The two-storey ashlar building is in Greek Revival style.
The original design is similar to Francis Goodwin's previous design for the (now-demolished) Manchester Old Town Hall, and is modelled on the Erechtheion in Athens.
The Churchside façade of 1823–24, which Clare Hartwell and co-authors describe as "a little constricted", has a large central portico with four plain (unfluted) Ionic columns topped with a pediment.
The portico is flanked by single bays, with sash windows divided into three parts on the first floor.
On the ground floor is a simple sash window to the left-hand side and a double doorway to the right.

A wider west front on Chestergate in the same style was added in 1869–71 by James Stevens, a local architect from the town.
It has nine bays, with a central portico that matches the Churchside one.
The doorway, now the building's main entrance, is topped with an architrave of polished granite.
Flanking the portico are three bays delineated by pilasters.
The inner two bays have sash windows to both ground and first floors that are divided into three parts by pilasters.
Stevens' design also included a steeple that was not built.

The building incorporates the former Borough Police Station at what now forms the rear.
Added by Stevens, it adjoins Goodwin's Churchside façade.
The entrance is flanked by paired sash windows.
Over the ground floor is carved "BOROUGH POLICE STATION".

The extension of 1991–92, by Conder UK and HLM Architects, is a Georgian-style, two-storey office building, in red brick with faux stone dressings.

The courtyard contains stones from the porch of Macclesfield Castle, dating from around 1398.
