SD20 Slim Sliding Doors and clerestory windows help create a lightweight extension to Victorian property

The Victorian Weathered House, situated in Sydenham, was remodelled and extended to maximise living spaces and make better connection with a garden. The back extension now visually resembles a lightweight pavilion, offering the owners a seamless connection with the garden. That is why the choice of glazing for that project was of particular importance to the owners and the architects, as it was to help achieve that lightness and airness in design and help illuminate interiors.

Our Slim Sliding  SD20 system offered the slimmest interlocking frames, and an opportunity to install an open corner design without the need of installing a post to support the structure. This solution paired with the flush threshold created a seamless indoor-outdoor link between the house and the garden spaces. The doors feature minimalistic, slim lines and frames that enhance its architectural aesthetics and add to the lightness of the design!

These large swathes of glass with minimal aluminium frames fit perfectly into the lightweight nature of the entire design. It was important to control solar gain that is why the the doors were fitted with the solar control glass to achieve u-value of 1,4 W/(m2K).


To add even more airness and height into the interiors, a wrap-around row of clerestory windows was placed below the roofline. Now clerestory windows help to illuminate space with even more natural light.

On top bespoke large swathes of glazing the property was also fitted with additional set of single CorVision sliding doors, large fixed picture window, and a set of Cor70 Hidden Sash with hidden hinges and tilt and turn function.

The project is conceived as a lightweight pavilion that sits to the back of the house, touching it lightly. The existing rear wall of the house remains clearly legible, forming the backdrop to the new spaces which sit in front of it. A crisp oxidised steel frame defines a kitchen, dining and external terrace spaces below.Selencky Parsons
