About Me
I help homeowners across Northern Ireland with extensions, loft conversions, garage conversions and internal alterations. My focus is on clear advice, practical solutions and accurate drawings that make Planning Permission and Building Control as straightforward as possible.
With over 40 years’ experience preparing planning and construction drawings, I take a practical, friendly approach to design. I listen carefully, explain everything in plain English and create spaces that feel natural, buildable and cost‑aware. No jargon. No fuss. Just a calm, steady process from first ideas to final approval.
I began my career in 1986 with Hamilton Architects, working on a wide range of projects. Over the years I supported architects delivering both commercial and residential schemes across Northern Ireland. In 2004, I founded GT Building Design to focus on what I enjoy most — helping families transform their homes with practical, well‑considered design. Today, I still handle every project personally, from the first conversation to the final set of drawings.

What Clients Say
Albert M
"Glenn recently completed the design and architectural work for me taking his detailed drawings right through the planning office process and building control.
From the moment I met with Glenn at my property I felt comfortable. Glenn has been doing design and the architectural drawings for more than 35 years. It’s easy to tell he takes great pride in his work and will take the time to get it just right for you with your feedback.
His drawings are very detailed that in my case it enabled the planning office to grant the approval without changes. Great job Glenn."
Tommy C
"Embarking on any building project can be a very daunting task…
From the outset Glenn impressed us with his knowledge, professional approach and enthusiasm for our project.
He designed us the ideal home making full and best use of our site. Importantly Glenn also produced a comprehensive 34‑page tender document covering all aspects of the build that proved to be invaluable.
We thank Glenn hugely for helping us with what could have been a very stressful experience, and helping us achieve our dream home."
Ross M
“I got in touch with GT Building Design about the possibility of a kitchen extension…
Right from the first email, I knew Glenn was the right man for our project.
Glenn’s final plans for our project are extremely detailed and they sailed through planning and building control with ease due to his extensive knowledge and experience.
We cannot wait to begin work on our dream kitchen space and we have nothing but good words to say about working with GT Building Design.”
