"We have had the pleasure of working with **** since 2011, and over the years he has completed several projects for us that have spanned large complex remodels, new construction, and major structural repairs. The reason we have **** and Johnson Custom Builders as our sole resource for construction projects is due to his process for comprehensive planning and estimation, project management, attention to detail, project schedule integrity, excellent subcontractors, quality of outcome, his personal involvement in every detail-- and that he is incredibly pleasant to work with! We have dealt with many contractors and custom builders over the years, and **** and Johnson Custom Builders are the hands down the best."

"This review is long overdue.  We can?t really express
how happy we are with our new house that Char designed.  We hired Char to
design our remodel in 2013/2014.  When I say remodel, that is a bit of an
understatement, as we took a 700 square foot house to approximately 1,900
square feet, which included adding a basement.  It is essentially a new
home, and we couldn?t be more happy with it.  We did the majority of the
work ourselves, which is one reason it?s taken us this long to sit down and
write a review.  Although having a baby 1 month before the excavators came
added a bit to the complexity of things...  The project pushed us to our
limits, and a little beyond at times, but it has all been worth it.  Our 2
year old son absolutely loves to run around and scoot across our big long
hardwood floors on his little scooter.  There is quite a runway now, and
he definitely takes advantage of it.
But back to the review.  We knew the basic idea of what
we wanted, but we needed an architect to draw up the plans.  We wanted to
hire someone local, and Char was great.  Char really knows the code
requirements which helped a lot getting the plans through the permitting
process.  We drafted up a general floor plan before hiring Char, and she
provided a lot of good ideas and helped us refine the design to work more
efficiently in the given space.  This turned out to be a lot more
important than I thought because it?s hard to visualize how a space will flow
and function from a simple floor plan.  Char also knows a lot of
professionals in the industry, which is great when it comes to engineering calculations,
truss design, etc.    
We really like the neighborhood we?re in, and it was
important for us that our new space match the character of the original
house.  You see a lot of remodeled houses that are cute in front, with a
big ugly 2-story box sticking up in the back.  We wanted to avoid this and
worked hard to make the addition look like it was always a part of the
house.  We also wanted the house to retain its ?small? appearance from the
front, and we didn?t want to use up all of our backyard either.  We ended
up with a perfect house.  Our neighbor across the street who was born
there in the late 1940?s told us he can?t even remember what the house used to
look like - he said it really just looks like it?s always been there (and it?s
only been 2 years). 
I would definitely recommend hiring Char if you need an
architect or design help.  Beyond her architectural skills, she is very
personable and easy to work with.  She came out to our house many times to
review drawings with us, go over edits, and discuss various ideas.  She
was very accommodating, and even helped us get the plans through the permitting
process.  Thank you so much Char, we really love our new house, and
couldn?t have done it without your help.

"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."

"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."

"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."

Structural Engineering questions, answered by experts

Combining structural engineering projects with upgrades like insulation, plumbing, or electrical work in Seattle can minimize disruption and maximize efficiency. For example, if you’re opening walls for seismic retrofitting, it’s a great time to update wiring or add vapor barriers. Coordinating projects during Seattle’s dry season helps avoid weather delays, and bundling improvements can streamline the permit process and reduce the overall construction timeline.

Helpful?

Your Seattle home may need structural engineering if it’s older, especially pre-1970s, or located in areas with soft soils or steep grades. Signs like uneven floors, gaps around windows, or visible foundation cracks often indicate underlying issues. Homes in neighborhoods prone to landslides or with a history of flooding should be professionally evaluated, particularly if you’re planning a remodel or have noticed new settling after heavy rainfall.

Helpful?

Seattle homeowners should factor in the city’s variable soil types, high groundwater, and risk of earthquakes when planning structural engineering work. Properties in neighborhoods with steep slopes or near bodies of water may require specialized drainage solutions. Additionally, historic districts may have unique permitting requirements. Scheduling projects during the summer helps avoid rain-related delays, and working with local experts ensures your plans suit Seattle’s distinct geology.

Helpful?

Completing structural engineering projects in Seattle offers immediate benefits like improved home safety and better protection against earthquakes and heavy storms. In the short term, you may see increased property value and easier insurance approval. Over time, these upgrades help prevent major structural damage, lower maintenance needs, and ensure your home remains compliant with evolving building codes, contributing to a safer, more resilient neighborhood.

Helpful?

In Seattle, structural engineering maintenance should include scheduled foundation inspections, especially for homes in neighborhoods like Queen Anne or Magnolia with steep slopes. Annual checks of seismic retrofitting hardware and regular assessments of crawl spaces for moisture intrusion are vital due to the region’s wet climate. Pay close attention to wood framing in basements and retaining walls, as these areas are especially vulnerable to rot, shifting soils, and water seepage.
