Landscaping- 7 May 2026
“We recently had our landscaping redone along with new turf installation, and the results were excellent. The team was professional, punctual, and paid great attention to detail from start to finish. They completely transformed the garden, leaving everything neat, tidy, and looking amazing. The new turf was laid perfectly and has already made such a difference to the overall appearance of the space. Communication throughout the project was clear and friendly, and the workmanship was top quality. Highly recommend to anyone looking for reliable and skilled landscapers.”

Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.

Extensions- 30 Jan 2023
I had the pleasure of having them carry out a single story extension and fibreglass new roof of my property. I found they always turned up when specified and carried out fantastic quality work for a competitive price. Not being a builder you have to place trust in a person / company. They always made sure that we were happy keeping us updated with the project every step of the way. They were kind and considerate to our neighbours making sure they were not loud early in the morning or late in the evenings making the whole process run smoothly. I can not stress enough how great these guys are. Thanks

Conservatories- 14 Jun 2026
Wow, Xavia and his crew have done an amazing job replacing old polycarbonate conservatory roof with a solid tiled, insulated warm roof. I couldn't recommend these people enough, clean, curious, and experts in my opinion at all that they do. They went over and above when the weather changed to unforeseen heavy rain, and made sure we were watertight throughout. Lovely people, wonderful job, the best tradesmen I've met on my 64 years on this planet. Thank you.

What to ask a Haringey extension builder before hiring?

What qualifications and experience do you have as an extension builder in Haringey?

An extension builder in Haringey should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Haringey?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Haringey extension builder’s ability to deliver a result that meets your expectations.
