The renovation and addition employ a series of layers inherent to the original architecture that creates a dialogue between old and new. While a majority of the new program occupies the existing building, the centerpiece of the project is the dramatic addition to the north, oriented on the axis of the new entry garden to the Botanical Garden. A transparent, largely glazed secondary lobby space separates the new addition from the existing pavilion providing a buffer to the garden shop and serves to reorient the user along the new garden axis.
The architecture of the new building sits comfortably among the many existing garden conservatory buildings in both scale and materiality. The interior architecture of the garden shop is enhanced by an unexpected double-height space flooded with natural light by north-facing glazing and a continuous roof monitor.
