Grande Haie Social Housing by P&P Architectes | Residential Architecture in Etterbeek, Belgium
Grande Haie Social Housing revitalizes 1920s Brussels buildings with 50 modern units, blending heritage preservation, contemporary extensions, timber, zinc, and communal gardens.
Nestled in the vibrant and green neighborhood of Etterbeek, Brussels, the Grande Haie Social Housing project by P&P Architectes represents a seamless blend of heritage preservation and contemporary design. Originally constructed between 1924–1925, this pair of residential buildings has been thoughtfully revitalized to accommodate 50 modern social housing units, enhancing both urban density and community living while respecting the area's architectural legacy.


Heritage-Led Architectural Approach
The project celebrates the historical character of Brussels’ 1920s façades, maintaining the street-facing identity through meticulous restoration. Original details, such as entrance doors and heritage elements, have been preserved, while PVC windows have been replaced with authentic timber joinery faithful to the original design. This careful intervention underscores a commitment to continuity, linking the social housing heritage with present-day needs.


Maximizing Light and Space
The south-facing rear façades embrace natural light and openness, enhanced through the reconfiguration of mansard roofs and the addition of generous dormer windows. These modifications respect the original building volumes while improving spatial efficiency, enabling the creation of homes tailored to contemporary living standards.


Contemporary Extensions and Materiality
At the rear, the architecture introduces a modern expression, with vertical extensions clad in standing seam zinc, echoing the original roof material. Staggered balconies create a dynamic rhythm across the façade, offering private outdoor spaces and sunshading for improved comfort. Ground-level treated timber cladding provides a gentle transition to the landscaped gardens, harmoniously integrating the new volumes into their natural surroundings.


Interiors with Historical Character
Interior interventions retain the building’s authentic character, with restored wooden and terrazzo staircases linking past and present. This thoughtful approach reinforces the residential environment’s warmth, material integrity, and timeless design.


Community-Centric Outdoor Spaces
The project reimagines rear gardens as communal and private outdoor spaces, connected through soft pathways and a new passageway via Rue Fort de Boncelles, enhancing pedestrian and cyclist circulation. Shared gardens, seating areas, and a small sports pitch foster social interaction, creating a natural extension of the living environment for residents.

With a total area of 4,192 m², completed in 2025, Grande Haie Social Housing exemplifies how urban social housing can harmoniously balance heritage conservation, modern interventions, and community-focused design.
