Yesterday, in a mad fit of DIY enthusiasm I pulled out the whole kitchen. I filled the open plan living room up with cardboard boxes so we can't sit down but do have access to a tiny annex kitchen so can still eat. I planned to drive to IKEA today to buy a long planned IKEA kitchen. However I have forgotten that the floor needs to be changed too as I have 1950's cork tiles. I want to put down black ceramic tiles; my husband says they will be freezing. My dilemma is whether to put in underfloor heating pipes now which will raise the floor height by 16 cm. This will create a step into the room and has to be done before I make the kitchen and could take weeks. So:1. What do people think about a step between rooms (the step would end up being between hall and open plan kitchen/ living) 2. Should I wait and put in underfloor heating? 3. Does anyone have ceramic tiles throughout the whole open plan kitchen/ living area and like them. I'm in a panic, my husband is seriously unimpressed and the kids think I've lost the plot. The flip side is I'm watching the sunrise for the first time in years and it's beautiful. Any advice please?
