Garage Conversions in Gilston

Our garage conversions service in Gilston

What older homes here tend to hide in Gilston

In older stock the surprises are consistent: undersized or cloth-wrapped wiring, waste lines that no longer meet fall requirements, out-of-square openings, asbestos sheeting in wet areas and eaves, and floor levels that step between additions. We check for all of it at inspection and price the fix rather than leaving a provisional sum that blows out later. A mix of 1980s brick homes, timber cottages and larger acreage residences, many with outbuildings, verandahs and decks that need renewal.

Approvals and compliance

A garage is not habitable space until it is approved as habitable space. That means ceiling height, natural light and ventilation, insulation, floor level above the surrounding ground, moisture protection and egress all have to be brought up to standard, and on-site parking usually has to be replaced. We prepare the drawings, engage the engineer and run the private certifier so the room is legal and shows up correctly when you sell.

Making it feel like part of the house

The giveaway on a bad conversion is the door opening, the floor step and the ceiling height. We infill the garage opening with properly framed windows and cladding that matches the facade, raise or level the slab where needed, line and insulate walls and ceiling, and carry the same skirting, architrave and paint through from the rest of the home so the room reads as original.

Comfort, services and storage

Insulation to walls and ceiling, new power and data circuits, lighting, ceiling fans or split-system air conditioning, and where the brief calls for it, plumbing for a bathroom or kitchenette. We also plan replacement storage - built-in joinery or an external shed - because that is the thing owners miss most after the garage is gone.

What garage conversions cost in Gilston (2026)

A single garage conversion generally runs $25,000-$45,000 finished. Double garages, self-contained studios, or conversions with a bathroom or kitchenette typically land $50,000-$90,000 depending on services runs and finish level. Prices move with access, the condition of what is already there, how much structural work is involved and the level of finish you choose. We confirm all of that at the inspection and price your Gilston job rather than quoting from a range.

How long garage conversions take

Most garage conversions take 4-8 weeks on site, plus 4-8 weeks beforehand for drafting, engineering and building approval.
