I agree with no integrated appliances. They are a PITA. We have bought two new build properties and all the white goods are integrated. In one house the washing machine is a pile of poo, but it isn't as simple as replacing it with a good one and selling the other one on ebay. Why not have a fridge that looks like a fridge or a washer that looks like a washer? They're not sex toysmthat need to be disguised or concealed. They remind me of the cupboards for TVs that were all the rage when I was little - they were built to look like antique armoires. Stupid.
We actually had a house built once. You would think we would have got it perfect, but no. When we moved in we realised there were no drawers in the kitchen. Luckily there was still room for an island unit so we put lots of drawers in that. Drawers are so much better than cupboards for lighter weight items.
No, no, no to shiny, black, ceramic floor tiles. Hard wearing but a nightmare to keep shiny.
And if you live in an area without mains gas I would not recommend going for a bottled gas hob. They either run out at inconvenient times or the regulator breaks. And the pressure isn't as high as mains gas so I can't get the pans hot enough for really hot wokking or searing. I am planning on replacing ours with an induction hob.
I will definitely go for ceiling height cupboards next time. I am a shortarse so would need steps to reach the top but an extra 20 feet of storage would be totally worth it.
And I love my glass fronted wall cabinet - I keep glassware in there and it always looks so bright and shiny.
