It looks like the so-called 'curse of Grand Designs' has outdone itself this time.
Usually the curse means the homeowners - who have conveniently forgotten that we all watched the shambles that led to the creation of their masterpiece - finding that their house is worth little more than any similar home that hasn't been sprinkled with the fairy dust of celebrity.
After all, when we've seen the corners that are cut when the budgets run out, the nasty neighbours, and the 'innovative' technology that failed to deliver, why would anyone want to pay over the odds to buy a house, albeit one whose foundations are saturated with the slavering architectural enthusiams of Kevin McCloud, or damned with his faint praise - whichever is worse.
But this week comes news that the barge, featured in 2007, and planned as an environmentally-friendly home for Chris Miller, his wife, and two children, has washed up on an Essex beach - abandoned, vandalised beyond repair and, as the Guardian put it, the ultimate post-modern architectural salute to futility.
So I was wondering if the creators of the Facebook Grand Designs drinking game need to add a new section to their downloadable scorecard in addition to such classics as:
Homeowners decide to project manage themselves.
A Kevin-to-camera monologue ends with him pursing his lips or biting lower lip.
Kevin speaks flawless Italian, French, Mandarin or Swahili.
We see footage of pouring rain pooling on a concrete slab.
The homeowners are forced to make an unplanned move intoa caravan.
Kevin has a swim in the homeowners new pool.
Project is left unfinished.
The house ends up as a giant sandcastle bucket for Essex holiday makers.
The house gets finished on time, on budget, no one has a heart attack/serious accident/gets divorced,and, with all the publicity garnered from the show, the deliriously happy couple sell it a year later for a handsome profit.
It doesn't take a genius to know that olfactory factor is vital in selling houses. No one wants a house that stinks.
In fact, bad smells top the charts of undesirable features, beating even misted aluminium double glazing, toilet carpets, and, yes, even partially-melted polystyrene ceiling tiles.
At the moment we have a rather unusual zoo fragrance emanating from our living room. Not a big zoo, you understand, not London, or Whipsnade. Perhaps more of a petting zoo, or if you're not downwind, the small animal section of a garden centre.
Because in a box in the corner of the room are nine lovely 11-day-old puppies. And though the box is regularly changed, and pups kept clean, I can see the look on visitors' faces as the doggy smell hits them when they walk into the hall.
It's a perennial problem for estate agents; the house is in a good location, the pics look great, the viewers swarm (well, OK, at the moment a few buzz past). But as they step over the very promising threshold the stench of smoke/cat pee/socks hits them, and they spend more time considering the guttering from the back garden than imagining themselves entertaining the boss in the open-plan kitchen.
There are solutions, apart from the obvious one of cleaning, including special air purifying machines (but not air fresheners - as one agent put it, nothing says, 'my house stinks and I'm trying to hide it' like air fresheners).
But I would love to hear the conversation between embarrassed agent and appalled owner as he tries to broach the problem.
'Lovely house, sir. It would be worth £500,00 if...'
'If my eyes didn't water and my gag reflex weren't activated by the noxious smell coming from years of slovenly living and that box of puppies in the corner.'
The thing with smells is that they can permeate to the extent that new carpets and a complete redecoration are the only answer. So I'm nipping the odour of my lovely puppies in the bud, and have bought a ton of bicarbonate of soda - which, according to Kim and Aggie will clean everything from a blocked drain to a blocked artery.
And when, in the spring I try to sell my house, I hope the only smell will be the sweet fragrance of success.
Twelfth night is here and, though, like the rest of the country, I'm sick to death of picking pine needles out of my socks and wrestling baubles off the cat, the streets around my home look dreary and depressing.
I hadn't really noticed how dowdy my area of Brighton was looking until everyone simultaneously unplugged their fairy lights and threw the Christmas trees, stray strands of tinsel still attached, into their front gardens.
And it made me wonder why we only dress up our homes once a year (or twice, if we're trying to sell). We slouch around like Jack Duckworth for eleven months, then plaster on the slap and the flashing earrings like Bet Lynch just for the last couple of weeks.
Maybe it's because in cities people don't tend to linger on their doorstep, and the only time we look up is to see how bad the leaking gutter has become.
Of course, there are streets nearby which look lovely all year round, and they're not in the millionaire's neighbourhoods. I'm talking about the rows of multi-coloured tiny terraces, where owners not only keep their fronts pristine, but also cultivate award-winning floral displays.
And I suspect that the effort put in pays dividends, not only in terms of community pride and cohesion, but also in the value and saleability of their properties.
So perhaps, instead of settling down to another year of grumbling about falling house prices, and ignoring the guttering, I should set a good example by making my house look as nice for the other eleven months of this year as it did at Christmas.
Now all I need to do is tidy up the back garden so I can find the ladder.
