19, Union Passage

No. 19 Union Passage is a shop with accommodation above, built around 1806 with a mid-19th century addition. 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 has a Welsh slate roof.

The building occupies a corner site and has an L-shaped plan, with elevations facing both Union Passage and Northumberland Place. It stands three storeys tall with an attic and has a splayed corner. There are two windows on the Union Passage side, featuring six-over-six glazing-bar sashes in plain reveals. The mid-19th century shopfront has a pilastered doorway, and there is a narrow, chamfered revealed window on the first floor at the splayed corner, which has four-over-four sashes.

On the Northumberland Place side, there are three windows, coupled at the corner, with chamfered reveals and six-over-six sashes; the left-hand second-floor window of the pair is blind. The building has a moulded cornice and parapet, with a mansard roof that includes two flat-topped dormers facing Northumberland Place and one facing Union Passage.

The interior has not been inspected. Historically, Union Passage was part of an improvement scheme for the city center following the Bath Improvement Act of 1789. The street has origins dating back to the Saxon period and was previously known as Cox Lane, as shown on Smith's map of 1588. Northumberland Place was constructed on the site of a medieval close called Marchant's Court, which is depicted on Gilmore's Map of 1694.
