David Marshal Lodge And Indicator, Aberfoyle

David Marshal Lodge and Indicator, located in Aberfoyle, was originally built as a modest tea room and pavilion designed by James Shearer and Annand between 1958 and 1960. In 1978, a timber and glazed extension was added to the north by Ian G Lindsay and Partners. The Lodge now serves as a visitor centre for the Forestry Commission Scotland in the Queen Elizabeth Forest Park. It is situated on a hill overlooking Aberfoyle to the south and features a roughly Y-shaped plan, exemplifying post-war Modernist architecture with an unusual layout.

The original building is constructed from distinctive drystone rubble Lake District slate and has a simple three-wing radial plan, highlighted by a two-storey pyramid-roofed tower at the center. The flat roofs of the radial wings extend on the east, south, and west elevations, supported by twin-tube concrete columns, creating a sheltered viewing platform. The entrance is located on the west side of the north wing within a recessed bay, currently screened by a timber and glazed wall forming an outer vestibule. The doorway is framed by polished, round-ended concrete columns with flanking windows. The windows are timber-framed, featuring two smaller panes, one of which opens, above a larger pane below.

The 1978 addition extends from the end of the north wing, utilizing the sloping ground to create a two-storey heptagonal structure, with the glazed upper storey jettied out on timber columns over the service accommodation below.

The interior of the Lodge was originally simple, and little of its character remains.

To the west of the main building is the Lodge House, an L-shaped, flat-roofed single-storey building, also constructed between 1958 and 1960 by James Shearer and Annand, using the same Lake District masonry.
