tanya the designer of mango designs is amazing. she is young, very forward thinking, and designed an aesthetically pleasing , light filled, original additional to our house. our house is situated on a pie lot and the city mandates that the new addition top floor can only be 60 percent of the allowable main floor. even on such vancouver city restrictions she managed to design enough bedrooms and bathrooms to meet our growing family and managed to give us an amazing roof deck. very happy with her creativity and service.
