This isn't really a House Hunting Horror, as much as a greedy developer trying to squeeze too many 'houses' into too little space.
I live in a city that's reasonably expensive and house prices have rocketed, so space is at a premium. DBF and I spotted a new development that looked lovely, and was very reasonably priced. First impressions were good (clean, modern development, with a shared garden and on a nice road), and then we looked at the flat.
It was furnished as a show complete with artfully laid tennis rackets and poloshirts, and the downstairs was lovely - kitchen dining room etc.
Then we went upstairs.
There was so little space in the 'Master' bedroom, that to get in, you had to climb over the edge of the standard double bed, and then end up trapped between the door and the wardrobe. My mum got trapped.
Each room (2 bedrooms, bathroom, and top of the stairs had a door that opened outwards. Which was fine, except that the landing was so small they all opened into each other. I got trapped in the bathroom, and with a lot of banging we did eventually work out how to get the doors to close so that I could get out. Such a pity - and even the estate agent commnented that if only they had chosen to fit 3 houses in the space rather than 4, they might actually be sellable. Last time I checked the price had dropped by 10k.
Then there were the usual houses with a)mould covered everywhere b) floors sunk several inches below where the wall ended, c) a pay by coin electricity meter, and d). Dolls heads, plastic skulls and broken glass 'decorating' the walls of the garden.
We nearly bought a house with a greek frieze on the wall, but darn it it sold before we put in our offer!
