Building at former Powder Works, Hendre Quarry

The building at the former Powder Works in Hendre Quarry is a large rectangular, two-storey structure with seven bays, built from rubble stone and featuring large quoins beneath a hipped corrugated-iron roof. It has round-arched openings on both the front and rear, with the ground floor arches being taller. The arches are adorned with red brick dressings. The main entrance is located on the south-facing central bay, with an additional entrance in the second bay from the left. Some openings have been infilled with rubble stone, including the central upper opening and the second from the right on the front elevation. There are remnants of 2-light wooden window frames in some of the upper storey openings, along with corrugated iron sheeting beneath the arches. The building also has tie bars, and the east and west ends do not feature any external openings.

Inside, the floor is slightly raised, and some brick paving remains. The building is open to the roof, showcasing light King-post roof trusses. The first floor has been removed, but infilled beam sockets along the sides and joists at the ends indicate its former position. A low stone wall separates the two bays at the west end from the remaining five bays. This smaller area contains stone side benches, and the rear openings are blocked with stone, except for the top right. The west end features a small blind opening with a segmental head on the lower storey. The east end has tall blind arches on each storey, which are infilled with red brick above and stone below. The arch above contains recesses that may have been used for machinery, along with a further brick-lined socket to its right.
