Pupils from the local Holland Road Junior School selected a number of names for the care home, with residents at the nearby Tandridge Heights care home voting for the favourites.
The final choice was thought up by pupil Will Evans, reports Edenbridge County Border News.
He will receive £50 worth of cinema vouchers and £100 book vouchers for the school.
The vote was held shortly after the general election, so that residents at the care home could follow up their national ballot with one that is closer to home, and potentially closer to their hearts.
Windmill Manor, which will be a 60-bed purpose-built campus, is expected to open this autumn and will provide general nursing and residential care as well as personalised dementia care.
The new site will also feature a Memory Lane Community specially designed for those with dementia to include colour schemes that engage residents and help them identify areas within the home.
