Just published a new blog on something I’m asked about all the time — where do you actually start when you’re thinking about an extension?

A Feasibility Study is usually the best first step. It lets you see what’s possible, what it might cost, and how the design could look before you commit to anything. Clients always say it gives them clarity and confidence, and that’s exactly why I offer it.

If you’re curious, you can read the guide here:

Just submitted a Planning Application for a home in Ballyholme, Bangor.
