This project is now fully completed, and I’m delighted with how the new extension and redesigned ground‑floor layout have transformed the home. The additional space has made a significant difference to how the rooms connect and function, and it’s rewarding to see the design come together so successfully on site.
I was also pleased to receive a 5‑star review from the homeowners:
“Glenn was responsible for the drawings for our kitchen extension and the redesign of our downstairs layout, which has just been completed. We are very pleased with the final result. Every detail has been meticulously considered, greatly improving our use of the space. He also handled all the administrative tasks associated with submitting the drawings for planning approval, which was immensely helpful. I would highly recommend his services.”

Orby Drive, Belfast
Rear Extension & Open‑Plan Living
My clients wanted to stay in their home rather than move, but their existing layout simply wasn’t meeting their needs. With superb views over their large gardens towards Greenville Park, it was clear why — the best outlook was only available from a small patio.

A new downstairs WC and a Study were also added as part of the redesign. The difference this extension has made is remarkable — a wonderful, improved home that now makes the most of its setting.
