Architect\u2019s view<\/h3>\n
At Marylebone Place, we took on the challenge of balancing preservation with modern innovation, all while adding thoughtful touches that contribute to the vibrancy of the neighbourhood. The project involved the careful restoration and of a 1930s neo-Georgian building, retrofit a 1960s extension, and redesigning the car park at the rear. The goal was to create a cohesive and contemporary space that honours the site\u2019s history while enhancing its surroundings.<\/p>\n
A key achievement was retaining 85% of the principal building\u2019s substructures, frames, and facades, saving 7,515 tCO2e in embodied carbon in the retained structure. The 1960s concrete frame building was reclad using an innovative pre-cast brick system, with panels assembled off-site in bespoke patterns featuring seven different brick types. This approach not only allowed the building to integrate harmoniously with the local architecture but also added a layer of texture and detail that enriches the streetscape. The perforated brickwork discreetly hides structural columns while inviting natural light to filter through, creating a play of light and shadow that adds life to the building\u2019s fa\u00e7ade.<\/p>\n
Studies showed us that the existing car parking structure on a mews service road could not be adapted or retained, but we remained committed to a sustainable solution. The resulting building is a boutique office space constructed from lightweight glulam and cross-laminated timber, with exposed timber joinery that adds warmth and character to the interiors. This timber structure saved an additional 19 tCO2e of embodied carbon compared to a concrete alternative (using 50% GGBS) and the use of prefabricated elements helped reduce time on site, minimising disruption to the neighbourhood.<\/p>\n
This mews building features brightly coloured loadbearing glazed lava stone bricks\u2014a modern interpretation of traditional materials. These custom-shaped bricks don\u2019t just serve a functional purpose; they bring a playful and dynamic quality to the building\u2019s faceted elevation, adding a splash of colour and visual interest that delights passersby and enlivens the local area.<\/p>\n
Collaboration between our architecture and interior teams was key to developing a cohesive narrative that extends from the exteriors through to the interiors. The reception area is designed to be a welcoming and sophisticated space, using durable materials that reference the site\u2019s history as the former headquarters of a garment manufacturer. It\u2019s a place that invites people in and reflects the building\u2019s role as both a functional workspace and a contributor to the neighbourhood\u2019s fabric.

Client\u2019s view<\/h3>\n
Marylebone Place, a dated but characterful 1930s office building with a 1960s extension and car park to the rear, was ripe for redevelopment. Beltane Asset Management and TPG Angelo Gordon saw the building\u2019s potential and set out to bring the tired structure back to life while minimising embodied carbon, embracing the circular economy, introducing openable windows, incorporating urban greening, and promoting sustainable transport.<\/p>\n
We have worked closely with Fletcher Priest Architects and the wider design team to sensitively reimagine the building, retaining the elements that make this building special and preserving its historic character, whilst bringing the building and its office offer into the modern day.<\/p>\n
Sustainability was central to our approach. By reusing the majority of the existing frame and substructure, the development saved significant amounts of embodied carbon, reduced on-site time, and minimised disruption to the neighbourhood. The building is now fully electric, with openable windows that provide mixed-mode ventilation, ensuring a healthy and comfortable environment for its occupants. It meets current and anticipated energy, health, and wellbeing standards, and is designed for resilience and durability, ensuring a long and sustainable future.<\/p>\n
The resulting workplace is fit for the 21st<\/sup> century, whilst retaining the essential character of this historic building. With its extensively landscaped terraces and rooftop views over London, Marylebone Place now stands as an exemplar of retrofit and innovation in the heart of the city.<\/p>\nClaire Brinson, partner, Beltane Asset Management<\/em><\/p>\n<\/div>\n\n
