11m x 5m structural glass room on a second floor terrace.  The brief was “as much glass as possible, whilst retaining good draught proofing and structural strength” with the additional challenge of access for materials onto the terrace.

The solution was to design an innovative glass structure incorporating the following features:

  • The main structural strength and support was in the glass eliminating the need for surrounding support frame.
  • The doors were internal with no corner post or frame thus allowing stepped joints on the glass units to reduce silicone joint width giving the ultimate in vision.
  • The internal doors slide between the external glass and internal glass posts.
  • The positioning of the doors enabled a gutter to be fitted.
  • The profiles were 38mm, matching the thickness of the glass posts.  Four layers of pile weatherstrip have been fitted around the perimeter of the doors giving excellent draught seal.
  • The glass posts and beams were UV bonded together on site.

As the photos below illustrate the end result is a spectacular room with panoramic unobstructed views.  Click on image to enlarge.
