Ryan basically saved my bacon when my flat roof collapsed a week before I was due to go on holiday. His quote was very reasonable and he managed to shift some of his other jobs to come and replace both the roof and the ceiling two days after he gave me the quote. The work is of a very high standard and completed within two days, I would definately recommend Ryan for any of you building requirements

Very pleased with the work done, entire large garage roof replaced, Jordan and the team were very professional and hard working, got the job done sooner than expected as they worked longer days to get it done for us. Jordan took time to listen to our needs and our budget and did his upmost to keep the costs very affordable, without sacrificing on the quality of the work. Each day they ensured everything was clean and tidy. Would highly recommend and definitely use again if needed. Very happy customer

The Noah

Cellar & Basement Conversion

View ProfileRequest a quote

Ben’s journey in construction started at an early age. He grew up on construction sites alongside his father, who had a long-standing background in construction and worked directly on government projects. This gave Ben an early understanding of construction that came from being around real projects, real trades and the realities of building. He later studied Architecture, developing a deeper understanding of design, structure and how buildings come together. During this time, his passion for timber and craftsmanship became particularly strong. He discovered that what interested him most was not only designing buildings, but actually creating them. Before establishing NOAH Construction, Ben also gained experience working for leading construction companies, where he was exposed to projects worth millions of pounds and was involved in works with values reaching approximately £10 million. This experience gave him an understanding of the organisation, standards and responsibility required on larger construction projects. NOAH Construction was then established as a way to build something of his own. In just three years, the company has progressed from delivering smaller projects to successfully undertaking works ranging from approximately £50,000 to £1 million in value. Today, Ben combines three important parts of his background: hands-on construction experience from an early age, architectural education, and experience working within larger-scale construction environments. His particular passion remains timber and craftsmanship, but his approach to construction goes beyond one material or trade. The goal is to understand the project as a whole, build it properly and deliver work that he can stand behind. For Ben, NOAH Construction is the result of years spent around construction, studying architecture, learning from larger contractors and ultimately turning that experience into his own business. Hi, I'm Ben !
