Drumoak-based developer, McDonald Properties, wants to build on the old filling station on the A90 Aberdeen to Stonehaven road at Hillside, Portlethen.
Planning permission in principle is being sought from Aberdeenshire Council for a two-storey garden centre complete with a restaurant and 96-car car park on the brownfield site in green belt land.
The petrol station closed in 2007.
Agents for the developer, Lippe Architects and Planners, said: "Clearly there has been no interest in the site being taken forward as a petrol filling station.
"The proposed curved green roof will create an aesthetically pleasing profile that will blend into the existing visual landscape providing the existing residential properties on the other side of the A90 with a natural, green and pleasant outlook.
"There is an appreciation that the site should not stay in its current derelict state for much longer. It has deteriorated in condition over the years and is a magnet for vandalism.
"This is not a positive image for the outskirts of Portlethen being so visible from the main road."
