clt passivhaus in balgowlah (nsw), 2019
timelapse: clt installation in just 15 hours
this 2-storey extension to an existing house from the late 1920s was erected in a tight backyard in Balgowlah. The budget of the house was very modest, though the quality needed to be decent to achieve a certified Passivhaus rating. The entire CLT structure was prefabricated offsite, including the stair and cutouts for lighting, power and equipment, and installed in just 15 hours over 2 days with the help of a 130t mobile crane.
The interior of the building will feature fully exposed timber walls, floors and ceilings, which in combination with the Passivhaus ventilation system will ensure a healthy indoor environment. The building is anticipated to work year round without the need for heating and cooling, due to the airtightness of the envelope, high insulation and triple glazed timber windows.
