This has been a stelar experience beginning to end. I contacted Mr. Ghofrani for a structural change involving removal of a kitchen wall. First of all, he was very open about the process and the price. He came to our home, took all the measurements, created the documentation and even applied with the city in our behalf. Any questions we had were answered in a timely manner. I could not have envisioned a smoother and more transparent process. We got the application approved immediately. I would highly recommend Mr. Ghofrani for anyone looking for a structural engineer!

It was a pleasure working with Mohammed and highly recommend GranDesign for any Structral Architectural projects. He was always available and provided assistance with all aspects of the project. He provided drawings for the removal of an interior load bearing wall and City Permit was issued almost immediately. Mohammed displays his professionalism by following up with Contractors ensuring work is being done as specified. I would definitely use him for future projects.

GrandDesign was solicited to design an interior hallway extension to cover the opening above the main entry door. Mohammad’s structural engineering services were reasonably priced and he delivered the permit drawings quickly. As a DIY-er who performed all the work on this project, I relied on his drawing to complete the framing process. The drawings were fairly good but the connections for a diagonal beam were missed and it was not clear how to secure the pieces. Luckily Mohammad kept in touch and provided the missing information. At the end of the framing stage the city required a completion/inspection letter from Mohammad and he again provided all the services needed to finalize this process (at extra cost). I would definitely consider working with Mohammad again for my next project.
GrandDesign company provides excellent services, the best customer service in a very friendly manner. Mohammad is one of the best engineer with all the experience that is needed for any project. he is always available by phone, picks up all the calls and answer every single message, every question you have. Smart thinking , great ideas and solutions from the small details to the big picture. just the best. my project: attached garage to a bungalow, double car, with a roof back sloped, using a valley system for water drainage.

Mohammad is a great structural engineer. The quality of his work is outstanding. I was impressed by the drawings he provided and the city of Pickering was pleased to have such clear and precise drawings. It took 6 weeks to get the building permit approved, which is quiet fast. Apart from some nuances here and there in terms of communication, I would recommend GranDesign. Thank you Mohammad for your hard work and dedication.

Mohammad was very professional to work with. He helped us change our plans to exactly what we wanted and explained everything to us. He was very quick to get the drawings done and respond to us with updates or answer any of our questions.

Mohammad at GranDesign Engineering was very knowledgeable and showed a lot of perseverance in obtaining a special Covered Roof Permit for my client's new Backyard Renovation. During the Covid-19 Pandemic, the permit process was painful and extremely slow, however, Mohammad was able to forge through and got the permit approved in a speedy manner. I will be using GranDesign for permit applications for my company, without hesitation. Thank you, Mohammad!

I called Mohammad on a Saturday afternoon to inquire about his services, and he was at our house to inspect the project we are working on the very next day. He provided drawings with a very quick turn over time, but even more impressive is Mohammad's continued support while we navigate some supply issues. He is always quick to respond with any questions we have via a phone call or a text message, which is greatly appreciated. His pricing is very reasonable and he respected "covid protocols" while in our home. Thanks Mohammad!
