We are several weeks into a new kitchen extension. We have now been without any facilities in the kitchen for a week. Up to this point they had managed to keep a working sink and oven going, though virtually no prep area.
We picked up a mini fridge at a car boot for £10 in readiness - it's great to have milk available indoors for hot drinks / cereal, rather than have to squeeze into the garage amongst all the white goods being stored there.
I have the mini fridge, microwave and the kettle on top of that, all standing on a small cupboard in the lounge - it's all been doable and not too traumatic. For the sake of 2 weeks, I've bought a load of disposable plastic cutlery, plates and cups. Washing up in the downstairs toilet is not doable in MHO.
We also put a fund away for eating out. We are near a Weatherspoons and the 4 of us can eat out for £20 ( main meal deal and soft drinks only). You get to the point where you really want a decent meal with some proper vegetables.
We have stuff everywhere ,throughout the entire house. I really think attitude of mind is getting us through. Just accept it's going to be chaotic for a while and laugh about it anyway.
We are off to stay at my mum's this weekend. I'm taking essential washing with me. Next week, I'll have to go and see how a launderette works!
Hardest bit has really been to get two teenage DS to be tidier than normal. They can't leave shoes, coats, empty wrappers etc on floor when there's barely any floor to walk on.
Good luck with your kitchen build.
