Glazed extension for grade II listed West London villa

Behind an original period homefront (circa 1850), hides one of London’s deepest and largest domestic basement projects under a grade II listed period villa. Situated in the heart of fashionable Notting Hill and Westbourne Grove this beautifully re-built detached gem had been re-invented by the West London based architectural and interior design practice Newman Zieglmeier, who reimagined this family home using a blend of traditional and modern aesthetics to create an innovative light-filled luxury space of the highest standard for its busy owner.

This extraordinary low built six bedroom villa has been meticulously modernised to a state-of-the-art multi-level luxury property with soaked in natural light interiors.

Southern Windows was approached to manufacture and install large swathes of architectural glazing and glass box structures for this modern external and basement extension – to create a perfect indoor-outdoor experience.

A light and minimalist side extension with lots of glazing and minimal frames was appropriate for a high quality existing abode. Large scale glass box gallery now inconspicuously wraps around the garden enhancing the existing dwelling. This stunning architectural gallery design has been achieved using our minimally framed structural glazing. Large swathes of modern, full height floor-to-ceiling sliding glass panels with minimal aluminium frames, low threshold and clever corner solution, merge with a structurally glazed roof to deliver a pavilion style glass box side extension, transforming part of the garden into a private art gallery. This wow-factor, high-performance, L-shaped gallery is a lightweight structure and has a minimal visual impact on the neighbouring properties.

This, hidden behind the original villa, gallery is only part of this transformation. A bold new addition of a basement extension maximises the footprint and creates a luxurious and tranquil living space for the owner. Sinking the extension into the ground, in this trendy, West London location, creates a low-profile, minimal impact extension with spacious, multi level basement, housing a cinema, swimming pool and rooms – all hidden below ground – with plenty of visually interesting and minimalist features and industrial touches of steel-looking Crittall-style internal glazed doors. This light-filled extension comprises of a series of interconnected spaces that allow for plenty of natural light to enter, bounce around, and seep through the different floor levels.

Choosing the right glazing was an important design decision, as it allowed to seamlessly join new with the existing, maximise the space, and fill it with plenty of natural light, without compromising on thermal performance, and at the same time, create a stunning modern home with the use of minimalist design principles.

As this is a grade II listed property extending it could pose a challenge, however not for a skilled team of architects and their building contractors Zibi and Jack. Together they’ve been transforming properties, offering a full design and build service that brings together an innovative approach and the practical facilities to realise any design concept. The unique combination of Newman Zieglmeier’s vision and attention to detail and the use of minimalist glazing of a large scale, transformed this property into an architectural masterpiece.
