Grimston Garth

Grimston Garth is a house built between 1781 and 1786, with service ranges added around 1815. Further additions from around 1860 were mostly removed during restoration in the 1980s. It was designed by John Carr for Thomas Grimston. The house is constructed of red brick, which was formerly colour-washed, and features rubbed brick dressings and a slate roof, showcasing a Castle Gothick style.

The building has a triangular plan with a central hexagon and round corner towers. Two parallel service ranges, each ending in a circular tower, extend northward from the original rear service range. The entrance elevation is two storeys high with four bays arranged as 1:2:1, flanked by three-storey turrets. It features six-panel doors adorned with trefoils and quatrefoils under pointed brick arches with hood-moulds on either side. The pointed sash windows have intersecting glazing bars and are also topped with hood-moulds. There is a first-floor band, and the sashes on the first floor also have glazing bars under hood-moulds. The building has a parapet band and a crenellated parapet. The turrets exhibit similar fenestration and bands, with the second floor featuring triple lancets under hood-moulds and crenellated parapets.

The central hexagon on the second floor has six-pane sashes with sills and hood-moulds beneath a parapet band, a crenellated parapet, and a pyramidal roof. The garden elevation and service wings display similar architectural features. Inside, the ground floor hexagonal dining room boasts a pilastered fire surround with blind ogee tracery above the fireplace, and a frieze of pointed arches interspersed with heraldic shields beneath an ornate cornice. The south-east turret contains a cut-string geometrical staircase with balusters shaped like clustered columns and a slender, moulded, wreathed handrail. The north turret in the eastern service range features a tester bed that folds into a cupboard. The house is set within parkland that includes an icehouse, a ha ha, a walled kitchen garden, and a separately listed gatehouse and stable block.
