Possible Locations

We are thinking of shooting the scene of the woman walking down the steps (shot 11) in London. We want a house that has steps leading up to the front door as we can shoot up at her and get the door an her into the shot at the same time. We need a location that will not mind us shooting on it so a house may be un practicle. There are a lot of hotels with the backdrop we need so we will enquire into using one of them .
