A glass conference centre is to be built on the roof of the historic Fort Dunlop building, visible from the M6 near Birmingham.
Property investment firm European Property Investors Special Opportunities 3 bought the landmark building from architect Urban Splash last year.
The 35,000sqm Grade A listed building is home to the Birmingham Post and Mail and a Travelodge Hotel.
Now the new owner wants to add a conference centre on the roof to make the most of the views of Spaghetti Junction and the city.
EDG property director Neil Edginton is leading the project for the new owner and said several million pounds would be invested if the plans get the backing of Birmingham City Council.
He said: “Urban Splash did an amazing job, and a lot of the offices have been let, now this is the next chapter for Fort Dunlop.
“The point is that there is this amazing roof space out there with some clear views across the city, but at the moment the chance of using that space is limited due to the weather.
“So we took a view we wanted to make the most of that space by creating something made from glass so you can still enjoy the views.
“There is demand for conference and meeting space, so this will be something new we can offer people.”
If the plans are passed, there will also be a second level added to the car park and a dedicated car park in front of the Travelodge hotel.
