How much does a dormer loft conversion cost?

A dormer loft conversion typically costs between £40,000 and £55,000, depending on the size, specifications, and finish quality. This includes structural work, insulation, windows, flooring, electrics, and plastering.

Do I need planning permission for a dormer loft conversion?

Most dormer loft conversions in the UK fall under permitted development rights and don't require planning permission. However, you'll still need Building Regulations approval. Check with your local council if you're in a conservation area or listed building.

How long does a dormer loft conversion take?

A typical dormer loft conversion takes 6-8 weeks to complete, from initial construction to final finishing. This timeline can vary based on the size of the project and any custom requirements.

Will a dormer conversion add value to my property?

Yes, a well-executed dormer loft conversion can add 15-20% to your property value, typically £20,000-£40,000 in most areas. It also creates valuable additional living space.

Can I live in my house during the dormer conversion?

Yes, most homeowners stay in their Brighton & Hove properties during dormer conversions. The main work happens in the loft space, though you'll need to accommodate the staircase installation. We minimize disruption wherever possible.

What's the difference between a dormer and a Velux conversion?

A Velux conversion installs windows into the existing roof slope without changing the roofline, while a dormer extends upward creating a box structure. Dormers provide significantly more headroom and usable floor space but cost more than Velux conversions.

Do dormer conversions need to match the existing house style?

While dormers should complement your home's architecture, exact matching isn't always required, especially for rear elevations. Our designers ensure your dormer integrates aesthetically while maximizing internal space.

How do you insulate a dormer loft conversion?

We use high-performance insulation meeting current Building Regulations (minimum 270mm in roof spaces). This includes insulated plasterboard, mineral wool, or spray foam insulation to ensure excellent thermal performance and reduced energy bills.
