Slate & Sumac began as a two-person design practice and grew into a small design and build studio.
We take on a limited number of projects each season so the people who design your space are the people who build it.

How we work
The same team designs and builds, so what you approve is what you get.

Every decision was explained, every date was kept, and the garden looks better every month.
We spend every evening out there now. Worth every dollar.
