Shed & Co. is a family business based in Sonoma and Walnut Creek, California. Julie Drummond and Jessica Willemsen have been working together for five years.

We pride ourselves in our ability to learn how our clients like to live in their home and then figure out how to make the house function better for them. With our backgrounds and experience in Architecture and Interior Design, as well as our experience raising kids, we know the importance of designing a house to work for families as they grow and change. We love problem solving and challenging ourselves to help our clients see all the opportunities in their home.


Our projects range from small scale remodels of existing homes and rooms to large scale additions. We help our clients master plan their properties and create phased projects, as well as design kitchens and bathrooms.


Our services are tailored to individual needs and can include:

  • Pre design and Planning

  • Master Planning

  • As-Built Drawings

  • Schematic Design Options

  • Finish and Furnishing Selections

  • Custom Furniture

  • Permit and Construction Drawings

  • Coordination with Engineers, Contractors and consultants

  • Submittals to city agencies for building permit

  • Project Management
