Hello!
Georgia, I think an in-frame kitchen has a frame on the front so there's a slightly smaller opening for the doors/drawers, but they do look great. This explains it better than I can: advice.diy-kitchens.com/customer-questions/what-is-an-in-frame-kitchen/
All DeVOL shaker units come inframe, and the company I'm using (Foxtow Shaker Doors) will do this too, but I'm opting for normal doors in the shaker style.
Re suppliers/budget, the carcasses are Ikea (£2.7k), Foxtow Shaker Doors (£6.7k) for all the doors, drawer fronts, panels etc. That's oak, colour matched in Farrow and Ball (the most expensive option they do but still very reasonable!). The hardware is from Armac Martin (£1.3k)! An absolute fortune but that's for around 40 knobs/catches/latches and in an antique copper finish which is much more expensive than chrome, burnished brass etc. Appliances are just under £6k for a single oven, combi microwave, warming drawer, induction hob, wine fridge, dishwasher, integrated fridge freezer and undercounter integrated freezer. Mostly Siemens and Neff (with a lo-hot of shopping around/research/haggling). Then £500 for a marble tiled splashback, white quartz worktops should be £2-3k. So all in that's around £20k, not going super high end but definitely not scrimping. Have a look on page 3 of this thread for a pic I posted of what that should get. Overall I think the handles, splashback and worktop will make it look much more expensive.
Good luck with your extension project! We started our extension last June and it's still going. The timber frame went up a week after DD2 was born (although that was the easy part!).
Barbie, how did the viewings go? I love a nosey on Rightmove (usually very expensive London properties that are waaay out of my budget). This one is so expensive: www.rightmove.co.uk/s6p/71347145. I know the location really well and it's super high spec but I can't get over the price! And it's effectively a terrace. I'd much rather a nice detached Georgian house in Petersham. Because I can obvs afford something like that.
I guess it's pretty typical of house prices now though and I think 2 bed apartments in the Star and Garter development were going for around £2m. Also, is anyone else like me and not a fan of the decor in prime London properties (like the house I linked to and other places in Belgravia, Mayfair etc.)? I can't put my finger on it but it's all a bit too polished.
Oh, and good luck with your viewings Mum2015! Let us know how they go.
Lastly, all going well here. The concrete floor has just been polished. We can't walk on it for 48 hours and I'm dying to get in there! Oh, and the doors arrive very soon. We haven't even started the unit construction, but I can update and let you know what I think of the finish/quality etc.
