Urban Reef is hiring!

Urban Reef develops bioreceptive structures for climate adaptation and biodiversity. We 3D-print these structures from dredging sediment using a 6-axis robot arm, based at RDM Campus in Rotterdam.

We are looking for an enthusiastic engineer who will be responsible for the development of our unique printing system.

You will become an important part of a small team and have real ownership in your work. We offer a startup salary, with a lot of potential to grow with the company.

Urban Reef is looking for interns!

Do you want to contribute to the regenerative city of the future? Do you have a background in material science, ecology, engineering, design or marketing? Then this is your chance!

From September 2026 to January 2027, we are offering the following internships:

𝗠𝗮𝘁𝗲đ—ŋđ—ļ𝗮𝗹 đ—Ļ𝗰đ—ļ𝗲đ—ģ𝗰𝗲 / 𝗖đ—ĩ𝗲đ—ēđ—ļ𝘀𝘁đ—ŋ𝘆
Contribute to the development of bioreceptive materials based on low-carbon mineral binders and geo-based aggregates.

𝗘𝗰đ—ŧ𝗹đ—ŧ𝗴𝘆/𝗕đ—ļđ—ŧ𝗹đ—ŧ𝗴𝘆
Explore the ecological potential of facades in urban environments, help translate these insights into design principles and collaborate with material design on bioreceptivity.

Since 2021 we've been based in the Innovation Dock at RDM Rotterdam. This former shipyard now hosts various startups and makers. We started in the smallest plot in the building, grew into our current workspace, and recently expanded to a neighbouring unit as our new production space.

Urban Reef's early structures were made from thermally hardening ceramics. This proved not very scalable, and the carbon footprint from the firing process was too high.

We are now developing a new material. We're exploring various alternative binders, aggregates and additives to find a scalable, printable, bioreceptive, low-carbon mix.

More updates as the research develops.

Facades hold tremendous potential for the urban environment for ecological and climatic challenges. This conceptual proposal shows what that could look like. Natural complexity, yet architectural integration.

We are working towards this vision, and you can still be part of it! More info through this link: https://platform.eyevestor.com/eyeventures/NL_URf?lang=en

This Rain Reef at The Green Village at the TU Delft has been installed nearly two years ago, without any treatment or seeding. The various conditions emerging from the porous morphology at multiple scales attract a diversity of species colonising the structure spontaneoulsy. The reef provides conditions, the ecosystem finds its way.

What effects do our reefs have on local temperature?

This new infrared footage clearly shows how temperature around our reefs varies. The first image shows the diversity within a reef, providing varied conditions for different organisms. The second shows the cooling effects of a reef compared to a conventional brick facade. And the third and fourth images are two exactly the same reefs, one with and one without rainwater stored inside, visualizing the effects of evaporative cooling.

These images have been taken at our pilot at the "Gele Keet" of the Gemeente Rotterdam and at our pilot with Woonzorg Nederland.
