Build It Estimating Service

The Build It Estimating Service, powered by HBXL, helps self-builders turn their house plans into an accurate, detailed estimate — down to the last roof tile. Whether you’re planning an extension or a full new build, our service provides clear, practical, and self-builder-friendly information to guide your project from start to finish.

For just £249 for an extension and £299 for a new build, you’ll receive a comprehensive estimate report including live material costs from leading builders’ merchants, detailed labour costs, a cash flow forecast, and the ability to adjust and customise figures to suit your budget. Every report is designed to give you a realistic picture of your build costs, helping you plan with confidence.

At the show, you can book an appointment with a qualified, experienced estimator who will guide you through your estimate and explain how to make the most of the report. Don’t forget to ask about our new Benchmark report, which provides accurate headline figures for your build, helping you quickly understand the broad outline of your project and your options.

With the Build It Estimating Service, self-builders gain the insight and clarity they need to make informed decisions — turning your dream home from concept to reality with confidence and control.
