Close up first impressions, the first thing your residents and in many cases their relatives are aware of is your main entrance signs. Over the door or adjacent to the entrance I would place a clear good quality sign displaying the home name and possibly the brand if part of a group. This can be in the form of a composite tray sign, a set of cut out individual Perspex letters or if the budget will allow a nice set of 3D stainless steel letters.

Two sets of glass doors are commonly used at the entrance to a modern care home with the lobby between the providing a barrier against the elements. The glass doors require a manifestation under health and safety regulations but why not instead of the standard 50mm dots brand them with a welcome message and your home name and logo.(it still on forms with health and safety regulations.)
