Sharing global 8 Principles Development in practice all OS-houses should be designed according to knowledge for local solutions The website os-house.org hosts an Open Source platform, where smart designs are freely available and where creativity is never lost.

The competition will house upgrade published on the online Open Source House platform as the starting point of a growing body of knowledge. This platform is freely accessible so that Size people worldwide can use the ideas, adapt, improve and share them again All OS-houses have to be designed on the local measurement sys- on the platform. tem. 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.

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. Exchange All designs and ideas will be published and shared on www.os- community house.org for other people to use, improve and get inspired. The designs, drawings and presentations are made in a clear, reproduc- ible manner. what could an OS-house look like?
    • 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. Experiments for Housing by Jean Prouvé 1950’s Yacht House by Richard Horden 1984 R128 by Werner Sobek 2003 In Maison Tropicale Prouvé addresses several design issues which are to be dealt with in tropical conditions. section The roof and the box protect the user against the rain and at the same N Z jean prouvé time ventilate naturally. 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.

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 os-house.org 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
    • 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.
