17, SIR ISAAC'S WALK (See details for further address information)

No. 17 Sir Isaac's Walk is a large house built in the late 17th century, featuring a medieval cellar and an 18th-century front. It is also known as Headgate House or Rebow's House, named after the Rebow family, who were among the wealthiest and most significant in the town during the 17th and 18th centuries. Sir Isaac Rebow is reputed to have entertained William III in this house.

The building has two storeys and attics, with two hipped dormers at the rear. It is timber-framed and plastered, with tiled roofs and a half H-shaped plan that includes wings extending east at the back. These wings feature a coved eaves cornice made of plaster and roofs that are hipped at the east end. The front façade is plastered and has a parapet, with a five-window range that includes a central oriel window on the first floor. The windows are double-hung sashes with glazing bars, and the oriel is topped with a modillioned cornice. The ground floor accommodates shops and offices. Inside, there are some late 17th-century features.

Nos. 44 to 62 (even) are part of a group with No. 17 Sir Isaac's Walk.
