Self build costings

If you find yourself wondering “How much does a self-build home cost?”, you’re not alone. It’s one of the most common questions we get asked. The answer is that it depends on multiple factors around three main areas; the plot, the design and the specification.

Don’t be put off by thinking that a self-build project is too expensive - we cater to a wide range of budgets and offer a fixed fee approach. There’s no nasty hidden surprises. The question, really, should be, “What can CB Homes do for me with my budget?”

We have over 35 years of experience of working closely with our clients to understand their exacting requirements, we offer comprehensive flexibility to work towards any budget and from the onset offer a fixed fee.

We’ve developed a handy cost calculator to give you an idea of a budget cost you can expect with a self-build home.
