self build calculator

A simple self build cost calculator to help you estimate your self build cost. These figures have been updated in 2022 following recent price increases in construction costs, according to a survey of architects and designers on Design for Me.

Self build cost calculator 2022

The above calculator is based on estimates as a starting price for a self build house. Above costs assume modest finishes, fittings, electrics and lighting.


Kitchen cost

We have allowed £10,000 for a kitchen. This should allow for a basic, average sized kitchen with basic appliances. You can add extra to the total as you require for your specification.


Bathroom cost

We have allowed £10,000 for a WC/bathroom.


Professional fees

We have allowed 15% on the construction costs for professional fees.



VAT has not been included, as the majority of construction/material costs are zero rated for VAT.


Case studies – self build costs

We asked the architects on Design for Me for real-life examples of self build houses and how much they cost. See our article here.
