Elphin House is a project designed by Julie Firkin Architects in 2016. This addition opens up to an established back garden in the leafy suburb of Ivanhoe. Seven metre wide doors slide away and broad timber steps descend into the garden. A massive but finely detailed facade screen modulates northern sunlight in the main living area. The algorithmic pattern of the facade screen was inspired by foliage and textile patterns. Photography by Christine Francis.
