Many listmembers have written in with excellent advice as to what to do as regards allowing for PD, so I will chip in with my bit by mentioning more general considerations. BTW this is the voice of experience speaking. 6 yrs ago I added a 'granny flat' to the back of my place. My mother is living there still, and my father was there until his death last December. 1. If possible the 'flat' should have its own access to the world at large, as well as access to the main house. This allows both families to maintain some degree of independence. It also means that those in the 'flat' can recieve visitors, both social and professional (doctors, social workers,etc etc) with- out automatically involving those in the main house. 2. When deciding on the placement of doors and windows try to envisage the room with furniture in it. The lounge room of our GF can only be arranged one way because it has a large glass sliding door that could just as easily have been situated in the dining area, where it would not affect the furniture layout. I blame the architect for not thinking of this, but as I was the architect this doesn't help much. Hope this helps Dennis. ++++++++++++++++++++ Dennis Greene 47/10 [log in to unmask] http://members.networx.net.au/~dennisg/ ++++++++++++++++++++
