It’s hard to play favourites with this pair of non-identical townhouses, created for an artist and an engineer. They share a boundary line and design DNA of warm, natural materials, private light-filled interiors, and clever outdoor connections. The challenge with twins is how to share the light equally.

Replacing a single-storey bungalow near Bondi Beach, the twins present different faces to the street, while internally the floor plans are mirrored. Each is designed in an L-shape around three light well/courtyard spaces that draw in light and breezes. The material palette of lightly bagged recycled brickwork with weatherboard and timber window and door frames nods to the coastal vernacular.

Interiors combine the warmth of wood, white-painted brickwork, and cool concrete floors. Sustainable design elements include glazing that maximises light, airflow, and heat exhaust for natural thermal comfort, while solar roof panels and embedded rainwater tanks harvest natural resources to reduce consumption.

Our work is spatially exciting, playful, and robust, tuned to nature and place. 

Architecture should allow us to feel safe & secure, confident & expressive, quiet & reflective. It should make our lives better.

Our team comes from a range of backgrounds and disciplines, united by a passion for design excellence. Our focus on fostering a supportive, inclusive, well-balanced studio environment earned us the Best In Practice prize at the 2020 NSW Institute of Architects Awards.

We pay our respects to Elders past, present, and emerging, and recognise the myriad ongoing ways First Nations peoples have cared for and shaped their natural and built environments across thousands of generations.
