Lakeland FlowstoneThe future of construction

Building for the next 1,000 years.


We are developing low-carbon construction materials that stand the test of time.

A truly sustainable economy relies on products that last as long as possible and have the smallest possible effect on the environment. We take that to the extreme.

One material. One process.

Many products.

Starting with the roof.

Our first products are geopolymer roof tiles: stronger, longer lasting, and laid exactly like the tiles they replace. Multiple profiles and finishes, one familiar installation.

Cement-free

No Portland cement in the mix.

No kiln firing

Lower embodied carbon from the start.

Built to last

Engineered for durability, not replacement cycles.

Made locally

Modular production, close to where it's needed.
