Meet the Team

Steve James

Carpenter, joiner, roofer, tiler

My carpentry journey began over 30 years ago specialising in furniture upholstery and restoration, with a focus on fine antiques and high-quality bespoke furniture. I then spent time with Border Oak as a carpenter which saw me jetting off to the United States to work on some of their high end construction projects. Since then, I have continued working alongside highly skilled tradesmen on both small and large-scale projects. My work is defined by a commitment to craftsmanship and attention to detail delivering high-quality results tailored to each of our client’s needs.

Adam Morton

Carpenter, plasterer, roofer, tiler

I started my carpentry journey nearly 30 years ago in New Zealand. Upon returning to the UK, I began fitting kitchens for Möben before joining a local building firm, where I honed my trade for 10 years before striking out on my own. “It’s a real pleasure to get up in the morning and look forward to a day working with great colleagues doing a job I love!”

Testimonials

Robert & Sarah Gort, Llandrindod Wells

We couldn’t be more delighted with the experience we had working with this exceptional team of builders. From the very beginning, they demonstrated a level of professionalism, care, and attention to detail that immediately set them apart. The extension they created for our home has truly transformed the way we live. Every aspect of the build was completed to an incredibly high standard, with workmanship that is genuinely second to none. It’s clear that they take immense pride in what they do, and that pride is reflected in every detail of the finished space. What made the experience even more special was the people themselves. Over the course of the project, they became more than just builders — they became friends. Each member of the team was approachable, respectful, and consistently went above and beyond to ensure everything was just right. Communication was always clear, timelines were respected, and nothing ever felt like too much trouble. It’s rare to find a team that combines such outstanding skill with such warmth and integrity. We would wholeheartedly recommend them to anyone considering a building project — not only for the superb results they deliver, but for the genuinely positive experience they create along the way.

     
New Kitchen Extension

Martin and Sharon, Rhayader

On our first meeting with Adam to talk through our project of a kitchen extension, new decking area and complete refurbishment of our bungalow, we both felt from the onset that Adam was upfront, honest and approachable. After booking James Morton Cook Construction to do our work a site visit was also completed before the work commenced by Adam and Chris. Throughout the work Adam, Steve, Chris and Ian were polite, friendly, hard working, courteous and a pleasure to have in our home. They treated our renovation as if it were their own. In fact the whole team were genuinely nice people and although we were pleased when the project was finished we were sad to see them go as they felt like part of the family by the end of it. They were on site at 8am sharp and worked hard all day. They were reliable and always came when they said they would and we were kept informed of days when they were not with us. The work was outstanding and to a very high standard. The site was kept clean and tidy and was always tidied up at the end of the day. Communication was excellent before and throughout the project. When a decision was needed or an issue did arise, we were guided through the options and choices available to us. We were always kept informed and consulted at all stages of the project. They brought in their trusted plumber and electrician, which meant they would do the organising and chasing around to get the trades on site at the right time. making the project as stress free for us as possible. Even when the project was complete they were on hand to answer any questions, chase building regulations for us and they came back to do some snagging without any questions or hesitation. We are delighted with the finished results and how our bungalow has been transformed. We can thoroughly and unreservedly recommend James Morton Cook Construction and will use them in the future without hesitation. We have already recommended them to friends

     

Frances Thomas, Knighton

Adam and Steve have done many projects for me. I wouldn’t have anyone else. They have renovated a property for me, put in two kitchens and two bathrooms, to a fantastic spec. Their work is exceptionally neat and precise. They helped project manage when I was not around. I felt reassured that the decisions made on my behalf, were as I would have wanted. I would recommend JMC Construction for any building work.

     

Rich Ellison, Llandrindod Wells

Adam, Steve and Chris were the professionals redesigning and refurbishing the ground floor of our Edwardian house. This involved taking large parts of the house back to bare brick and partly no roof, then transforming into a lovely modern, warm space for modern living, without disrupting the period features found in much of the house. They also landscaped some of the garden to complete a beautiful living space in and out of the communal living area. They were more than just builders and carpenters. They made the architects plans work and altered things to make improvements. They were totally reliable and in my view very hard working. They made having construction in our home for a number of months actually quite pleasurable. I would definitely use them again.
