At the same time, the existing snail-shaped hothouse becomes a new botanical knowledge centre, and in designing the interior and exterior landscape it has - just as with the architecture - been important to bear the existing architectural values in mind.

The project unites architecture, engineering and landscape architecture so closely that disciplines overlap and become inseparable: i.e. in a hothouse, landscape architecture also becomes interior design. The hothouse integrates a natural level difference of 3 meters via interior terracing, including rice plants, and sinuous paths around an interior pond-landscape with Victoria water lilies and mangroves.

The double curved base originates from the existing greenhouses, meanders with the surrounding landscape topography, forms the base of the new tropical hothouse, and becomes a retaining wall that encloses the court for storage and containers in one sweeping movement. A new courtyard between the new and original Palm Houses used for outdoor seating and dining, and is paved with in-situ cast concrete in a triangular pattern so that the surface appears directionless. The triangular planting beds are planted with single species, in contrast to the diversity of the botanical collection.
