South Western Australia. A place of natural extremes. Where raw untamed beauty meets surprising tranquillity. It's no wonder so many find their place here.

We believe that the homes we build should harness the natural beauty of our surroundings whilst reflecting the style that helps you live the life you want to live.

What does it cost to build with South West Building Co?

You’ll be surprised to know a quality custom home is more affordable than you’d think! We are very competitive with our pricing and are keen to have your business.

If you want an idea and are comparing with a standard project build, the full package home (including painting, floor coverings, air-conditioning), prices start from around 300k for a standard 4 bedroom, 2 bathroom home (~$1100 per/sqm).

If you love our timber framed “Hamptons” country/beach/barn style builds with the loft design, they are great value from 350k.

Can you choose your own architect or designer?
