Not much use going to Brighton & Hove City Council for planning permission. Falmer comes under the jurisdiction of Lewes.
Well there we go then, you've just proved my point that extending the stadium to an ambitious level will probably fall on deaf ears given how many people were against a stadium for BHAFC that's not even in the city itself.
Personally, I think it'd be morally wrong to allow a hefty extension in the short term as the infrastructure and original planning application does not provide for this.
