Why Should I Choose
BNS Loft Conversion Specialists

Have you had much experience with building companies in London? We have, and unfortunately, good customer service alongside high-quality work doesn’t seem to be high on the list of priorities.

It’s harsh, but it’s also true. And the thing is, this is your home we’re talking about. It’s not changing tires on your car or your monthly TV package – your home is the biggest and most important purchase you’ll ever make. Your pride and joy; your sanctuary that you’ve spent your life savings on; somewhere you can relax, unwind and create amazing memories with your friends and family.

So it has to be perfect, with absolutely zero exceptions to that rule.

That’s why we created BNS lofts, which is backed by the reputable BNS Construction LTD – a trusted building company who’ve been completing high quality work in the building industry for a long time.

Types of Loft Conversions

The BNS Loft team understands that no two loft conversions are truly the same; not only because of the diverse selection of properties available but also because of the wonderful variety of people, tastes and lifestyles. We work hard to tailor every loft conversion project to the needs of the client and include everything they might need.


Dormer lofts are one of the most popular types of loft conversion, and it’s easy to see why. They can be used for almost anything – an extra bedroom, a home.

Hip to Gable

Another popular route for people looking to add space to their home with a loft conversion is the Hip to Gable loft conversion. Let’s take a look at

Hip To Gable And Rear Dormer
Loft (Combined)

The name is a slight giveaway – this is where hip to gable and rear dormer lofts are combined. You’re essentially integrating two different types of loft

L-Shaped Dormer Loft

Also known as ‘dog leg conversions,’ L-shaped dormers are very similar to their cousins, the standard dormer. The major difference is that with an L-shaped


Fun fact – Mansard loft conversions are named after the 17th century French architect Francois Mansard. Now we’ve got that one out of the way, let’s have

Skylight/velux loft conversions are one of the most affordable conversions you can add to your home, so it’s no wonder so many people are taking advantage

Ben and Sophie have been extremely helpful and professional throughout the project and they have responded to all my queries swiftly and clearly right from the beginning. My project is mainly to convert a one-bedroom flat into a two-bedroom flat with an open kitchen and carry out renovation work within a block of flats. There were concerns about possible nuisance to my neighbours but the team had always tried their best to minimise disturbance and disruption to my neighbours as well as address their concerns as far as practicable. The workmanship and work completed by BNS are of high quality and have in many aspects exceeded my expectations. On several occasions when there were changes to the original design, Ben and his team have patiently and effectively accommodated my requests and have been very polite and reasonable in every occasion. Furthermore, Ben had arranged the team to kindly reskim the entire property out of courtesy, which was not part of the original agreed scope of work, simply because Ben wanted me to enjoy an immaculate flat when finished! This shows that Ben will try his very best to come up with a high standard of work and ensure complete satisfaction of his customer. Though the work period was longer than originally envisaged due to unprecedented issues, the problems were resolved smoothly and quickly by the team. I was kept up to date on the work and progress all the time which I really appreciate. It has been a pleasure working with Ben, Sophie and the team, and I am both thankful and grateful for all their kind assistance, helpful advice and professionalism throughout the past few months. I have no hesitation to recommend BNS Construction Ltd to my friends and colleagues should they look for an honest, responsible, competent and quality builder.

We’ve used Ben and the team for multiple projects such as an extension, bathroom refurbishment, rewiring and plumbing. Bens team are so polite and such hard workers. I couldn’t fault the service at all. Were so happy with the end results !

Ben and his team did a fabulous job on a 6 x 5 meter extension with a lantern ceiling. The boys tidied up very well every day and nothing was too much trouble. Would highly recommend.

Ben and his team are courteous, professional and very easy to talk to. It started with an extension for a granny flat and grew into half the house being renovated. There were a few mistakes on both sides as things changed but Ben was always available to talk to and nothing was ever a problem to sort out. He works to a high standard and leaves the place clean and tidy. I would be more than happy to use him again and have already recommended them to friends

We had a very positive, overall experience with the lovely Ben and Sophie who run a tight ship at BNS Construction and happily recommend you consider meeting them before committing to your next project. Having shopped around for a few months, from the day we first met Ben and Sophie it was clear that they are a very sincere and genuine couple who strive to provide a high value service through their personal and friendly approach towards their clients and operations. Our ground floor, rear extension and WC conversion wasn’t a large project but still required an element of diligence and care which Ben and Sophie strived to provide, through their team, from day one. As with any similar scope of project some challenges occurred but Ben and Sophie constantly and consistently stepped up and rectified matters, where they were required. Ben and the team were excellent at staying flexible and working around all of the (inevitable) obstacles that occur during these builds, however, none of these were too big to overcome and Ben was always on hand to listen and provide his assurances and expertise… sometimes working late into the night but always with a smile on his face. We're delighted with how our extension / conversion has turned out!

We used BNS to reconfigure our bathroom and remove an upstairs chimney breast. The work was completed efficiently and to a good standard! The plastering was very good indeed and the project management excellent. Very responsive and would certainly use again and recommend to others!

The BNS team have been brilliant! Ben and Sophie were incredibly professional, constantly checking in to make sure everything ran smoothly with the project. Whilst Miri and the guys did an incredible job of our house renovations including fitting the kitchen island, building a recessed wall, panelling and putting in bi-folding doors into our office. They always kept everything as clean as possible and everything has been done to an incredibly high standard. I cannot recommend them enough and am very pleased with how the works turned out.

Highly recommended construction company. I asked for a full refurb and double extension and roof conversions to be carried out. I am so happy with the overall finish of the project. Ben kept me up to date at all times through our group chat and always answered my questions promptly. His team were professional and respectful at all times and I would recommend BNS construction to anyone looking for a high standard of finish and a reliable builder.

Updated my previous review now that the project has been finished. I came across BNS Ltd from a family recommendation and used Ben & Sophie to do a 4m extension, covered patio, new rear shed and ground floor renovation including removal of chimney breast, new toilet and pantry. Although I was worried at times, Ben always put my mind at ease with his can do attitude. There hasn't been any hidden costs, the work was done very professionally and even complicated items (such as some drainage alternations in the neighbours) was done with minimal hassle. The project finished on time even with additional items added to the scope of works (we wanted a bigger patio and some shelfing in the pantry etc) Ben & Sophie balances a few projects at the same time but they are always available via the phone when required so you feel cared for in terms of the personal support and experience. Sophie is helpful giving us their best suppliers which get good rates and discounts and help with the timing. We lived in the property during the entirety of the works and the team ensured they always tidied up at the end of the day as well as made sure we never lost hot water in the midst of swapping kitchens and boilers. Even after the works Ben was always willing to pick up the phone or come see if we wern't sure about anything which shows a care beyond just the completion of works. Everything went smoothly and would highly recommend Ben and Sophie and their team and we are certainly enjoying our new extension.

BNS Construction renovated my entire property; 2 reception rooms, kitchen, dining room, 4 bedrooms and 2 bathrooms. The team were absolutely fantastic from start to finish, they listened to all my ideas and gave me lots of helpful suggestions. Ben explained all the costs in his estimate and even sourced helpful cost effective alternatives to save me money. I am so pleased with the finish and workmanship. I will be recommending them to all my friends and family. I am planning to have an extension in the future and will be using BNS again, without a doubt!
