Building

The Collections and Nitrate Buildings are buried but the central three-story Conservation Building appears above the grade. It provides natural light for the workspaces and offices with the terraced concrete arcades. This building follows the site slope to represent the open space and become a viewing garden.

You can see the stepped lawn terraces around the reflection basin on the courtyard. It reflects the shifting cloud patterns and brings the sky to the Earth. It also creates an openness sense to the heart of the facility around the site area.

In summer, the living awnings decorate the floor-to-ceiling glazing for the workspace. When winter comes, the leafless vines will allow the sunlight to penetrate deep into the building site. It will also offset the energy demands nicely.
