Love where you live. Just wish there was more of it?

Plan Your Extension

Beautiful homes. More space. Expertly built.

The problem

Your home shouldn't dictate how you live.

A home that once felt generous can quietly become too small. Kitchens grow cramped, the dining table doubles as a desk, and the layout that worked for two no longer works for four.

Children need more room. Another bedroom would make all the difference. Working from home demands a space of its own. And the way your family lives today simply doesn't fit the home you moved into years ago.

Moving isn't always the answer. The home you already love may have the potential to give you everything you need — you just need to unlock it.

03

04

06

Finishing & Handover

Complete agreed finishing work and final checks before handing over the new space.

Imagine

Imagine what you could do with a little more room.

  • Sunday mornings around a kitchen island
  • A bedroom where there used to be a dusty loft
  • A home office with a door that closes
  • Space for children to play
  • Summer evenings flowing from kitchen to garden

Your home may already have the potential to give you all of it. You just need to unlock it.

Do I need planning permission for a porch?

Many porches fall under Permitted Development if they're under three square metres, below a certain height and more than two metres from a boundary facing a highway. Larger or more prominent porches may need permission. We'll advise on your specific case.
