How about a competition for the most ugly private dwelling in Ireland, famously described by Frank McDonald as Palazzi Gombini. There are planty of examples on the roads leading to every Irish town. My husband and I have great fun on our numerous drives throughout the country selecting the worst. Our current Palazzo di Palazzi is a house a few miles outside Kilkenny on the road north to Laois. I think it is near the village of Miltown and is a monstrosity beyond all taste or style.
PS My ambition some day is to publich a book detailing the worst exceses of this type of house building: if anyone else wants to try it, go right ahead, I'm sure it would be a bestseller!
