Local practice PDP London has renovated Eighty Strand, an art deco office building in London, restoring its original finishes and complementing them with glazed pavilions that reference the style's geometric forms.

Located at 80 the Strand, the building was originally designed in 1930 by architects Messrs Joseph, serving as the headquarters of Shell-Mex and British Petroleum until it was vacated in 2020.

PDP London was tasked with retaining the scale, grandeur and high-quality finishes of the office building's art deco interiors while upgrading its circulation and facilities to meet modern requirements.

Reconfiguring what was historically a trade entrance, the building's connection to the Strand has been completely redefined, with an existing archway leading through into a new arrival courtyard and a domed glass and steel entrance pavilion.

This entrance pavilion was developed by PDP London in collaboration with architect Duncan Mitchell and structural engineer Simon Bennett, working from concepts developed with the client Strandbrook.

"The pavilion intentionally touches the existing structure lightly, respecting the existing fabric – whilst providing a contemporary counterpoint – with a form which is expressive and reminiscent of early 20th-century architecture," explained the practice.

"The glazed elements of the roof have a frit which emulates the structural bracing at the edge of the dome, [forming] a diamond pattern that is a contemporary nod to the art deco motifs found in the building's interior," it continued.

The entrance pavilion marks the beginning of a newly-defined axis leading through to the southern Embankment entrance, with the surrounding ground floor containing communal, social spaces for tenants and a cafe.

The original stone walls and columns of the building have been restored and are complemented by polished stucco plaster, geometric glass and bronze light fittings on the walls and ceilings.

At the centre of the ground floor, a formerly inaccessible light well has been transformed into "Glasshouse Garden", a conservatory-like space containing seating, dining and meeting areas.

Framed by lush greenery and green-coloured steelwork with geometric patterns that reference its art deco surroundings, the glasshouse provides a variety of both internal and external spaces overlooked by the surrounding office floors.

"[The Glasshouse Garden] is an elegant landscaped sanctuary which sits at the heart of Eight Strand's transformation," said the practice.

"Working alongside both the MEP and structural engineers, this unique and valuable landlord space was created by altering the floor slabs...to provide level access, making this light well accessible to building users for the first time in 90 years," it continued.

PDP London has also refurbished four floors of office accommodation in the building, stripping them back to reveal their riveted columns and services, allowing flexible workspaces to be created.

Below, new basement facilities provide showering and changing areas alongside extensive bicycle parking, accessed via a dedicated entrance for bikes and vehicles along the building's eastern side.

Other art deco landmarks in London that have been restored include an office near Oxford Street converted into the headquarters of fashion brand COS by Orms, and the conversion of the Hoover Building into apartments by UK studio Interrobang.
