High Osgodby Grange

High Osgodby Grange is a farmhouse with an outbuilding, dating from the early to mid-18th century and altered in the 19th and 20th centuries. It is constructed of coursed squared stone with a Welsh slate roof. The main two-storey, five-bay section has a projecting design to the outer bays on its garden front. A parallel two-storey range extends to the rear, with a single-storey wing attached to the rear of that. A rear outshut is situated on the right-hand side. The garden front features 20th-century two or three-light transomed casement windows with projecting sills and keyed lintels. A central six-panel door, with the top four panels glazed and a three-pane overlight, is flanked by windows on each floor; the right bay is blind. A narrow window is located in the left bay, matching the earlier windows. The roof slopes down in a tower over the projecting outer bays and is finished with an ashlar coping. The roof structure includes an early red brick ridge stack between the two left bays and a smaller cross-ridge stack across the right bays. The rear elevation features an outshut with a slatted opening to the left and a wide, flat-arched window to the right. The two-storey range to the right has a later entrance door to the left, a blocked former doorway with a keyed lintel to the right, and a similarly lintelled window above to the left. The wing has a chamfered eaves band, cyma-moulded kneelers and ashlar coping. On the left return, there is an attic window with a keyed lintel. The rear range is pierced by a 12-pane sash window on the first floor. The right return displays a flat-arched stable door with a small window to the left, an inserted garage door with a timber lintel and a board door with an overlight under a flat arch in the gable.

The interior includes panelled doors, with a particularly fine double door on the first-floor landing. A panelled cupboard is located under the stair. A room to the left of the main entrance features an inglenook with a chamfered, cambered bressummer supported on a corbel from the left wall and a heck post on the right; a large scantling spine-beam and a cyma-moulded cornice are also present. A dog-leg, open-string stair has a moulded handrail and two turned balusters per tread, except for the lowest flight. A spiral stair leads to the left end of the front attic, which is separated from the rest of the attic. This area has a collared principal rafter roof truss and square section rafters and ridge-piece; the remainder of the front attic has similar trusses with angle braces to collars and tusk-tenoned purlins. The rear attic reveals one truss visible, having a king post with a collar forming a cross and V struts.
