EF House is a single-family residence located in Leblon, Rio de Janeiro, designed by Studio Ro+Ca across two floors. The project is built around a central premise: to integrate the interior of the house with the surrounding landscape, the Tijuca hillside and the neighborhood's dense vegetation, without compromising comfort or privacy.

On the ground floor, the living and dining area connects directly to the covered terrace through large sliding glass doors. Large-format natural stone flooring runs continuously across both spaces, reinforcing the connection between inside and outside. The terrace accommodates a built-in outdoor kitchen and dining area, sheltered by a structural overhang that provides shading and frames views toward the surrounding greenery.

Slatted wood ceilings follow the transition between interior spaces and the covered outdoor area, acting as a unifying element throughout the project. The same continuity is present in the material palette: natural stone on floors, warm-toned wood in the built-in joinery including shelving, panels, niches and cabinetry, and glass on all openings, composing a consistent palette across all environments

The media room features a full-height wood-paneled main wall integrating shelving, cabinetry and a recessed TV module. The lower portion is finished in a textured gray stone-effect panel, introducing material contrast without disrupting the overall palette. Vertical slatted wood panels on the side walls complement the room's acoustic treatment.

The kitchen is organized around a central island with a white lacquered top and handleless cabinetry, complemented by open wood shelving. The slatted wood ceiling continues uninterrupted from the living areas, reinforcing the material consistency across the ground floor. Large sliding openings bring the surrounding vegetation directly into the space, maintaining the indoor-outdoor relationship that defines the project.

The dining area is anchored by a stone-top table with a sculptural ribbed base, paired with the Cadeira Olga by Arquivo Contemporâneo in wood and leather. A geometric black metal pendant light marks the center of the table, completing the composition.

In the bedrooms, full-height glazing fitted with floor-to-ceiling sheer curtains maintains the visual connection to the exterior while controlling light and privacy. Headboard walls are clad in vertical wood slat panels, consistent with the material language used throughout the rest of the house.
