Incredibly happy with Admir and the team. Very professional, punctual, tidy, great finishes and a problem solver. We created a very challenging kitchen to finish, and they did an incredible job. Super happy to finally find someone that I can trust.

D.L.CONS LTD
Rating: 5 out of 5
Extension Builder in South Kensington
Hi, I’m Dan, the owner of D.L.CONS LTD – a small, skilled, and reliable building company based in E9, London. With 25+ years of experience, I’ve pretty much done it all – and done it well. I specialize in bathroom and kitchen fitting, bricklaying, painting & decorating, and carpentry, and over the years, I’ve worked on everything from domestic extensions to shop renovations. Whether it's transforming a small bathroom or building an entire extension, my team and I focus on quality, precision, and attention to detail—because great craftsmanship speaks for itself. We mainly work in E9 and the surrounding high-end postcodes—Hackney, Victoria Park, London Fields,and Islington. If you're looking for top-quality workmanship with no shortcuts, I’d love to hear about your project. Let’s build something great together.

Carpentry- 8 Apr 2026
I’m really happy with the work carried out. He came in to fix my steps after a previous builder had damaged them and left them unstable, and the difference is night and day. Everything now feels solid, secure and properly finished. He also fixed the skirting boards and installed my desk, all to a very high standard. What I really appreciated was how professional he was throughout and the advice he gave along the way, which showed real experience and care for the job. Overall, a really high-quality finish and a great attitude. I wouldn’t hesitate to recommend him.

Restoration & Refurbishment- 15 Feb 2016
Pawel and his team modernised our two bedroom house from top to bottom. They installed central heating in every room, they removed our old warm air heating, made an open plan for the kitchen and living room area, installed new bathroom and kitchen units and did the tiling too, they updated our electrics and sockets and also plastered and painted the walls and fitted our wooden flooring for downstairs. The job was completed within 12 weeks. We were very happy with the modernisation, our home looks completely different and has a new modern fresh feel. We will definately be using Pawel and his team for future jobs. Thanks again Khalima

Handyman- 23 Mar 2022
Alex and his crew did a fantastic job on my property. They did the work on-time, to budget and to a very professional standard. The work required a wide variety of skills from painting, carpentry, plumbing and electrics. As I was unable to be on site Alex constantly kept me updated on progress with photos and videos. All in all I would highly recommend Alex and his team.

We did a lot of research ahead of our loft build, and spoke to customers of the companies we looked at. We were impressed with Toma and her team from the outset, especially in terms of clarity and communication. We sat down with the project team at the start and walked through the week-by-week plan for our build, then a whatsapp group and weekly meets meant we knew exactly what was happening throughout. Our endless questions were responded to swiftly. Additional optional trade-ups (eg top-hung windows, larger bathroom window etc) were discussed and explained with context, sound advice (and clear pricing where nec) but always still optional. Toma's communication with the teams also seemed strong and continuous, with materials always arriving in time and ahead of when needed, no down-days etc - and importantly, the teams all seemed happy and were just lovely people to have around. I realise with hindsight too that the team's care and workmanship really put them a cut above many others in my area and the project remained on schedule. I wouldn't hesitate to recommend ICS for the whole package and in fact we've also chosen to use them again for a kitchen extension.

Bathroom Fitting- 20 Jan 2023
We highly recommend Mario & his team. They fitted a new kitchen & bathroom to a really high standard within a short, timeframe. They work hard, are friendly, professional & honest, my neighbour even commented on how considerate they were! Upon first meeting Mario we were impressed by how organised he was. He arrived on time with the description we’d posted on my builder & went through it methodically. We had A LOT of questions! He answered all of them & didn’t rush us. We received a competitive quote within a day as promised. It included everything we discussed & he quickly answered our follow up questions. We wanted an accurate idea of the cost of electrical work & Mario arranged for his electrician to come & inspect/quote before we’d appointed Mario the job. Our kitchen & bathroom is complicated, with lots of difficult angles. Damp, unlevel floor, unlevel windows, a low ceiling were uncovered in the bathroom. Mario did well to identify solutions, giving us expert advice. Pipes were neatly chased into the wall. Underfloor heating & LVT, tiling, grouting & painting all done to a very professional finish. He kept us informed of progress, checked our preferences & was patient when we had supply delays, finding ways to ensure the job finished on time enabling us to move from our temporary accommodation back home in time for Christmas. He promptly fixed some minor issues after the job finished. We highly recommend Mario & would use him again.

Bricklaying- 29 May 2026
Giani and his colleague repaired our wall beautifully for a reasonable price. He talked us through the issues that caused the wall to fail and explained what needed doing. He started the job the next morning arriving promptly and then went about the job with care and pride. I can whole heartedly recommend AGB Construction to anyone looking for builders with good communication, a sincere pride in their work and honest fair pricing.

RS Building successfully delivered two full back-to-brick refurbishments and a new-build development for us in Greenwich, including demolition and construction of four new dwellings. Their level of workmanship is exceptional, and their attention to detail is second to none. As experienced property developers, we’ve worked with many contractors—but RS Building stand out for their reliability, quality, and professionalism. We have since recommended them to several colleagues, all of whom have been equally impressed. Our only regret is not finding them sooner. We look forward to working with them again on future projects.

Restoration & Refurbishment- 16 Feb 2018
Adam and his team did a brilliant job! My flat was in very bad condition. They gutted the whole flat and refurbished everything to a very high standard. Work performed included, new boiler and radiators installation, complete refit of bathroom and kitchen including all tiling, plumbing and electrics, new spotlights and wooden flooring throughout, new doors and skirting boards and all painting and decorating. They also arranged for all skips and rubbish clearance. I simply left the keys with Adam and he performed all work with minimum guidance. I would touch base a couple of times every week or when things needed to be discussed. He was happy to purchase most materials and provide receipts. I would highly recommend Adam and will definitely use him again for future work.

Extensions- 24 May 2024
We asked BLG to complete a different job to the one we advertised as weren't ready to start it. Instead they completed a 2 bedroom flat renovation, including ripping out and installation of kitchen, removing plasterboard walls, making good, painting and decorating and recarpeting/tiling. Their work and professionalism was great but even better was their attitude. They were always quick to find good solutions to problems, were extremely accomodating, informative, hard working and prices were very reasonable - at no point did I feel I was being ripped off or being treated like a mug, which after completing multiple renovations in the past am well aware of. I wouldn't hesitate to recommend them.

Bathroom Fitting- 10 Oct 2024
Really good team. The work was excellent. The only thing to comment is that the team could have finished the work faster but overall I’m happy with their work. Very involved and caring team. It felt like they were doing their own bathroom. Good price as well.
