Home extensions under permitted development

Need extra space but don’t want to undergo the 8-10 week planning process? A simple, straight-forward home extension under permitted development can help create the kitchen you’ve always wanted, a dining room the whole family can fit into at Christmas, or even a quiet snug to escape it all. Use the diagrams below to see whether your project fits within permitted development rights, how much space you can achieve without planning permission and how much our design packages cost.
