitting flat, which breaks down the house's horizontal mass and gives a low building a sense of lift against the palms.

Life on the Veranda

The space between brick screen and roof edge is where the house becomes social. A wicker bench against the perforated wall, stepping stones through the grass and a pendant lamp hung under the slab turn the perimeter into a usable porch. This is the zone that will carry the reception programme on warm evenings, when guests spill out from the living spaces.

At twilight the brick screen glows from behind and the perforations turn into a pattern of light points. It is a simple trick, but it reverses the wall's daytime role. What filters sun by day becomes a lantern by night, and the house announces occupancy to the garden without exposing its interior.

A Choreographed Entry

The approach is slow and deliberate. A cobblestone path leads between tapered columns to a recessed alcove, where stepped concrete treads rise to a door glazed with the same diamond motif. Timber slats crown the brick walls of the alcove, softening the junction between masonry and slab.

Inside, the entry corridor pairs a board-marked concrete wall with a timber door and a tall glazed screen that pulls daylight down the passage. The sequence moves you from rough to refined: cobbles, then concrete, then wood. For a building that will welcome official visitors, that measured transition does the work a grand foyer would do elsewhere, at a fraction of the scale.

Interiors Organised around a Courtyard

The living room opens onto a glazed courtyard planted with palms, and this is the real centre of the plan. Terrazzo floors keep the rooms cool underfoot and reflect the courtyard's light deep into the interior. A green sofa and the planted void make the room feel like part of the garden, not something sealed against it.

Timber slatted double doors connect a terrazzo-floored room to a lounge, so spaces can be joined for a reception or closed off for family life. That flexibility is the brief's hardest requirement, and the architects meet it with doors and thresholds rather than extra square metres. At dusk the glazed living room and the diamond-windowed wall glow together, and the line between the public and private house blurs.

Glass, Glow and the Timber beneath

The front elevation at dusk shows the house at its most legible: full-height glazing lit from within, palms in silhouette, the folded roof drawing a single line across the composition. Brick is the house's defining material, but this view makes clear how much of the envelope is actually glass, protected by the overhang above it.

A construction photograph shows timber joist framing laid over concrete posts and rebar, a reminder that the finished surfaces conceal a hybrid build. We would like to know more about how wood and concrete share the structural load. Even without that detail, the image confirms that the house was assembled from layers, each one chosen for a specific job.

Plans and Drawings

The site plans show a compact footprint set back within a garden lot between streets, with a bedroom wing, living and dining areas, and a planted atrium at the core. The courtyard is clearly the organising element: every major room looks into it or onto the surrounding garden.

The elevations and sections explain the roof. Its kink is a profile that rises and falls across the plan, letting the central courtyard sit beneath a lifted edge while the perimeter stays low. The diamond-patterned screen blocks in the elevations confirm that the motif is a system across the whole house, not a one-off ornament.

Why This Project Matters

Villa CROCODILE shows that representational architecture does not need monumentality. A house for a senior diplomat could easily have relied on scale, security perimeters and imported finishes. LOCALARCHITECTURE instead builds identity from a single repeated opening, a roof that shades generously and a courtyard that cools and lights the plan. These are modest tools, and their consistency is what gives the building its authority.

It also extends a relationship between a Swiss practice and a West African city that started with the 2016 embassy. Working with the Abidjan office Architectes Consultants et Associés, the team has produced a building that is legible as Swiss in its precision and as Ivorian in its response to heat, rain and garden life. For architects working abroad on institutional briefs, that balance is the lesson worth studying.
