CASE STUDY

York Townhouse

Floating Industrial Glazed Extension in North Yorkshire

At Sieger Systems, we believe in transforming spaces through innovative glazing solutions that blend aesthetics with functionality. Collaborating with Mass Architecture, we reimagined a period townhouse in York by creating a ‘floating’ industrial-style glazed extension that maximises natural light and enhances the connection between the home and its garden.

The client owned a narrow four-story terrace property, constrained by its period design and limited footprint. An existing external metal terrace was underutilised and didn’t align with the client’s vision of a bright, open space. Our challenge was to introduce a sunroom extension that would flood the interior with natural light without casting the lower ground level into shade, all while respecting the property’s historical context.

To achieve this, we supplied and installed a range of our premium products, including Invisio Structural Glazing, Sieger Casement Doors, Sieger Slim Casement Windows, and the Sieger 120 Bifolding Door System. These products were chosen for their slim profiles and ability to maximise glass area, enhancing the intake of natural light.

Our team implemented innovative design solutions that included frameless effect fixed glass roofs with silicone-jointed panes supported by steel sections. This allowed light to penetrate deep into the interior spaces. The Sieger 120 bifolding doors, with their slim profiles, created wide opening apertures, blurring the lines between indoor and outdoor areas. We also incorporated etched, slip-resistant walk-on structural glass floor panels above the existing boiler room, allowing light to cascade into the lower levels.

Overcoming the logistical challenges posed by the restricted access of the period townhouse plot, our Midlands team manually transported all structural glass components through a narrow side alley, demonstrating commitment and adaptability. Technical enhancements such as solar control coatings were applied to the structural glass to prevent overheating during the summer months. Additionally, a rain chain was integrated to effectively drain water from the Invisio glass roof, complementing the industrial aesthetic.

Project Highlight

“By meticulously engineering the structural glass and supporting elements, we crafted an extension that seems to float above the ground. Each bespoke pane was precision-cut and installed with exacting detail, resulting in a beautiful, modern sunroom.”

The culmination of these efforts resulted in a stunning, industrial-style glazed extension that appears to ‘float’ when viewed from the garden. The new sunroom fulfills the client’s desire for a bright, open space while preserving light access to the lower ground level. The seamless integration of our glazing solutions has created a harmonious connection between the home and its garden, providing a versatile space that can be enjoyed throughout the seasons.

This project exemplifies how innovative glazing solutions can transform traditional spaces into modern masterpieces without sacrificing their historical essence. By addressing the unique challenges of York Townhouse, Sieger Systems delivered a technical yet beautiful solution that exceeded the client’s expectations.
