<Features of the Winning Landscape (Green Zone)>

 Taking advantage of east-west altitude differences of the terrain, an underground parking area (Phase I and II town blocks) for residents occupies a large part of the residential area. The roof of this underground parking area was made thick enough to allow the planting of trees. The green, open relaxation space is available to the community and has the following features:

  • ・Walkways are built with water-retentive pavement to provide ease of access between each town block.
  • ・Waterways and water features draw from regional water networks, including underflow water characteristic of the Kurobe River alluvial fan.
  • ・Main green features are tall deciduous trees.

<Reasons for Award>

 The development was praised and commended for maximizing the potential of the area's (Kurobe's) natural environment, with abundant underflow water, seasonal "ai-no-kaze" winds, natural light, and greenery nourished by these elements.
