Proposals for the Manchester children's hospital parent's accommodation are expected to be submitted for planning consent in the next few months, say AEW.
The Manchester-based architecture practice, which is behind the Museum of Liverpool and Dawoodi Bohra Muslim Community mosque in Levenshulme, South Manchester, gained planning consent last year for a similar scheme in Birmingham.
The work being carried out is on behalf of the charity Ronald McDonald House.
The 60-bedroom building is located adjacent to the Manchester Royal Infirmary near Hathersage Road.
Steve Burne, managing director at AEW, said: "Plans are being worked up and will be submitted for planning consent in the next few months."
