Developers behind ambitious plans to build more than 300 apartments near the city's train station say they are likely to be ready in two years' time - for when 4,000 workers will move into a complex nearby.
Planned in Arkwright Street, the developers want to create 331 apartments, which they say will target professionals.
The 2021 completion date is planned to coincide with the opening of a huge new building called Unity Square, near Nottingham Railway Station, where HM Revenue and Customs staff will relocate from their Castle Meadow site.
Alex Newbold, project manager at the Cassidy Group, said: "The site already has consent for a mixture of 420 student beds and 149 rental apartments, which Cassidy Group is currently in the process of applying for planning permission to amend to an entirely build to rent (BTR) scheme of 331 apartments, including three retail units and 96 secure parking spaces.
"The Arkwright Street site is ideally located for 100 percent BTR scheme as the site is within 100m of the forthcoming new regional headquarters for HMRC and within 135m of the main train and tram station.
"The new HMRC offices will have 4,000 employees and is due for completion 2021.
"The majority of the workforce will be from outside of Nottinghamas they are closing other offices and centralising them.
"As a result there will be a very large number of these employees that will require housing.
"The proposed 331 BTR scheme would be completed in 2021 to coincide with the opening of the new HMRC headquarters."
The developers are working on creating a planning application for the revised scheme.
It forms one of a number of Cassidy Group property developments across Nottinghamshire.
One includes a bid to create 15 new apartments at the site of a derelict Victorian warehouse on London Road, in the city centre, which will be called Chainey Place.
Another project includes a huge 350-apartment scheme behind the Hicking Building, called Saffron Court.
And the Cassidy Group is also working to create a huge accommodation block for more than 400 students next to the Intu Victoria Centre, called York Place
