Hired Craftex for our conversion project. We had to convert a 600m2 office into 8 apartments. Guys did an excellent job in terms of program efficiency and quality of the finishes which gave us a big upside to exit the project 2 months faster than other competitors’ timelines.

I’d like to thank the team at Сraftex for the work they did on our office.
It was really important for us to get the work done quickly, but without compromising on quality, as we regularly have clients and guests visiting and needed to move into the new office within a month.
We spent around two weeks discussing and agreeing all the details before the work started. What I really appreciated was that everything we agreed beforehand was actually followed through during the job. The work was also completed on time.
Thanks to the whole Сraftex team for a great job. I’d definitely use them again if we need any work done in the future.IURII PYLYPETS

We recently worked with Craftex and honestly couldn’t be happier with the results. From start to finish, the team was professional, reliable, and highly skilled. The quality of workmanship exceeded our expectations, and everything was completed on time and to a very high standard.
Communication throughout the project was excellent, and they always went above and beyond to make sure we were satisfied. It’s rare to find a construction company that combines professionalism, attention to detail, and great customer service so well.
Without a doubt, Craftex is one of the best construction companies we have ever worked with. Highly recommended to anyone looking for quality and trustworthy builders.Adam Miah

Dmitriy consistently delivers courteous, prompt service and has shown great flexibility in accommodating last-minute changes to plans and timelines. I highly recommend Craftex for their professionalism and outstanding workmanship.

Hired Craftex to do the full design and fit out of my gym in Chelsea. Super efficient and fast team. They gave the best price and a proper fast track program. We managed to open in less than 6 weeks with no headaches or surprises during construction. Quality was great, we had zero snags on completion. I’ve worked with a few companies before but these guys really impressed me from project management to how they treat the client. Top GGs.

I worked perfectly with Sviat and Joe, with their architect they came up with a very smart design for our office to fit more desks and optimise the space to its maximum capacity. They also did excellent value engineering on the MEP design proposed by others, allowing us to save around £50K. The quality and speed were outstanding we finished two weeks ahead of schedule. Highly recommend these guys.

Happy with the end result. Tight timeline but they pulled it off. The team worked late shifts and even weekends to help us open the doors on schedule. Site was always left tidy at the end of the day and no surprise charges either. Good communication throughout. Would definitely use Craftex again.

Highly recommended!
Craftex are the kind of fit-out contractors in London you can truly trust. From the very first meeting, they understood our vision and gave practical ideas to make the most of our space. They turned our old storage area into a clean, efficient, and well-organized warehouse. The team was professional, easy to work with, and clearly took pride in their work.Monika Kamionka

We brought in Craftex to refurb our London office and honestly, they made the whole thing way easier than we expected. They listened, suggested ideas we wouldn’t have thought of, and explained everything clearly. Not the cheapest quote we got, but the end result shows why, the place looks modern, clean, and our team actually enjoys being here now. Communication was spot-on too. No chasing and confusion, deadlines were hit. If you want people who genuinely care and don’t treat your project like “another job,” I’d recommend them.

Sviat and his team at Craftex were brilliant to work with on our office redesign. From the first meeting, they took the time to understand how we actually use the space rather than just pitching generic solutions. They came back with clever, practical ideas to maximise use of the space and get more employees and desks inside . Every step was handled professionally, and the process felt surprisingly smooth for a project of this size. They finished one week ahead of schedule, and the transformation is clear — our office feels brighter, more functional, and much more welcoming. I’d happily recommend Craftex to anyone who wants a reliable design team that also makes the journey enjoyable.

We recently worked with Sviat and the Craftex team on a complete warehouse refurbishment, and the results have been outstanding. From the very beginning, their team was professional, organized, and attentive to every detail. The project was completed on time and within budget, without disrupting our day-to-day operations.

My experience with Craftex was excellent from beginning to end. They took the time to really listen to what I wanted and then offered practical suggestions that made the design even better. I always felt like they cared about creating a space that worked for me, not just one that looked nice on paper. The end result is an office that feels stylish, welcoming, and very functional for day-to-day work. The process itself was straightforward, well-managed, and never stressful. I’d definitely recommend Craftex if you’re looking for office design and build services in London — they made the whole journey a positive one.

I’m really pleased with my experience working with Craftex. As a commercial construction firm, they handled everything from start to finish without any unnecessary stress on my side. What impressed me was how they suggested practical ideas that improved the design while also keeping things realistic. The communication was always clear, so I never felt out of the loop. The project ran smoothly, deadlines were met, and the end result is exactly what I was hoping for — a space that feels both functional and modern. It’s not easy finding contractors who are this reliable, but Craftex definitely proved they can be trusted.

I had an amazing experience working with Sviat and the Craftex team on our office fit-out in London. They were always professional, responsive, and quick to offer the best advice whenever decisions needed to be made. I really appreciated how they balanced style with practicality — the office doesn’t just look fantastic, it works perfectly for our team. Everything was done with care and attention to detail, and the project never felt overwhelming because they managed it so well. Communication was clear from start to finish, and I always felt involved in the process. I would happily recommend Craftex to anyone looking for a trustworthy contractor.

Craftex carried out a warehouse fit-out for us, and I couldn’t be happier with the outcome. The space has been completely transformed into a highly organized and efficient environment that makes our daily operations much smoother.
The team was professional but also very approachable — I always felt comfortable asking questions or giving feedback. They came up with smart, practical solutions that worked perfectly for our setup, and everything was explained clearly along the way.
The best part was how they stuck to the agreed timeline, finishing on schedule without cutting corners. It’s rare to get both quality and reliability, but Craftex delivered both.Roma Shchukin

I can honestly say our office has been completely transformed thanks to Craftex. From the very first meeting, the team was approachable, professional, and full of creative ideas that really made sense for our business. They didn’t just focus on how the space would look but also how it would work for the team day-to-day. The new layout is efficient, modern, and welcoming, and you can tell they really thought about the details. The whole process was smooth and surprisingly stress-free. They kept me updated at every stage, which gave me confidence. I’m really happy with the results and wouldn’t hesitate to recommend them to anyone.

The results from Craftex’s commercial refurbishment in London are fantastic. The team was friendly, clear in communication, and made sure the project stayed on track. The workspace now feels efficient, welcoming, and modern. Definitely a team you can trust!

We hired Craftex for a commercial ground floor fit-out with 2 flats above. There were some minor co-ordination hiccups with third-party suppliers but the team kept it moving. Finish quality was strong. Kitchens and doors look great. I have already asked them for a quote on the next project.

These guys actually deliver. They handled our first industrial to residential conversion near Tower Bridge, turned an old warehouse into 4 modern flats. They stuck to the plan, kept the site clean and the timing was on point. No hidden extras, no drama, just a professional construction company in London that gets the job done.

We recently hired Craftex for a commercial office fit-out project in Central London, and overall, we’re really happy with the result. There was a delay on our side with a custom glass partition supplier, but the Craftex team managed the construction schedule very professionally and kept everything on track. Their guys worked clean, respected our workspace and IT setup, and kept the site tidy throughout. If you're looking for a reliable office refurbishment company in London, I’d definitely recommend Craftex. Would use them again without hesitation.

This was a full high-end renovation of my Victorian rental apartment in Westminster, just off Sloane Square and Belgravia. The scope included full fit-out: electrics, plumbing, a new bespoke kitchen, and a luxury bathroom refurbishment. Craftex took care of everything and made the process easy. They weren’t the cheapest, but you can tell they really know what they’re doing when it comes to prime London property renovations.
The team was professional, organised, and genuinely seemed to care about getting everything right. I was especially impressed with the quality of the finish – the attention to detail really shows in every corner.
I’m very happy with the results and would definitely recommend Craftex to anyone looking for reliable, high-quality renovation work in Central London.Наталия Цимбалюк

I was stressed about timing since we had bookings lined up, but they smashed it. Even worked Saturday to finish the floor. My clients love the look — the beauty salon fit-out turned out exactly how I wanted. Couldn’t have pulled it off without their help. Genuinely appreciate the way they communicated throughout the refurbishment. If you need reliable help with beauty salon design or fit-out, especially in a place like Chelsea — these are the guys.

We used Craftex for a shop-to-flat conversion in Chelsea — turning an old retail space into two rental units. Access wasn’t the easiest, but the guys handled it well, no drama. Quote was clear, no hidden extras, and they actually stuck to it, which is rare. Finish came out solid, exactly what we needed for rentals. Joe (PM) kept things ticking and communication was always on point. All in all, smooth job — would use them again for sure.👍

Fuse Energy hired Craftex on the fit-out and installation of our engineering and research centre, which included electrical, heating, lighting, plumbing, and ventilation upgrades. They delivered everything to a high standard and were proactive throughout — even working weekends to help speed up the programme, despite not being contracted to. They managed last-minute changes very well, communication was clear and consistent, and the team was professional from start to finish. We’d happily recommend Craftex to anyone needing a reliable construction partner.

Amazing experience with these guys. I trusted them my apartment in London and Business. They are always accurate, very professional, responsive and neat. They would always advice me right things for my best interest. I had luxury experience with them and I would definitely recommend Craftex to everyone.

Could not be HAPPIER with Sviat and the Craftex team, they certainly showed me that they’re the number one office design company in London that we’ve had the pleasure of working with. They gave us a unique design just like we wanted, and we loved the first initial draft of the concept. Also have to give them props for Construction, I gave them a tight timeline as we needed to move our team in ASAP, so they pulled double shifts and I didn’t see a drop in quality. Will be to talking to the team when we move up to our next bigger office. Highly recommended A+++

I and my husband are very satisfied with Craftex's service and customer support. We bought a house in Hampstead and wanted to redesign and renovate it. On our initial free consultation with Sviat, we found out that we actually can do loft conversion and rear extension and add value to the property straight away.
We worked with the Craftex design team to bring our vision to life and deliver planning approvals. At that time guys started stripping out to save time on the construction programme as we wanted to move in ASAP.
We worked with very experienced project director Konstantin who was responsible for all aspects of project delivery from design to construction with a very good eye on details and customer care.
We saved a lot of money by having professional advice from the start. Project management and quality at Craftex are at the highest level. Many thanks to Craftex Team.Lia Lavryk

Design and build: your questions
What is a turnkey contract in construction?
One contractor takes responsibility for the whole project, from brief and design through construction to handover, and gives you the finished building ready to use. You deal with one team and one contract.
What is the difference between turnkey and design and build?
They overlap. Under design and build the contractor designs and builds to your requirements; turnkey usually goes further, covering everything until the space is ready to use, including fit-out and furniture. We offer both.
Why not hire an architect and a builder separately?
You can, but the gap between them is where cost and time leak: a design the builder prices higher than expected, or questions no one owns on site. With one team, design and price are checked against each other from day one.
What size of project do you take on?
Design and build projects from £100,000 to £10M+. Recent examples include Medusa (£460K, 17 weeks) and Portsoken House (£2.2M, 7 months).
Do you work on commercial and residential projects?
Both. Commercial work includes offices, clinics and warehouses; on the residential side we were main contractor for the Kensington Olympia penthouse from concept to completion.
Who manages the project?
Our own project managers, as your single point of contact. Prefer a client-side manager over your own contractors? See construction project management.
