Frequently Asked Questions
Do I need planning permission for a loft conversion in Southampton?
Most loft conversions fall under permitted development and don't require planning permission, provided they meet certain size and design criteria. However, properties in conservation areas or those that have already used up permitted development rights may need approval. A loft specialist in Southampton can advise after seeing your property.
How much does a loft conversion cost?
Costs vary widely. A basic Velux conversion typically starts around £15,000–£20,000, while a full dormer can cost £30,000–£60,000 or more depending on size, specification, and location. Getting multiple quotes through Quote2 helps you benchmark the market in Southampton.
How long does a loft conversion take?
A typical loft conversion takes 6–12 weeks from start to finish. More complex projects — such as hip-to-gable or mansard conversions — may take longer. Your builder will provide a detailed programme once they've assessed your loft.
Will a loft conversion add value to my home?
Yes — a well-executed loft conversion typically adds 15–25% to a property's value in Hampshire. Adding a bedroom, in particular, can significantly increase the number of potential buyers and the sale price.
