About GT Building Design

With over 35 years experience in Architecture I established GT Building Design in 2004 to specialise in obtaining Planning Permission and Building Control Approval for homeowners. I guarantee you a quality service, value for money, my expertise and a reliable professional service. My office is based in the seaside town of Donaghadee, County Down and I provide an architectural design service throughout Northern Ireland.


"Glenn provided us with a fantastic service, thanks to his expertise and efficiency we had planning permission granted within a matter of weeks after submitting plans for our two story side extension & renovation. It was a pleasure to work with Glenn and we would strongly recommend GT Building Design. Thank you very much."
