On a compact triangular site in Sydney’s east, Platform House makes a virtue of constraint. Its design inverts the traditional floor plan, housing bedrooms on ground level and adding a new pavilion that celebrates the site’s geometry in an elevated platform for everyday living.

While the bedrooms are surrounded by a cool, secluded garden, the platform upstairs channels light and views from all directions, with openings carefully cut to frame trees and vistas to the city. The idea of ‘opposites’ extends from design through to materials. Studioplusthree conceptualised the platform as a ‘coconut’ – with its dark outer skin of charred timber (an old Japanese technique) wrapping a smooth, warm white interior. Inspired by Islamic architecture, bronzed metallic screens offer refined ornamentation while filtering the movement of light, trees and afternoon sun. On a site of just 376 square metres, this innovative, richly crafted house is a joy to inhabit and experience.

Tour experience

Sydney Open visitors will enjoy a tour of this recently completed home, led by its designers and owners, who collaborated closely on the project. As well as allowing visitors to experience these bespoke spaces, the tour will touch on the genesis and influences of the design and the construction process, with opportunities to ask questions throughout.
