Extensions- 22 Apr 2019
Richard and his team have always been very hard working, respectful and professional throughout the project. We have had an extension, utility and bathroom/toilet renovation and we are very happy with the quality of work. It has transformed our home into a beautiful living space. Richard was very helpful when giving advice on materials we were choosing. The team were very accommodating to our needs, easy to work with and always tidied up after themselves. The payment schedule made it easy to keep on top of the budget and pay for any optional extras along the way. The building work was completed within the set timescale and to a high standard. We would highly recommend Lux for any building/renovation work.

Extensions- 31 Oct 2019
Sam built a 9 meter by 4 meter ground floor extension for us, it has 2 rooms, 2 large sky lights, french doors and a patio. The build came in on time and on budget, Sam and his guys where always friendly and courteous, would explain what was going on and made sure we where happy with everything. We have autistic boys, one of them likes to know whats happening at all times and wanted to help and ask question non stop, the guys where absolutely brilliant with them, even letting them lay some bricks. I could not have asked for better workman when it came to my boys! We are very happy with our extension, it has made a massive difference to our home and lives. We have no problem at all in highly recommending Sam to anyone!! Shel & Jim Aitken
