Haines Street has evolved with a growing family while being respectful of its 1970s origins. The project involves an enigmatic third level addition containing a third bedroom, bathroom and rooftop deck with outdoor bath. The project is carbon-neutral with embodied energy independently measured and offset. The form and detailing conceal the complexity of the stepped addition. The compact scale of this 100m2 home is an asset through attention to proportion and orientation. Light-filled and functional, these spaces feel better to occupy as a result of being designed at a size to suit the purpose.
