Design led renovation and building
Award-winning outdoor living, kitchens and whole-home renovation from a QBCC licensed builder with 25 years of experience
One set of hands, from sketch to handover
Most renovations pass through three or four sets of hands before anyone picks up a tool. Each handover is a chance for the design to get watered down.
At Alpha Plus there is no handover.
Bob Mao designs the project and builds it.
He can tell you on the spot what a detail will cost, what the site will allow, and where the honest trade-offs are — because he'll be the one making the cuts.
What we do
-
Pergolas, patios, decks, carports and structural landscaping — designed as rooms, not add-ons.
-
We handle complete bathroom and kitchen renovations, from redesigning your bathroom layout to make the most of the space, through to relocating existing toilets, showers and vanities. If your household’s needs have changed, we can add new toilets and plumbing facilities, and we take care of the waterproofing, tiling and full fit-out to finish the job.
-
We remove and relocate structural walls, build new structural and internal walls, and modify load-bearing walls in line with engineering designs and the required approvals. We also take on extensions, renovations and general carpentry work.
-
Concept design, 3D hand-drawn visualisation and construction detailing — available as a standalone service if you already have a builder.
Twenty-five years, two continents
Before Bob picked up a carpenter's tools in Australia, he spent fifteen years as an interior architect in Shanghai, running his own practice on projects including Coca-Cola's Pudong offices, a fifteen-floor Holiday Inn, and retail fitouts for Kodak and KFC — over 70,000 square metres of commercial interior work.
After moving to Australia with his family, He retrained from the ground up: a Certificate III in Carpentry, then a Certificate IV in Building and Construction, and nine years of Australian residential sites — framing, heritage church restoration, insurance repairs, and running crews as a leading hand.
Design intelligence and trade craft, in the same person.
It's rare, and you can see it in the work.
