We are proud to contribute to the next chapter of 55 Baker Street, London, supporting the second major retrofit of this iconic Marylebone landmark through our façade consultancy services.

Designed by Make Architects, 55 Baker Street is a is a ten-storey office building located in the Marylebone district of London. The 1950’s property has already undergone one round of refurbishment and redesign of the two blocks connected with a glazed screen enclosing the courtyards.  

The second round of refurbishment is proposed now to replace the majority of the existing glazed areas across the building, along with works to extend the property by one-two storeys at the roof level. Additionally, the architectural intent is also to implement natural ventilation through the integration of operable vents in a mixed-mode ventilation scheme.

The scheme will retain the monumental glazed façades introduced by Make Architects in 2007, led by founder Ken Shuttleworth. By retaining 70% of the original building and prioritising energy efficiency, the design team has saved 2,000 tonnes of embodied carbon and developed a cost-effective scheme that’s given Baker Street new office, residential and public spaces, plus a reinvigorated streetscape.

Working closely with London & Regional and in collaboration with Cundall, Wintech is providing RIBA Stage 2 and 3 façade engineering services, including strategic options appraisals, concept design support, thermal and structural assessments, and a performance‑based specification to aid the upcoming tender process.

This project demonstrates how innovative design and engineering can breathe new life into existing structures while meeting sustainability goals.
