Frequently Asked Questions
Do I need planning permission?
Most conservatories fall under permitted development if they meet size limits and don't cover more than half the garden area.
Is a conservatory or extension better value?
Conservatories cost 30-50% less than brick extensions per sqm. However, extensions add more value per pound spent and are more versatile.
