Permitted development rules let homeowners extend their homes without full planning permission—provided certain conditions are met. We’ve delivered hundreds of projects within these guidelines, creating great designs that meet local council requirements.

In many cases, our clients can go straight into construction without waiting for formal approval, helping the project move forward without delays.
