Haines Street has evolved with Foomann director Jamie’s growing family while being respectful of its 1970s origins. The first renovation updated the fences, gardens and interior, consolidating rooms to create larger, more functional and lighter spaces. The second renovation added a third level with bedroom, bathroom and rooftop deck, allowing the family of four to stay in the house long term.

Materials become lighter and the design more pared back as the spaces ascend. The new level is intended to be enigmatic. The minimalistic form and detailing conceal the complexity of the stepped addition as well as solar panels, other equipment, and the deck, which provides a private space open to the sky and stars.

This renovation is carbon neutral as assessed by Pangolin Associates. Emissions from embodied energy (materials, products and construction) have been fully offset, and the projected emissions through the use of the home (full life cycle) is forecast to be more than offset by the solar array.

The compact scale of Haines and particularly the new bedroom, bathroom and deck is an asset through attention to proportion and orientation. Light-filled, airy and functional, these spaces feel better to occupy as a result of being designed at a size to suit the purpose.
