Originally built in 1908, Gaddi Baithak reflects the influence that European architecture had on Nepal at that time. Primarily composed of brick with alternating mud and lime mortar layers, the building includes a double-height great hall with timber trusses, wood-framed ceilings and floors and minimal use of steel for connections above the ceiling. Two box-like appendages on either end of the hall include mezzanines. The south face of the building features a terrace with six sets of double columns. The building had been little used over the past 50 years and poorly maintained.
