The £25million project will increase the capacity of the Winter Gardens and enable it to host over 7,000 delegates.
Plans include new conference space for up to 1,200 delegates with additional ground floor exhibition space to accommodate around 380 people.
The new centre would be built on the site of the former car park on Leopold Grove in Blackpool.
A planning application was submitted 1 December. If funding is secured construction could start in winter 2017.
