We are wanting to extend by 6m (double storey) but only one half of the house. This would mean we could keep the best bit of the garden and also get an extra bedroom and bathroom upstairs. We will be obviously getting an architect on board etc, but what I can't get my head around is that we would have an L shaped house at the back, and I'm concerned it will look weird! Does anyone have this type of extension? How does it look? Any tips to tie in the old house and new bit?
