If they can finance it
They have recently secured £450 million for the build but need more.
Just don't understand why they are keeping it all under wraps. It would seem
to me that it just lets the 'conspiracy theorists / they're trying to hide the
truth from us paranoids' have a field day.
They already have several other large construction projects on the go, so, they are staggering the announcements and build times, otherwise the building works could be a little overwhelming.
