Very professional. Arrived on time, immediately started putting down floor protection from the front door right the way through to the studio room. Said what time they would be finished and actually finished a little early. Did a good job of cleaning up after. And as for the plastering, it’s some of the best I’ve seen! Absolutely fantastic. I would thoroughly recommend them, and would use them again in a heartbeat!

George contacted me within hours of my posting the job and visited the next day. His quote was reasonable and he stuck to it. He arrived when he said he would and was meticulous in carrying out the requested job, clearing up afterwards. He is skilful and courteous. I will have no hesitation hiring George for other tasks in future and recommend him wholeheartedly.

Unfortunately I disagree. I posted this as one job and can prove this so will be taking this further. I also paid most of the money. Scott only called back after the tenant was fed up of the job being left unfinished for many many months. He also left a ceiling light hanging which was a health and safety concern and refuses to provide his insurance details.

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 !
