Domenico.CC

A low-cost, open-source geodesic dome system

Developed by Colaborativa.eu
in collaboration with Fab Lab Limerick

Collective spaces

Why geodesic domes?

People need collective spaces to gather for group activities and social support. Instead of waiting years for the financial resources and political support to arrive, we propose to take matters into our own hands by self-building temporary collective spaces.

We believe geodesic domes are highly suitable as collective spaces. They are strong and light, covering big spans using small and light elements. Thanks to latest digital fabrication technologies and beside the complexity of its elements, geodesic structures can be self-built in local Fab Labs at an affordable cost.

Domenico.cc

Geodesic Domes for everyone

Domenico.cc is a project aiming to enable everyone to self-build their own collective space using geodesic domes and following the principles of low-cost, local digital fabrication and open source.

During the past two years we have developed several Domenico.cc prototypes. The first one was based in bamboo struts and 3D printed bio-plastic connectors and resulted in a 6,5 meters dome. The last one uses waterproof cardboard tubes and plywood connectors allowing bigger domes. Our latest Domenico.cc files can be found here under an open licence.

We are making good progress with each iteration and are pretty excited since our next prototype will be at Maker Faire Rome in October 2015!

Technical Specifications


Our latest 3.0 Domenico.cc version has the following features:

  • Design based on 3V 5/9 Fuller-Kruschke method.
  • 165 waterproofed cardboard tubes and 61 CNC cut fabricated plywood connectors.
  • Span of up to 14 meters and 150 square meters covered area.
  • One day assembly with non-specialised training needed.
  • Low cost of approximatelly 10€ per square meter.

Domenico.cc is designed to be built in a Fab Lab using local resources only.

Questions & Answers


Why open source?

We want anybody to be able to build strong, affordable and locally made geodesic buildings. By open-sourced it anybody can contribute to the development, right now we are collaborating with universities, institutions and individuals.

How do we fund the project?

We are committed to keep Domenico.cc open source so we finance the development by doing workshops, talks and selling related products like this lasercut 50cm geodesic kit. Thanks for your support!

Is cardboard a suitable construction material?

Cardboard is a fantastic material: strong, reciclable, manufactured using very little energy and globally available. We are inspired by more than two decades of research by architect Shigeru Ban.

Do you sell the connectors?

If you want to build a Domenico.cc but you don't have access to a Fab Lab then we can cut the connectors for you. Drop us a line at .

What is the development roadmap?

Right now, we have a well tested, strong and easy to build main structure. Recently, we have been working in a deck and an inflatable cover. First prototipes of these solutions are planned for the first quarter of 2016.

Support Domenico.cc

By buying Domenico Nano!

We are developing a series of digitally fabricated products to help supporting the development of Domenico.cc.

One of our products is Domenico Nano, a 55cm diameter geodesic sphere which is digitally fabricated in a Fab Lab and made of high quality birch plywood. This educational kit is intended for families, students, designers or anyone really who is curious about geodesic design.
