Builder in Shellharbour
Shellharbour's beachside homes and new estates are made for indoor-outdoor living — and the salt air is hard on a build. We use coastal-grade materials on granny flats, extensions and renovations so they stand up to it.

Full home renovations in Shellharbour
Yes, we take on full home renovations in Shellharbour, not just single rooms. That means the whole house in one go: reworked layout, kitchen and bathrooms, flooring, wiring and plumbing brought up to standard, and the outside tidied up with it, all under one fixed-price proposal and one builder.
Shellharbour has two very different kinds of renovation. The older brick and fibro homes closer to the village usually want the walls opened up and the wet areas replaced, because the layout is the problem more than the condition. The estate homes from the last few decades are more often a fit-out job: new kitchen, new bathrooms, better connection to the yard.
What we do differently on a coastal block is spec for the salt. Fixings, flashings, external hardware and window furniture all get chosen for the air they'll sit in, because a renovation that looks perfect and rusts out in five years hasn't saved anyone money.

We build custom homes in Shellharbour, meaning a house designed around your block and how you live rather than picked from a catalogue of set plans. It's a different process to a project builder: design first, then engineering and approvals, then a fixed price on the house you actually want.
The case for building custom around Shellharbour is usually the block. The newer estates have narrow lots and specific orientations, and a lot of the older beachside land is a shape or a fall that no standard plan sits well on. A design drawn for the block gets the living areas facing the right way and the setbacks working for you.
It costs more per square metre than a project home and it takes longer at the front end. What you get for that is a house without the compromises, and no upgrade list where every change to a standard plan comes back as a variation.
More on our new home buildsHome additions and extensions in Shellharbour
We build ground-floor additions and second-storey extensions across Shellharbour, and on most blocks here the deciding factor is which way you have room to go. Estate blocks are often tight at the back but fine to build up; older beachside blocks are usually deeper, which makes going out the cheaper option.
The common jobs are an extra bedroom or two as the family grows, a bigger kitchen and living area opening onto the yard, and a second bathroom. Adding out at ground level avoids the structural work that a new upper level demands, so it's the first thing we price unless the block rules it out.
Either way it's structural work that adds floor area, so it runs through a Complying Development Certificate or a DA. We handle the design, the engineering and the approval as part of the job.
How we do home extensionsGranny flat builders in Shellharbour
We design, approve and build granny flats in Shellharbour as one job, from the site check through to handover, on a fixed-price proposal. Most blocks here that are 450 square metres or more can take a secondary dwelling of up to 60 square metres of internal living space through the complying development path, which a private certifier can sign off in around 20 days once the documents are complete, without a full council assessment.
Where the flat can go is the first thing we settle on a Shellharbour block. The estate lots around Shell Cove and Flinders are often generous but shaped so the only compliant spot is a corner of the rear yard, while the older blocks closer to the village and Warilla tend to be deeper with more room to choose. Setbacks, sewer lines and any easement decide it, so we walk the block before anyone draws a plan.
Being this close to the water changes the specification, not the price. Fixings, flashings, guttering and window hardware are chosen for salt air, and the flat gets the same wind rating as a house on the same block would.
How we build granny flatsBathroom renovation builders in Shellharbour
We renovate bathrooms in Shellharbour as one contractor holding the whole job: strip-out, plumbing and electrical rough-in, waterproofing to the Australian Standard, tiling and fit-off, with a fixed price before the old room comes out. You don't book five trades and sequence them yourself.
The two jobs we see most here are the original bathroom in a 1970s or 80s brick home near the village, where the layout and the separate toilet are the problem, and the builder's-standard ensuite in a newer estate home that was never sized for two people. Neither usually needs the plumbing moved far, which keeps the cost in the fit-out rather than in the walls.
Coastal air gets into a bathroom faster than any other room. Extraction is designed in rather than left to a standard fan, and we specify tapware and fittings that hold up to salt, because ordinary chrome pits within a few years this close to the beach.
