#. Finally, Mr. Kim (64), a retired civil servant who had a romantic interest in separate houses, a separate house in the past five years. The house building work, which started smoothly five years ago, encountered obstacles such as financing problems and did not make any progress for about two years. As soon as he was about to go through the procedure again, he was caught again as the price of his dust increased this time. Mr. Kim shook his head, saying, “If I had known that building a single-family house would be so difficult, I wouldn’t have started.”

The core of Zeigeist is ‘prefab’. Abbreviation for prefabrication. In this construction method, building members are manufactured in a factory in advance and assembled on site to complete the house. A house is simply divided into a living room, a master bedroom, a small room, and a bathroom, and each space is pre-made in a factory. After that, the product is moved to the place where the house is to be built and assembled. It is similar to building ‘Lego bricks’.

CEO Ran Ok said, “The biggest advantage of the prefabricated method is that it can shorten the construction period compared to the traditional on-site construction method.” You can save 40% of your time,” he said.

“Recently, in a situation where the price of raw materials and labor costs are rising day by day, reducing time means reducing costs,” he said. It is also positive that it can reduce and produce uniform products.”

More than 50 module combinations, creating countless designs… A detached house is also ‘DIY’

The equivalent of ‘Lego’ is a module. More than 50 types of modules have been developed by Zeigeist. The types of houses that can be created by combining modules are almost endless.

Representative Okran explained, “The reason we created about 50 modules was to compensate for the current weakness of detached houses, such as a lack of design. .

“For example, an apartment cannot satisfy the taste or convenience of 1,000 indefinite people, so it is designed so that users can live conveniently according to the judgment of the company, but a detached house has no choice but to include taste and way of individual living,” he said. To achieve this, different types of modules can be used.”

From the windows that enter the house to the shape, form and size of the house, consumers can decide everything. “The size of the house can be increased by increasing the number of rooms in the form of adding modules to the existing design,” said Ok. We can even set the location, so the response from users is good,” he stressed.

There is a great demand for rebuilding and remodeling old houses into new ones, and it is easy to do with modular houses, he stressed. He said, “If you’ve lived in a modular house for decades and the house is old or worn out, it’s possible to rebuild or replace some of the modules,” he said.

However, he explained, “As soon as the module is separated, the installation pipes or electrical equipment are cut off, so they need to be connected again.”

Securing a significant share in the detached housing market… Moving on to steel modular buildings

Zeigeist’s short-term goal is to secure a significant share of the detached housing market. According to the company, an average of 45,000 single-family homes are started each year. Among them, there are 7,000 to 9,000 wooden houses. The annual supply of the separate housing market leader is around 300 households, and the share is less than 1%.

“First of all, our short-term goal is to secure a 3% market share in the wooden single housing market,” said CEO Okran, “The main goal is to revive the modular construction market.”

Furthermore, Zeigeist plans to supply steel frame (steel) modular buildings for mid-rise and high-rise buildings. CEO Ok said, “As we gain experience with wood modular homes, we will also expand into the mid and high steel modular market.”

He emphasized, “At the moment, we are starting with wood, but in the end, building a modular building with various materials will be the final picture.”
