STRUCTURE AND CHANCE
In 1961, architect N. John Habraken introduced the principle of 'structure and chance' (in Dutch: 'structuur en toeval'), as a celebration of pluriformity.
Following this thinking, the architect seeks active involvement of citizens in the design of their homes - from the facade to the interiors. The architect determines a plan, which the home owners customize to their individual needs and desires using a wide range of pre-fabricated, modular components. These could include walls, cupboards, stairs, bathrooms, and kitchens.
The notion of home owners as 'free actors' meant that they no longer needed to choose from fixed-plan homes, resulting in fixed-plan lives.
The Wiener Gasse 6, Vienna, Austria, realized under architect Ottokar Uhl (1984) allowed home owners to pick their preferred types and colours of windows.
Another, more extreme interpretation is giving people complete freedom to build their homes, with just the limitions of lot size and maximized height. The Scheepstimmermanstraat in Amsterdam (below) is an example of this.
The development of the Scheepstimmermanstraat in Amsterdam, The Netherlands, gave the 60 home owners free choice of style and architect (1997).
Risky? Yes. But also promising. In particular when home owners have enough budget to afford high-end architects, the results are often a joy to the senses.
Overall, I very much enjoy this line of thought as it is an attempt to marriage human design ('structure') with the principles of nature at play ('chance').
