Onju Updegrave is an architect specializing in new and remodel single family residences. Projects in custom residential architecture span the San Francisco Bay Area with a focus in central and West Marin County. A rich diversity of residential projects include rural residential projects on large parcels with private water and septic systems, projects incorporating green practices such as solar technology, and projects with very tight space and budget constraints.

## Community Q&A

**Q: Can you share the dimensions of the room?** *(in Photo Questions)*

A: It is 5' wide by 8.5' long. We fit this into a very tight space.

**Q: what kind of stone is this?** *(in Photo Questions)*

A: This is a cultured stone (manufactured stone) product, not natural stone. The project was built in 2007, I'm not sure exactly what the product was. But I believe it be referred to as Country Ledgestone product.
