WE BUILT IT OURSELVES

Building our extension, one decision at a time

We took on our own home extension without pretending to be professional builders. We learned as we went, watched a lot of YouTube, asked questions, made mistakes and gradually turned the plans into a finished part of our home.

This site is the record of how we did it: what it cost, what we tackled ourselves, what we paid trades to do, what went wrong and what we would do differently next time.

THE IDEA

A practical record, not a professional building manual

We want to show the decisions behind the finished extension as well as the finished rooms: quotes, materials, sequencing, unexpected problems, DIY jobs and the parts that were harder than they looked.

Where something worked well, we will explain why. Where we got something wrong, we will include that too.

FOLLOW THE BUILD

From first plans to finished extension

The site will grow around the actual stages of our project rather than generic home-improvement advice.

LEARNING AS WE WENT

The bits that rarely appear in the finished photographs

A finished extension can make the whole process look much simpler than it was. We want to include the messy middle as well: changing decisions, comparing quotes, trying jobs for the first time, finding information online and working out when it made more sense to bring in someone experienced.

Our extension

Start with the overall project: what we wanted to change, why we decided to extend, how we approached the work and how the house evolved through the build.
