Refining the Foundations: Behind the Exciting Transformation at 24 Kinnerton Street

Nestled in one of Belgravia’s most charming pockets, the historic mews property at 24 Kinnerton Street is quietly undergoing a remarkable transformation. Behind the smart hoarding that currently shields it from view, significant progress is being made on a comprehensive refurbishment project. This ambitious undertaking seamlessly blends innovative engineering with meticulous architectural design breathing new life into a once uninhabitable property.

This mews house, while possessing inherent charm, had unfortunately fallen into a state of disrepair. However, thanks to a meticulously planned design and build programme spearheaded by a dedicated project team at London Structures and Architects TFA, it is now being carefully brought back to its former glory. Toynbee Associates has played an important role in getting the project to site, providing crucial permanent and temporary works design expertise. 

A Roof Above, an Excavation Below: Engineering Innovation in Belgravia

One of the defining characteristics of the 24 Kinnerton Street project is its engineering complexity. The refurbishment includes the significant undertaking of excavating a brand-new basement level. This addition naturally presents a range of structural challenges, particularly within the constraints of a tight urban site. To facilitate efficient and safe progress, Toynbee Associates designed a system of storey-height trusses. These temporary structures provide robust support to the existing roof and upper floors during the critical excavation phase.

This innovative approach allows for the simultaneous refurbishment of the property’s upper levels, progressing right up to the first fix stage, while the excavation and construction of the new basement space continue beneath. This parallel working strategy significantly reduces potential delays and maximizes overall programme efficiency. Furthermore, temporary bracing is being strategically installed throughout the property, reinforcing both internal and external walls while the crucial below-ground work is underway.

Intelligent Temporary Works Design in a Constrained Urban Setting

Projects like the refurbishment of 24 Kinnerton Street perfectly illustrate the invaluable role of intelligent temporary works design. Situated within a narrow Belgravia mews, the site presents inherent challenges: limited access, sensitive party walls. By carefully sequencing the construction works and an  integrated temporary works design., we have successfully enabled progress to continue on multiple fronts simultaneously, all without compromising worker safety or the structural integrity of the building, its neighbours and the road..

Our experienced in-house engineering team played a crucial role from the outset, taking over the project from a previous engineering firm that had its challenges. We worked with extsing approval and reviewing bodies from both the party wall process and Grosvenor estate to agree a new engineering design and temporary works strategy. This early involvement significantly shaped the overall structural strategy and informed critical decisions regarding construction sequencing and site logistics. At Toynbee Associates, we take pride in contributing not only to the technical design but also to maintaining the momentum and efficiency of the project as a whole.

The Bigger Picture: Revitalizing Belgravia’s Architectural Heritage at Kinnerton Street

Upon its anticipated completion, 24 Kinnerton Street will stand as a prime example of how thoughtful refurbishment and contemporary design can successfully revitalize a previously neglected building within one of London’s most prestigious postcodes. The renovated property will retain the inherent charm and characteristic scale of a traditional mews house while offering a significantly increased floor area, modern high-specification finishes, and vastly improved environmental performance. Crucially, this transformation will be achieved within a preserved façade that seamlessly integrates with the surrounding Belgravia streetscape, respecting its architectural heritage.

This project serves as a compelling testament to the power of collaborative working between design, engineering, and build teams. Bringing challenging schemes to life, particularly in central London where site constraints are significant and client expectations are exceptionally high, relies heavily on this integrated approach.
