‘Mini Storage Attic’, the industry's first event to break 200 stores… Discount of 50 million won upon starting a business
[Ttangjipgo] Korea's No. 1 shared storage brand ‘Mini Storage Attic’ operated by Second Syndrome Co., Ltd. is holding a business support promotion to celebrate the industry's first event to break 200 stores.
This promotion includes a discount benefit of up to 50 million won on investment for new business owners opening new locations of ‘Mini Storage Attic’ during the remaining period of this year, along with an additional open marketing package valued at 1 million won. The marketing package is designed to support tailored promotion through online and offline channels to help new locations establish themselves quickly.

Recently, there has been an analysis in the industry that the increase in vacancies due to the real estate market downturn has led to the use of commercial and underground spaces as unmanned shared storage, emerging as a new form of investment. As the number of single-person households with limited living space increases and the population enjoying hobbies like camping grows, cases of subscribing to 'my own storage' to reduce belongings are increasing, leading to the growth of the shared storage market.
The advantage of unmanned shared storage is that it can be opened in commercial areas with low foot traffic. As long as there are facilities like parking lots and elevators for moving items, it can be operated, making it a trend considered a profitable model to activate vacancies from the building owner's perspective.
In fact, in overseas markets such as the United States and Japan, self-storage, which means shared storage, has established itself as a separate real estate investment sector and living infrastructure for over 30 years. In Korea, the National Pension Service included self-storage in the new real estate investment sector last year.
In this context, the domestic shared storage brand ‘Mini Storage Attic’ started with its first store in 2016 and has now surpassed 200 stores. It is the only brand in the country with no closing cases. It has been evaluated that the incorporation of AI technology into storage, called ‘Space Intelligence’, has maximized the efficiency and profitability of idle space operations. Additionally, through an unmanned automation operating system based on AIoT and Edge Computing, 24-hour management is possible, and the system includes ▲ real-time temperature and humidity control ▲ access control ▲ insurance services.
A representative from Second Syndrome Co., Ltd. stated, “Mini Storage Attic maintains a unique market-leading position in terms of operating area and automation technology with no competitors in Korea,” adding, “We hope that through this promotion celebrating the breakthrough of 200 stores, more building owners and prospective entrepreneurs will experience a stable business model in the rapidly changing real estate market.”
Meanwhile, inquiries related to starting a business with ‘Mini Storage Attic’ can be made through the ‘Start a Business’ section on the official website.
