The East Courtyard is one of a group of three external spaces within HM Treasury. The garden offers the potential for an outdoor gathering area for larger groups of people as well as quieter spaces for individual reflection. The creation of the individual gardens is inspired by a contemporary interpretation of the classical parterre. Clipped hedges are framing the principal route and enclose the more private garden spaces and outdoor rooms. The heights of the hedges have been sculpted in a manner to restrict and reveal views of the different garden spaces. Timber benches are integrated within low-level hedges for conversation, reading or quiet contemplation. The ground plane is gently sloped to create a level change across this secondary route. A water rill runs the full length of three sides of the courtyard providing a gently splashing sound where the water enters and exits the courtyard with the gently rippling shallow water reflecting the sky and surrounding plants.
The West Courtyard provides the central focus for the refurbishment scheme of the Treasury’s office in Whitehall. The existing space, a former light well, will be filled to a depth of two metres to ground level to allow for the introduction of shade loving plants and trees. The ground plane levels form a series of terraces connected by a causeway which links the building’s major axis. The undulation in the ground plane formed from slate creates a dished surface in the heart of the space, appearing to catch the rain whilst creating a reflecting pool.
