Description
No. 12 Union Passage is a shop with accommodation above, built around 1806 and altered in the late 19th century with 20th-century additions. The building was likely overseen by City Architect John Palmer, but it features earlier elevations from around 1791 by Thomas Baldwin. It is constructed from limestone ashlar, and the roof is not visible from the street. The building has a single depth plan and is back-to-back with No. 13 Union Street, which has been redeveloped.
The exterior consists of three storeys with an attic, featuring a first-floor sill band and a parapet. The upper floors have two glazing bar sash windows with shallow reveals and six-over-six sashes. The ground floor has been altered with a mid-20th-century shopfront. The interior has not been inspected.
Historically, this building was part of a scheme to improve the city center following the Bath Improvement Act of 1789. Union Passage is a street that has existed since the Saxon period; it was previously known as Cox Lane and is shown on Smith's Map of 1588. This property has been altered over time but is included for its group value and stands on the site of the Friends' Meeting House, which was demolished in 1805.
