As far as the new hangar at Goodwood is concerned, planning permission was given some months ago (a matter of public record) and construction has started alongside hangar 2, the oldest hangar (which is plain to see if you visit the aerodrome). According to the recent aerodrome information sheet completion is planned for early July.
As far as "Goodwood itself" is concerned, what would you like to know, and (as this is your first post on PPRuNe) for what reason?
Sorry if that sounds unfriendly but as with most airfields there are local antis, and I have no wish to supply ammunition.
My aeroplane has been based there since 2001 and I have been flying from there on and off for >25 years.
