Jan 20, 2022 Report
Unprofessional and unorganised customer service. Outdated designs and basic quality of work. Rude and arrogant people to deal with. Would not recommend.

George was recommended by a friend and we have been very impressed with his service. From the outset he was efficient and professional. He has been able to effectively guide us through a CDC/DA process considering our needs, budget etc and making sensible recommendations throughout. He is always happy to chat things through in a professional, yet relaxed manner - which is exactly what we needed undertaking our first renovation. We have also benefited from utilising other providers from George's network, which has been much appreciated. Thank you George.

George was quick, efficient, responsive and really friendly. He designed an addition to our home and talked us through the whole process and came up with a creative way to accomplish what we wanted, as well as putting us in touch with other professionals we needed. I highly recommend his services.

George at GAP Designers was delightful to work with. He was helpful with his advice and obliging in his delivery, extremely prompt in attending to all correspondence and revisions, and great value for money. H
