Your design will be dictated considerably by your finances. While most people realise that they need to factor in the cost of the building work, it’s easy to forget about the other aspects that need to be accounted for on top of this.
Quite a lot of money has to be spent on things that seem minor on their own, but collectively can tot up to thousands of pounds.
Don’t forget to budget for:
finance and insurance costs
professional and local authority fees
access from the highway
The price of some elements can be fairly accurately predicted – such as planning fees and sewer connection charges – others have to be estimated.
