If you were shooting interior shots of a building or from within the privately owned/rented grounds of said property, you would definately have to have what is known as a 'property release' signed, (same thing as a model release) but to shoot it as a part of a general background you do not have a problem. Filming for movies is a different matter as each local authority has quite a bit to gain in licences. Don't worry about stills though. Mike
