Hard Flooring- 29 Dec 2018
Giuseppe and his team are top level professionals able to give qualified advice and real expertise. In renovating our art gallery, they showed real old-time mastery from the beginning. They not only helped us study the most suitable solutions for the features of our place both for the flooring and the walls painting, but also showed amazing precision and care in carrying out the whole renovation project by applying the renowned knowledge of Italian master masons. While other builders had cursorily told us that any laminate would be good, the one that Giuseppe and team suggested us was selected by considering both the resistance to the clomping and the desired aesthetic result. Also, they adopted all the special arrangements needed to prevent the wood floor from bulging and lifting. They suggested us the type and the colour for the skirting board, making the gallery even more refined. The works were terminated in the estimated time and the fantastic result in terms of elegance, sophistication and safety has been possible thanks to the reliability and attention to detail of Giuseppe and team. We were so satisfied that we decided to hire them for all the other works needed (ceiling painting, walls painting, positioning of the anti UV film in our windows, enforcement and lifting up of the electrical track for the lighting system). All these works were completed with mastery and are still contributing to fascinate all the visitors at the gallery!

Extensions- 28 Jul 2017
Tony and his team recently completed a large ground floor extension. The guys were polite and courteous, on time every day, worked hard through the day and kept a clean and tidy site. Tony was very good at anticipating issues before they arose, making useful suggestions and giving us time to plan. We had a previous bad experience with a cowboy builder and Tony was especially sympathetic and understanding. Tony and his team were always transparent and upfront and very easy to work with. Tony was recommended by neighbours that he had worked for and we would also highly recommend him.

Garden Maintenance- 17 Sep 2017
I hired DS Developments to completely landscape my small front garden. This involved clearing and levelling the area; moving and re-securing a bike shed; laying a patio and lawn; and a number of finishing touches. The area went from somewhat of an embarrassing eye-sore to an area of pride. One that several neighbours have already made compliments about. David provided a professional service from start to finish. His quote was more than I expected, but his knowledge and vision gave me the confidence to select his services. He provided a selection of options and stuck to budget; adapted well to new ideas/suggestions; and informed in advance where the cost would be impacted. He and his team also were as tidy and considerate as possible and I highly recommend their services.

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.

Extensions- 6 Jun 2021
I requested quotes from 10+ builders, regardless of their price I already knew I was going with KHbuilder as instantly they seemed genuine & trustworthy! Hasan never changed his price during the project which is a fear many have during a build, he has a great team, friendly and always courteous. His workmanship is very good, therefore he is now also doing my patio and garage, he has great suggestions and contacts which has saved us money. His attention to detail and reliability really does shine through, our neighbor is now also doing the exact same 4 meter extension with a new kitchen move, the fibre glass roof and the bifolds all starting to take shape and look fantastic, just search for KHBuilder on instagram where they have posted the progress so far of all the work being done! We will genuinely miss all the guys being around. A very rare find in the building trade!! Thanks KH Builder...

Extensions- 24 Jun 2017
We had a large piece of work done by Johan and his team. It was a 4m single storey rear extension with new kitchen installation, converting the old kitchen into a downstairs bathroom and utility room, plus other bits and bobs like new boiler, rear patio. We got quotes from a few builders, Home Renovations weren't the cheapest, they were actually towards the higher end. But we went and saw their previous work and spoke to some of their other clients. The work was done to a high quality and the clients seemed to be happy so we decided to go with them. Johan's team are very hard working, professional and polite. Pawel and his team of builders, bricklayers, plumbers, electricians, etc. would turn up before 8am and finish at 6pm working solidly throughout the day. There is Magda as the project manager who keeps you in the loop, and answers any of your questions (which we had many). There is Michaela on the finance side who keeps you up to date with the budget. Our budget went over by 5% with "variations" (extra work or materials) but it was always communicated why and the work wasn't done without our approval. Pawel would give his recommendations but the final word would always be ours. But these things can add up. Overall we were very happy with the build, it was done to a very high standard. They also finished it before time. They said it would take 12 weeks in fact they finished it in 10 weeks which was amazing as you would normally expect these things to go over.

We had the pleasure of working with Alfa Style Limited on our loft conversion and we can recommend them highly and without reservation. Their work is incredible, attention to detail outstanding – our build was done with care and precision. They turned up on time every day, worked incredibly hard and quickly. In addition, they were extremely clean and tidy in the workplace – they never left the worksite in disarray. This is the first time we have done such a big project – Ruslan, Slava and their team were amazing. They were brilliant at explaining what was going to happen, day by day, week by week and translated the more technical information! No question or query was too much. The service after the build had finished has also been great, calls to check everything is OK and any queries we have, they are only a phone call away. We have had so many compliments from family and friends who have seen the finished build … it has made a huge difference to our house, we could not be happier.

Extensions- 4 Dec 2023
Happy with the quality of work and team was very friendly, everyday leaving the house livable for me and my wife while work was ongoing. Sohail offered good advice throughout the project and ended with shell completed after 8 weeks. Definitely reccomend getting a digger for excavation as we started building walls after 6 days, very fast! There were some minor delays as there are multiple projects going on in parallel, fitting in with timelines which is understandable as the team is very experienced and in high demand. Snag fixes were done promptly and all work signed off with building control. I would happily work with Sohail & team again, they have left the job with another satisfied customer - I think they turned out to be the best people to do the job, highly reccomend!
