We engaged Atlas Designs to assist with a residential alteration to an existing building (floor plan changes, permit submission). From start to finish, the team was highly professional, responsive, and knowledgeable about municipal permit requirements. Thanks to their expertise, we successfully secured our building permit without any major delays or issues. We wholeheartedly recommend Atlas Designs for any residential permit/alteration project and also architectural designs. There are amazing.Posted on Google![]()

I had an excellent experience working with Atlas Designs to obtain a building permit. George was always responsive, patient and willing to help. He listened to my ideas, but also brought his own, better ones. He revised the drawings when I asked to change them and answered all my questions repeatedly. He completed his work on time and always communicated clearly and promptly. I highly recommend working with George!
