Our build cost calculator is a free tool that enables self-builders to get indicative figures for their build projects quickly and easily.

Labour and material prices are updated using an enterprise software platform who update rates and prices daily.

Within the build cost calculator, we include the cost of all construction materials and labour. You choose your superstructure , be it timber frame, ICF or any other type of construction, the floor areas and square meter size. We ask you to enter a budget for certain sections of your build project within the build cost calculator, such as kitchens and bathrooms.

You then get a total build cost output, along with a breakdown of each section of your build project, from the build cost calculator.

The prices quoted from the build cost calculator do not include VAT.

In the build cost calculator, we do not include the cost of any financing, insurance, professional fees, or connections to utilities.

All Mayflower clients get a detailed build cost and quantified schedule of works completed at no additional charge. Before then, feel free to use our build cost calculator above to get indicative project budgets. When you’re ready for detailed costs, we can do these from planning permission drawings only. All self-build mortgage lenders will require these detailed build costs at application.
