PaddingtonCentral, London

Four Kingdom Street is the first to be completed of two office buildings that Allies and Morrison is designing for British Land at their canal-side Paddington Central development next to Paddington railway station. The building provides over 12,800 sqm of commercial office space over nine flexible floorplates above a generous reception area and retail spaces.

Tucked into a compact yet highly visible site adjacent to The Westway, Four Kingdom Street makes the most of its surroundings. Its stepped northern elevation respects the angled Westway edge while its deeply shaded southern elevation opens out onto Kingdom Square, helping to frame this new public space. 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.

The building aims to be more than just a place of work, but a place of interaction where one wants to be – to socialise, to have fun, to exercise and to relax. In addition to outdoor terraces on all office floors, Four Kingdom Street has a large communal roof garden with a bar, seating area and sports court where people from the building can come together to unwind. A generous, glazed accommodation stair encourages movement between floors with views over Little Venice and beyond. Naturally lit WC cores, on-floor showers and high quality communal changing and drying facilities provide for a healthy lifestyle. A spacious reception opens directly onto Kingdom Square and includes meeting rooms, touchdown spaces and a coffee area.

The architecture takes cues from the building’s location on the site of a former railway goods yard with hints of engineering and transportation history found in the honest expression of structural details and mechanical components at a variety of scales both in the facade and interior. The building has a unitised curtain wall, shaded on its southern elevation 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.

Designs for the building’s neighbour – Five Kingdom Street – are currently in progress.
