A roof terrace planting design for a prestigious London headquarters of an international company in Regent's Park.  The terrace, that overlooks a Mews, has no direct access from the offices and is for viewing and privacy only.  A colour scheme of silver, blue and purple `Mediterranean plants such as lavender, spiky cordylines and grasses were selected.  Clipped box spheres in polished stainless steel planters, black bamboo and bespoke black obelisks introduce geometry and height.
