How long does a loft conversion take?

Typically, a loft conversion can take between **6 and 12 weeks**, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Hayle before agreeing to start the work.

Do I need planning permission for a loft conversion in Hayle?

Many loft conversions fall under **permitted development**, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Hayle loft conversion company can advise and handle permissions for you.

Landscaping- 16 Jun 2026
What can I say? Blown away. Ben led a landscape project for us involving a lot of concrete breaking, concreting, fencing etc, a lot of detail, materials, deliveries, juggling stuff. The comms, the effort, the finish, the professionalism and care were just the best I've ever experienced. Which is so important when you trust someone with extensive changes to your home. Huge huge thanks to Ben and his team for being flexible and making it happen. I wouldn't hesitate to recommend.
