First the former warehouse, above, on the riverside in Calstock, on the Devon/Cornwall border.
It's Grade 11 listed, fabulous views (an area of Outstanding Natural beauty), and comes with planning permission for a three-bed, three-storey home.
You don't get everything you can see in the picture - just the tall building attached to the one with the rusty shed and "living roof" (former lime kilns - you'll want to find out what the plans are for that bit).
Inside are basically three tall rooms, all looking over the river Tamar:
The property below couldn't really be called a wreck, or indeed a property. Realistically it's land for sale - which normally I wouldn't go near but I just liked the idea of what this site had been.
With the tower is a single storey building, sort of part big shed, part-offices:
It's on the edge of the rather nice Sussex village of West Ashling, about five miles from Chichester, and is on the market at £200k through Stride and Son. Details here.
At the other extreme, living space-wise, is this 12-bed former care home for sale in Foxhole, Cornwall:
I spent a fair bit of time this morning trying to find out what had happened - why the home had closed and where the residents had gone.
Aside from finding that it may have been Melbourne House and may also have been called Mother Hubbard's, I couldn't find anything about it from either the Care Quality Commission or what's left of local news outlets in Cornwall.
Anyway, wherever its residents went, hopefully it was somewhere nicer - 12 bedrooms, three bathrooms and an inaccessible garden isn't my idea of a home to live out your last days.
It's on the market via CitySales with a guide price of £250k. Details and more pix here.
