Loft conversion by The Big Conversion Company

Loft Conversions in Poole

Turn your unused loft into a bedroom, en-suite or home office — without moving away from the town you love.

Loft conversions for Poole homes

At The Big Conversion Company we design and build loft conversions across Poole — from Broadstone and Creekmoor to Parkstone, Oakdale, Canford Heath and Hamworthy. A loft conversion is one of the most effective ways to add living space and value to your Poole home, whether you need an extra bedroom, an en-suite, or a dedicated office now that more of us work from home.

Poole's housing stock suits conversion unusually well. The town's interwar and post-war family houses generally have accessible roof spaces, and the bungalows common around Broadstone, Merley and Canford Heath are classic candidates for dormer and hip-to-gable conversions that can transform a two-bedroom property into a family home.

Which loft conversion suits your property?

Velux (rooflight) conversions

The most cost-effective option where your loft already has good head height. The roofline stays untouched, which keeps cost and build time down.

Dormer conversions

A box dormer adds head room and genuine floor space, and suits most of Poole's semi-detached and terraced homes. The most popular balance of cost and gain.

Hip-to-gable & complex builds

For bungalows and hipped-roof properties, the hip is built up into a gable, usually paired with a rear dormer for the largest possible new floor.

The case for it

Why convert your loft?

Moving house isn't always the best option. A loft conversion allows you to maximise the space you already have — and we'll tell you honestly during a free site visit whether yours is suitable. Head height, roof structure and where the new staircase can land all matter.

Perfect for

  • Additional bedrooms
  • En-suite bathrooms
  • Home offices
  • Guest rooms
  • Add value to your home
  • Avoid moving costs
  • Make better use of unused space
  • Stay in the area you love

Honest pricing

What a loft conversion costs in Poole

Cost depends on the structure, size and finish: rooflight conversions sit at the lower end, dormers in the middle, and hip-to-gable or structurally complex builds at the top.
