Sounds rather like a yurt, only better because of the verandah and open area in the middle.Lately I've been fantasising about octagon houses.
Imagine this: 7 rooms and 1 garage with an open tiled area in the middle, with a wading pool. 8 gardens radiating outwards. If I really want to let my imagination go, it's got two stories, with sleeping upstairs and living downstairs. Deep, shady verandah all the way round providing for deep shady balconies all the way around.
I have no clue where the idea of this bizarre and unachievable fantasy house comes from. Probably the internet somehow.
Like a Morrocan riad, only octagonal. Imagine how cool the courtyard would be on summer evenings. Put your feet in the water. Glass of wine. Look at the stars above. If you grew pot plants, the birds might come in and do some chirping.
