St George’s Hill Mansion Renovation and Luxury Car Garage
A distinguished St George’s Hill residence enters a new chapter, combining a comprehensive renovation and renewed landscape with a bespoke automotive pavilion for an exceptional private collection.
A New Chapter in Exceptional Living
An ambitious vision for one of Surrey’s distinguished residences, bringing together architectural sensitivity, contemporary comfort, and a remarkable private automotive collection.
Set within the exclusive St George’s Hill Estate in Surrey, this mansion is the subject of a considered transformation that brings together the restoration of an ambassadorial residence, the renewal of its landscaped grounds and the creation of a bespoke automotive pavilion designed to accommodate 18 additional exceptional cars.
The design philosophy was to encompass the private collection of significant automobiles, housed within an architectural addition conceived to sit seamlessly alongside the existing house.
Architecture with a sense of purpose
At the heart of the proposals is a substantial luxury garage, designed not as a standalone facility, but as a natural extension of the established architectural language. Its scale, detailing and relationship with the existing residence have been carefully considered to create a cohesive composition, preserving the character of the house while introducing a new luxury dimension to the property.
The result is a development in which function and design are intrinsically connected. The additional accommodation will provide a dedicated setting for 18 further high-end vehicles, allowing an extraordinary collection to become an integral part of the home rather than a separate consideration.
Rigby and Rigby have attained approval from both the St George’s Hill Residents Association (SGHRA) and Elmbridge Borough Council’s local planning authority, reflecting an important milestone in the realisation of the project, which is due for commencement in late 2026.
Rigby and Rigby have successfully discharged all pre-commencement planning conditions from both SGHRA and Elmbridge, opening the way for construction.
A collection of exceptional provenance
The automotive element is more than a matter of storage. It is an expression of a discerning collecting passion, with the proposed facility intended to accommodate vehicles of exceptional rarity, craftsmanship and historical automotive significance.
The presence of multi-million-pound collector cars brings a distinctive purpose to the architectural brief. The garage must offer the space and functionality required by a significant private collection while maintaining the same standards of design consideration and quality as the residence itself.
The comfort of the cars is paramount with stringent air handling and dehumidification designed to be felt but not seen.
Reimagining the residence
Beyond the new automotive accommodation, will be a comprehensive renovation of the main house. The ambition is to renew the residence for contemporary living while retaining the distinction and presence associated with an ambassadorial property.
The surrounding grounds will also be refreshed, strengthening the relationship between the house and its landscape and creating a more cohesive setting for the renewed residence. Together, these improvements will give the property a considered sense of continuity, from its architectural composition to the experience of moving through its interior and exterior spaces.
Performance is another central consideration. Improvements to the home’s internal environment are intended to enhance air quality, comfort, and overall living conditions, bringing renewed attention to the qualities that make a house feel exceptional in everyday use. The emphasis is on a more refined living experience, where contemporary performance complements the character of the architecture.
Cutting Edge Construction
The new automotive pavilion will utilise cutting edge screw piles to minimise the amount of excavation and concrete that would traditionally be required. This will save on construction time, cost and reduce the environmental impact that excavation and traditional concrete piles have. The structure has been designed to reduce load to minimise the amount of groundworks required. Overall, this will reduce the overall construction programme, which along with the works to the house, including the installation of a new lift and landscaping, are programmed for completion as early as Summer 2027.
A more personal expression of luxury
The approach to luxury is centred on the individual rather than formulaic: a distinguished Surrey home, thoughtfully renewed with an in-depth knowledge of the returning client, with the capacity to accommodate an extraordinary collection of cars as naturally as it accommodates the rhythms of daily life.
At St George’s Hill, this properties next chapter is defined by this balance of architectural continuity, modern performance and personal expression — a residence in which every element has a purpose, and where exceptional design is measured not only by how it looks, but by how it is experienced.
