Few residential buildings carry as much weight in Brazilian architecture as the Copan, Oscar Niemeyer's serpentine slab in central São Paulo, completed in 1966. Thousands of people live behind its brise-soleil, and for a generation of local designers, getting to work on one of its units is close to a rite of passage. Balaio Arquitetura got that chance with an unusual brief: the client was the studio itself. Lead architects Gabriel Luqui and Gabriela Russo renovated this 85 m² apartment, previously a rental, as their own home.

What makes Copan Apartment A worth your attention is restraint, which is harder than it sounds when the architects are also the residents. The renovation starts from a close reading of the existing flat. It exposes the original concrete, keeps the window walls and the building's character intact, and adds a layer of custom furniture and practical finishes shaped around the couple's daily routine. The result has no showpiece move. Instead it settles into the building and organizes everyday life around light and a few well-placed pieces of joinery.

A Living Room That Lets the Concrete Talk Back

The living room sets the palette for the whole apartment: a rust velvet sofa, a mustard armchair, walnut shelving and a pair of plywood lounge chairs, all set against board-marked concrete and the Copan's gridded glazing. On paper that is a lot of warm color. In the room it works because the concrete wall behind the sofa absorbs it. The rough grain of the formwork gives the upholstery something to push against.

Look at how the furniture faces the window wall rather than the television. The plywood chairs are angled toward the city and the daylight, which is the clearest sign of the brief's priority. In an apartment where the facade does most of the environmental work, orienting the seating toward it is a quiet, correct decision.

Reading the Bones Before Adding Anything

The most confident decision here is what the architects left alone. Columns and walls show their board marks, and in one close-up a column base meets the new cream resin floor with a small hole and a rust stain still visible. Many renovations would patch that over. Balaio lets it stay, and the apartment reads as a chapter in a sixty-year-old building rather than a fresh insert.

The beams overhead are painted white instead of left raw, which is a sensible split. Raw concrete at eye level gives you texture and history, while the painted ceiling bounces daylight deeper into the plan. The entry handles this balance well: a rough timber bench, a wall-mounted shelf column and an exposed electrical panel sit together without anyone pretending the services aren't there.

Dining Under the Beams

The dining area centers on an oval walnut table with green upholstered and round-backed chairs, lit by a conical pendant and a hanging planter. The curved table is a smart choice in a unit organized by the Copan's rigid structural grid. It softens circulation around the corner and keeps the space from feeling like a corridor with a table in it.

A glass-fronted timber display cabinet marks the threshold to the kitchen, holding glassware and plates in view. It does two jobs at once, storage and a soft divider, and that double duty runs through the project's joinery. In 85 m², furniture that only does one thing is a luxury the plan can't afford.

A Galley Kitchen Painted Into the Floor

The kitchen is a narrow galley, and the architects don't fight that. Cream cabinets, a speckled stone backsplash and tall walnut storage line the walls, while the floor shifts to mustard. Seen from the corridor, that ochre floor marks the kitchen as a distinct zone without a door or a step. It is wayfinding done with a single material change.

The corridor itself runs in pale resin under white beams, linking living spaces, kitchen and bedroom. Built-in bookshelves line part of the route, so the hallway carries storage instead of being leftover space. A coffee station of walnut cabinetry and open shelving sits nearby, an example of designing around a specific routine rather than a generic program.

Joinery for Books, Records and Small Rituals

Here you can see that the architects designed for themselves. A corner reading nook pairs the mustard armchair and ottoman with built-in shelves, trailing pothos and a white tiled bench stacked with vinyl. A floating teak cabinet in a white niche holds a turntable, speaker and lamp. These are specific objects belonging to specific people, and the joinery is sized for them.

The material detailing rewards a close look. Terrazzo-look shelves, white mosaic tile surfaces and teak doors bring texture at hand height, where you actually touch the apartment. We'd argue this is where the custom furniture earns its place: not as statement pieces, but as surfaces tuned to records, books and morning coffee.

Working With the Copan's Screens and Views

The balcony sits behind a perforated white concrete block screen, with potted tropical plants on a yellow floor and a neighboring tower beyond. That screen filters sun and frames the city in small pieces, the same climatic logic that drives the building's facade. The renovation keeps it and lets plants and a single wire chair fill the space.

A plywood desk with a guitar hung above it faces a tall window onto surrounding towers. Working from home in central São Paulo means living with density, and this corner accepts it, turning the skyline into the backdrop of a workspace instead of something to screen off.

Plans and Drawings

The floor plan shows how compact the program is: dining room, living room, bedroom, bathrooms and a kitchen highlighted in peach. The kitchen tint mirrors the colored floor on site, confirming that the zoning by material was planned from the drawing board and not added as decoration.

Why This Project Matters

Renovating inside an icon carries a temptation to either freeze it or overwrite it. Balaio Arquitetura does neither. By exposing the concrete, protecting the light and the facade, and putting their design effort into furniture and finishes, they show how a heritage-grade building can absorb a contemporary life without losing its character. It is a useful model for the many modernist apartment blocks across Brazilian cities that now need careful updates rather than gut renovations.

It also makes a case for designing from routine. Because the architects are the residents, every built-in answers a real habit: where the records go, where coffee happens, where the dog sleeps. Plenty of interiors claim to be personal. This one shows what that looks like when the brief comes from daily use, carried out with collaborators including Imaliza for construction and Evanildo Soares for engineering.
