"Short version: If youâ re looking for a very very knowledgeable person who will take all your wants and concerns into consideration, your search stops here with Lynn at Kesselman Architectural Design. He demonstrated to me that he is the best person for the job! Long version: I spent hours and hours looking at house plans. I found none had what I wanted, and there was one plan I kept coming back to that just wasnâ t quite right. It needed drastic changes, so I began my search on how to get the plans modified to meet my wants. I learned quickly that it is not just a â simpleâ thing to move a wall, or just â make the house smallerâ . In my search, I came across Kesselman Architectural Design. I contacted Lynn and we setup an appointment. I showed him the house I kinda sorta liked and the changes that I would want. After another week, we talked about getting the work done and I showed up at his office the next day and he had the floor layout already done! It was very impressive. After we shook hands and the work started, it was an iterative process. Lynn would make progress, send me updates, I requested changes, heâ d make them, send the drawings back. Lynn made it so smooth and since he captured my vision early on, I rarely had feedback for something that I didnâ t like. It was more of â can you add more outlets and a light here?â kind of thing. I can say with 100% certainty that it was worth it. When I compared my drawings to a house plan bought online by a co-worker, I immediately knew the time and money invested was worthwhile. The details on Lynnâ s drawings far exceed the â store boughtâ plans and will pay dividends in the long run. Plus, these plans are exactly what I wanted! I did not have to settle. I recommend Kesselman Architectural Design for any architectural projects you have. Thanks Lynn! It was GREAT working with you!"

"Clear specific recommendations to stabilize and correct sinking foundation & leaning walls on my 100 year old solid brick garage. Will implement recommendations. Although engineering report was promised within 7 to 10 days of inspection, it was received in 25 days. Worth the wait, great overall experience."

"Tim is amazing. I was days from closing on a house when the underwriter decided a structural engineering report was required so I called and spoke with Tim on a Wednesday evening, met with him Thursday morning and had a report in my hand by Thursday at noon, less than 24hr turnaround! Needless to say Tim really helped me out and was very courteous, knowledgeable and professional. He will always be my go-to structural engineer."

"The estimate was provided the same day they came to look at the roof.  The estimate was detailed and easy to read.  Gino kept me informed of all the steps and the work was completed on time.  Very professional.

"I had a fantastic experience working with this drafting firm. From the very first phone call, Kirsten?our drafting consultant? was clear, professional, and incredibly helpful. She explained the entire process in detail and made sure all of my questions were answered up front, which gave me immediate confidence in the team. This firm partnered with engineers and architects to get the best quote for me on a stamp for my plans after they did an exceptional job on drawing the prints that met all the requirements for permitting. Their coordination and attention to detail made the process very simple on my end. If you are looking for a highly capable drafting firm that knows how to get things done right, I highly recommend them!"
