"I'm Lottie the lift girl. Let me take you to where you want to go.

If you don't know the name or address of the building you need to visit, key in the name of who you want, or the name of the business.

Or maybe you're just looking for a type of business, such as architect or physiotherapist or estate agent - so just key in the type of business and any that are in tower blocks will show up for you to choose from."
