Chapel In The Garden And To The North East Of Church House

The Chapel in the garden and to the north-east of Church House is a small 15th-century monastic building made of stone rubble with a tiled roof. It features a stoup and was once converted into a stable, retaining a manger from that time. The building is L-shaped, with the south wing having two storeys and the west wing having one storey. The ground floor is constructed of Pulborough sandstone ashlar, while the upper part of the south wing has weather-boarding and visible timber-framing at the east and west ends, with plaster infilling. The roof is a combination of Horsham slabs and tiles, built using king post construction.

The entrance for vehicles was located in the centre of the west wing, which originally served as the bar. This entrance features a large stone four-centred arch that is now blocked on both sides, with red brick on the west and stone on the east. To the south of this archway on the east face of the west wing, there are three four-centred stone doorways with deeply moulded jambs and lintels, and traces of a dripstone above; two of these doorways are now blocked with red brick. The west wing also has two blocked cinquefoil lancets and buttresses at the angles of its north front.

The south wing, which served as stables and possibly sleeping accommodation above, has three similar doorways, one of which is blocked, along with two windows featuring four-centred heads and two lights each, separated by stone mullions and with dripstones above. The east wall of the south wing contains two stone lancets on the ground floor, and above them are two three-light windows, now blocked, with cusping of cinquefoil-headed lights and wooden mullions. The west wall features a similar window with six lights, positioned higher in the wall.
