The Smallest House on The Quay, Conwy, will be be part of the World's Biggest Coffee Morning which takes place today.
The event, organised by Macmillan Cancer support will see people across the UK and further afield, hold a coffee morning, where donations on the day are made to Macmillan.
The house is one of more than 8,167 World's Biggest Coffee Mornings to be happening across Wales.
Rose Batten, who works at the house and is organising the event with four others, says: "It's our first one and five of us are organising it jointly and we'll have raffle as well as cake.
Everyone has been baking to be ready for the coffee morning and we're all really excited. We're hoping the weather will be good as it will be held outside the house."
