When I am in the US, I am based out of Leesburg, VA (in the greater Washington, DC area).
I do a lot of custom design, building, renovation, site supervision, consultation, and instruction around the region.

I also can be hired to do consulting, educating, site supervision, or other projects in other areas in the world if I think the project might be a good fit, so reach out and let me know what the project might be and I can let you know if it might be possible.
In some cases, I can also be hired to do consultations, instruction, or design work online for people in other regions.
