Queen Anne Street follows the successful completions at Bentinck Street and Welbeck Street as well as the current project at Wigmore Street, totalling a workload of £50m.

The project involves the design and build of a six storey building plus basement, creating 44,000ft² of Grade A offices and two residential units in the heart of Westminster.

The Grade II Listed façade is retained with all structures behind four interlinked terraces demolished. A complex temporary works solution involving underpinning and temporary steel frame supports protect the façade, allowing new build works to progress unhindered.

Sub-structure works involving extensive underpinning and piles will support a super-structure of steel frame and concrete.

The open plan offices will be fitted out to category A standard and will include raised access flooring, suspended ceilings, high quality reception area, bespoke joinery, full mechanical and electrical installation and air conditioning. The apartments will also be finished to a high specification.

Our initial works include demolishing the under pavement vaults and construction of a new underground reinforced concrete box structure to house a UK Power Networks high voltage switch room and an electrical transformer chamber. This required the partial closure of one lane of Queen Anne Street, a busy through road in the heart of Westminster. To reduce disruption and inconvenience, we worked quickly to develop a robust logistics solution and liaised with Westminster County Council, Transport for London and local neighbours.

The project, when complete will also achieve a BREEAM rating of Excellent.
