Young architects worldwide create solutions to urbanization in the “City Above the City” competition.

Metsä Wood’s competition inspired architects worldwide to design wooden extensions to city centers. Entries from 40 countries proposed wooden solutions to the challenges of urbanization. Winning designs were made to New York, Shanghai and Tampere, Finland.

Architects from 40 countries created their Plan B to urbanization using wood (Kerto® LVL – laminated veneer lumber) as the main material. The task was to design a wooden extension to an existing urban building. The entries were designed to 69 cities worldwide, including Sidney, Shanghai, New York, Berlin, Paris and London. The competition was organized by Metsä Wood.

“Construction must become sustainable and cities must stay livable. I am happy that so many architects share this view, especially the younger generation”, says Michael Green, from MGA architects, Chairman of the Jury. “Entries were innovative and added value both to the building and the community ”.

“The designs were realistic and demonstrated a good understanding of LVL as a building material”, says Stefan Winter, Professor at the Chair of Timber Construction and Structural Engineering at the Technical University of Munich. “Because of lightness and fast construction time, Kerto LVL is an ideal material for this challenge”.

“Building wooden extensions to existing communities can be a significant solution to urbanization. Instead of demolishing communities, we could to enhance them”, says Mike Kane, Architect and Senior lecturer at London South Bank University. “This competition should be seen as a catalyst for the future debate on sustainable and progressive cities worldwide.”

Winners were awarded in two categories: Small and large scale intervention. The total sum of prices is 35 000 €.

We received over 170 entries and all the designs are now presented on our website. The entries are categorized the in different themes. You can for example take a look at the overwhelmingly futuristic designs or see how entrants have turned urban roof tops into green cities. You can also filter the entries based on the country.

The demand for housing in urban areas continues to grow. Unused land along railway lines, similar to land previ-ously used for commercial and industrial purposes, is being developed as building plots in inner city areas. But the available land is limited. In order to provide housing space, densification in the form of filling vacant lots or the more efficient replacement of buildings is being promoted.

The city of Bonn, for example, shows a total ground area of residential buildings of 6.6 million m². Of this an (unbelievable) 27% could have an extension built according to the survey. This way, more than 20,000 apartments with an investment volume of more than EUR 4 billion could be created in the former capital.
