    Our Comfortable, Sustainable Delightful Projects:

Every project we work on is shaped by the people who live there. No two homes - or families - are the same, so our approach is always tailored, thoughtful and grounded in how you want to live.

As Canberra-based residential designers, we combine strong design thinking with practical construction knowledge to create homes that are simple, cost-effective and highly functional. Our focus is on improving how your home feels and performs - enhancing natural light, flow and comfort while making smart use of your budget.

A key part of our work is designing energy-efficient homes suited to Canberra’s climate. Using solar passive design principles and detailed thermal modelling, our new homes typically achieve NatHERS energy ratings above 8.0 stars. For renovations, we regularly transform older homes from less than 2 stars to over 7.0 stars - significantly improving comfort, liveability and long-term performance.

We work across a range of project scales, from targeted renovations and extensions through to full knockdown rebuilds. Most renovation and extension projects sit between $300,000 and $750,000, while new builds are typically in the $750,000 to $1.25 million range. We are also experienced in delivering both smaller, staged renovations and larger, high-performance homes.

Whether you’re renovating, extending or building new, our goal is the same: to design a home that works beautifully now and is ready for you to enjoy into the future.

We acknowledge the Traditional Owners and Custodians of country throughout the lands on which we work including the Ngunnawal, Ngarigo and Yuin People.

We acknowledge and respect their continuing connection to land, waters and community. We pay our respects to the people, the cultures and the elders past, present and emerging.
