Extensions are one of the most effective ways to transform a home. Whether you need more space for family life, a larger kitchen, a brighter living area or a better connection to your garden, a well‑designed extension can make a significant difference.
I provide a complete service from initial ideas through to Planning and Building Control submissions. My focus is always on practical, well‑considered design that suits your home, your lifestyle and your budget.
Typical extension projects include:
-
Single‑storey rear extensions
-
Side extensions
-
Two‑storey additions
-
Kitchen and dining extensions
-
Sunrooms and garden rooms
If you’re unsure what’s possible, I can advise on options, constraints and the best approach for your property.
Attic Conversions
An attic conversion is a cost‑effective way to create valuable extra space without altering the footprint of your home. Many properties have unused roof space that can be transformed into a bedroom, office, playroom or hobby room.
I’ll assess your roof structure, head height and access to determine what’s achievable, and guide you through the design and approval process.
Common attic conversion outcomes include:
-
Additional bedrooms
-
Home offices
-
Playrooms or hobby rooms
-
Storage solutions integrated into the design
I can advise on structural requirements, fire safety, insulation and all Building Control considerations.

Small changes can make a big difference. Internal alterations can improve flow, create open‑plan spaces, increase natural light or simply make your home work better for everyday life.
Typical alteration projects include:
-
Removing internal walls
-
Creating open‑plan kitchen/living spaces
-
Forming new door openings
-
Reconfiguring layouts
-
Improving accessibility
I’ll advise on structural implications, Building Control requirements and the most practical way to achieve the changes you want.

What Clients Say
Real feedback from homeowners across Northern Ireland
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.”
