50 Stratton Street. A comprehensive refurbishment and extension to an existing office building in the heart of Mayfair originally constructed in 2002. New terraced upper floors will use a hybrid CLT & steel structure to reduce embodied carbon and create outdoor space with a sky lobby and terrace enhancing wellbeing and green space. Re-modelled facades at ground floor will reactivate the existing ground floor commercial units and new public art, part of the planning requirements from Westminster City Council, by Hugo Dalton will be integrated into the architecture enhancing the street.

Building on S+Ts past collaborations with Hugo Dalton and experience in blending public art with architecture, proposals for a new carved artwork cornice that wraps the three street facing elevations of the building have been created by Dalton.

The public art on the existing building is by Norman Akroyd and show delicate etchings depicting the British coastline and countryside. With the blessing of Akroyd, these etchings will be carefully relocated to King Soloman Academy to ensure his work continues to benefit the people of the borough of Westminster and brings friezes from a noted British artist into the daily lives of young people.

A look back at 40 Beak Street.

Completed in 2018, this quietly flamboyant, five-storey artist’s studio sits on a prominent corner site in Soho. Replacing a derelict police boarding house, 40 Beak Street was originally designed as speculative offices above a ground-floor restaurant, but’s spatial potential opened up the option to use it as a creative space instead, realised by removing the second floor slab and leaving the hole used by the crane as an open shaft through the building.

Constructed in lustrous turquoise glazed brick that reflects the surrounding buildings and passing weather, it is a distinctive yet respectful Soho building with a chamfered corner to mark its presence and broaden the pavement below. Artwork by Lee Simmons along the cornice and reveals of the feature corner window complete this striking building.

21 Bloomsbury Street is an 86,000 sq ft office refurbishment scheme that sits in the heart of the Bloomsbury Conservation area. Originally constructed in the 1890’s the existing building has been subject to various interventions over the last thirty years.

The project sought to maintain and improve the original façade alongside creating a new sixth-floor office and seventh-floor pavilion with a communal roof terrace. The revitalised building now provides a stunning central atrium with a striking feature staircase and a café and lounge. A new rooftop café and event space provides building users with outside space and views across this historic part of London. The project incorporates a wellness studio and 174 cycle spaces.

The scheme is targeting top sustainability standards, such as BREEAM Outstanding, NABERS 5*, WELL Platinum, and Net Zero in operation, it aims to compete with the best new build offices.

The Fitzrovia is a striking mixed-use building that replaces a set of redundant and in some cases unusable buildings on an important city-centre site. The redevelopment presented an opportunity to enhance the public realm and create a building that lifts the spirits. The Fitzrovia provides 118,704 sq ft of best-in-class, future-proofed, occupier-focused accommodation with the highest standards of comfort and connectivity alongside outstanding sustainability credentials.

The principal elevations are clad in a Celadon coloured glazed terra cotta. The building is 60m long and often viewed obliquely, the modulation and rhythm of this façade adds character to the street and interest to the skyline. Throughout the day the colour and sheen of the glazed façade reflect the different weather conditions adding life and interest to a particularly ordinary part of the street.

We are working with on the redevelopment of 108 Old Broad Street in the City of London with construction partner McLaughlin and Harvey Ltd.

Strip out works have completed and the scheme is ready to mobilise into construction with a strong team in place to deliver significant upper-floor extensions, best-in-class amenity and an all-electric building strategy.

The scheme will maximise net lettable area without a significant increase in massing, reimagine under-utilised spaces, and maximise light on office floorplates with improved floor to ceiling heights. Practical completion is targeted for August 2027.

With thanks to for the film and visuals.

Before, during & after.
Stiff+Trevillion recently completed a unique mixed use scheme on a prominent corner site in London’s Notting Hill. The building had fallen into a state of decay but a radical transformation - retaining the characterful facade - has created the flagship home of ‘The Club’. The Club offers a holistic approach to health & wellbeing.

Working in partnership with .home & S+T provided the bones for this new wellness destination. With three apartments on the upper floors, the project has reanimated this landmark building.
Special thanks to for their expertise.
