What will yourbespoke home actually cost?
Five questions, benchmarked against real recent builds across Hertfordshire, Buckinghamshire, Bedfordshire and North London. Free, instant, and no obligation.
An honest starting number
Before you commit to anything
Bespoke builds routinely run six figures over the original estimate, because the original estimate was never built from a real cost plan. This gives you a defensible range in under a minute.
It is a starting point, not a quotation. The number that matters is produced in the Feasibility Study, once we understand your site properly.

FAQs
About the calculator
It is an indicative range, not a quotation. It is benchmarked against recent bespoke projects across Hertfordshire, Buckinghamshire, Bedfordshire and North London, but your actual figure depends on site conditions, ground works, structural design and specification. The Feasibility Study is where a real number is produced.
