The space you already own

Many houses have a loft with enough height to convert. Done well, it is the cheapest square metre you can add to a house, and it does not cost you any garden.

A good loft conversion is mostly about the things you do not see: the steels and new floor joists that carry the room, the insulation that keeps it warm in January and cool in July, and a staircase that arrives on the landing without stealing a bedroom.

We handle all of it, including the structural design, fire safety, building control and the party wall process if you share a wall with a neighbour.

Not sure your loft is tall enough?

Measure from the top of the ceiling joists to the underside of the ridge. If it is around 2.2 metres or more, a conversion is usually possible. Or let Lewis measure it for you.

Wondering if your loft will convert?

Call Lewis or WhatsApp a few photos. He will tell you honestly what is involved and arrange a visit.

Loft conversion questions

Anything else, call Lewis on 07816 237961.

Does a loft conversion need planning permission?

Many dormer and rooflight conversions fall under permitted development, within limits on volume and position. Mansards, front dormers, and houses that are listed or in a conservation area normally need planning. Building regulations approval is always needed.

How long does a loft conversion take?

It depends on the type and the finish, and you get a programme with your quotation.

Will we have to move out?

Usually not. Most of the work happens in the roof and access is often from outside by scaffold until the staircase goes in.

What about the party wall?

If you share a wall with a neighbour, the Party Wall Act will usually apply. We will explain what notice is needed and when.

What our clients say

1860s house renovation★★★★★

Barlow Construction has helped me through a major renovation of an 1860s property, involving new suspended ceilings, new wall linings throughout, full damp proofing, new doors and lintels, a new central heating system, and new bathroom and kitchen installs. Lewis has been a pleasure to deal with throughout, and his advice and guidance have been invaluable. His onsite team show considerable depth of experience, with no dramas in dealing with the unexpected work that crops up in an old building. If only all firms were like this to deal with.

Single storey extension, patio and chimney★★★★★

We were introduced to Barlow Construction through our architect. They proved themselves to be a professional, trustworthy and reliable building company. Nothing was too much trouble. Originally taken on to do a single storey extension, which they did to an extremely high standard, we then asked them to lay a full surround patio with ACO drainage and repair our chimney stack. They were very tidy, clearing and putting everything away at the end of each day. We would wholeheartedly recommend them.

House extension★★★★★

Lewis and the team did a fantastic job on our extension from start to finish. Communication was excellent throughout, they kept us updated at every stage, turned up when they said they would, and left the site clean and tidy each day. The finish is exactly what we wanted and the whole process was far less stressful than we expected.

Refurbishment★★★★★

We recently used Barlow Construction for a refurbishment project and were extremely pleased with the service and the quality of work. Lewis was great to deal with from the start. Professional, reliable and always on hand to offer advice on the best approach and industry best practice. We wouldn't hesitate to recommend Lewis and the team.

Kitchen refurbishment★★★★★

The guys from Barlow Construction did an excellent job. They arrived on time. I was working from home throughout the kitchen refurbishment so got to know them. Great bunch of lads, great work. No issue too big or small, they got it sorted. Well pleased with the finish.

Ali D.via Google
Single storey extension★★★★★

Following a tender process organised by our architect, we chose Barlow Construction of Thirsk for a single storey extension enlarging our kitchen diner, and a raft of other internal work. Lewis and his team were exemplary. We particularly liked their flexibility with variations and extra tasks as we went along. Cleared up each evening and respectful of the property and neighbours. The standard of build and the communication throughout were superb.

Barn conversion, farmhouse and two extensions★★★★★

Lewis Barlow has been involved in two major projects at our house near Stillington. These included restoring a barn and converting it to residential use, renovating the original farmhouse, and building two substantial extensions. He has immense skill in all areas of construction, takes huge pride in his work, and is always a delight to deal with. He runs a team efficiently and explains what he is doing as he goes, always letting you know what the next day or week holds. Our house is a joy to live in.

Whole bungalow upgrade★★★★★

Every room has been upgraded in our extended bungalow by Barlow Construction. It took five months of continuous work and we can only describe it as faultless, not a word we use lightly. From day one their prime concern was to make sure we got what we wanted, with quality, politeness and excellent communication. Scrubbing the new patio on the last day summed up their whole attitude.

Alan S.via Yell
Single storey extension and kitchen★★★★★

We had a single storey extension and a new kitchen installed by Lewis and the team and couldn't be happier with the finished project. The work was of excellent quality and done with real professionalism and knowledge from start to finish. I cannot fault them.

Darran M.via Yell
Renovation★★★★★

After meeting Lewis we quickly realised we would be in safe hands, thanks to his approachable manner and well thought out programme of works. He and his team lived up to the high expectations they set themselves, and we have already pencilled in our next project. Punctual, polite, hard working and they left our home spotless after each working day.

Robert B.via Yell
Double storey extension★★★★★

Lewis and the guys built our double storey extension and fully completed the interior. From the en suite bathroom to the kitchen installation, Lewis project managed every area, which made it entirely stress free. The guys did an absolutely fantastic job and made our home look even better than we imagined.

House extension★★★★★

Lewis and the team did a brilliant job on our extension. Without them we would not have achieved our dream home. From basic drawings, a huge job was completed in record time to a very high standard, and Lewis always accommodated the changes we wanted. Our architect commented on the workmanship and took photos for his own website.

C & T P.via Previous website
Renovation★★★★★

Communication throughout the build was exemplary. It is a measure of Lewis's integrity that he will immediately flag unnecessary work that can be avoided, and he is happy to suggest alternative approaches, which were consistently better ideas than ours. The tradesmen he chose were professional, trustworthy and delivered without fault.
