Meridian House: Planning Approved For A London Townhouse Extension
Meridian House has recently received planning permission, marking a key step in the redevelopment of this London townhouse. The scheme was shaped through early engagement with the Local Planning Authority, establishing a clear and sensitive design approach that responds directly to the character of the existing house and its urban context.
The proposal involves the removal of several outdated additions and the introduction of a new contemporary wing. From the outset, the extension has been designed to remain secondary to the original building in both scale and expression. Its massing is set back from the street, reinforcing the primacy of the existing façade while allowing for a clear distinction between historic and new fabric.
A glazed central link connects the old and new elements across four floors. This intervention provides a legible break between architectural periods while creating a cohesive family home. The link is defined by a standing-seam metal roof, reinforcing its role as a connector rather than a continuation of the original structure.
Material selection was critical to securing planning approval. Roman-style bricks have been carefully matched to the existing masonry, with London Stock brick retained at ground and first floor levels. Slate roofing and stone banding reference the proportions and horizontal emphasis of the original house, while medallion detailing at the eaves, red brick quoin features, and Dutch-inspired elements provide continuity without pastiche. Windows, surrounds, rainwater goods, garage doors, and vertical louvres are PPC colour-matched to the stonework to ensure new elements remain visually subservient.
existing building. Metal cladding and colour-matched windows align with the slate and metal roof finishes, supporting a coherent architectural language. The rear extension has a reduced footprint and a hipped roof, minimising its visual impact and enhancing its connection to the garden.
Internally, the scheme is organised around a new ground-floor kitchen, living, and dining space that opens directly onto the rear garden. This area forms the centre of daily family life and acts as the point of connection between the original house and the contemporary extension.
With planning now secured, Meridian House demonstrates how a carefully considered contemporary intervention can extend and adapt a historic townhouse while maintaining architectural clarity and balance.
