Designs to convert the Sauchiehall Street building into a 112-bed hotel have been drawn up by Mosaic Architecture + Design.
The delivery of a Qtel will save the building bringing a £12m investment to the historic part of the city centre.
The proposals include a rooftop extension to provide bedroom accommodation, while the ground floor will house the hotel reception and a restaurant.
Mark Bailey, Director of Manor Property Group, said: “The plans for our first Qtel branded hotel, on Glasgow’s Sauchiehall Street, will see this Art Deco building given a new lease of life.
“We have identified hotels as a key area for development and intend to expand our existing nine hotel portfolio by developing six more hotels of 100+ guestrooms, with the possibility of further expansion once this milepost has been reached.”
