ST-4

For those who want to live together, but with their own space

ST-4

ST-4 is a unique model in the ST family – based on the ST-3 concept, but supplemented with a functional connector that allows for the convenient connection of two independent parts of the house. It’s an ideal solution for people who want to live close to each other, but at the same time maintain privacy and autonomy for each zone.

Well-designed space

The ST-4 layout allows for the creation of two fully functional residential sections connected by a common connector. This makes the house perfectly suited as a solution for multi-generational families – for example, with parents or grandparents living “just next door,” without sacrificing independence. It is also a very attractive option for those who wish to combine residential function with running a business, a private practice, design office, or workshop.

The right part can be designed as a mirror image of the ground floor of the left part, which allows for the creation of two similar functional layouts or adapting one of the zones for a completely different function – e.g., an office area, a guest apartment, or a rental space. ST-4 is a modern, year-round modular home that offers unprecedented flexibility in organizing family and professional life in one place.

Your comfort, our technology

ST-4 is a modular home with a connector, allowing you to create two independent living zones within one building. Ideal for multi-generational families or those who wish to combine their home with a company headquarters or office.

Work schedule

clear and predictable

Traditional house construction often drags on indefinitely. In the case of the ST-1 modular home, the process is transparent and fast, not exceeding 2 months:

In total, from the start of work to the completion of the ready house, 3 months* pass, or even less – this is a period during which, in traditional construction, we usually only have the shell state.
* The completion time may be extended in case of using unusual finishing materials or window joinery.
