Client Testimonials

Letdel  has done a great job solving structural problems creatively and the drawings have been amazing. They are responsive in getting the work done efficiently and answering my questions. They were able to get the work started within days. Much faster than anyone else we tried to hire.

Erfan and his team at Letdel have designed and built a garage in line with our expectations and has made the process very smooth for us. We enjoyed their timely delivery of the deliverables and their professional attitude that made the entire process very easy and clean for us.

It was a pleasure working with Erfan. His details on features and notes on prints where clear and concise. He was always available for discussion of issues that arose. I would recommend him to friends and family. He has now become our top referral for architectural work. He also helped get permits without any hassle or problems, of any kind.
