Lots of clients come to us with the aspiration to link the inside and outside of their rear extension. We do this by creating a flush threshold detail with concealed drainage channels, in order to achieve a seamless transition between the interior and exterior. Here we went one step further, by creating a void between the ceiling structure and the header of the large-format Virtually Frameless sliding doors by @1st_folding_sliding_doors. This gives the impression of the building having no definitive end point, instead merging as one with the garden.
