"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."
