Leeson House

Leeson House is a country house that now serves as a Field Study Centre. The original section dates back to the 17th century and is currently used as kitchens and other facilities. The main section was added in the early 19th century and enlarged in the mid-19th century. The building features stone walls, some of which are plastered, and slate roofs with parapets and coped gables on the main section. The house has an irregular plan and is two storeys high with an attic. The main block is designed in the early Gothic Revival style.

The garden front includes projecting bays at each end and a gabled dormer in the center. Octagonal finials are present at the springing and apex of the gables. On the ground floor, the left gable has a pair of French doors with a hoodmould, while the right gable features a sash window with glazing bars, also under a hoodmould. There are two similar windows in the central section. The first floor has a range of four similar windows, and at the attic level, each gable and the central dormer has a casement window with glazing bars, all under hoodmoulds.

At the right end of the main block, there is a slightly lower wing with exposed stone walls and a slate roof, which also has a parapet and coped gables. This wing is two storeys high and includes a part-glazed door. The ground floor has one sash window with glazing bars, and there is a similar window on the first floor located in a gabled dormer with brick dressings. At the left end, there is a Gothic timber conservatory, and behind it, a projecting porch with exposed stone walls. The entrance is located in the return wall and features a four-centred arch flanked by octagonal turrets.

At the rear of the main block is the original 17th-century house, although no early features are visible. There is also a large later 19th-century addition that is partly flat-roofed and has been altered in the 20th century. Inside, the entrance hall boasts a plaster vault and archways with ogee-shaped timber surrounds. The main staircase features Gothic-style balustrading. Several ground floor rooms contain imported 17th-century carved woodwork, likely Flemish, including one fireplace surround dated 1664.
