Description

Gosmore House is a house that originated with its northern wing in the early 16th century, while the main range was built in the mid-17th century, and the southern end dates from the 19th or 20th century. The structure features a timber frame that has largely been cased or replaced by brick, with a stuccoed exterior and steep old red tile roofs. This large, two-storey house is asymmetrical and set back in its grounds, facing west.

The northern section includes a two-storey crosswing that was built next to the site of a former small open hall, which has since been replaced by an internal-chimney, lobby-entry plan. This layout consists of a hall to the north of the stack, a parlour to the south, and a staircase likely located at the rear of the stack. The west front showcases a gabled crosswing on the left-hand side and features three small gables above the main upper floor windows, each adorned with bargeboards and pendants. There are label mouldings over the main windows and an arch over the upper window in the left-hand gable. The windows are small-paned casements, typically arranged in three lights.

A projecting flat-roofed central porch leads to a half-glazed door, which is topped with a flat moulded hood supported by shaped brackets. The northern end of the house includes a semi-octagonal bay window that rises two storeys and is decorated with a moulded cornice. Inside, there is a large internal central chimney with three conjoined diagonal shafts. The interior features wallplates in the 16th-century crosswing that are lower than the tie-beams of the hall range. The hall range also has chamfered and hollow stopped axial beams, and the original timber lintel above the fireplace has been raised. There is a partition on the first floor over a crossbeam in the large room to the south of the chimney. The roof is constructed with clasped purlins and long straight wind-braces.
