CLT Addition – Passive House

This sustainable, two-storey addition to an existing Californian bangalow in Balgowlah comprises of a kitchen and dining with lounge area downstairs and master bedroom, en-suite, WIR and study upstairs totalling in 110m2 of area.

The addition was erected very efficiently and precisely, with tolerance of 2mm, just within 15 hours. This structure was made offsite using CLT (cross-laminated timber) then craned and installed on site.

It was designed and build to Passive House standards, to provide the owners with healthy indoor environment that is comfortable in temperature and humidity.
