The Mail Online has a report and photos of further filming at Skyfall Lodge, built at Hankley Common in Surrey. The report contains a number of spoilers, so if you don’t want to have your enjoyment of the film spoilt by learning what happens then hit the back button now. The report says:
Flames soaring hundreds of feet in the air were seen right across Surrey as the purpose-built mansion was set on fire. It made for an impressive sight as the plywood and plaster stone building was engulfed in flames. Surprisingly, considering how quickly the flames spread, the scene was actually shot over a couple of nights.
