A brown glass-fronted splash back gives the Vision a very distinctive appearance, and we've put the oven vent well out of the way behind the grill to avoid dirt traps.

The construction must be free from dirt traps (so any form of framed system with infill panels will not be acceptable as the construction forms dirt traps which can never be effectively cleaned).
