A container house is a portable, reusable building product. Also known as "modular container houses" or "container-style houses." Designed and manufactured in a modular fashion, these units can be used individually or combined horizontally and vertically to create spacious living spaces, stackable in the vertical direction. The container units are standard components, welded from special steel, connected by bolts for a simple and quick installation. They are suitable for real estate development company sales galleries, product sales displays, temporary reception centers, commercial temporary offices, shops, and more.
