ST ERTH TREWINNARD LANE SW 53 SW 6/258 Trewinnard Manor Farmhouse, - including garden walls and gate piers adjoining to north II*

Manor house, including garden walls and gate piers adjoining to north. Circa early C18, possibly incorporating remains of older house. Granite rubble with granite dressings. Steep hipped grouted scantle slate roofs with brick chimneys over the cross walls between the reception rooms and over the right-hand end. Some cast-iron ogee gutters. Plan: L-shaped plan plus projection to rear reception room carried on squat piers stones. The main range is double depth and 3 rooms long with parlour, left; hall, middle; and kitchen on lower ground, right. Behind the parlour is a back parlour with projecting window bay; stair hall behind hall and back kitchen or dairy behind kitchen. Built forward on the left is a 2-storey-over-basement cross wing containing a large parlour and another stair hall behind. Exterior: 2-storeys plus attic lit by 2 hipped dormers at rear. 2:2:2: bay south east front plus end of cross wing built forward on the left. Flat arches over openings. There is a room behind each pair of bays. Central entrance bays have principal doorway under the right-hand window. Right-hand bays fronting the kitchen, have windows at a lower level. The return wall of the wing forms another bay with ground floor entrance. Original doors, doorcases and windows. Main doorway has pair of glazed doors with arch-headed glazing and round panes in the 2 spandrels. Over the doorway is a shell hood carried on consoles. Other doorway has doorcase with panelled pilasters and pediment with later fire insurance plaque. Door has 9 panes above lock rail and a 6-pane overlight. The 18-pane windows to this front and most of the other windows to the house are original C18 hornless sashes with wide glazing bars with internal ovolo mouldings. Left-hand front has 12-pane sashes and 2 light chamfered granite mullions to the basement as plinth. (There is another similar mullioned window at the rear under the stair window). First floor windows are C18 6- pane casements. Rear has C18 2-panel door and original sashes except for horned replacement right of the doorway. Projecting window bay on the right is carried on squat piers (like a granary) and has a modillioned eaves cornice. C18 sash to the middle and another in the left-hand side wall. Set into the right-hand wall of the house on the first floor there is a remarkable oriel window with moulded granite base (presumably C17 but resited). The window itself is later replacement. Towards the rear from this window is a joint indicating that either the rear rooms were added at some time circa early C18 or that this end of the house is retained from the older house. Interior: Unaltered C18 interior in all parts of the house inspected. The C18 features include chimney-pieces, wooden panelling, ceiling cornices ; doors and doorcases in the 4 reception rooms and stair halls and 2 stairs with turned balusters. The main stair is an open well and has moulded closed string and bolection mouldings to the panelling under. The wall panelling in the hall and stair hall is raised and fielded. The kitchen is also unspoiled and largely unaltered since the C18. First floor rooms and roof structure not inspected but presumably also original (C18). Low C18 rubble walls adjoin north corner of house, with hog's-back granite coping and tall square on-plan granite monolithic gate piers with moulded caps. The walls are quadrant on plan beyond the gateway and linked to a taller terrace wall at right- angles which has small gateway with similar piers and granite steps down to the lower level from the front garden of the house. The low walls are surmounted by old wooden railings with turned finials. The pair of gates are ramped up at the sides to pairs of hanging stiles. Turned finials. In the C17 Trewinnard was the home of the Trewinnard family; in the C18, C19 and early C20, of the Hawkins family. The early C18 Trewinnard coach survives in Truro Museum. Trewinnard is one of the most complete houses of circa the early C18 in this part of Cornwall and retains a wealth of original features. The C18 sash windows that survive are particularly rare and important. Compare Tredrea q.v., and Gear and Kerrow Farmhouse, also in St Erth parish.
