One Location Location couple I remember snarking at were looking for a house in the country with lots of land - possibly to have space for horses - and found their perfect home, but it had a downstairs loo and they wanted space for a utility room they could put a washing machine in.
Kirstie came up with all sorts of ideas for creating utility space or moving the loo somewhere else but they just couldn't settle on a solution so they walked away from it.
I remember yelling 'noooooo you are fools!' But now we are building an extension, and guess what my biggest headache is? Yes, do we have enough room to fit in a utility area and a downstairs loo. Gah.
When I first met DH we very quickly bonded over a love of Grand Designs and mostly we agree on favourite episodes (the Huf haus of course, the charcoal burner in the wood, the young widow building her husband's dream home, which coincidentally is quite near my PILs) but there is one we don't agree on, a converted water works building which was in the middle of the woods.
I hated the building itself - the isolated location and utilitarian feel of the building made it seem really sinister and haunted - but I really hated the interior, which had wacky stuff like a Mini converted into a desk. But DH loves that one.
There was also a really annoying Location Location couple in Edinburgh who wanted a flat 'with its own front door', and eventually got one, a lovely flat admittedly, but when they redecorated, they ruined it inside and had lots of blown up enormous photos of themselves on the walls and a photo of their own bloody front door as they loved it so much.
I have to defend the programme makers a bit on the moans about the 'bolt holes' and 'pied a terres' - Channel 4 dropped Relocation Relocation several years back, and it doesn't get repeated much these days, I think. Nobody ever, ever buys the city pad anyway, so it was a pointless exercise, and I think the programme makers realised that showing a series of tiny studios and Barrett home one-bed flats that no-one ever bought was fairly dull TV.
