We purchased a new house in 2008 and wish to extend the kitchen units. The problem is they have put an outside door right in the middle of the main wall. We never use this door as the house is on a side plot and so leads onto a road. I know a house requires two main exits out of the property but we also have the patio doors in the lounge which lead into a side garden. Can we therefore loose the kitchen door? Thanks, Glen.
