The three winners this year were:

Ecoboulevard by ECOSISTEMA URBANO ARQUITECTOS

"An urban intervention as delightful as it is functional.

The architect has installed ‘air trees’ along a new road which represents the anonymity of edge-of-town extensions while offering a constructive proposition about their future.
The idea is simple: residents can make choices about how they would like to ‘grow’ some aspect of environmental control or modification within the created light structures, that are ‘easily dismantled and energetically self-sufficient’.

Vegetation installation for showroom TAKETO SHIMOHIGOSHI/AAE

"Mid-air nature is as unexpected as it is effective."

...The judges admired this winning design because it addressed both these conditions; by emphasising a cut between buildings with the introduction of vegetation beams (in this case covered in moss), the architect has neatly reversed the stereotype of that conventional Tokyo condition.

Wall House FAR: FROHN & ROJAS

"What happens if the plan, generally regarded as the key to good house design, is not the generator? Suppose you take various wall conditions and investigate what happens if their functions (inside and out) become the driver for the plan? The architect sees the walls of this low-budget domestic project as a series of delaminated layers (concrete cave, stacked shelving, milky shell and soft skin) into which the different spaces of the house slide.
