Undertook extensive building work - a rear and side extension, built a summer house, landscaped the garden and paved a new driveway. They are the best building company I have ever worked with. Courteous, tidy, excellent quality, considerate of our family and our neighbours. Afrim consistently gone went and beyond to ensure that my renovations were completed to a high standard and at a fast pace. I am so pleased I made the decision to let him manage the building work from start to finish as his electrician, plumber, tilers, kitchen fitters have all been fantastic. Building works can be extremely stressful but Afrim did everything to make sure it has been as smooth as possible - would highly recommend

Extensions- 13 Jan 2019
George was excellent throughout - would highly recommend. Although I did not hire George to complete the whole job (as someone in my family is a bricklayer) he was instrumental in completing the build. A few points to demonstrate: - Fair and transparent quote (which was stuck to); - Flexible throughout delays caused by me (planning, etc.); - Supportive (advice on what he would do if he was running whole job); - Professional (including team). I will use him again.

Extensions- 27 Jun 2022
Very very happy with Michael's work. From the day one of the meet till end of the project, he and his team been quite professional and have been working with high standards. We received range of quotes from different builders and Michael's quote was somewhere in middle with good quality of work which we have seen during our site visit for his other projects. So, decided to go with him. One really good thing you get from Michael is plenty of ideas and options. From our original drawings, he suggested some changes which were really useful. Being a lay people, During the project we were confused in some design options and Michael really assisted with 3 to 4 options and he suggests which one is the best from his view point but also been flexible if we wanted to do in specific way. He was daily coming to the site to monitor quality and progress of the work. All his team is highly skilled and experienced. The all do general building but when it comes to specific, they have specific tiles, electrician, plumber, painter etc etc who finishes the job at very high quality. They work flexible to complete the job on time and keep the area safe and tidy. In terms of managing project in budget, we had a good experience where Michael will in detail explain what is covered in agreed amount and where the extra cost will incur if there are major changes. I am taking this much time to write this review so that it can help others to see my good experience with Michael. 100% best.

We can't recommend Vince and Swift Design and Build highly enough. Vince made the impossible possible! He arrived on time and left the site clean and tidy at the end of every day. Vince had great suggestions to tweaks and changes we could make when problems arose, making us feel at ease during the whole project. We are very pleased with the end result and will definitely be recommending Vince to others. Thank you Vince!

What experience do you have with similar extensions in Redhill?
