Casa Cubo: Modern Brazilian Home Revived
Casa Cubo reintroduces a familiar suburban house as a quiet contemporary landmark in Curitiba, Brazil. Estúdio Convexo Arquitetura retrofits the single-family home with a minimalist attitude, sharpening geometry outside and softening daily life inside. The project focuses on clarity, light, and durable materials so the renewed house can absorb family routines while staying visually calm from facade to garden.










A tall cubic volume presses close to the sidewalk, its deep brown facade punctured by precise openings that catch light against the muted street. Inside, the living areas push toward the garden, where glass doors slide away and air moves easily between sofa, countertop, and lawn.
This house is a retrofit, a single-family home in Curitiba reshaped by Estúdio Convexo Arquitetura with a minimalist and contemporary approach. The project focuses on how a restrained palette and clear furnishings can renew an older structure without erasing its domestic scale. Rooms feel calm yet active, tuned for everyday routines rather than showy gestures.
Recasting The Street Front
From the road, the transformation reads in one confident move. A boxy upper volume in a uniform earthy cladding hovers above the recessed garage, turning the former facade into a controlled plane. Narrow vertical cuts and one generous square window break the surface, framing sky and a pocket of greenery while preserving privacy from neighbors. Planting along the entry stair softens the ascent and nudges the eye upward toward the cube.
Living Room As Gallery
Past the front door, the main living room runs toward the rear garden like a quiet gallery. A low gray sofa anchors the center, facing a media wall lined with warm wood slats and balanced by a pale stone fireplace. The floor remains a continuous light surface, so furniture and a few textured baskets carry most of the visual weight. Large glass panes on the garden side slide open, turning the sitting area into an extension of the terrace during mild weather.
Kitchen Wrapped In Timber
The kitchen and bar form the social core, stitched to the living room yet clearly defined by cabinetry and counters. A long peninsula in light wood seats a row of high chairs, their sculpted backs echoing the joinery of the shelving overhead. Behind, white lower cabinets pair with a slim horizontal window that cuts through the wall and frames a band of greenery outside. Stainless appliances and a precise vent hood sharpen the composition while the soft timber keeps it from feeling cold.
Garden Edge And Outdoor Room
At the rear, glass doors fold aside to clear the threshold between dining area and lawn. A stone wall lines the property edge, fitted with a rhythmic series of planters where vines trail downward and catch the sun. The outdoor floor continues the interior’s light finish, so the table and chairs read as one continuous scene stretching from inside to out. A small pergola and scattered pots give the garden a lived-in character that contrasts gently with the disciplined interior.
Quiet Service Rooms
Even the compact bathroom follows the same restrained script. Smooth gray walls, pale wood framing, and a simple white basin keep the room bright beneath a diffuse ceiling light. Storage stays tucked away, allowing a single plant and the reflection of the garden door to add depth rather than clutter. This measured approach repeats across circulation and service zones, so no corner breaks the calm established in the main rooms.
Back on the street, the cubic facade holds its steady expression while life unfolds through the discreet apertures. Inside, neutral finishes and clear furniture lines give the renewed house room to adapt as habits change. The retrofit leaves the structure grounded in its neighborhood yet refreshed, carried by light, modest materials, and a close relationship with the garden.
