House Écorce by Benoit Rotteleur Architecte – A Vertical Cork-Clad Eco Home in the Heart of Malakoff

Nestled in a serene alleyway in Malakoff, just outside Paris, House Écorce by Benoit Rotteleur Architecte redefines compact urban living through sustainable design and bold vertical architecture. Surrounded by charming workers’ houses, old ateliers, and lush vegetation, the residence provides a peaceful retreat for a family of four seeking both connection to nature and contemporary comfort.

A Bold Vertical Concept on a Narrow Urban Plot

Built on a narrow and challenging site, the project demanded an innovative approach to maximize both space and functionality. The architects chose to develop upward, creating a three-level vertical home entirely wrapped in natural cork. Suspended above the street on a refined concrete portico, the structure becomes an elevated “urban cabin,” blending privacy with openness.

This unique cork façade not only defines the home’s organic appearance but also reinforces its ecological ambitions. Cork, being a natural, bio-sourced material, provides exceptional insulation and moisture regulation while ensuring durability and low environmental impact.

Light-Filled Living Spaces and Sculptural Circulation

Inside, House Écorce reveals a warm, minimalistic interior shaped by light, wood, and raw concrete. The first level serves as the main family living space, designed as an open, double-height volume that enhances natural lighting and spatial efficiency. A striking, sculptural staircase anchors the room, subtly separating the kitchen from the living area without breaking visual continuity.

Staircases leading to the upper bedroom levels are cleverly integrated into the built-in furniture, ensuring fluid movement throughout the narrow vertical layout while saving valuable square meters.

A Seamless Dialogue Between Indoors and Outdoors

At street level, the concrete portico forms a transparent connection between the interior and the garden. Framed by glass partitions, the raw concrete staircase at the center acts as a symbolic threshold between public and private zones, guiding visitors from the lively alleyway to the more intimate spaces above.

The garden-facing façade allows the living area to extend outward, creating a peaceful green refuge that enriches daily life.

Sustainable Architecture Rooted in Natural Materials

From its conception, House Écorce was designed as an environmentally responsible dwelling. The cork shell—treated to be hydrophobic for durability—provides superior thermal and acoustic insulation, contributing to year-round comfort. A centrally placed wood stove beneath the double-height ceiling heats the entire home naturally, with warmth circulating efficiently through all three levels.

The combination of cork, wood, and exposed concrete gives the residence a tactile, authentic character while meeting modern sustainability standards.
