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...

Cocis Construction Group done the full interior painting of our 5 bedroom house and we are really happy with the result. The team was polite and worked very hard every day. They kept things clean and finished everything on time like they said they would. The paint finish looks great and the whole house feels fresh again. Would definitely recommend them if you need painting done.

Kitchen Fitting- 7 Jul 2016
Excellent! We hope to use again! I cannot recommend Alex & Richard highly enough. We had a full kitchen/diner knock through and complete refit. They were an absolute pleasure to have working at our house. From the moment they came round to quote for the work, they were pleasant, prompt, clear and concise. They were able to start work quickly which was great for us. The professionalism and attention to detail was amazing. Always arriving on time, they often stayed late to complete their work which lasted just over 2 weeks. They are a credit to the building industry and themselves. Our finished kitchen/diner looks amazing. We are so pleased. Please do not hesitate to hire these guys - you won't be disappointed!

Extensions- 27 Mar 2019
Luca & Team were very pleasant to work with. They suggested that we go for a bigger extension (3.6 x 8 m), which we eventually did as we had to go for planning permission anyway. Their quotation was reasonable and consistent, and we were impressed with a recent project they did which was a similar layout extension to our plans. They went an extra step always to make the project work for us. They built the rear extension, and then we asked them to add on the finishing (flooring, painting, decorating) and to install the kitchen that we purchased from Wren Kitchens. We were satisfied with their work on our project.
