The former Imperial Tobacco headquarters in Bristol is being turned into apartments.
The Hartcliffe apartments go on sale shortly
About 400 flats at the listed building in Hartcliffe, now known as Lake Shore, are soon to go on the market from about £100,000.
Developers Urban Splash said the project would be "kind to the environment", with plans for residents to use electric cars.
A spokesman said: "These are exciting times for south Bristol."
Urban Splash started development work in Manchester and Liverpool.
It bought the former Imperial Tobacco HQ four years ago as part of a £45m deal.
Jason Collard, from Urban Splash, said: "We're not a mainstream developer but what we create is unique."
The Bristol project is expected to be completed in two years.
