This Wilton residential project required a BASIX Certificate aligned with the latest NSW sustainability requirements.
The design included modern architectural features, large glazing areas, and open‑plan living — all of which needed careful modelling to achieve compliance without compromising the client’s vision.
The Leppington project involved a modern residential design typical of the area’s growing estates.
With a mix of open‑plan living, feature glazing, and a strong architectural focus, the assessment required careful modelling to ensure compliance without adding unnecessary construction costs or compromising the design intent.
The Austral project involved a contemporary two‑storey home featuring large upper‑level glazing, open‑plan living, and a strong architectural focus.
Multi‑level designs often introduce additional thermal challenges, particularly around heat loss on the lower level and heat gain on the upper level.
