THE SELF BUILD ZONE
One of the most important aspects when planning your self-build or home renovation / extension project is working out how much it is going to cost.
Costs of your self-builds will depend on the size and shape of the house, the level of your own involvement, and where in the country you intend to build and the materials, fittings, and fixtures you’ re going to use.
If you can make even rough decisions about these factors, then you can begin to work out how much it is going to cost. As a very general rule of thumb, expect a building plot to cost between a third and a half of the end value of the finished house. The costs of building a house will then depend on the variables listed above.
All building work is usually quoted on a cost / m ² basis. For example, a typical new four-bedroom self-built home is around 268m ²( with 134m ² per storey) and usually varies between £ 2,250- 3,750 / m ²( although self-builders achieve costs ranging from £ 1,750- £ 10,000 / m ²).
Renovation costs are much more difficult to establish as they involve many variables based on the condition of the property, but a good starting point for an extension or major renovation is to allow £ 2,250 / m ² for work( plus VAT). This, added to the cost of the house and with a 10-30 per cent contingency, should result in less than the end value of the house.
