TrueBuild Loft Conversions turns unused roof space in Leeds homes into bedrooms, ensuites and extra living space. We build dormer, rooflight (Velux), hip-to-gable and mansard conversions, design and fit new loft staircases, and rebuild existing lofts that were never done properly.
The same small team handles the strip-out, structure, carpentry, building work, electrics, plastering and finishing, so you aren’t juggling trades. Customers mention the same things again and again: they turn up, they keep you updated, and they leave the house tidy.
The right type depends on your roof shape, head height and how much space you want. Shaded areas show the new room each one creates.
A box-shaped extension built out from the rear roof slope, turning sloping ceiling into full-height walls and floor space. The most popular choice for Leeds terraces and semis.
Good fit: Terraces and semis, bedroom plus ensuite
More about dormer loftsThe roof shape stays as it is. We strengthen the floor, insulate, and fit rooflights into the slope to flood the room with light.
Good fit: Lofts that already have good head height
More about rooflight loftsThe sloping side of a hipped roof is built up into a vertical gable wall, making room for a staircase and a much bigger loft. Often combined with a rear dormer.
Good fit: Semis and detached houses with a hipped roof
More about hip-to-gable loftsThe rear roof slope is rebuilt at a near-vertical angle with a flat top, giving the most usable space of any loft conversion.
Good fit: Maximum space, usually with planning permission
More about mansard loftsA loft is only as good as the staircase up to it and the finish inside it. These are built in from the start, not bolted on at the end.
Designed to fit tight landings, with spindles, handrail and balustrade.
Shower rooms planned into the conversion, tiled and finished properly.
French doors and frameless glass that open the room to the view.
Tired or badly built lofts stripped out and rebuilt to feel like part of the house.
Word for word, from families who’ve had their lofts done by Mark and the team.
We had our loft conversion done by TrueBuild Loft Conversions in spring 2025. We had tried a few other local companies first but some wouldnt even come out to give us a quote so we contacted TrueBuild after being recommended by a friend.
Mark was helpful from the first phone call and came out the next day to have a look and give us a quote. We decided to go ahead with them and really glad we did.
Everyone who worked on the house was friendly polite and respectful which was a big thing for us as we have 2 young children and the house was basically a building site for a few months.
Everything went to the timescale Mark had given us and the price was what we had agreed at the start, no random extras suddenly getting added on halfway through. The work was all done to a really high standard and you could tell they werent cutting corners.
The loft has completely changed the house and looks exactly how we wanted it. Really happy with the end result and would definitely use TrueBuild Loft Conversions again.
If your wanting a loft conversion done properly by a team who actually turn up, respect your house and do a good job then id definitely recommend them.
Had our loft conversion done by TrueBuild Loft Conversions with a dormer and ensuite and honestly couldnt be happier with how its turned out.
From the start Mark was really helpful and explained everything to us properly, kept us updated and made the whole job feel a lot less stressful than we thought it would be.
Big thank you to Shane and Brad aswell who worked hard every day, always turned up on time and were respectful of the house. Plenty of coffees biscuits and the odd breakfast butty kept them going 😂 the finish on the dormer and ensuite is brilliant and you can tell they take pride in what they do.
Also want to mention Josh who was polite and worked hard throughout, a credit to the team.
Its completely changed the house for us and given us loads more space. Everyone was friendly tidy and reliable from start to finish.
Would definitely recommend TrueBuild Loft Conversions to anyone thinking about getting their loft done and we would use them again for future work without a doubt. Thanks again lads 😊
TrueBuild Loft Conversions completed some work for us in January 2026 and we couldn’t recommend them highly enough. We bought a house with an existing loft conversion, but the staircase was extremely awkward and unsafe to use. We honestly didn’t think there would be enough space to install a proper full-sized staircase.
The team came out, measured everything up and designed a new staircase complete with spindles, handrail and balustrade. The difference it has made is incredible and it has completely transformed the loft space while adding real value to the house.
Everyone involved was punctual, professional and very tidy throughout the job. The electrics were moved where needed and all the plastering was finished to a really high standard.
We would definitely use TrueBuild Loft Conversions again and would happily recommend them to anyone needing loft conversion or staircase work. Apologies for the delayed review we’ve been busy renovating the rest of the house!
Choosing TrueBuild Loft Conversions for our loft was definitely the right decision. From the first time we spoke to Mark everything was easy and straight forward and he was always helpful.
Mark and the lads were a brilliant team, Shane Brad and Josh all worked really well together and you could tell they knew what they were doing. From ripping out the old loft to the carpentry and building work everything was done really well and the attention to detail was spot on.
We changed our mind on a couple of things last minute aswell and they were always happy to help and never made it feel like a problem.
We stayed living in the house while the work was being done and honestly it wasnt anywhere near as bad as we expected. They cleaned up every day and always respected the house which made a massive difference.
You can tell they actually care about the work they do and wanted to make sure everything was how we wanted it. Really happy with how its all turned out and feel lucky we found them. Would definitely recommend TrueBuild Loft Conversions.
Excellent communication from start to finish and really happy with the work from Mark and the team. Hardly any disruption while the job was being done and Mark went out of his way to make sure everything ran smoothly.
Absolute pleasure to deal with and couldnt rate TrueBuild Loft Conversions highly enough. Thanks again lads!
Loft conversions mean builders in your home for weeks. These are the things that make that easy, in our customers’ own words.
Customers say the same thing: the team arrives when they said they would, so you’re not left wondering whether anyone’s coming today.
always turned up on time and were respectful of the house
Your house is still your home. The work area is cleaned up at the end of each day and the rest of the house is respected.
They cleaned up every day and always respected the house
Your quote is based on a proper look at your loft, so there’s far less room for nasty surprises later.
the price was what we had agreed at the start, no random extras suddenly getting added on halfway through
Seen a tile you prefer or want a socket moved? Tell us. Plans can change as the room takes shape.
We changed our mind on a couple of things last minute aswell and they were always happy to help
Mark is your point of contact from the first call and keeps you updated through every stage.
explained everything to us properly, kept us updated
Most of the work happens in the roof, so families stay put while the loft is built.
We stayed living in the house while the work was being done and honestly it wasnt anywhere near as bad as we expected.
Six stages from first phone call to finished room. You’ll know where you are at each one.
Tell us about your house and what you’d like the loft to become. A bedroom, a suite with an ensuite, an office, or a fix for a loft that isn’t working.
Mark comes out, measures up, checks head height, roof structure and where a staircase can go, then talks you through the options and gives you a price.
We agree the layout, windows and finish, and talk you through planning permission, Building Regulations and any party wall notices your house needs.
The loft is cleared, the floor and roof structure are built, and dormers or gable walls go up with the roof made watertight.
Electrics, plumbing for any ensuite, insulation and plasterboard go in, then everything is plastered ready for decoration.
The new staircase goes in, joinery and ensuite are finished, and the house is cleaned up and handed back to you.
A small team you’ll get to know by name, and who customers mention by name in their reviews.

The short version of the rules for loft conversions in Leeds, and in England generally.
Many loft conversions count as permitted development and don’t need a planning application, provided they:
Flats, maisonettes and houses in conservation areas usually need permission.
Always required when a loft becomes a habitable room. Approval covers:
Keep the completion certificate. Buyers’ solicitors will ask for it.
If you live in a semi or terrace and the work affects a shared wall, for example cutting in steel beams, the Party Wall etc. Act 1996 means your neighbours need written notice before work starts.
It’s a routine step for most loft conversions and we’ll flag it early so it doesn’t hold up your start date.
This is general guidance for houses in England, not legal advice. Every house is different, so we’ll go through what applies to yours at the home visit. You can also check with Leeds City Council’s planning service or apply for a Lawful Development Certificate for extra peace of mind.
Can’t see yours? Call 0113 490 0744 and ask Mark.
It depends on the type of conversion, the size and shape of your roof, where the staircase can go and whether you want an ensuite, Juliet balcony or other extras. Rather than quote a figure that might not fit your house, we come out, measure up and give you a price for your loft.
Call 0113 490 0744 or send the form and we’ll arrange a visit.
Many loft conversions in England fall under permitted development, so they don’t need a full planning application. The allowance for extra roof space is 40 cubic metres for terraced houses and 50 cubic metres for semi-detached and detached houses, and the work must not extend beyond the front roof slope facing the road.
Permitted development doesn’t apply to flats and maisonettes, and roof extensions in conservation areas usually need planning permission. We’ll talk you through which applies to your house when we visit.
Yes. Turning a loft into a habitable room always needs Building Regulations approval, whether or not planning permission is needed. It covers the floor and roof structure, a safe staircase, fire safety and escape, insulation and sound. You’ll want the completion certificate when you come to sell.
It depends on the type and size of the conversion and how much finishing work is involved, such as an ensuite. You’ll get a timescale with your quote. One family told us: “Everything went to the timescale Mark had given us”.
Yes. Customers have stayed at home throughout. Most of the early work happens up in the roof, and the team cleans up every day. One customer said: “We stayed living in the house while the work was being done and honestly it wasnt anywhere near as bad as we expected.”
As a rough guide, measure from the top of the ceiling joists to the underside of the ridge. Around 2.2 metres or more at the highest point is usually a good sign. Roof pitch, the type of roof structure and where a staircase can land all matter too.
If you’re not sure, that’s exactly what the home visit is for.
Terraced and semi-detached houses often suit a rear dormer, which adds the most usable floor space. Semis and detached houses with a hipped roof often suit a hip-to-gable conversion. If your roof already has good head height, a rooflight (Velux) conversion keeps the roof shape and is usually the least disruptive. A mansard gives the most space but more often needs planning permission.
Yes. We design and fit new loft staircases, including spindles, handrail and balustrade, and can move electrics and replaster around them. One customer with an existing loft said they “didn’t think there would be enough space to install a proper full-sized staircase” before we measured up and designed a new one.
Yes. Loft ensuites are one of the most popular additions. A dormer often gives the head height a shower needs, and we plan the layout, tiling and finish as part of the conversion.
Yes. If you’ve bought a house with a dated or badly built loft, we can strip it out, rebuild and refinish it, or just replace the parts that aren’t working, like the staircase.
We cover Leeds and the surrounding areas, including Headingley, Roundhay, Chapel Allerton, Horsforth, Moortown, Alwoodley, Kirkstall, Pudsey, Morley, Rothwell, Garforth, Otley and Wetherby. If you’re close by and not listed, give us a ring.
