Welcome to O'Mara Constructions

O'Mara Constructions is a family owned & operated contract building company, established in 1964. We build anywhere in the Sydney Metro, Blue Mountains & the Central Coast.

O'Mara are building contractors of a wide range of projects ranging from new homes (simple designs to luxury mansions), house extensions or additions, first floor 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 !

We are Contract builders, NOT Project Home Builders. We are flexible with inclusions and have NO standard designs. We build from any plans (or can arrange designs to be completed) and owners can use materials form any company manufacturer or supplier. We allow owner supplied materials or non-structural work by owners nominated sub-contractors. We build not only for home owners but for developers, architects, draftsmen, real estate agents, government and local councils.

We specialise in difficult sites & unusual or unique 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.

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

The areas we service are the Hawkesbury, Hills District, Blue Mountains & the Sydney metro area

Whether you are building on the Northern Beaches, Leura in the Blue Mountains, Hornsby, Gosford, Parramatta or Epping OMara will service your area. 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 have a team of 16 full-time carpenters and 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.

Barry O'Mara originally started the company in 1964. Barry has received an OAM for his service to the building industry with his achievements including being a past President of the Master Builders Association of NSW, a retired Referee for the Department of Consumer Affairs, a Grade 1 Building Arbitrator, an Expert Witness for ICAC and the Supreme Court, just to name a few. His son Luke O'Mara now runs the daily operations of the company after completing a Bachelor of Applied Science (Building)  with Honours at the University of Technology, Sydney
