The City of Lincoln Council has received a planning application to convert a former restaurant building into residential accommodation and shops.
Slipper Baths, next to the Witch and Wardrobe pub on Waterside North, has currently space for two restaurants.
In the past, the building housed Italian restaurant Prezzo and Wok N Grill, and later Japanese style restaurant Kashi.
The now-disused building has been nominated for a RIBA East Midlands design award in the past due to its intriguing shape.
Now, plans by Warrant Developments Ltd aim to convert the first floor into four residential units, each with its own access, plus four retail units on the bottom floor.
According to the planning document, the external appearance will be mainly unchanged.
Due to the building being sat slightly back from the street, signage columns are also proposed for the front of the building.
The signage will look similar to those that will shortly be in use by the Waterside Shopping Centre nearby.
The site carries the name of Slipper Baths after its former use from 1931 to 1999 as public conveniences.
Prior to the baths, a public house was there between 1857 and 1863, then a lodging house from 1899 to 1913, then a grocer during the 1920s. The building was demolished to make way for the baths building.
The Slipper Baths were demolished in 2001 and the current structure was built in 2006.
