We cannot exactly call these photographs an excellent advertisement for our work. The shutters / grilles are shown surrounded by dust and scaffolding. However, we installed these two large and unique, massive rolling grilles in a Kings Cross residential development this month. These were specified by a London architect on the basis that they can roll into a very tight size around a tubular motor barrel. SDI were commissioned to design and install them because - well, only we could achieve this kind of custom job. When the house is finished they will be photographed again.
