Jameson named the house Graticule, after the network of latitude
and longitude lines used for measurement on a map. “It’s an
optimized architecture created specifically for the site,” he says.

On the two square footprints, Jameson placed a pair of simple rectangular
volumes. A three-story cube houses
a two-car garage, a master suite above
that, and a media room and terrace on
top. On the other footprint, Jameson
wanted to stretch out horizontally,
so he sought an exception from county
officials. “We negotiated a deal that
by not digging a new foundation—but
instead creating a delicate incision into
the earth—we could build over and past
the RPA line,” he says. He gained a good
12 feet in the process, which became a
double-height living room cantilevered
out into the woods. Where the breezeway once stood, a glass foyer now links
the main house and the tower.
Although Jameson favors sleek, high-
end minimalism, he likes to incorporate
mass-produced materials more often
found in industrial applications. The
Great Falls house includes glass sheets
as railings, maple planks for a ziggurat-
like box stairway, storefront glazing
for nearly all the windows, and “sticks”
of commercial-grade aluminum for
mullions. “We designed a sophisticated
building using unsophisticated parts,”
Jameson says.
