Mantas and the Mercury Building Solutions team have been excellent. We initially engaged them to build our loft extension but were so impressed with their speed, quality and attentive approach we decided to ask them to extend our downstairs as well. There were two elements to the project that really made me appreciate their quality. Firstly, whenever we encountered a problem with the build they were always available to discuss options and offer an opinion. Secondly, when the project completed and after we paid the final balance, Mantas kept in constant contact to ensure we were happy and even sent in a painter to touch up the property after we had moved back in. These are builders who you can always get hold of, work at pace and are competitively priced.

I used Mercury Building Solutions to undertake a Dormer extension on my 'two-up two down' property in 2018. It was always going to be a complicated build given the age of the property and the need to drop the ceilings. Throughout I found Mercury really easy to work with, they kept me informed as the build progressed and provided really helpful building suggestions when they could see ways of improving on the architectural drawings. The ultimate finish of the work was great, and it's been problem free since completion.

I used Mercury Building Solutions (through Simply Lofts) to build my loft conversion which was completed earlier this year. I am a bit of a perfectionist and they did a superb job. Their finish was excellent and for the work they did, the cost very reasonable. My loft layout wasn't straight forward which they had no issue in executing. I wouldn't hesitate in recommending them and use them again myself. Mantas who was my contact throughout the build was a pleasure to deal with.

I recommend Mercury Building Solutions. We had a loft extension built by this company. They have their own planning team which draws plans to submit to the council which was done fast. They also had building control sorted. We sat down and talked about ideas about how our loft should look, Mantas was very interested in our ideas and we felt positive about the project. Once the work had commenced, there was builders, plumbers, electricians, carpenters each set out with their own individual work. I liked this appoach because it was professional and everyone on the team was experienced. They came in and did what they had to do. I found that I could reach Mantas (project manager) with ease. And he was always happy to talk to me. The whole build took around 10 weeks, I have all the certifications from building control and the council. And the most important one of all, I have one happy wife. Good luck with your future projects Mantas and the team.

**Best builder ever ** I have used Mercury’s for a loft conversion in Tooting and they exceeded my expectations. Mantas, the owner and project manager, is responsive and always trying to help and provides great advice. The loft has enlarged the space of my flat and created a lot of light. Mantas really cares and uses his expertise to give good counsel to his clients. For example, he advised me to add a corner bench in the kitchen to maximise the seating space. He also advised me to add a roof light to flood the place with light. I am so pleased with the result. See pictures
