LUXURY HOME BUILDERS SYDNEY
BUILT TO AN EXCEPTIONAL STANDARD
A luxury home should fit the way you actually live, your site and your outlook, not a standard plan. We are a family-run builder bringing an award-winning custom home standard to Sydney, and we stand behind every home we build.
THE BRIEF
Luxury Home Builders Who Build to an Exceptional Standard
A luxury home in Sydney is judged in the details 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 harbourside block. We do not sell pre-set packages or fixed plans. We start with your site and your brief and work out how to build it properly.
Mayfair Building Co is a family-owned builder led by registered building practitioner Rowan Streater. We take on a limited number of custom homes and renovations, which means the people who quote your project are the same people running it on site. You can judge us on what we have actually built, documented in our completed homes, rather than on what we say about ourselves.
CRAFT AND DETAIL
What Sets Mayfair Apart as Luxury Home Builders in Sydney
Sydney’s best blocks are rarely easy. Steep sites, sandstone, harbour and ocean outlooks, tight streets and heritage controls all raise the bar on what a luxury build demands. That is exactly the work we do, and we are as comfortable taking a fully documented set of architect’s plans to site as we are helping shape an idea early.
We collaborate closely with architects and interior designers, and we hold the level of detailing and finish that higher-end homes demand. On complex sites and sensitive renovations, that means marrying new work to an existing home without losing the character that made it worth keeping.
What building a luxury home with Mayfair includes:
Direct access to the owner and your site supervisor, from first quote to final defect
Registered, licensed building practitioners in New South Wales 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
How We Plan and Build a Luxury Home in Sydney
Building or renovating a luxury home in Sydney is a significant 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 are honest early about what is realistic for each. That first conversation usually saves the most money, because it is where the decisions that drive the budget are actually 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 always know what stage you are at and why. The trades that shape a luxury result, from carpentry, plumbing and electrical through to bespoke joinery, are coordinated from the start.
We are also straight about cost and timeline. The things that move a luxury home budget, the 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.
DESIGNED AROUND YOU
Luxury Homes Designed Around the Site, the Light and the Way You Live
The point of building custom is a home that could not have been built any other way. On a harbourside block in the Eastern Suburbs, that might mean lifting the living areas to capture the water and the northern light. On a leafy North Shore site, it might mean privacy, established trees and a seamless connection to the garden.
Where the glass goes, where the home opens up and where it shelters, and how the finishes are resolved, are the decisions that separate a genuinely luxury home from an expensive one. We work alongside your architect, or bring one in if you need, and hold the finish to the standard the design deserves.
Trusted to Build Sydney’s Finest Homes
You can judge a luxury builder on the homes they have finished and on whether the detail stands up to a close look. 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. That kind of recognition only comes from craftsmanship that holds up in person.
Just as importantly, we are properly licensed and accountable in New South Wales, with registered building practitioners standing behind the work (listed in full at the bottom of this page). We are already building in Sydney, including a residential project underway in North Bondi, and the person who signs your contract stays across the build to the final detail.
