Frequently asked questions
Do you need planning permission to extend upwards?
Adding a full storey usually needs planning permission, though some upward extensions and loft conversions fall under permitted development if they meet strict volume and height limits.

Is extending upwards cheaper than moving house?
For many families yes. Once you factor in stamp duty, estate agent and moving fees, extending upwards can be the more cost-effective way to gain space.
