Luciana Love all of them and we are lucky enough to have most of them in our renovated home.

The hot water dispenser was mentioned, however we got the 'updated' version (ha ha!) - the boiled water tap! Boiling water coming out the tap - an absolute necessity in Britain, where everybody seems to want a 'cuppa' every half hour. http://www.quooker.co.uk/enuk
And, as tcufrog mentioned, the under sink water filter - we stopped buying bottled water (I know, I know...) since we moved into the new house.

Also, the oven door that slides under the oven so it gets out of the way and you don't burn yourself when you handle trays or check the roast. Not that I bake or roast that much..... http://www.neff.co.uk/Files/Neff/Gb/en/Slide&HideImage.PNG

The gadget I'm most grateful for is rain sensor for the Velux windows. Two of our bathrooms have Velux windows, they get opened (by remote control) every time someone uses the loo and shut automatically when the rain starts. Again, living in Britain, it is great not to have to worry about rain getting in.

PS: I'm a terrible show-off, however I can't stage a bloody photo to save my life; and liking to illustrate threads with photos, I end up with whoever reads this looking at my broom and tea towel... sorry...
