Crews remain on scene along with police and water engineers.
Images taken at the scene show the building was completely destroyed and just a shell remains.
An investigation has been launched to find out how the fire started.
Nottinghamshire Fire and Rescue Service say they hope to resolve the Forest Road fire as soon as possible and would like to thank the local community for their support and to ask the public to avoid the area due to smoke.
Residents living in Bessemer Drive are now able to return to their homes on foot.
Those living on Bessemer Drive will only be able to access their homes via the back pedestrian entrance through Clifford Street.
This is due to debris being in the road and a building collapse at the scene. Residents are advised they will not be able to get into their vehicles and drive on Bessemer Drive due to these circumstances.
Those returning to their properties are asked to please keep all doors and windows closed. Residents are also advised to not go into their gardens due to smoke and debris and concern about potentially hazardous materials.
Inspector Katie Eustace, of Nottinghamshire Police, said: “I want to thank everyone affected by this fire for their patience as we understand how scary and upsetting an incident like this can be for everyone involved, so I want to say thank you to everyone who has worked with us and stayed away throughout yesterday and today.
“Thank you for your support and understanding.
“Our colleagues at Nottinghamshire Fire and Rescue Service remain on scene.
“Officers will continue to be in the area so please do speak to them if you have any queries as you return to your homes.”
The incident remains under investigation.
Forest Road will remain shut at the junction of Sandhurst avenue and Nottingham Road while the investigation continues.
Oak Tree Leisure Centre, in Jubilee Way South, will close shortly as those affected are allowed back into their homes.
Anyone with any information is asked to call 101, quoting incident number 523 of 18 March 2023
