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.
