"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"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."

"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!"

Structural Engineering questions, answered by experts

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.

It is not recommended to cut or drill into LVL (laminated veneer lumber) beams. As major structural components of a home, their composite structure can be compromised by alterations, which can weaken them and lead to cracking over time. If you must make modifications to an LVL beam, it is crucial to consult a structural engineer or general contractor first. A professional can advise on whether it's safe and provide specifics on the appropriate bit size, depth, and directionality for any necessary drilling.
