I've just had an email about the proposed gym and I think it's a great idea! The area is still crying out for a hub, a sort of "village centre", and having a gym in the road would attract people who, as the email suggested, might then shop at/use other amenities in the street. As for music noise, the music - if they have it - wouldn't have to be THAT loud would it? And presumably the gym would have to close at a reasonable time anyway, not much beyond nine in the evening?
