"We hired Char to help us design an addition to our home in Burien, WA. Our addition adds a 300 sq. ft master suite to our 1100 sq. ft house. Char built our trust quickly. She listened carefully to our concerns, and used her own creativity to make huge improvements to our original plans. Our project wouldn’t have looked the same without her input. Char incorporated very specific requests from us concerning noise reduction, and went above and beyond to research many solutions for us to choose from. Char communicated her schedule clearly, we always knew exactly what she was working on, her deliverables, and what we would discuss in our next meeting. We never had a meeting that wasn’t useful. Char helped us navigate the Burien permit process, making sure the drawing package was complete enough to pass the first time. She reached out to specific city officials ahead of time to anticipate any issues before permit submittal. Char created very detailed drawings and has exceptional drafting skills. She added more detail than required at every stage of the design to help us make critical decisions earlier in the process. Our hired GC complimented Char’s drawing package when we put it out for bid, saying it was better than many that he’s seen. We also hired Char to meet with contractors and review estimates. She was able to help us navigate what was a reasonable price and weed out any weird or misleading estimates. In summary, Char has been a fantastic resource for us and has helped make our first major home improvement project much less daunting."

"I used Triple V as the Project Engineer for a garage conversion to single family residence for my son’s family. Vic not only did the engineering for us, he also did the structural drawings we submitted to the county as part of our permit package. He delivered the plans promptly, and worked collaboratively with us to resolve issues we identified and revise the drawings accordingly. The county building department approved the plans and issued the permit. During the project construction Vic patiently responded to questions from us (we’re DIY’ers, not professional builders) and offered/provided certifications to revisions we jointly agreed to. Overall, Triple V provided what was promised at an outstanding value."

"I had the pleasure of working with Bryson on a recent project, and I couldn’t be more impressed with their work. From start to finish, Bryson demonstrated extensive knowledge and expertise in structural engineering. They took the time to understand the project’s unique needs and provided clear, practical solutions that ensured everything was both safe and efficient. One of the standout qualities was their excellent communication. They kept me informed at every stage, answering questions promptly and offering advice when needed. Even when challenges arose, Bryson approached them with professionalism and a problem-solving mindset, ensuring that the project stayed on track. The quality of the work was exceptional. Every detail was carefully considered, and I felt confident in the structural integrity of the design. Bryson truly went above and beyond, offering both technical skill and a genuine commitment to the project’s success. Thank you and I look forward to working with you again."

"Josh has always been prompt and communicative with every interaction we've had. I initially got in touch with him about new construction design questions, and when we discovered that our current home porch posts had rotted through due to faulty design by the original home designer, Josh jumped into action. He had his engineer and construction crew to our door within 24 hours to take a look and put together a plan. He took my design ideas and brought them to life. He was transparent about all parts of the cost (to include his profit), and gave us to option to lower the cost by hauling away debris and painting the porch (which we were more than willing to do). Any delays with the work were met with a phone call and followup email if he didn't get through to either my husband or I immediately, and the construction crew did very high quality work. We were beyond pleased with his customer service! We will definitely use Revival Home Designs in the future when we decide to build our forever home."

"Ward Engineering began working with Jared of Cornerstone Home Designs approximately 3 years ago to perform residential design work using Chief Architect design software. I find Jared to be the most capable Chief Architect designer I have ever worked with. Jared is very efficient and thorough at developing the residential Chief Architect models. In addition to being competent, Jared makes himself available to provide personal 1-on-1 training over the internet, which has been a huge blessing to our company and clients."

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.

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

Most load-bearing walls are exterior, though they can also be interior.
