Description

New Court Number 41 is a detached cottage, likely originally built as accommodation for the caretaker of the New Court complex. It was probably constructed around 1854 for the philanthropic solicitor Hugh Jackson. The cottage is built of yellow stock brick, with a slated hipped roof. It is a single-story structure with a basement. The front features two windows, one of which is blind, and a narrow, single-height extension to the right. A segmental arched doorway, now fitted with a 20th-century door and overlight, is approached by steps. Segmental arches frame the sash windows. The interior has not been inspected. The cottage forms an integral part of the wider New Court complex.

It experiences an average of 30 freeze-thaw cycles a year, fewer than 66% of listed buildings. Of these, 13 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.
