For example: make use of local materials, smart climate use, cradle- to-cradle design and sustainable energy supplies. Climate Make optimum use of location and climate conditions.

Elements have to be transportable and exchangeable with other local OS-houses. The location of the pilot project is Ghana. To create a serious design as- signment a thorough research is initiated to comprehend the situation in Ghana. At the same time further research is done on the concept itself. The Structure pilot will test both social perceptions as well as technical and economic Separate the load-bearing structure from the demountable build- feasibility. ing skin. To generate creative input for the competition several workshops are orga- nized in Ghana as well as the Netherlands. These ideas as well as existing Connections solutions are posted on the platform. So people joining the competition All connections between components and the structure and com- 2nd house can build on these ideas and be inspired by them, according to the Open ponents have to be dry and demountable. This makes disassembly Source mindset. easy and clean. Possibilities are being explored to implement the OS-house at a larger scale with a wide diversity of designs. After the pilot Enviu will facilitate local entrepreneurs to produce and Building services sell the Open Source houses in their local context. and provide a sustainable way of living. The building services are 8 OS house principles smart, safe, upgradeable and adapted to the local ecology. They can function independent from the structure and skin.

The designs, drawings and presentations are made in a clear, reproduc- ible manner. what could an OS-house look like?
  3. 3. Open Source House Case Study Design References m o d u l a r How big should a standard house be? For any modular building to be successful it has to be designed on a grid system. In architecture there is long history of modular and prefabricated building. The casestudy design aims to take the best ideas of the past and use them to make a 21st century open source house. The French engineer Jean Prouvé. In his studies in the 1950’s he experi- mented a lot with modular building and housing for the third world. One of his best designs is the Maison Tropicale from 1949.

The veranda creates outside space which is pro- rainwater storage sun boiler tected against the sun and, together with the roof, protects the box house, without the necessity of extra construction. Structure ventilation The design of the structure should make it possible to build the struc- beams which are bolted together connected with steel plates. The beam maison tropicale 1949 maison tropicale 1949 supporting the roof is made out of two parts and connected in the middle. This creates a three-hinge frame in which the beams are relatively short and can be transported more easily. The design of the frames is such that a second frame can be added on top detail grimshaw Foundation - lation of building services is much easier The house is separated from the ground level and thereby protected from animals, dirt, water, etc. By add- ing a ventilation roster the house can be ventilated with cooler air which Herman Miller assembly plant connections connection outside corner connections overview Façade: Bath 1976 igus factory, Cologne 2000 igus factory, Cologne 2000 igus factory, Cologne 2000 with Terry Farrell.

The untreated wood in the structure is reusable, recyclable and a natural material which can do no harm to the environment. houses. The panels are completely reusable for other os-houses. Climate The design is completely naturally ventilated and can, based on the context, be treated for local conditions: with insulation and ventilation. Rainwater is stored and heated on south pitched roof. Size The design is completely modular, based on a system which is easy to use in - Structure skin and roof.

And build it again of the building. Building services By centralizing the services to a central point of the house there is less space needed for service infrastructure. Furthermore the space between the roof ground is useable to place equipment to store water. All the panels are able Exchange The design will be published on the website and fully open to develop other solutions combined with this design. possibilities Design by Bo Kristiaan Janssen, Vincent van Sabben and Vincent van der Meulen
  5. 5. Open Source House International Design Competition The Design Competition starts 15th of January, 2010 and is open for team or in- dividual participation. The challenge is to design a sustainable house in an expandable way. The mod- ular construction should be suitable for future owners. 1. Sign Up for the competition. 2. Discover the OS House platform while becoming an active member 3. Start Design Competition January 15th, 2010 4. Deadline for submission May 17th, 2010 5. Award event and start Pilot 6. All designs will be published on the Open Source House platform Joining in is your chance to establish your name as an architect and to witness your design being built and sold to its new res- idents through our pilot in Ghana. The Open Source House is an initiative of Enviu and Vincent van der Meulen this still is your opportunity of becoming part of an online community of interna- tional architects that are excited about sharing solutions - able housing.
