Job was the removal of old, and installation of a new back garden gate and fence. Our house is end of terrace with a public path leading behind and down the side of the house, so security is a concern. Great initial discussion, with Niall helping us narrow down the best options and making sure we were happy. Workmanship, professionalism and reliability were all excellent and we're really happy with the final outcome. I would highly recommend Niall and 101 Construction & Landscaping, and will definitely be giving him a call again in the future.

Extensions- 22 May 2021
I was left in a mess by cowboy builders. I found Sukhvindsr Singh from mybuilders and then I had nothing to worry about. He completed the project with utmost responsibility from erecting heavy steals to all the way up to finish. I was amazed with the level of his skills and above all honesty. This was a massive 66sqm single storey extension and he put up structure, brickwork, fibreglass roof , underfloor heating , tiling,electric work . He even went beyond our agreement to do bits and pieces to make sure i donot get stressed out. I have given him another job in same property to do patio 88Sqm with porceline tiling. Feature wall prepared by him stood out . Highly recommended and i will be surprised if he does recieve similar feedback in his future jobs.

Bricklaying- 14 Aug 2019
Whilst i realised the work I required to be carried out may be too small of a job for some builders to consider it was great that Kyman Construction were happy to offer to view the job. Adam was highly professional right from the initial quotation phase through to completion, all work carried out to a high standard and i have no concern in recommending him for similar work.

Bathroom Fitting- 14 Nov 2019
We had our bathroom completely refurbished and Graham the owner was lovely. He came to give us the quote, visited whilst work was being undertaken to make sure everything was okay and came to make sure everything was finished to how we wanted it. The work carried out was of a high standard and whilst the bathroom work was being completed we also ended up getting our kitchen worktops done by Graham’s team. Chris was the one who carried out our work, he was very friendly and checked we were happy with the work he’d done before he left everyday. I would use Graham again for other work needed around the house.

Latest review:
Thegreenorigin Ltd worked on a full refurb of our office wash rooms in August last year. We had moved into new offices that had been completely renovated with the exception of the bathrooms, which were 20 years out of date! As a busy recruitment specialist in central London, we have an enormous amount of footfall through our offices on a daily basis, including those through our bathrooms, so the quality and resilience of the work was imperative. Thegreenorigin took time to understand our business priorities and worked throughout the night to allow us to maintain use of the bathrooms while they were doing the job. It meant we could still provide facilities to our clients (and staff) whilst they were being refurbished. This was a very important factor for us. In addition to this, they worked around issues which came to light regarding the building we worked in and old pipe work that was still in place, causing sewage issues and completed the project within the timeline we agreed. I would have no hesitation recommending them to other businesses or personal customers.
