If you (hpothetically) had the money, would you buy a house with a swimming pool? If so, would you prefer it indoors or outdoors? How much do they cost to maintain? What about a tennis court?
Friend is househunting and not looking for a house with a pool, but has found a cottage in her perfect area which has an outdoor pool. The pool is putting her off (which I think is mad becuase it is otherwise exactly what she is looking for - not to mention that it will make visiting her even more enjoyable!), but she says (1) she will never use it given weather in this country, and (2) she suspects it would be expensive to maintain.
It got me pondering though and I suspect she is right that the weather means it will not be used much. I would love an indoor one though (not at all realisitic given we are in central London!)
