Arquitectura-G embeds blue concrete core in Portuguese house<\/h2>\n

 <\/p>\n

In Sintra, Portugal<\/strong><\/a>, Arquitectura-G<\/strong><\/a> completes House II, the latest intervention within a long-abandoned quinta de recreio, a rural estate historically devoted to agriculture and leisure. The project forms part of an ongoing sequence of works by the studio’s team, which seeks to conserve and rehabilitate the site\u2019s buildings and reactivate the broader territory.<\/p>\n

 <\/p>\n

Strict regulations limited any change to the building\u2019s external profile, facades, or roof, so Arquitectura-G responded by hollowing out the existing interior, retaining only the perimeter walls, and inserting a new structural body of blue-pigmented concrete<\/strong><\/a>. Rising from the basement cellar, this inserted core incorporates a helical staircase<\/strong><\/a> and extends upward to form the slabs of the upper levels. It culminates beneath a skylight on the first floor, where daylight streams into the central void and organizes the surrounding rooms.<\/p>\n

historic wine cellar reinterpreted as a self-sufficient dwelling<\/h2>\n

 <\/p>\n

Envisioned as a self-sufficient landscape of vineyards, orchards, forests, gardens, and livestock, the Barcelona-based team<\/strong><\/a> of Arquitectura-G transforms this estate under the principles of permaculture, an approach to design that works with natural ecosystems to create sustainable, regenerative, and resilient ways of living<\/p>\n

 <\/p>\n

The building itself, once a hybrid structure combining a wine cellar with living quarters for workers and servants, stood for decades as a fragmented volume of interlinked spaces stitched together by multiple staircases. The architects reinterpret this mixed typology into a single dwelling that preserves the memory of its dual past.<\/p>\n

 <\/p>\n

The blue concrete spine organizes the residence. On the ground floor, an open-plan arrangement of kitchen, dining, and living areas gathers around the staircase. Bedrooms occupy the upper level at both ends of the plan, while a secondary lounge occupies the skylit heart of the house, transforming what had been a utilitarian and subdivided structure into a unified domestic space in Portugal.\u00a0<\/p>\n<\/p>\n
