The Noah
Single / Double Glazing
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 !
I have been in the trade for many years, (17 years) I have recently gone on my own, and my business is doing really well, I take pride in my work and it's what I enjoy doing. I always hit my targets and it's shown because my business is doing brilliant
Martin did an incredible job of putting up my curtain poles and I’d recommend him to anyone in need of a handy man.
.I have my tools for all jobs, I like to work very ordered and responsibility.thanks
Excellent and prompt service, and is cool and calm no matter how big the challenge.
