Grayhouse is a female-led architecture practice based in the South West of WA. Focused on designing homes that are timeless, thoughtful, and deeply connected to their surroundings.

I’ve been drawn to architecture for as long as I can remember, endlessly rearranging my bedroom furniture, painting the walls a new colour and cutting out floor plans from the newspaper.

That early curiosity has grown into a deep passion for creating architecture that is timeless, honest, thoughtful, and connected to the landscape it inhabits.

Following my Master of Architecture at UWA, I spent time on the east coast and in London, travelling across Europe and immersing myself in its incredible architecture. Now, I’m fortunate to call Dunsborough home 

I have a particular love for raw, natural materials and sustainable design methods. Rammed earth has completely stolen my heart. By embracing passive solar design and other sustainable strategies, I aim to create spaces that are gentle on the planet and a joy to live in.

When I’m not working, you’ll find me in the kitchen, sharing love (and probably snacks) gathered around the island bench with a cup of tea. My two little daughters keep life bright and busy, reminding me every day why creating thoughtful, beautiful spaces for the future matters.

For me, architecture isn’t just work — it’s passion, creativity, and adventure rolled into one.

Welcome to Grayhouse.
