Developers want permission to knock down Swift House, Kingfisher House and Sackville House in Northwood Park off Gatwick Road.
Replacement state of the art offices were granted planning permission back in 2017.
Now a prior approval application has been lodged with Crawley Borough Council to demolish the three office blocks.
