Description

Mymsmead is a house located on Blanche Lane in South Mimms, likely built in the early 17th century. By 1787, it was converted into two cottages, and by 1842, it had been divided into four cottages. The building features a brick ground floor and roughcast above, which is likely timber-framed, topped with a tiled roof.

Originally, it had a three-bay lobby entry that was extended by one bay to the left. The house is two storeys tall, with a central entrance in a slightly projecting bay that has a plank door set in a timber case with a four-centred head and a bracketed, moulded hood. On either side of the entrance are two-light lattice casements, and there is a three-light casement to the left. To the right, there is a rectangular ground floor bay.

The first floor is roughcast and features two-light casements, three of which are leaded, with one having timber glazing bars. A large axial ridge stack is positioned between the two right bays, while a smaller ridge stack is found between the two left bays. There is also an external end wall stack to the left. The right return of the building includes a large two-storey semi-octagonal bay addition with tile-hanging on the first floor. Additionally, there is a two-storey tile-hung extension with an open ground floor and a hipped roof at the rear right, along with a lean-to brick extension that has a side entrance at the rear left. The interior has not been inspected.

Local climate

Mymsmead 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 91% of listed buildings in the UK. Its exposure to wind-driven rain is lower than that of 90% of listed buildings.

It experiences an average of 33 freeze-thaw cycles a year, fewer than 54% of listed buildings. Of these, 15 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.
