WELCOME TO [SI-MODULAR] - REINVENTING CONSTRUCTION

Thank you for your interest in our company. You may have seen some videos showcasing our system, which is great! First and foremost, SI is not yet a turnkey solution. Our system is primarily designed for self-build projects. If you're ready to dive into the details, please refer to our brochure, the price list and the boundary conditions. We apologize for any repeated information, but crucial details sometimes need to be emphasized. Building your own home is incredibly rewarding, but it's also serious business.


Building on this foundation, an intense design and development process began to create a modular building kit that met the brief without compromising the stability and durability of the final product. After presenting the innovative results, our [SI-MODULAR]® building kits quickly garnered worldwide interest, generating great enthusiasm and positive feedback.

Soon, we began receiving inquiries from the private sector, which motivated us to further develop our basic concept and offer a range of designs to meet diverse market needs. Today, we provide a sophisticated construction system that delivers high-quality, stable building projects globally, and meets the high building standards of the german housing market. Our solution for stress-free and practical construction has become the ideal choice for many projects in the private, local, and commercial sectors. Our goal is to make building easier.

We welcome your inquiry.

Sincerely,

Hans-Ludwig Stell

STELL INNOVATION GmbH

Our journey began in the spring of 2011 when the Kastell Foundation of Stadtlohn, Germany, commissioned me to design and develop a modular building kit. The goal was to provide safe, affordable, and sustainable housing that could be easily constructed in emerging and developing countries worldwide.

The brief specified that the kit should:

  • Offer components that are highly adaptable.

  • Be produced using industrial manufacturing techniques at an affordable price.

  • Be easily assembled with a minimal number of tools, allowing even the most inexperienced individuals to construct it in a matter of hours.

  • Be made of lightweight, sustainable materials that could be packaged and shipped at a low cost.
