Sustainability and a tight budget were the driving features for this bright and airy lean-to extension to a detached 1960s home. Designed by Warc Studio , the timber-and-glass addition houses a spacious open-plan living area, dining space, and kitchen that connect to a rear garden. To meet sustainability requirements, the architects used locally and sustainably sourced timber, stressed resource efficiency , and promoted natural cooling with operable window openings and solar shading fins. Located in the Melbourne suburb of Oakleigh, Australia, the new addition was inspired by the mono-pitched lean-to structures prevalent to the homes in the area. The architects put a modern twist on the seemingly ubiquitous building structure by combining two gabled roofs with differing gradients. “The design program was driven by resource efficiency which was essential to delivering both economic and sustainable objectives,” wrote the architects. “The resulting roof form provides a compact building envelope: the surface area of the additions are around 12% less than if a flat roof / flat ceiling solution had been employed with the same built volume. This in turn translates to increased efficiency of the thermal envelope and reduced capital material consumption.” Related: Old bungalow transformed into a light-filled dwelling with recycled brick Large windows open the new addition up to views and natural light , reducing reliance on artificial lighting. To mitigate solar heat gain, the architects strategically placed window openings and an automated operable roof window for cross-ventilation . Laminated timber fins jut out from the glass panes to provide shade. The roof is lined with white steel sheet lining to minimize solar heat gain. + Warc Studio Via ArchDaily Images © Aaron Pocock
