Can I use my kitchen during the remodel?

Not the kitchen itself, but most households stay in the house. Expect to be without a sink, a cooker and usually the fridge in that room for the full six to ten weeks. What works is a temporary setup elsewhere: the fridge relocated to a garage or dining room, a microwave and a kettle on a folding table, and washing up in a bathroom or utility sink. Agree where that goes before demolition day, because deciding it after the cabinets are out is how people end up eating out for two months.
