[K-Trend] The Rise of 1.5-Person Households: Paradigm Shift in Korean Housing and Co-living Solutions

Conceptual Definition: A new form of housing in Korea that combines the independent privacy of a single-person household with the social solidarity of a multi-person household, reducing housing costs while alleviating isolation.
Background of Spread: To resolve rapid increases in housing costs in major cities like Seoul and the psychological isolation of single individuals, housing models sharing communal living rooms and kitchens are rapidly expanding.
Social Value: Beyond mere space sharing, it is becoming an alternative to improve quality of life by integrating data-driven wellness management and smart home technologies.

Subscription-based Housing Services: It takes the form of ‘Housing as a Service (HaaS),’ maximizing time efficiency by outsourcing domestic labor like cleaning, laundry, and breakfast services.

Define Location and Budget: Research market prices for co-living houses near major business districts and universities in Seoul, such as Gangnam, Mapo, and Seongsu.
Verify Operator Expertise: Choose professional companies that specialized in community management and security systems, rather than simple real estate rentals.
Review Shared Facility Rules: Thoroughly check detailed operating regulations, including kitchen usage hours, visitor policies, and appliance management.
Utilize Short-term Stay Programs: Before signing a long-term contract, experience a short stay of one week to one month to see if it suits your personality.
Link with Digital Nomad Visa: For foreigners, use the “K-Digital Nomad Visa” to register a professional co-living house in Korea as a long-term residence.

Q1: Is 1.5-person housing more expensive than regular rent?

Q3: Can the 50-60 age group reside in a 1.5-person household?
- A3: Yes. More seniors are choosing senior-specialized 1.5-person housing models to prevent social isolation and receive professional health management after retirement.
