41 West Main Street, Uphall

41 West Main Street in Uphall is a single-storey, four-bay, T-plan house built around 1886. It is half-timbered and boarded, and is believed to have been a former exhibition pavilion, possibly from the Edinburgh International Exhibition of 1886. The southern and western elevations feature a herringbone arrangement of boarding. The house has prominent timber bracketed gables on each elevation, with pierced timber gableheads, deep overhanging eaves, and timber arcading on the garden front facing south.

On the northern (principal) elevation, there is a wide central ground floor window framed by a decorative timber arch at the upper half. To the left, there is a timber panel door with a round-arched fanlight, and bipartite windows in the outer bays, with the right window blocked by boarded timber.

The western (side) elevation also has a wide central ground floor window. The southern (garden front) elevation features an advanced, three-bay, gabled and arcaded central section with later double doors and large flanking windows that have been enlarged. The outer bays also have large windows.

The eastern elevation adjoins No. 39 West Main Street. The house has timber and plastic windows, pitched roofs covered with grey slates, central stacks, and three octagonal clay cans.
