A couple from Copenhagen invented the 21-5 co-ownership model in 2008. Since then, more than 1,300 families have joined a 21-5 Owners‘ Association, making 21-5 one of the world’s leading concepts for sharing private holiday homes. 21-5 is a unique concept where 21 families co-own and share five holiday homes in attractive destinations. The company manages the entire process, from purchasing and renovating the homes to ongoing maintenance, allowing families to enjoy their holidays without the hassle of property management. The concept is designed for families who value quality time in well-maintained, beautiful surroundings.
