Mixed use development using a hybrid of steel, concrete and composite structure

The building, which combines three separate addresses and replaces two existing post war buildings.

The block facing Baker Street provides over 7000m2 of office space. To the rear, two residential blocks, one facing George Street and the other facing Portman Close, share a central courtyard garden.

A screen façade of precast columns and spandrels wraps around the office and retail section on the Baker Street side of the development. The width of the columns that form this screen is exactly equal to the depth of its spandrels, 350mm, and this screen frames glazing that steps in and out, sometimes flush with its outer face and sometimes set back. At ground and first floor levels, concrete columns help to form a street level colonnade.

In certain places the façade reveals the logic of its structure. In other places the 4.5m x 3.68m elevation grid is intentionally lost in the pattern of vertical precast concrete screen elements, of which some are dummy columns, while others coincide with the stanchions.

Materials used for the residential blocks relate more closely to the developments' immediate neighbours.
