4.3 x 6m single storey extension

⭐⭐⭐⭐⭐
Simon was extremely efficient in the way his team go about the work. He completed the extension in under 5 weeks (whereas others were quoting 3 months). The speed at which his team go is by no means to the detriment of the quality of the build. Undertook variations to the build during the course of works and didn't try to rip me off on costs for these. Would HIGHLY recommend to all!!!!

Garage Conversion and 3m Single Storey Extension

⭐⭐⭐⭐⭐
Simon has done a great job - done effectively a full ground renovation in just under 10 weeks as agreed. We now have a new extension with new floor, kitchen, underfloor heating etc, and also the garage conversion has been completed giving us some smart new rooms and some breathing space!  We have since hired him again to do the cladding on the front of the house and would recommend him.

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.

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 everytime. Their work rate is second to none aswell 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 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.

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.

Loft Conversion required for 30's semi

⭐⭐⭐⭐⭐
We hired Go Gondolier to do our hip to Gable loft conversion. We are very happy with the finished job and couldn’t recommend go gondolier highly enough.The job was done to a very high standard, Simon promised to finish within six weeks and he finished early which also included decoration as a favour that wasn’t in the original quote. Simon is a very nice guy and very honest and his team are very pleasant, they work very hard and they were work very long hours. They are also very tidy and cleaned up every day. Simon is the best builder I have ever worked with and will be sure to hire him to do our kitchen extension. Payment terms are also very fair, weekly payments as opposed to other competitors that charged a large amount upfront. Simon has a very keen eye for detail and Advised us on improvements on the original drawings done by the architect which made a big difference to the finish. His communication skills are also excellent, he always picks up his phone and always responds to emails the same day. We are absolutely delighted with our loft conversion and can’t recommend go gondolier highly enough.

Loft conversion

⭐⭐⭐⭐⭐
We contacted Simon about taking over our loft conversion after being let down by a builder who in 2 months had only just begun to lay the joists. We are more than pleased with the rapid transformation of our old loft space into two new rooms and beautifully tiled bathroom in just six weeks by Simon and his hardworking team. They accomplished this by putting in long days, often 8-6, working solidly in all weathers and with minimal disruption to our household. The builders were polite and considerate and tidied up well at the end of each day. Simon was happy to acomodate several additions and alterations as the build progressed. We've been impressed with the standard of work and all done within a very reasonable budget. We'd readily recommend Go Gondolier to anyone planning on doing a loft conversion, or doing other building works.

Bungalow loft conversion

⭐⭐⭐⭐⭐
We hired go gondolier to do the loft conversion on my mums bungalow and Simon his team of builders were exceptional from start to finish . arriving early in the morning and leaving sometimes after 6 pm .the loft was completed in half the time that we expected. they left the site tidy every day , built the loft exactly to plan , and any snagging was dealt with . 3 of our neighbours have seen the work and were amazed with the job done . I would recommend go - gondolier to anyone looking to have any sort of building work done and I look forward to hiring them in the future

1 Bed Flat Refurb

⭐⭐⭐⭐⭐
I had originally overlooked this company, as I was looking at builders with a minimum of 100 positive feedback. I then came across them on the Federation of Master Builders, so decided to invite them to quote. From my first meeting with Simon his honesty and experience was apparent and decided to hire Go Gondolier Ltd for this job.
The work was originally estimates to take 14 working days it was completed in just 10 days! Simon and his team worked long days and weekends to get the job completed ahead of time. He was a great project manager and a pleasure to deal with. They always left the place clean and tidy.
As with all building work there were hiccups along the way (wrong toilet delivered), which meant Simon had to come back and finish the job. Simon was true to his words and came back!
In my opinion, Simon's unique selling point is his attention to detail and high standards. He thought of all the little details that I had missed on my schedule of work. He puts himself in the clients position and thinks of what they need. I am really pleased with the standard of work and will definitely be getting Simon back to do the kitchen and any future projects that I may have. I highly recommend Simon and his team, you are in safe hands.

Bedroom refurbishment

⭐⭐⭐⭐⭐
Simon and his team were hired to replace a ceiling, plaster the walls, add spotlights and new electric sockets in our bedroom. We added a few things last minute and they were happy to accommodate us. They were professional and easy to communicate with. I would definitely recommend them and will hire them again when we're ready to refurbish the master bedroom.

Loft Ladder-in need of repair

⭐⭐⭐⭐⭐
Mine was a simple job but required professional attention. Simon turned up with his team earlier than expected and waited for me to get home. He came equipped with parts and a good team who had the work assessed, estimated and completed in less than half hour. Straight forward job, professional service, very reasonable fee, no fuss and left premises clean and tidy with a one and half years warranty. I couldn't have asked for more and thank Simon & team for a job well done. Sajid
