We have been working with Derek Borkiewicz (Sebek Construction) on a renovation of a garden flat in Little Venice since last autumn. We needed to completely restore the whole flat, including the garden. This was our second renovation project and by this time we knew what we wanted to do, which mistakes to avoid and what to pretend from a qualified builder. We will never stop saying how lucky we have been to find Derek and his team! Derek is not only a professional builder who is very careful to the smallest of the details. He is not only a very good project manager who is constantly checking the work of his men. Derek is a friend who takes on board a project like it is his own project. He suggested the most convenient and best solutions for any problem we came across during the works. There wasn’t a time when he didn’t know what to do to solve a difficult situation (and there are lots of small and big issues coming up in a renovation work) no matter how complicate they were and how long it took to solve them. His availability and his courtesy are incredible above all in a fast running city like London. This is priceless to us. His hard work can be seen in the wonderful result we reached with this garden flat. If we ever decide to work on another project we won’t think twice about working with Derek once again. In fact, now that we found the perfect man to work with, we are looking forward to finding another renovation project to work on! Monica

I recently had extensive work completed in my flat by Vas, and I couldn’t be happier with the result. The service was excellent from start to finish. Not only was the quality of the work consistently high, but the whole experience was smooth and stress-free. What really stood out was Vas’s level of skill and versatility. Every aspect of the project was handled with care and professionalism — from plumbing and new water heating pipes, to new electrics, installing a new kitchen, laying a beautiful wooden floor, renovating the bathroom, and even replacing doors with a sliding door system. Each element was completed to a very high standard. On top of that, Vas was friendly, proactive, and easy to communicate with throughout. Nothing ever felt like too much trouble, and it was clear he takes real pride in delivering great results. It was genuinely a pleasure to deal with Vas, and I would highly recommend his services to anyone looking for reliable, high-quality work. Thank you again!

Conversions - General- 30 Jun 2017
The project was a complete renovation of 2 bedroom period flat - adjusting internal walls, new kitchen, 2 new bathrooms, electrics, boiler, rads, new floor etc + full decoration. The Home Design & Build team were fantastic from start to finish - I'd give them 5 stars and would fully recommend. The quality of the work is outstanding - great craftsmanship and attention to detail + a very 'can-do' attitude to the bespoke elements and alterations that occurred throughout the project. The quote was clear and competitive, and the project stayed on budget aside from a few small additions to the scope which were added on at fair and transparent rates. It also stayed within the planned timescales (which is a first from my experience) and the team worked hard to complete on time. Both Lalli (who managed the project) and Mario (who led the work) were great to work with, highly capable and full of helpful and practical suggestions to the detail of the design.

If you are looking for a caring and conscientious builder then look no further than Stephen. Not only is he on your side for your project and budget, he gets the job done with absolute attention to detail. He works incredibly hard and is not satisfied till you, the client, are happy. He has a photographic, encyclopaedic memory for all things building and structural. He, with his extensive experience, is worth more on your project than any architect plans or drawings. Not only is he damned good at what he does, he’s polite and thorough. He also has a fantastic team that he keeps a close eye on at all times. There are no loud radios or requests for coffee. His team have a fixed break/lunch, bring their own supplies and I’m embarrassed to admit, leave your house tidier and cleaner than when they arrived - even when doing excavation/structural work! I offer only one word of caution, once Stephen and team are in, you won’t want them to leave, and you will start asking him to do all those other building jobs you never knew you wanted done! You will be very fortunate if you can secure him for your project. You can complete confidence in him, his team and their work.

Acelux did a brilliant job on our office refurb. We were very happy with the work completed as well as the service. They were able to come out of office hours during the bank holiday weekend, finish on time, and even stopped back in on Tuesday to make sure we were all happy with the works.

We struggled to get anyone interested in our refurbishment project originally, Mark answered an ad for a small part of the job and ended up being able to take on the whole thing thankfully. Our project was to completely strip out a 1960's maisonette flat, install internal insulation which involved extensive battening of all the external walls, new plasterboarding & plastering finishes to walls and ceilings, tiling and a completely new bathroom and kitchen install. To complicate things further, as enthusiastic DIY-ers we wanted to do lots of works ourselves as well and few builders would have worked alongside novices as well as Mark did. He was always happy to give advice or take over works when we realised they were beyond our skills or time ;-) Our project was constantly evolving and challenging - as we discovered hidden rotting floor joists and the joys of 60's engineering - door lintels - who needs those?! Mark was always there to help us problem solve and get the job done professionally and to high standards and this was all done throughout the challenging last year of lockdowns etc. Without hesitation we'd recommend Mark and his team. He was always reliable, flexible as the project developed and had excellent attention to detail and we couldn't have completed our project without him. Thank you Mark!

We were absolutely delighted with Lino and his services. He was incredibly patient , as our flat purchase was delayed. We required a total gutting off our flat, with new kitchen and bathroom, new flooring, painting, and all the rest. He had great communication throughout. He showed up on time with his team each day , and was so professional throughout. We went to Lino for advice throughout the process. He never said any of our plans were not possible- he always either said yes, or provided another option. This was such a great help. I would recommend Lino to anyone. We are absolutely delighted with our flat.

Negedet and his team are friendly, knowledgeable and simply brilliant. The work estimate was a crucial factor in choosing Velvet Construction and they went out of their way to delivered it. Their work pace is incredible without compromising on quality. They arrived when they said they would, were very respectful and very tidy at the end of each day. Negedet gave important advice when we were not quite sure and accommodated changes easily with no bother. The quality of the build is excellent and the finished work looks great.

Exquisite Design and Build recently reworked and refurbished our new, six bedroom detached house, having previously completed a kitchen extension at our last property. Andrei’s work is of an incredibly high standard. He shows great attention to detail throughout the entire process. Not only does he execute the work beautifully, but he offers great design ideas and and suggestions. With regard to contracting, pricing and invoicing, Andrei provides clear and accurate documentation which gives us complete trust in his ability to work within our budget. Andrei and his team are an absolute pleasure to work with; hardworking, punctual and tidy. I have recommended them to three other friends, all of whom chose to work with him on their extension/refurbishment projects and were equally delighted with the results. I would not hesitate to recommend Exquisite Design and Build to anyone, regardless of the size and complexity of their project.

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!
