This sustainable heritage extension transforms a dark, disjointed building to a livable and healthy home. Without compromising its heritage charm, the protected H.D. Annear was renovated to provide a modern living space. A sculptural ribbon fascia wraps the building. This unique element ties together old and new whilst creating shaded canopy. All new elements are sunken into the ground, reducing the impact upon the existing. Clever passive design improves the building from a 1 to a 6 star rating. A 25,000-litre underground tank stores the rainwater for re-use in the toilets, garden and pool.
