Glazing Vision’s Pitchglaze Roof Window provides a sleek finish and abundant daylighting on a high-quality house extension in Cambridgeshire.


Glazing Vision has worked with Cocoon Architects to provide outstanding daylighting in this visually striking domestic extension and remodelling project located within a conservation area in Ely, East Cambridgeshire. The Pitchglaze in plane landscape roof window completed the transition and smooth design of the kitchen in the newly renovated house.

Originally constructed in the mid-Victorian era, the layout of the home was dated and in need of modernising. The kitchen and dining area were secluded from the spacious garden due to the adjacent bathroom, making them feel cramped and dark. Responding to the brief, the architect moved the bathroom to the centre of the building to create an airy and light-filled kitchen.

Sliding doors complete the passage from the kitchen to the garden providing daylight and ventilation. Not only does the renovation of the kitchen provide a more relaxed atmosphere, but it also opens up the space to enable the client to entertain in the garden. The mono-pitched extension utilises a vaulted ceiling layout, while maintaining a low profile for the benefit of the neighbours.

Colour-changing LED lighting has also been introduced along with a separate jacuzzi bath, creating a ‘spa-quality’ feel. The kitchen includes tiled flooring, and timber beams are prominent on the ceiling providing a rustic feel.

Despite the new level of daylight, the homeowner wished for more. The pitched slate roof was perfect for a three-metre square Glazing Vision Pitchglaze Roof Window. Located beneath the roof rafters, and in line with the slate, the Pitchglaze eliminates the need for an external upstand. Connecting the kitchen with the outside, the roof window also provides views of the mature trees and bushes in the garden. Added to this, the Pitchglaze provides excellent thermal performance with a double-glazed specification incorporating a laminated inner pane. The finish produces a smooth external aesthetic – an important factor, given that the master bedroom overlooks the pitched roof.

“The detail at the perimeter allowed us to install the roof window with a ‘frameless’ view internally, but as the extension is single-storey and the roof is viewed from the master bedroom window, it also looks fantastic against the slate roof,” says Matt Plummer, Director of Cocoon Architects. “The product looks fantastic and performs brilliantly too. The technical team were excellent during our selection process. Being a local company, we felt confident that should there be any issues it would be dealt with swiftly. In the end the whole supply process went as planned with no issues. We are looking forward to working with Glazing Vision again on future projects.”

From the original drawings to the final installation, the project was completed with precision, with Cocoon Architects transforming what once was a dated house into a modern home.
