Description

Wych Elms is a house built in 1912 by Sir Edwin Lutyens. It is constructed of red brick and features a steeply pitched plain tile roof. The building has one storey and attics, with a long range and two deep panelled ridge chimney stacks. The entrance is located on the right side of the centre in a two-storey gabled bay. It has a glazed door with a simple moulded hood, and the gable is adorned with a twin casement window, flanked by hipped casement dormers. There is tile creasing present. On either side of the door, there are large four-light casements. The left end of the house features corner windows with four large lights, and the ground floor is open in the centre. The gable is tile-hung.

Local climate

Wych Elms sits in a drier-than-average part of the UK, with an average of 720 mm of rain a year. This makes it drier than 84% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 77% of listed buildings.

It experiences an average of 36 freeze-thaw cycles a year, more than 61% 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.
