Welcome to O'Mara Constructions

O'Mara Constructions is a family owned & operated custom home building company, established in 1964. We build anywhere in the Sydney Metro, Hills, Hawkesbury & Blue Mountains area.

O'Mara has vast experience in a wide range of projects, ranging from new homes, house extensions, renovations, second storey additions, townhouses, duplexes, factories or shops. We also complete knock-down rebuilds, new custom built homes (of any design), renovate old or heritage listed buildings or home extensions, always without the owners moving out. We have NO site costs and build on any land, NO exceptions !

But we are different. We are custom home builders, NOT project home builders.

This means we are flexible with inclusions and have NO standard designs. We build from any plans (or can design any new home, extension, first floor addition or renovation). Owners can use materials from any manufacturer or any supplier.

We're not scared of any job. We specialise in difficult sites and unusual construction. We regularly build on sloping sites, in high bushfire areas, on flood affected sites, rural land, narrow blocks, in remote locations or high wind areas. We build using stone, full brick construction, pole homes, mud brick, complex pitched roofs.

We love jobs that are different, it makes are tradesman better at their job and keeps life interesting.

NO job is too difficult. You name it, we build it !

We are centrally located to these areas and have crews based in all areas for easy access to all of these areas. Our costs are the same for each area being based on Hawkesbury, not Sydney inflated building costs. We pride ourselves on personal service with old style country values.

We regularly build on difficult sites, in remote areas, using unusual construction methods, on sloping sites, in bushfire or flood areas. We build projects that other builders won't or cannot. We love difficult jobs, on difficult sites, using new green technology or alternate construction methods. You name it, we build it.
