Set on a wide block, the front rooms of the existing terrace had been previously renovated and featured spotted gum timber. The new design proposed to complete the renovation and continue the use of sustainably sourced spotted gum. Exposed steel portal frames function as both architectural and structural elements, allowing for expansive openings and supporting the first floor above. The new living areas step down from the existing floor level to improve the living area’s connection to the garden and allow for a thermal mass concrete floor. This method of construction in conjunction with solar powered hydronic floor heating stabilises internal temperatures throughout the year.
