In clients’ words

Rear Extension


Was very happy with the work – single-storey extension. Was quoted 5 to 6 weeks to build and it was built in 3.5 weeks. They worked late many times and all of the team were good to deal with. They went above and beyond to make sure I was happy with the result. Would definitely recommend it.

Loft, double side and rear return


In 27 years, undoubtedly the best builder that I have ever employed. High standards, professional, clean and tidy, extremely quick! Simon is very pleasant, easy-going, very hardworking and even kept the neighbours happy. I no longer would use anybody else. Loft, double side extension, upper 3-metre bedroom extension and 6 metres back extension all completed in 4 months. Amazing!

2 Storey Extension

I hired Marius and his team to carry out my two storey extension, I can honestly say these are the best builders I have come across. From the minute I met him and he gave me my initial quote which was very reasonable I knew I would hire him. From the start to finish I was totally at ease. I never had any delays, they showed up when they said they would and on time every time. Their work rate is second to none as well I had quotes saying it would take 12-14 weeks from other builders whereas Marius completed mine in 8 weeks even though I added a couple of other improvements while the job was ongoing. My friends in the trade were gobsmacked by how quick they were. All in all, I wouldn’t have any doubts about employing them to carry out any building work for me in the future.

Kitchen Extension

Simon and his team carried out a full kitchen extension for me, including removing the rear structural wall, installing a new downstairs WC, new stud wall and full floor and kitchen installation. They were good value (not the cheapest, not the most expensive); did a good job; and worked very hard to complete the build in the shortest time frame possible (6 weeks all in, including kitchen fitting). Any changes were discussed before they went ahead and they brought some good ideas to the table too. I would be happy to recommend Simon and his team and happy to send through photos of the build as it progressed to anyone who is interested.

Loft conversion and 1st-floor bathroom refurb

Recently finished Loft conversion that Go Gondolier completed in SW19. Great finish all the works were completed a week earlier than planned from start to finish 6 weeks which is far quicker than others quoted! Simons team were all tidy, polite and hard working. Would highly recommend them for any builders works, decorating, plastering etc. Really happy with finish and the works that Simon completed for us, 5 star service.
