At Exactus Homes, we’ve successfully completed many home extensions in Perth, transforming older style homes to light-filled and practical spaces. You’ll see plenty of examples, case studies and photos here on our website.

The range of costs for a home extension can vary greatly. Our experience means we can design and construct a home extension that balances your desires for a transformed home and lifestyle, and your budget.

On our website, you’ll see plenty of case studies of homes we’ve extended, inducing the costs in some, and our complete guide to home extensions.


New home builders

We’ve built new homes in Perth, specifically in Wembley Downs, City Beach and Woodlands. We are unlike project builders in that we don’t have a range of plans to choose from and a process that pushes you from one person to another. We specialise in custom home designs and use a variety of innovative construction methods.

We primarily build in timber-frame, which has significant advantages over double-brick construction. These advantages include a (much) faster build time and energy-efficient, innovative cladding can be applied over frames. Advanced thermal cladding or insulation will achieve a superior energy rating compared to double-brick. However, if desired by our clients, we build in double-brick as well.


Home renovations

A home renovation is something that’s never a regret. Most people wish they did it sooner! The most popular home renovations are bathroom renovations and kitchen renovations. These rooms don’t typically pass the test of time. Cabinetry deteriorates from overuse, the wet environment degrades tiling and benchtops, and designs date.

Kitchen renovations

A stunning kitchen renovation will transform everyday life. With drawers that gently close, a space for every appliance and sparkling sinks and tapware, a new kitchen is a joy to cook in.

Bathroom renovations

Renovating a bathroom is incredibly rewarding.. There’s nothing more depressing that looking at decades of bathroom grime, dull tapware and ugly tiles. A fresh and bright bathroom makes everyday better.
