This chic city garden provides a cool and elegant space for entertaining. An awkwardly shaped, shady garden has been transformed into a split-level design, which pivots around a set of architectural steps. The steps also provide informal seating, wrapped around a striking water feature where water trickles over a large slate cube. The entire space is flanked with fastigiate Hornbeams and Buxus ‘polka dots’ punctuate the cool, under-planting.
