This is a designed, generic interpretation of the real request, not a surveyed building or an attributed historical tea house. Sweeping eaves, an arched crossing and a tiered stone lantern carry recognition; all dimensions, joinery, landscaping and tea service are inferred or decorative. A shoji slides open; water, tea steam and lantern light supply quiet life."
