Description

Red Stack is a house from the late 17th century, featuring a timber frame on a stuccoed base and roughcast walls, topped with steep old red tile roofs. The building is 1½ storeys high and consists of three cells, following a lobby entry plan that faces east. It includes a 19th or 20th-century northern bay and a gabled rear wing at the northwest. The front has four windows, with three tall gabled dormer windows at the eaves, featuring 3-light flush casement windows with small panes and a central plank door. The dormers have 2-light casement windows. A tall rectangular central chimney has an ovolo capping on its rectangular lower stage, which is topped by six conjoined diagonal shafts. At the rear, there are two similar dormers and a small window under the eaves to light the stair beside the chimney.

Inside, there are two heated rooms with back-to-back fireplaces. The southern room serves as the hall, while the southern end originally contained two small rooms. The rear wall displays surprisingly late Kentish framing with slightly curved tension braces. The roof features collar trusses without tie-beams between the gable ends, with trusses in the partitions flanking the stack and at room divisions below. The upper chambers were not originally heated. Notable features include a face-halved bladed scarf in the wallplate by the stair, chamfered axial floor beams, and open fireplace lintels. Red Stack is of special interest due to its plan and construction.

Local climate

Red Stack sits in one of the driest parts of the UK, with an average of 700 mm of rain a year. This makes it drier than 92% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 78% of listed buildings.

It experiences an average of 35 freeze-thaw cycles a year, more than 59% of listed buildings. Of these, 17 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
