WHO WE ARE

A Family-Run Perth Home Builder, Accountable on Every Project

Mayfair Building Co is a family-owned residential builder led by registered building practitioner Rowan Streater. We take on a limited number of custom homes and renovations across Perth each year, which means the people who quote your project are the same people on site running it. That hands-on model is how we hold the level of detailing and finish that higher-end homes demand.

You can see that approach in our completed work, from the heritage-sensitive Clarendon Cottesloe renovation to new builds in suburbs like Peppermint Grove. Every project is documented in our residential portfolio, so you can judge us on what we’ve actually built rather than what we say about ourselves.

OUR DIFFERENCE

What Sets Mayfair Apart from Other Custom Home Builders in Perth

The difference at the higher end of the market is in the parts you never see in a brochure: the engineering behind a cantilever, the way a heritage facade is retained and tied into new work, the joinery tolerances, the waterproofing on a coastal block. We don’t sell pre-set packages or fixed plans. We start with your site and your brief and work out how to build it properly.

We collaborate closely with Perth’s architects and interior designers, and we’re as comfortable taking a fully documented set of plans to site as we are helping shape an idea early. On renovations like our Clarendon Cottesloe and Subiaco projects, that has meant marrying new work to an existing home without losing the character that made it worth keeping.

What you can expect from a Mayfair build:

Direct access to the owner and your site supervisor, from first quote to final defect
Registered, licensed building practitioners (WA, ACT and NSW) standing behind the work
Honest, itemised pricing of complex detailing before anything is committed
Real comfort with structural complexity: heritage retention, cantilevers, large spans and bespoke joinery
A limited number of projects each year, so yours gets proper attention

Our Custom Home Design and Build Process

Building or renovating a custom home in Perth is a big commitment, so our process is built to keep you informed and in control. We start with your site, your brief and your budget, and we’re honest early about what’s realistic for each. That first conversation usually saves the most money, because it’s where the decisions that drive the budget actually get made.

From there we manage the whole build: design coordination with your architect, council approvals and certification, structural and services coordination, trades, and quality sign-offs at each milestone. You deal with one accountable team rather than a chain of subcontractors, and you’ll always know what stage you’re at and why.

We’re also straight about cost and timeline. The things that move a custom home budget, the slab and structure, the glazing, the joinery and the level of finish, are exactly the things we cost and explain up front, so nothing surprises you late in the build.

BUILT FOR YOU

Architecturally Designed Homes for the Way Perth Families Live

More Perth families are choosing architecturally designed homes over volume builds, and the reason is simple: a home designed around your block, your orientation and the way you actually live will always work better than a plan pulled off a shelf. The trade-off is that these homes ask more of the builder.

That’s the work we do, across new builds and renovations, from compact infill sites to established suburbs like Cottesloe and Peppermint Grove and coastal blocks further out. Our Clarendon Cottesloe renovation shows how a considered design can transform an existing home, while our award-winning Bunbury build shows the finish we hold on a ground-up project.

Whether you already have an architect and a full set of plans, or you’re starting with a site and an idea, we can help you build it properly.

Why Perth Families Choose Mayfair Building Co

When you build with Mayfair, you work directly with the family that runs it. Our founder, Rowan Streater, was named in the WA 40under40 awards, and our Bunbury project won the People’s Choice Award at the 2024 Hart & Co. Kitchen & Laundry Awards, recognition that only comes from craftsmanship that stands up to a close look.

Just as important, we’re properly licensed and accountable. Mayfair holds registered building licences in Western Australia, the ACT and New South Wales (listed in full at the bottom of this page), and the person who signs your contract stays across the build to the final detail.

That combination of recognised craftsmanship, real accountability and a genuine design partnership is why clients who care about how their home is built choose Mayfair.
