Floating Boekhome

Blue21, in close collaboration with BOEKHOME, has developed a unique concept to “build” on water. This offers unimaginable possibilities to solve the housing shortage in the Netherlands and beyond.

Locations where in the past only (residential) boats could come, are now made possible for a much greener and more stable alternative. A living quality equal to that on land with the experience of living on the water, and at the same time fully climate-adaptive and circular.

Floating BoekHome is a unique product that has emerged from the collaboration of Boekhome, an innovative manufacturer of high-quality chalets, and Blue21 an international leader in the field of floating construction that once started as a spinoff from TU Delft.

The sustainable, factory-produced recreational homes, are largely made of wood and 100% electric. The unique and maintenance-free “Bluelands system” under the homes ensures an optimal experience of the water while providing maximum stability, of unsinkable quality and is the first floating system consisting of sustainable materials.

The Floating BoekHome sets a new standard for recreation in water areas, creating affordable and sustainable living for all.


FinEstBay Floating Development

Blue21 is very excited and honored to announce that we are now working with FinEstBay Area Development from Finland and Shimizu Corporation from Japan on floating islands in the Baltic region.

FinEstBay Area Development, Shimizu Corporation and Blue21 have agreed to collaborate on the concept and design development of Green Float Tallinn, sustainable floating islands which will be located on the Baltic Sea outside of the Tallinn city in Estonia. The floating islands will create a new maritime living, business and recreational attractions for the whole region, supporting the Helsinki-Tallinn tunnel project.

A complete media release is now available in PDF.

We are very excited and honored to be involved in this project with these two visionary companies. The planned floating islands will be the start and showcase of self sufficient floating islands for other places in the world.


Demonstrator Design


Imagine your own sustainable and affordable workspace at sea. This is what 17 European partners aim to provide by developing a standardized and cost-efficient modular island with low ecological impact.

The project consists of 4 applications of study; farming, transport and logistics hub, energy hub and living at sea. To show the potential of multi-use modular floating islands Space@Sea evaluates 3 possible business cases for various locations throughout Europe.

The three main stakeholder groups identified are governments, end-users and investors. Accordingly, we engage with governments across various chosen European countries on their level of open-mindedness towards floating developments to jointly develop recommendations on how to treat floating coastal city expansions in the future.

The project is funded by the European Commission’s Horizon 2020 program. It began in November 2017 and is setting out to make the next step in the efficient use of maritime environments. Blue21 is involved as the work-package leader.

"Space@Sea provides the opportunity to develop a showcase for a floating coastal city extension. With our expert team, we are tackling this topic through a stakeholder analysis, end-user interviews, engagement with governments across Europe, as well as, experiments with prospective inhabitants".




World Conference on Floating Solutions

Initiated and co-organized by Blue21, PAVING THE WAVES marked the 2nd World Conference on Floating Solutions WCFS2020. With enormous success, the conference attracted over 70 presenters from around the world showcasing the most state-of-the-art innovations on water.

WCFS was first initiated in 2019 by the Society of Floating Solutions Singapore with the aim of bringing international experts from the industry to share knowledge on floating solutions. Going on from the previous year Paving the Waves sought to generate conversations between the urban and the offshore, exploring how floating solutions could create a common ground for the two in the face of 21st-century urban challenges.

Watch the presentation of Blue21 given by the organizer speaker, Rutger de Graaf, below.

For more information, please visit the website of PAVING THE WAVES- World Conference on Floating Solutions.

Presentations have been recorded and made available on the vimeo of Blue Revolution Foundation.

Book of proceedings have been published by Springer and can be ordered here.

Capacity Building

Blue21’s objective is to promote floating cities as a viable solution to 21st-century challenges such as urbanization, rising housing demand and climate change. We want to improve people’s living conditions and wellbeing, create spaces which are economically viable and have a positive ecological impact- in balance with nature with the end goal of helping to conceive the world´s first floating city.

To achieve this goal requires building global awareness of the opportunities of floating development and multidisciplinary collaboration. We initiated iconic and pioneering floating projects such as the Floating Pavilion Rotterdam, Floating Ecohomes and Innozowa Floating Solar. Another core activity of our company is the dissemination of opensource knowledge and cooperation between stakeholders from a multitude of disciplines; to improve our collective understanding of floating solutions and help address the socio-economic and environmental challenges of our future. In 2013, our founders also created the Blue Revolution Foundation to create global awareness and facilitate an interdisciplinary research agenda on floating cities.

Ever since the launch of Blue21, we have been focused on the opportunities that the water provides to solve the most urgent global problems. These include fundamental challenges such as climate change, urbanization, population growth and land scarcity. We call this shift of humanity to the oceans ‘the Blue Revolution’.
