"We started out looking for an architect/designer, and met the owner of Tseranos Construction, Sterg, in the process. He referred us to a design architect, which we used, and we ended up then hiring Tseranos Construction as our general contractor. Sterg was really great to work with. He found ways to keep costs down while doing everything that we wanted to have done. In the end, the garage construction project took about 5 months, but we are thrilled with the results. Would hire Sterg again for future projects."

"Evolution design worked with me on designing and addition for a 100 and 5 year old house. We worked on the dimensions of the addition Plus the materials. Evolution understood the local zoning which was amazing that they knew that. We have not started construction. And evolution can help pull the permits and I'm considering them for that as well. All in all it was a long project but it was done efficiently, working with several of the staff an the departments."

"Vista installed new vinyl siding on our house and I couldn't be happier with the result. Our house looks brand new and I love the color. The communication was excellent! Every step of the project was very organized and I loved how Keith and Brian checked in every few days. The work crew was very repectful of our propery and the quality quality of work is amazing. Overall it was a refreshing, seamless experience. I would highly recommend them."

Structural Engineering questions, answered by experts

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

Whether you’re building a new home or building an extension on your existing property, you will likely need both a structural engineer and an architect. A structural engineer will determine what loads your foundation and framing can safely handle, and an architect will draw plans according to those structural calculations to simplify the building process. You can start by contacting a structural engineer near you, as many work alongside architects and can get all of the prep work done at once.

Their expertise in identifying potential problems early and implementing durable solutions safeguards your home’s integrity.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems.
