Commitment to excellent service and professional knowledge are key factors for the success of Sun Architecture. Solving the budget, functional, and meeting regulation constrains requires the skills and talents of our experienced team of professionals. The design team of Sun Architecture believes that the interaction between Client and Architect can produce buildings that withstand the changes of fashion and time. The best projects emerge from the cues of the site, sun and climate. A complete design considers both the interior and exterior of the building as a totally integrated effort. Our team members interact continuously from concept to construction. Sun Architecture produces clear, understandable presentations of project concepts and design. We bring projects to fruition with a clear, detailed set of construction documents. Our commitment continues through bidding and construction administration, until the project is complete.

"Just me George Sun a month ago to discuss what we (wife/I) wanted to do to our existing resident. So far is very courteous and knowlegeable in all aspect of his job. But rate someone at this time is impossible. Please resubmit this at latter time. Will complete this when the job is done Thanks"

Mark Brand Architecture's award-winning architecture and interior design studio balance high design with practicality, combining understated elegance with elements of drama. Our goal is to exceed our clients' expectations by maintaining a creative, enjoyable and efficient relationship between the owner, architect and contractor from the beginning of design through completion of construction. No job is to big for us, and we always deliver professionalism and excellent work to all of our clients. For an architect you can trust, give us a call today!

"Mark Brand asked all of the right questions and worked tirelessly with the city permit department to make sure everything we wanted to do would be approved. Beyond being amazing on the phone with the city, his design fit with our mid-century home and anyone who has seen it is amazed at the transformation of our small back yard. We started this project with Mark in 2019, long before COVID-19, and completed the major construction in October of 2020. The actual construction began in May 2020 with demo, to completion in October 2020. Mark and his staff were with us through the entire process, communicating with our Contractor and Pool installer and keeping everyone in the loop and on track. I had never worked with an architect before, and feel grateful that my first experience was with Mark Brand and his team. Fees are explained up front, and although the fees were a healthy part of our budget, I know I got what I paid for! Communication with email and phone calls, as well as site visits were always timely, with any issues explained and problems worked through and resolved to avoid delays."

FAQs for custom home building projects in Mill Valley, CA

One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.

Typically, it’s more affordable to buy an existing home than it is to build a new one. New construction loan interest rates tend to be higher than interest rates for traditional mortgages. Additionally, the cost of materials is likely higher when building a new home than it was when an existing home was built (unless it’s a very new one). You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity. 

The average price per square foot to build a house is about $150 per square foot. Overall, the cost to build a house ranges anywhere from $100 to $500 per square foot, depending on where you build. The primary cost factors include location, size, and style of house you build.

The average cost to hire an architect for your home project ranges between $2,200 and $10,500. However, depending on location and project type, you might end up paying as little as $600 or as much as $45,000 or more. For example, the average cost of hiring an architect in North Carolina is between $1,800 and $2,000, but in California, that price tag jumps to $3,600 to $15,200

The price you pay for your architect also depends on their experience level. For example, a principal architect, the firm's owner, typically charges $150 to $250 per hour. However, an intern architect with three to five years of experience usually only charges $45 per hour. 

Knowing if you need an architect for your project can be tricky, especially if you've never worked with one before. In general, small remodeling projects like replacing fixtures typically don't require the expertise of an architect. However, larger projects, like moving walls or adding an addition to your home, should include an architect to ensure the project is structurally sound.
