The project involved an attic conversion within an existing house, demolishing the rear building with a new two storey steel and timber framed extension with a funky roof, and a rear cabana. The new extension was supported on a series of steel frames and a feature rear façade with large window openings and a double storey atrium for the entire width of the façade. Keeping the façade stable and tied back to the building without any structure crossing through the atrium proved challenging, which was only made more difficult by the fabrication and site considerations. Collaborating closely with the fabricator enabled us to create a solution for connecting large pieces of steel in a way that was practical for delivery and installation on site around the existing pool and whilst also ensuring the durability of the steelwork exposed to the elements. Partridge undertook detailed structural analyses and design of many different iterations, working closely with the architect and builder to achieve the desired mix of cost, aesthetic, and practicality. Ensuring the structure had the thinnest silhouette possible involved carefully choosing locations in which to conceal structure and creatively joining off-the-shelf structural sections to make slender, yet strong compound sections.
