Four garden levels provide this Chicago residence with a variety of green experiences within a narrow city lot. An architectural addition linking garage to home created an opportunity for a new terrace off the kitchen. Decked in ipe wood, the terrace is shaped to allow views down to a lower-level gravel garden with a bubbling fountain. Above, a shaded entertainment space showcases views of the city skyline, while the highest level offers full sun exposure. The gardens are unified with flowers and plants that cascade down from above or grow up from below.
