Coachhouse immediately to south-west of Hatfield House Farmhouse

The building is a coachhouse located immediately to the south-west of Hatfield House Farmhouse, dated 1789. It is constructed of red brick in English garden wall bond, with ashlar dressings and stone slate eaves courses beneath a pantile roof. The coachhouse has two storeys and features three bays on the west side, with the central bay set forward. It has large quoins, and the quoined central bay includes large boarded doors beneath a round arch, which has an impost band and keystone. The impost band extends to the left over garage doors set in a recessed round-arched panel with a keystone, and a similar panel is found in the third bay. An eaves band runs across the gabled central bay, which has a ledge to a keyed lunette in the tympanum. The gable features shaped kneelers, gable copings, and ball finials with bands on the left and at each side of the gable.

At the rear, there is a central basket archway that has been bricked up, along with a bricked-up lunette above it. Other openings include a door to the first floor on the right, flanked by slatted casements, and bricked-up pitching holes on the left. On the right return, there are two boarded ground-floor openings flanking a boarded pitching hole, with another in the gable. The numerals of the date 1789 are visible as tie-rod ends. The left return shows tie-rod ends with the initials 'W.G.' The coachhouse was formerly a stable block serving Hatfield House, which has since been demolished, and the initials belong to William Gossip, who married into the Hatfield family.
