Cost Of Construction

Owning a house is the biggest investment that most of us make in our lives, so we need to make sure that before we leap into the construction of our dream home we have some sort of idea about how much our project will cost to complete.

The following is only a guide to help you work out an approximate cost of your project and do remember that every project is different in the type of construction, route of construction, the material used and the quality required.

The figures below show the approximate percentage of the total cost of a new home through each stage of the build. This is based on an average detached home on two floors.

What are the approximate costs?

Site Clearance  3% Foundation  9% External Walls 17% Roof  9% Windows and External Doors  7% Upper Floor 2% Stairs 1% Internal Walls 2.5% Internal Doors 2.5% Floor Finishes 4% Wall Finishes 5% Ceiling Finishes 2% Heating 6% Electrical Installation 4% Water Installation (Cold/Warm) 2% Waste & Sanitary 7% Kitchen 5% Built In Cupboards 1% Professional Fees 11%

For the purpose of this exercise we will concentrate on a concrete home and direct route.

Do remember the above calculations are only approximate and every project would have its own procedures.

For example, some builders would do the floor in two sections a sub floor and then the top layer and so on.

The above is only a guide to give you some idea’s in the cost involved. You should always add 20% extra for other and unexpected items.

In order to get an accurate cost of your project, you can use a quantity surveyor to do a cost plan for you.
