An office or store at a Mayfair address, finished before the lease says it must be

Mayfair packs Georgian townhouses, headquarters floors, Bond Street and Savile Row flagships and members' clubs into a few hundred acres. Most of it is listed, in the conservation area, or owned by an estate with its own rules.

We survey the building, run the estate, landlord and council approvals, then design and build under one contract. Our Savile Row client kept trading for all 12 weeks of their refit.

How it works

How a Mayfair project runs with Craftex

01

Site visit and constraints check

We survey the building, confirm the listing, conservation-area and estate position for your address, and take your lease and opening dates.

02

Design priced as it develops

Our in-house team draws the layout, joinery and services; the people who will build it cost every option as it is drawn.

03

Approvals run for you

Estate consent, licence for alterations, listed building consent or planning where needed, building control, all submitted and tracked, the time built into the programme.

04

Build around your business

Zones, out-of-hours work and timed deliveries so clients and customers never meet a building site; noisy tasks when the street is quiet.

05

Test, certify, hand over

Every system tested, certificates and the health and safety file handed over, zero snags, before the date in your lease.

The Craftex Guide to Office Fit-Out

We walk you through every step of an office fit-out: the terms you will hear, what drives cost and programme, and the checklist that keeps your move date safe.

Our promises

Six promises, written into your contract

Not marketing lines. These are the terms we build to on every Mayfair project.

  1. One team, survey to keys

    Design, approvals and construction under one contract, one project manager, the same directors throughout.

  2. The agreed price stands

    A fixed figure for a written scope; every change priced and agreed in writing before the work.

    100% of projects on budget.

  3. Your business never stops

    Zoned works, nights and weekends, clean handback every morning.

    Drake's, Savile Row: open every day of a 12-week refit.

  4. Ready before your lease date

    Around 60% of the labour is our own, so no week is lost waiting for trades.

    Beaumont House: 750 sq m rebuilt in 3 weeks.

  5. £10M cover on every job

    Public and employers' liability, PI on request; ISO 9001, 14001 and 45001, CHAS and SafeContractor.

  6. Zero snags, every certificate

    We leave when it is right; every test certificate and consent, plus the safety file, with you before move-in.

Questions about building in Mayfair

Do I need listed building consent for an internal office fit-out in Mayfair?

If the building is listed, yes: consent covers the inside as well as the facade, and working without it is a criminal offence. Most of Mayfair is also in a conservation area, so shopfronts and external changes get closer scrutiny. We confirm the listing and conservation status at the first visit, prepare the drawings and heritage statement, and build the decision time into your programme.

What hours can we work on a Mayfair site, and what about the neighbours?

Westminster expects noisy work in weekday daytime hours and Saturday mornings, with nothing noisy on Sundays. For evening or weekend work we apply for prior consent under section 61 of the Control of Pollution Act, which fixes hours and noise levels before we start. On Savile Row we planned deliveries and shifts so the neighbours were not affected.

How long does an office refurbishment in Mayfair take?

Our Kensington office of 750 sq m took 3 weeks on site; a 120 sq m Savile Row flagship took 12 weeks while trading. Add time before site for the estate and listed-building approvals: we map them at the first visit so the date in your lease stays safe.

Who deals with Westminster City Council and building control?

We do. Our design and planning team prepares and submits the planning, listed building and building control applications, answers the officers' questions and manages the conditions, alongside the estate and landlord approvals.

Who approves alterations when the Grosvenor or Crown Estate is the freeholder?

The estate, as well as the council. Grosvenor runs its own management scheme for Mayfair and Belgravia and weighs the heritage significance of the building and the character of the area before it consents; structural changes are vetted by its engineers. Your immediate landlord also issues a licence for alterations. We prepare one package of drawings, specifications and method statements that serves all three.

Can our office or shop stay open during the works?

Yes. We split the floor into zones, do noisy work out of hours and hand the space back clean each morning. Drake's on Savile Row traded every day of its 12-week refit; at Portsoken House we built around occupied tenants at night and at weekends.

How much does an office fit-out in Mayfair cost?

Construction for a Cat B office runs about £67–114 per sq ft ex VAT, with furniture, AV and IT on top; the calculator above gives you a range in a minute. Listed-building repairs, estate conditions and out-of-hours working are priced per project. Send us the plan; a survey comes first, then you get a fixed figure.

What size of project do you take on in Mayfair?

Construction from £100,000 to £10M+: a single townhouse floor, a flagship store or a whole building. Our office is on Buckingham Palace Road, ten minutes away, so site visits are quick. Warehouses sit outside central London; see our warehouse refurbishment service.

What our clients say

See all reviews on Google
  • 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.

    Misha Levit

  • Great experience from start to finish. Communication was clear, the workmanship was excellent, and the whole project was managed professionally.

    Rhea Langford

  • 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

  • Craftex has completed a range of both small and large-scale projects on our commercial property with exceptional precision and quality. 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.

    Pascal Hunt

  • Great company to work with as always. Super flexible at dealing with evolving requirements and fast deployment and execution.

    Akshay Khanna

  • 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.

    Александр Хоменко

  • 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.

    John Smith

  • 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.

    Pawel Kamionka

  • 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.

    A Google User

  • 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.

    Cucu Iulian

  • 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.

    Simone Racaku

  • 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.

    Ion Bounegru

  • 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.

    Taron Papoyan

  • 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.

    Artur Dvorak

  • 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

  • We’re extremely happy with Sviat and the Craftex team’s work. They suggested clever ideas, managed the project efficiently, and delivered a functional, modern space. The team was easy to communicate with and very professional throughout the process!

    Polina Lysenko

  • 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.

    Mykyta Khadzhynov

  • 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!

    Alaa Betar

  • 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.

    Ben Edell

  • 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.

    Богдан Главацкий

  • 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.

    Ardian Beleshi

  • 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.

    Rami Jusupova

  • 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.👍

    Apartify Estates

  • 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.

    Hainro Eybers

  • Holistic therapy space fit-out
    Super impressed. I had a very specific vision for the studio. calm tones, soft lighting, hidden storage etc. the craftex team just got it. build was done quicker than I expected and the guys were polite, tidy and actually listened. we had 2 snags on day one but they fixed it before the week was out. worth it for the peace of mind.

    Dariia Shvyryda

  • Made a full refurbishment and redesign of our Central London office. Fantastic work, quality service and reliable people. Can recommend it to everybody

    Nikita Nigai

  • 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.

    Motush Motushev

  • 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+++

    Mikhail Burdoev

  • Very professional company. Craftex did brilliant minimalistic design and completely refurbished my apartment to the highest quality.

    Vlad

  • 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.
