Loft conversions in Dorset

Dorset’s trusted loft conversion specialists – from first survey to final snagging.

Dorset’s trusted loft conversion specialists

If you’re looking for a loft conversion company in Dorset that has been doing this for a long time, and doing it well, World of Lofts is the right call.

We’ve been converting lofts for over 35 years, and we’ve built up 144 verified Checkatrade reviews with a 10/10 score. We cover Bournemouth, Poole, Christchurch, Wimborne, Ferndown and the whole of Dorset.

Every project is managed from first survey to final snagging by our own skilled team, not subcontractors. We handle planning applications, building regulations approval, structural calculations and the full build. You make one call; we take care of everything else.

Types of loft conversion we offer

The right type depends on your roof, your property and what you want from the space. These are the four we offer across Dorset.

Dormer

A box-shaped structure on the roof slope creates a vertical wall with a proper window. The most popular option in Dorset, adding headroom and floor space without dramatically changing the outside. Ideal for a double bedroom with en-suite, and most fall under permitted development.

Velux

The most straightforward and cost-effective route if your loft already has usable headroom. Velux windows sit flush with the roofline, bringing in light without changing the roof structure. Quick to build and usually within permitted development.

Mansard

One or both roof slopes are replaced with a near-vertical wall, greatly increasing floor area and headroom – often effectively a full extra storey. Usually needs planning permission, which we manage for you at no extra cost for the application management.

Hip-to-gable

Many Dorset semis and detached homes have a hipped roof. Replacing the sloping end with a vertical gable wall adds a lot of floor space, and it’s often combined with a rear dormer. Particularly popular in Bournemouth and Poole.

Planning permission in Dorset

Most loft conversions in Dorset don’t need planning permission – they fall under permitted development rights. We check with the right authority, whether that’s BCP Council (Bournemouth, Christchurch and Poole) or Dorset Council (the rest of the county), before any work begins. If permission is needed, we manage the full application. Read more about planning permission.

What our Dorset customers say

Highly recommended

“WOL came recommended from 2 of my close friends and I couldn’t be happier with the result. They’ve just finished our loft conversion in BH8 – 2 rooms and an ensuite – to a very high standard and reasonably priced. Sam and Dave (who run the show) are great – clearly priced the work, incredibly communicative throughout – leaving us picture on whatsapp at the end of every day with an update. The professionals they use are skilled, polite and a delight to have around the house while the work was ongoing. Highly recommended.”
