Description

Isacson's is a house dating from the early to mid 14th century, originally serving as a range of lodgings, possibly for the Knights Hospitallers. The building is constructed of limewashed clunch with plain tile roofs and features local 18th century brick chimney stacks. It stands two storeys high with attics and a basement, and was originally divided into five bays by buttresses. The layout consists of three rooms, including a central hall with a cross-passage that has a recently unblocked two-centred arched doorway.

On the north-east elevation, there are two ogee-headed doorways at the first floor above two two-centred arched doorways at the ground floor, which previously provided access to a now-demolished porch and stair turret. An 18th century staircase is located in the rear double garderobe, which was extended to form a wing during the 18th century. The south-west elevation features a chamfered eaves cornice, a plastered plinth, and parapet gables, with a nearly complete garderobe to the north-west and an original external stack. There is a ridge stack to the right of centre and an end stack at the south-east.

The windows on both floor levels, originally consisting of four trefoiled lights with chamfered mullions and flat-headed arches, have been either blocked or replaced. The first floor now has six flush-framed hung sash windows, while the ground floor has five larger ones. A 19th century four-panelled door is located on the left side, and a doorway on the right side has been blocked. Inside, the room to the north-west retains 18th century panelling and a chimney piece, along with one embattled cornice that has been relocated to the passage beside the central stack. Other carved timbers from the 14th century are believed to have originated from Ely Cathedral. The roof features contemporary collar rafters.
