Description
Grail Retreat is a row of four houses, numbered 7A to 10A, located on Heol Tan-y-bryn in Abergynolwyn. Built from slate rubble with slate roofs, these two-storey houses feature attics and cellars, following a double-depth plan with two and three bays. The doors have three raised-moulded panels set in staff-moulded frames, topped with deep fanlights. The ground and first floors have twelve-paned sash windows, while the attic at the rear has six-pane windows. All openings are adorned with deep stone lintels, and the chimney stacks with outsetting heads are positioned on the party walls.
The house at the southwest end of the row has three window bays and retains its original three-panelled door, although the fanlight above features an arch. It has twelve-paned horned sash windows, but a former opening, likely a shop window, to the right of the door has been replaced with a tripartite uPVC window. There are also later extensions to the rear and three roof lights.
