If I have helped you with a project I would be delighted if you would take a little time to provide a review. It's important that others considering improvements to their homes have confidence in the architectural services I provide and confidence in me. Thank you, very much appreciated. Glenn


"We consulted Glenn regarding a loft conversion to an en suite bathroom. Our experience of working with him has been first rate from start to finish. Firstly, his personal traits. Importantly he is reliable – when he says he will visit, call you or meet some deadline, he fulfils whatever commitment he has made. He is affable and enthusiastic, and sees solutions rather than problems.
Secondly, he is experienced and professional. He took us through all the stages needed to complete our project, made useful and practical suggestions we hadn’t considered, and incorporated what we wanted into the design. This resulted in the quick production of drawings and specifications which he then progressed through Building Control approval.
Unfortunately, COVID 19 has delayed building work beginning. However, we have no doubt Glenn will continue to advise and assist us whenever we can revisit the project."

William Brown, Belfast

"Glenn managed the Design, Planning Consent and outline Building Control Approval for a beach front cottage extension at Ballywalter. I found him highly professional, knowledgeable and efficient with a great attention to detail. At the outset he defined the stages (and associated costs) of the project and these proved to be entirely 'on the button'. I would have no hesitation in recommending Glenn to any prospective client.

Replacement Dwellings

"Embarking on any building project can be a very daunting task, and when we decided to knock down our then holiday home to build our home of the future we set about finding the right partner to ensure we got things right. We found Glenn’s details in a local ad, and arranged to meet him. From the outset Glenn impressed us with his knowledge, professional approach and enthusiasm for our project. Having reviewed what work he had done, we were confident we had found the right man for our job. We appointed Glenn, and 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 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.

Single storey extension

"We are really loving the new extension to our kitchen and living area and for the space that it has created for us to host our children and grandchildren. It has been a pleasure to work with Glenn.  We so appreciated his "hands-on" approach and all his guidance and expertise throughout the entire project."

Extension in Belfast

Our experience of adding an extension to our house was a very positive one and having Glenn guide us through the planning process was so helpful. From the initial visit to our home and drawing up plans right through to that final call to tell us that our planning application was successful Glenn's professional, friendly and methodical approach was very reassuring. His expertise in dealing with planning department officials and completion of the myriad forms removed a lot of pressure and allowed us to focus on other aspects of the job. We were delighted with the end result and would recommend him to anyone who is looking for a quality service from start to finish. We are on the lookout for a new project and are looking forward to working with Glenn again in the near future!

“Dear Glenn, thank you for forwarding on all the relevant documents which I will keep safe. I appreciate so much all the expert advice you have given to me, and all the consideration and patience! You are an angel, yours sincerely Sylvia .”

Sylvia Higgins, Largymore Drive, Lisburn

Extension in Newtownards

"From our first meeting and then subsequent meetings with Glenn we felt comfortable with him as our Architect. This was because he listened to our suggestions and incorporated them into his initial drawings. Drawing on his expertise, he came up with several ideas we would not have considered. He guided us through the planning application and subsequent building control. Glenn was always friendly, open and someone we could trust to "keep us right" Now that all the work is finished, we are so glad we used GT Building Design"

David and Pauline Murdoch, Trasnagh Drive, Newtownards. 

"Glenn did a first rate job. He was attentive and prompt. The drawings for our extension were meticulous and praised by the City Council. He left nothing out and his service was excellent throughout the whole process. I have no hesitation in recommending him to you"

Paul Reid, Belfast

"Glenn was very professional, understanding of what we needed and patient with us from start to finish on our garage conversion project. We got through planning and building control approval extremely quickly which was great with no hiccups. I would gladly recommend him to anyone based on our experience. Thanks again Glenn"

Aaron Henderson, Newtownards

"Glenn has done design work for me on a house extension and in support of retrospective planning and building control applications. He brings a degree of expertise that makes the process straight forward and always delivers efficiently and on time. Easy to work with too, which is always a bonus. Highly recommended"

Will Brown, Donaghadee

"Hi Glenn. This is just a little note to thank you for the professional, prompt and efficient way that you have designed the plans for my new garage. I am really pleased with the drawings and looking forward to getting the work started as soon as possible! It has been a pleasure dealing with you and I will be happy to recommend your services in the future. Regards Bryan"

Bryan Halpin, Springwell Road, Bangor. 

During July 2014, we decided to extend instead of move house, and hired Glenn to provide the drawings. What an excellent job Glenn did for us. He was fast, efficient, and kept us updated each step of the process. He took all the stress out of the process by notifying the neighbours, notifying the Planning Office, and worked closely with our builder. He supplied a full written quotation, with a clear itemised price of each stage, and forwarded all important documentation quickly. Planning Service rejected the first set of drawings, but Glenn phoned us immediately to discuss alternatives, which were passed the second time, and nearly a year to when we started the application, we are delighted with the end result. We definitely recommend Glenn for his professionalism and expertise.

Campbell and Maureen Beers, Queensbury Park, Bangor. 

"We engaged Glenn to make substantial amendments to plans for refurbishing the ground floor of our house on the recommendation of our builder. From the outset, we found Glenn to be extremely professional, reliable, easy to work with, and always willing and able to answer any queries that we might have. Following an initial briefing, Glenn produced preliminary drawings within a quick time-frame that delivered in terms of meeting our needs, wants and budget. Glenn listened carefully to what we wanted and worked hard to ensure that this was feasible. Glenn dealt with all of our queries promptly, efficiently and, equally importantly, courteously. All meetings took place at our house and at times that were convenient for us. Things happened when they were supposed to happen, which made the whole process and, incidentally, our lives much easier! All in all, we are very happy with the service supplied by Glenn and have no hesitation in recommending GT Building Design to future clients."
