Edge House

Frameless Glass Link between two buildings

At Edge House, IQ Glass designed and built a frameless glass link between the main house and entertainment block to create a walkway that protected the occupants from the elements when traveling between these separate buildings. The developer wanted to make the glass link as transparent as possible to achieve an almost invisible structure that didn’t obstruct the view of the original buildings’ facades.

Low Iron glass was used for this frameless glass link to create an exceptionally clear finish to the glass. Glass traditionally has a green tint because it contains iron oxide as an impurity which creates the green colouration. Usually you cannot see the green when looking through a pane of glass but it can be seen down the sides, therefore when designing a frameless glass installation low iron glass is specified as the side of the glass panes are not covered by a frame. Low iron glass also makes the surface of the glass clearer which is desired for listed or heritage buildings to further minimise the interruption to the original architecture.




The glass void between the two buildings is constructed from frameless glass walls, a structural glass roof and integrated frameless glass doors. Maintaining the frameless design through each element of the external walkway allows the structure to disappear into the existing architecture. The exterior frameless glass wall system was designed to be supported below the floor finishes, so the stone flooring abuts the minimal bottom channel and the glass appears to be unsupported. This sophisticated detailing gives the glass link the illusion that it has simply floated down into place without interrupting the skin of Edge House or the separate entertainment building.


The structural glass façade provides shelter to the occupants when travelling to and from these buildings while giving the feeling of being outdoors. One of the main beautiful aspects of rimless glass is the outstanding connection it provides to the outdoor environment. This glazing method is one of the most desired ways to design an indoor-outdoor living space to connect the occupants closer to the natural environment.

Within the exterior frameless glass walls, two frameless glass doors were installed to provide access to the outdoor living spaces. The two pivoting glass doors are flush with the adjacent glass and are self-closing with stainless steel rails. The doors were designed by IQ to continue the super contemporary, frameless glass aesthetic and for practical access into the garden.

Frameless glass doors are a sophisticated addition to this design are were manufactured bespoke to this project. Frameless glass doors from IQ Glass are available in extremely large sizes to create beautifully wide openings with a contemporary style. The external glass doors at Edge House were also manufactured using low iron glass to maintain the clear aesthetic seen in the structural glass panes.



The structural glass link has a modular design which makes it look like the structure has been manufactured off-site and just simply put in place. However, this finish is achieved through highly technical installation work which makes the finished result look so simplistic. When installing structural glass to existing buildings IQ Glass use their years of expertise to design the intricate channels that the give the installation it’s effortless finish.

IQ Glass worked closely with the developer at each stage of the project to ensure the works ran smoothly and the finished result was flawless. For more information about IQ’s structural glazing or for advice about a project you’re working on, email hello@iqglassuk.com or call 01494 722 880.
