About Us

John Winterburn and Nancy Van Natta first collaborated on the design build of Nancy’s house in Soquel. The process of building that house was so enjoyable for both that they’ve decided to combine forces into a Design Build collaboration. 

Nancy says:

“John is a great problem-solver.  He figures out the smoothest way to accomplish something and is always able to keep projects on schedule and on budget. His team is quick and efficient and they’re great people who are known and respected  for their many years of great work in Santa Cruz.”


John says:

“Nancy makes my job easier with clear drawings for all the details and we collaborate easily on design-build solutions.  She’s knowledgeable about construction and that’s reflected in her design work.  She’s also a former San Francisco designer who brings a lot of new ideas and expertise to the table.
