Office Building

Four Kingdom Street is designed by Allies and Morrison practice for British Land which invested in the canal-side Paddington Central development, next to its railway station.
The building is tucked into a compact yet highly visible site on a former railway goods yard, adjacent on north to the Westway. This engineering and transportation history inspired the architecture both in the façade and interior.
The building has an unitised curtain wall, shaded on its southern elevation, opens out onto Kingdom Square, with deep, angled sun shades supported by red-oxide painted struts. The structural steel frame is exposed throughout, services components are revealed and integrated, rougher industrial materials, less often associated with commercial offices, are utilised: all contributing to reveal a personality – an office building with a bit of an edge to it.
An abstract, glazed triangular form projects outwards on its western side enclosing a series of stacked meeting pods that take in dramatic vistas over West London.
Each elevations feature vertical and horizontal aluminium fins of many shapes and sizes which lend a massive and majestic aspect to Four Kingdom Street.
The building provides over 12,800 sqm of commercial office space over nine flexible floorplates above a generous reception area and retail spaces.
In addition to outdoor terraces on all office floors, the structure is characterized by a roof garden with views over Little Venice and beyond.

BREEAM rating “Excellent”.
