Common Questions

Does a garage conversion need Building Control approval?

In most cases, yes, because it changes the use of the space to a habitable room. Our calculations cover the structural parts of the application.

Can the existing garage foundations take a new wall?

Sometimes. We check what's there, and if they can't, we design a new foundation for the infill wall.
