Junction House at Pontymoile Canal Basin, Monmouthshire and Brecon Canal

Junction House at Pontymoile Canal Basin is a canal toll house dating from the 19th century. It features roughcast walls and is topped with Welsh slate roof cladding. The building has a distinctive bowed two-storey front facing the canal, with a lower wing that has a gabled roof set back at right angles to the south-west. Both sections consist of only one room each.

The front section has a half cone roof and a first-floor sash window without glazing bars. There is a modern single-storey gabled porch that projects forward, which includes a small window opening on each side wall at ground level. A stack is located on the rear gable of the wing. The north-east side of this wing has a panelled door with a shallow overlight on the ground floor and a window on the first floor. The south-west side features a sash window with glazing bars on the ground floor and a blocked window opening on the first floor. The canal-facing elevation of the adjoining south-west wing includes a window opening, and there are additional openings at a lower level in the south-west gable end.

Inside, the toll house is said to have panelled doors, although the rooms are likely to be very small. This toll house bears a close resemblance to Turnpike tollhouses from the same period, but it offers slightly better accommodation than some of its counterparts.
