Bautista Arquitectos Turns a Cold Shell in Puebla into a Warm Family House Wrapped in Timber Slats

La Cañada House begins with a problem that many urban renovations share and few solve well. The lot in the Zavaleta neighborhood of Puebla, Mexico, already held a building that was only partially habitable, and its architects describe it as a cold space unsuited to a family. Bautista Arquitectos did not erase it and start fresh. The brief they set themselves was narrower and more difficult: build warmth into a structure that had none.

The finished house, completed in 2018 at 830 m², answers that brief with a short list of materials. Board-formed concrete gives the house its weight, round vertical timber slats wrap the upper volume, and full-height glazing opens the ground floor to a long pool and lawn. What interests us is how carefully the team controls light. Warmth here is less about finishes than about filtering: daylight through slats, lamplight through perforated screens, and low ground lights along the concrete at night.

A Timber Veil Over a Glass Base

The basic section is easy to read. A glazed ground floor carries a closed upper volume, and that volume is screened behind a continuous run of timber slats. At dusk the arrangement reverses: the slats glow from inside and the house reads as a lantern sitting on a transparent plinth. It is a familiar move in contemporary Mexican residential work, but Bautista handles it with discipline, keeping the slat rhythm unbroken across corners.

The corner view with stone steps and agave matters more than it first seems. The planting is sparse and regional, and it keeps the composition grounded. Without it, the slatted box could feel imported from anywhere.

The Slat as a Working Detail

Look closely and the slats turn out to be round, wood-finish profiles fixed to white metal floor tracks with exposed steel brackets and bolts. The team does not hide the fixings, and that honesty pays off. You can understand how the screen is built simply by standing next to it.

On the narrow balcony the louvers run floor to ceiling, so a two-chair terrace becomes a semi-private room. The screen gives privacy from the street while keeping air and partial views. In a dense neighborhood, this layered edge does more for family life than any amount of glass.

Water, Concrete and Stone

A long, narrow lap pool runs parallel to the glazed ground floor and organizes the garden. Board-formed concrete walls frame it on one side, and pale stone paving forms a covered terrace on the other. The pool's slim proportion is well judged: it reads as a line of water, not a resort feature, and it reflects the slatted volume above.

The palette stays tight across these outdoor rooms. Concrete carries the timber grain of its formwork, the stone is muted, and the lawn and green roof soften the edges. That restraint is what lets the timber read as warm against everything else.

Arrival by Steps and a Slanted Column

The approach is choreographed as a sequence of stone steps along board-marked concrete. Low strip lights wash the treads and the textured walls, so the route reads clearly at night without floodlighting. A single slanted concrete column at the entry is the most expressive structural gesture in the house, and it works because it is used only once.

The steps then open onto a courtyard with a lone tree, and the glazed wall beyond reveals the glowing screen inside. You get a preview of the interior before you enter, a small piece of sequencing that rewards the walk.

Interiors Built Around Filtered Light

Inside, the slatted facade has an interior counterpart: a perforated wall lit from behind. It anchors the living room and works as a light source in its own right, giving the space a soft, even glow at dusk. Beside it, a sculpted tree in a pebble bed brings the courtyard logic indoors.

The covered dining area under a timber ceiling shows the same approach. A linear light grazes the concrete wall, picking out its texture, and the round glass table keeps the room visually light. This is where the brief of warm atmospheres is most legible: concrete stays, but it is lit and paired with timber so it never feels raw.

Stair, Skylight and Private Rooms

The timber staircase is lined with recessed vertical light strips and finished with a glass balustrade, while a perforated metal skylight filters daylight from above. It carries the screen idea into the house's vertical core and keeps the circulation from becoming a dark shaft.

The bathrooms move to marble and dark veined stone, with a long timber vanity, a backlit mirror and a freestanding tub. Planters of snake plants sit by the windows in both. The material shift is noticeable, and the rooms lean more toward hotel luxury than the rest of the house, but the timber and planting keep a thread back to the main palette.

Plans and Drawings

The ground floor plan explains much of what the photographs suggest. The site is wedge-shaped, and the long pool and lawn take up its length, with living spaces lined up along the water and a three-car garage absorbing part of the irregular geometry. The pool is not decoration; it is the device that brings order to an awkward lot.

The additional drawings complete the documentation set and are worth reading alongside the plan to follow how the glazed base, the slatted upper volume and the stair relate across levels.

Why This Project Matters

Plenty of houses use timber screens and board-formed concrete. La Cañada House stands out because it treats warmth as a design problem with technical answers. The team inherited a cold, barely usable structure and addressed it through filtering, layering and lighting rather than through decoration. Slats, perforated walls, grazing lights and a skylight all do the same job at different scales.

For anyone working with an existing building on a tight urban lot, the lesson is useful. You do not need a long list of materials to change how a place feels. You need a clear idea of how light should enter and leave each room, and the discipline to repeat it from the facade down to the stair.
