20 Royal Terrace, Linlithgow

20 Royal Terrace in Linlithgow is a villa built in the later 19th century. It is a single storey and attic structure with three bays, featuring a symmetrical gabled design on a corner site. The exterior is made of cream stugged sandstone rubble, which is squared and snecked, with ashlar dressings on the west elevation. Notable architectural details include a base course, chamfered reveals around the windows, brattishing, overhanging eaves, and decorated bargeboards with finials on the gables.

On the west (entrance) elevation, there is a projecting gabled porch at the center. The window on the west face is framed with banded ashlar, and there is a fanlit door on the left return and a window on the right return. The flanking bays feature canted windows with cornices and slate roofs adorned with brattishing. A gabled dormer is located at the center, with dormer-headed windows in the outer bays.

The north (side) elevation has a gabled design with a window at the ground level in the center and another window above it, as well as a window at the far right on the first floor.

The east (rear) elevation consists of three bays, with a stair window at the center and a smaller window below it. The flanking bays have windows at ground level and dormer-headed windows above, featuring plain bargeboards.

This wing has a plain bargeboard, a window on the left (west) return, and three bays on the right return with a window in the center, a doorway to the right, and a shed door to the left.

The villa features plate glass sash and case windows in the canted areas, fixed-pane windows with borders in the porch and stair areas, lying-pane windows on the east return of the wing, and 4-pane sash and case windows elsewhere.
