Underfloor heating is great because it frees up wall space if you would have had a radiator. I think coffee machines are fantastic but I was advised not to have a grinding one as they need cleaning all the time and refuse to work if you don't do it properly. I have a Miele built in Nespresso one and it is truly a star. I don't have a boiling tap. I was just worried about children being scalded. I have a tried and tested built in dishwasher. I am not particularly into experimentation if the standard design works. Mine is very quiet though and you hardly know it is on. Just a bit of a swooshing noise. A wine fridge is a luxury but it stores the wine and chills it at the correct temperature for whites and reds. As you would store the wine anyway, this seemed a neat way of doing it. I do have a larder unit but the bottom section is crockery storage with 2 deep drawers and a smaller utensil drawer above. The larder cupboard stands on the work surface with two doors, and behind these are deep draws for bread and pasta and shelves for everything else. I keep dry ingredients, sugar, flour, fruit, etc in another cupboard. I would definitely advise having an island unit as it gives much more work surface, but I know not everyone has space. People can sit at it and chat and they give a lot of extra storage. I don't think new kitchens are all about gadgets. Use of space is the key issue. Good luck planning everyone!
