Local prefabricated building specialists Modscape designed an energy-efficient extension for a Melbourne family residence wrapped in black-stained timber and blackbutt vertical cladding. On the first floor of the addition, light-filled living spaces overlook views of the backyard through floor-to-ceiling windows and sliding glass doors. Solar passive principles were applied and cross ventilation was optimized with access to natural light that pours through the double-glazed windows and thermal break frames.
