BUILDING DESIGN
DUPLEX'S
OMara has now a great standard design for a duplex that will suit most sites. We also have a large data base or previous projects to draw from and a specialist duplex building designer that can design your proposed duplex to suit the local council requirements, owner needs and site specific conditions.
2ND STOREY ADDITIONS
OMara has completed many 2nd storey additions. We can show you how to make your existing design more economical or the best way to design a 2nd storey addition that will create the least amount of disruption to the owners, without moving out during construction, look like it was always intended to be a 2 storey addition and not look like a "box on a box"
HOME EXTENSIONS / RENOVATIONS
There is probably not a type of home extension in our 46 years that we have not completed. We can offer advise on how to have your home extension completed to budget and add value to your home. We see every day poorly designed home extensions & renovations that with a few changes can become the home you always dreamed of.
NEW HOMES
We have built single storey, 2 storey, 3 storey, 4 storey homes, timber floor, concrete slab, suspended slab, full brick, stone, copper roof, timber pole, flood affected, difficult site, high risk bushfire, remote location homes since 1964. If it can be designed, then we can built it ! More importantly we have the contacts to select the correct building designer that can prepare a practical design to your budget that will be a "home", not just a house
FACTORIES
If you select the wrong engineer when building factories it won't cost you $1,000's it will cost you $10,000's. Although factories seem simple to design if you select the incorrect methods of construction structural steel and concrete prices will sky rocket. You do not have to be a builder to build factories so the industrial building industry if full of part-time unlicensed contractors that are keen to offer poor advise. Be aware if you make a wrong decision in selecting a factory building designer there are huge consequences. OMara can put you in contact with the right people in this area. We were building factories before tilt-up concrete construction was even invented.
MULTI-UNIT DEVELOPMENTS
There is so much to learn in this area it is impossible to write down in simple terms. Everyone thinks they can make a fortune but there are so many hidden costs and specific council requirements that unless you know what you are doing there will be little doubt of losing money. If you intend on designing & constructing a multi-unit development then you need to know the right people to talk to. OMara has the contacts and the experience
BUILDING DESIGNERS
So no matter what the building project is OMara has the contacts to put you in touch with the right professional to suit the project. OMara can then consult with the designer to ensure the project is designed within the owners budget and incorporates the most suitable and economical construction methods.

CONSTRUCTION COSTS

The following is a basic guide for construction costs for various projects including new homes, additions / extensions or renovations and commercial or industrial projects.

The most accurate way is to have a concept plan prepared but hopefully the following rates give potential clients a rough guide of building costs;
 
AREA
