How much can you expect to pay?
Adding an extension is probably an easier and cheaper option than moving, even so, it’s difficult to know how much that extra space will cost.
Typically, the larger the extension, the cheaper it will be, thanks to economies of scale.
By using the bullet points below you can make sure you’ve covered everything, so when you receive a quote you’ll know what to look for.
Depending on the nature of your project, you may have to pay for some or all of the following:
- An architect’s services
- Planning permission
- Building Regulations approval
- Arranging a loan or re-mortgaging
- The services of a surveyor and/or structural engineer
- Exploratory excavations
- Land clearance
