Investor

Is OktoGreen suitable for individual investors or mainly institutional investors?

OctoGreen is accessible to both. While institutional partners can participate in larger portfolios or regional scale-ups, individual investors are welcome to contribute from €75,000 as kick-off capital in specific projects. This hybrid model ensures that both private investors and professional partners can take part in the green building transition.

What are the financial benefits of investing with OktoGreen?

Investors benefit from a combination of fixed annual returns, success bonuses per home sold, and optional capital gains tied to project performance or asset appreciation. Because OctoGreen operates with optimized margins and direct sourcing, returns are competitive while risks are mitigated through structured, notarial-secured investment paths.

What types of projects does OktoGreen support?

OctoGreen focuses on residential housing projects with a strong emphasis on energy efficiency, smart technology integration, and regional scalability. These include detached and semi-detached homes, urban infill projects, and modular developments for rental or ownership. All projects are optimized for BEN compliance and executed using a standard material and technique pool.

How does OktoGreen ensure transparency and accountability in its investment projects?

Each OctoGreen project is structured with clear legal safeguards, including notarial oversight and transparent project documentation. Investments are always tied to specific developments, with capital only released after bank financing is secured. Investors receive regular updates, financial reporting, and — in some cases — direct notarial registration for maximum accountability.

What is the OctoGreen concept all about?

OktoGreen is a scalable building and investment model focused on sustainable, high-performance housing. It combines industrialized construction methods (like SIP panels and prefabricated components) with efficient project execution and direct material sourcing — resulting in faster build times, lower emissions, and optimized cost control. The goal: making nearly zero-energy homes (BEN) both affordable and investable.

Builder

How soon will I find the first contract?

Once you’re approved and available, you can be assigned to a project within 2 to 4 weeks, depending on region and planning. We work transparently — if there’s a suitable project ready, you’ll be invited directly to accept the assignment.

Is there any warranty required?

No. You’re not required to provide any personal or financial warranty. As long as the work is performed according to our building instructions, quality control and technical responsibility are handled centrally.

Can I work as a self-employed subcontractor?

Yes — in fact, that’s essential. All builders operate fully independently. You decide which projects to take on and when. OctoGreen provides clear technical documentation and planning, but you retain full autonomy as a subcontractor.

What kind of projects will I be working on?

You’ll work on modular, low-energy houses assembled using prefabricated SIP systems. Each house is built from start to finish on a single location over ±40 working days — with clean execution, minimal transport, and no multi-site hopping.

Can I take a break between projects?

Absolutely. You decide your own planning. Many teams choose to work project-by-project, then take 2–3 weeks off before accepting a new assignment. There’s no long-term obligation — just clarity, good pay, and respectful collaboration.
