Everything! Our kitchen is brand new
. In no particular order, these were our must haves:
I love, love, love our Miele appliances:
- Induction hob
- Steam & microwave oven
- Conventional oven
- Warming drawer
- As big a fridge as we could fit (freezer is in utility room)
- Quiet dishwasher
- Hidden quiet but powerful extractor built into wall cupboards so we have a nice line of wall cupboards above the hob
Quartz worktop
Large pan drawers
Pull out tall larder cupboard
Tambour unit (to hide the kettle and mixer)
Plenty of sockets including a pop up with usbs
Glass splash backs
Amtico floor
Peninsula has given us extra worktop, more storage and a seating area on the other side of it
We do have Le Mans things in our corner cupboards, haven't made our made up on them yet. Also have a clever corner carousel that spins around including the doors - this is way better than I imagined and has all my cans, spare jars etc in it. Also have some shallow (front to back) base cupboards with 2 shelves that are great for crockery.
Buy the best quality you can afford. Work out where you will put everything and make sure you don't forget anything. Take into account the height of your small appliances e.g. Blender. Spend plenty of time on the plan to get everything just right.
We had one firm do everything (except a bit of building work done by a firm they've worked with before), which obviously cost more, but meant less stress for us.
I love my kitchen, have fun planning and creating yours.
