It is also very important that you work out all the costs that will occur during your project before you start, including all the contracts, materials, insurance, and so on plus an extra 20% for unexpected costs.
Make sure that you have decided on exactly what you want in your project and have agreed them with your contractor or supplier as any changes during the project would probably cost you a lot more.
One very important factor on cost saving would be your initial design of the house. The following are just some guides:
If you want a lot of space at a lower cost, go for a two storey house instead of a bungalow as a bungalow have a much larger foundation area and roof coverage than a house. For example, on a house all the rooms upstairs share the same foundation and roof as the space downstairs, but if you were to gain the same space on a bungalow you would have to double the foundation and roof area.
When you are designing your walls do remember that blocklayers charge you a lot more for a projects that has a lot of different levels and angels as this makes their job a lot harder and takes more time, so if you can keep it simple.
When designing the roof, do remember the more angles and gables means more material, more time and cost. again if you can keep it simple.
Think about the heating and waste system, many options are cheap at the beginning but will cost you more over the long term. Go to Renewable Energyand Waste Management .
In order to avoid any unexpected problems in your project make sure that you have full understanding with all your contractors, suppliers and other professional’s you are dealing with as far as time schedule and cost involved before you start the project.
