SQUARES FOR TOMORROW
Building for tomorrow – affordable, simple,
future-proof.
fu.
Rising construction costs, scarce resources and environmentally harmful building methods are shaping the construction industry worldwide. That is why, in our Sustainable Building Lab, we are developing modular, recyclable building systems that are deliberately designed to be low-tech for universal use.

Our Principles

affordable
Modular systems significantly reduce material and labour costs – without compromising on structural integrity or service life.

simple
Can be used without specialist tools or heavy machinery – from trained professionals to DIY enthusiasts.

future-proof
Dismantlable, reusable, CO₂-sequestering – built for a genuine material cycle rather than throwaway architecture.
Our Building Systems
We are product visionaries.
Two innovative products have already emerged from our sustainable building lab: the BONO.BLOCK and the RE.CK.

Modular timber wall system
Patented interlocking timber modules that can be assembled into load-bearing walls without the need for heavy machinery – even by untrained personnel.
- Dismantlable and reusable, CO₂-sequestering
- Hollow chambers can be filled as required
- Suitable for self-build
- Ideal for communal buildings, blocks of flats and cluster housing.

BONO.BLOCK System House

Building block made from construction waste
An earthquake-resistant, mortar-free load-bearing building block made from up to 97% recycled construction waste – suitable for laying by hand and being industrially scalable.
- 11 kg — easy to handle
- Earthquake-resistant tongue-and-groove joint system
- Supports loads through its own weight and friction, without the need for mortar
- Ideal for reconstruction and disaster-stricken areas
- AI-powered microfactories for local on-site production
