Common questions
What does Ovas Build build?
We build granny flats, home renovations and extensions, kitchen and bathroom renovations, carpentry and joinery. We also build decks, pergolas and carports, new homes, duplex and dual occupancy projects, and knockdown rebuilds. It is all residential work, with one builder for the design, the approvals and the build, from the first site visit to handover.
Does Ovas Build handle approvals for its services?
Yes. For granny flats we handle the design, the approvals and the engineering, then build the job turnkey. For decking and for pergolas and carports, the approvals are handled too. Across the other services we handle the permits and engineering, whether a job goes through complying development or a full development application.
What kinds of granny flats can Ovas Build build?
We build custom granny flats designed for your block, from studios through to two-bedroom homes. They are built turnkey, so they are ready to live in or rent out. The services page also links to guides on granny flat cost, designs, builders in NSW and kit versus custom builds, so you can plan before you commit.
What does a kitchen renovation with Ovas Build include?
A kitchen renovation is a new kitchen built around how you actually cook. It has custom cabinetry with soft-close hardware, engineered-stone or laminate benchtops and smart storage. We coordinate the licensed plumbing and electrical, so you deal with one builder for the whole job rather than managing each trade yourself.
What does a bathroom renovation with Ovas Build include?
We do full bathroom renovations from stripout to the last bead of silicone. That covers waterproofing, tiling, vanities and fixtures. We coordinate the wet trades, so the room is watertight and finished to last, and you deal with one builder from the start of the job through to handover. Fixtures and finishes are chosen with you, so the result suits the room.
What joinery does Ovas Build make?
We make custom joinery to cabinet-maker standard. That includes built-in robes, entertainment units, pantries, laundries, office fit-outs and outdoor barbecue cabinetry. The boards are moisture-resistant and built for the coast, and the joinery can be part of a wider renovation or built as a job of its own. It is built to the same standard as the rest of our carpentry work.
Does Ovas Build build new homes and duplexes?
Yes. We build custom new homes across the Illawarra, the Shoalhaven, the Southern Highlands and Macarthur, designed for your block and built by one team from approval through to handover. We also build duplexes and dual occupancy homes, attached or detached, and knockdown rebuilds, where the existing house is demolished and a new home is built on the same block.
