Northgate House (Formerly Judge's Lodging Now the Municipal Offices)

Northgate House, formerly known as the Judge's Lodging and now the Municipal Offices, is a mid-Georgian building that stands three storeys tall. It is constructed of brick on a stone plinth, featuring stone strings at the first and second floor levels, as well as at the first-floor cill level. The building has a moulded stone cornice and a brick parapet with moulded stone coping, topped by a hipped slate roof.

The main block has five windows on the upper floors and four on the ground floor, all adorned with moulded stone architraves and retaining their glazing bars. The central entrance features a six-panel door with an arched radiating and wreathed fanlight, sheltered by a stone Ionic porch supported by two columns, with wall pilasters and an entablature that includes a curved frieze, bracketed cornice, and pediment. This entrance is approached by three stone steps leading to a stone landing.

To the right of the main block, there is an additional section with a half-octagon bay facing the road, which follows the same general design and includes three windows on each floor. The garden front mirrors the street elevation. To the left, there are double curved stable walls made of red brick on a stone plinth, featuring stone coping and square stone piers with moulded caps and bases.

Although the interior has been altered for its use as Municipal Offices, it still retains some notable late 18th-century fireplaces. Northgate House, along with St Mary's Congregational Church and Nos 19 and 20 Sandcliffe, forms a cohesive group.
