"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!"
