Why did we create a free guide on home extensions for UK homeowners?

We’ve worked with thousands of homeowners across the UK, and we know the biggest stress isn’t always the build, it’s not knowing what comes next.

This guide is designed to remove that uncertainty. It’s the advice we give every new client, pulled into one easy-to-follow resource.

Guide and videos to help you plan with confidence

We know this might be your first extension. That’s why, alongside the guide, we’re releasing a step-by-step video series designed to help you navigate the process with confidence.

Each video builds on the last, breaking down key stages and offering practical tips to support your project from start to finish.

Free support for your home extension plans

At the back of the guide, you’ll find details of free tools and services we offer to help you move forward, like Q Spec (our quantity surveying service) and Design Spec Connect (our builder-matching service).

You’re under no obligation to use them, but they’re here if you need them.

Includes real home extension project examples

Get a look behind the scenes of a real Design Spec project, from first sketch to final sign-off. See how Sophie and Matt went from cramped kitchen to open-plan living space, all within budget.

We had £100k to spend. Their team designed to £95k. The builder’s quote came in at £97k. Couldn’t have asked for better.

— Sophie & Matt, Romford
