Long term, rental. Nothing big and flashy, but weatherproof and, well, big enough. Ideally something like what I have here, a self-contained cottage/granny flat type thing, in a rural or semi-rural area (eg, no street lights). Power, ADSL (as a minimum, NBN preferred), decent bathroom, no outdoor dunnies. Enough room for all the bookshelves and their contents (and future additions).
Plus enough secure storage for the kayak, diving gear, walking gear, bike, etc. Bit of a garden (esp for vegies) would be nice but not essential.
