A loft conversion is the most cost-effective way to add a bedroom, en-suite or office. The structure is already there, so you gain a whole floor for around half the cost per square metre of an extension.
We build rooflight, dormer and hip-to-gable loft conversions across Dorset, managing structure, building regs and the staircase throughout.
Every certificate we hold is one you can check yourself. We’ll hand you the paperwork at completion without being asked.
“Every member of the Thicketts team was meticulous, professional and a pleasure to work with. They turned our vision into something truly special.”

Size up your loft
Pop your head through the hatch and note the rough floor area, and whether you can stand up in the middle. That’s all we need.
Pick your conversion
Rooflight, dormer, hip-to-gable or mansard, plus how many rooms you want up there. The price updates instantly as you plan.
Let’s get started
Either our team will call you back to discuss the details or a surveyor will pay you a visit - you choose!
Every detail, done properly.
From the oak handrail to the push-latch eaves storage, your loft is finished to the same standard as the rest of the house: insulated, certified and ready to sleep in.
You stay living at home.
Because almost all the work happens from outside via scaffolding, most families carry on as normal throughout the build. We only break through for the staircase near the end, so no months of living on a building site.
What’s included?
One team takes your loft from survey to signed-off rooms, with no gaps between trades and no paperwork left to you. Every conversion includes:
A whole new floor to play with
From a master suite to a quiet office, here’s what our customers do with the space up top.

Kids’ bedrooms
Free up the floors below as the family grows.
Home office
The quietest room in the house, up out of the way.

Teen den

See what’s coveredReasons to build with us
We’re a small Dorset team who care more about doing it right than doing it fast. Here’s what that means for you.
Get an instant priceThe cheapest room you’ll ever add
The structure is already there, so a loft conversion typically costs half what an extension does per square metre, and adds more to your valuation.
Instant, realistic pricing
No “book a free design consultation”. Tell us your loft online and see a genuine figure up front, confirmed at survey and fixed from then on.
We live outside until the last week
Scaffolding and a roof opening mean almost everything happens from outside. Most families keep every room in use until the staircase goes in.
Building regs handled for you
Structural calculations, fire regs, insulation and staircase compliance are all managed and certified by us. You get the completion certificate for your file.
Warm, safe & signed off.
Every conversion is fully insulated, fire-regs compliant and finished to the same standard as the rest of your home. We manage the structural design and building control, and hand you the completion certificate for your file.

Most Dorset roofs have a spare room hiding in them. It costs less than moving and adds more than almost anything else.
