Designed by Urbanline studio [ALI MALEK-ZADEH] & atelier rzlbd [REZA ALIABADI], Shaft House funnels sunshine into the heart of the home is located in Toronto, Canada. Shaft House attains the objective of creating an economically efficient, sustainable and responsive housing design through function and innovation. The structure of the house revolves around a central shaft, which is open to all levels of the house and lit by a skylight and south facing windows; this allows for natural ventilation and maximises air circulation. This is how; this 16-ft-wide project manages to be innovative in its formal complexity and spatial configuration while respecting all the city bylaws. Materials employed (rusted steel, aluminum, and untreated wood) are more sustainable than those used traditionally (brick, shingle, and stone, etc.) As the building ages, these organic materials age along with it and the house eventually blends into the vernacular oeuvre of the neighbouring dwellings.
