Here's a tour through an apartment that you can never, ever stay at. Developer blessod built the entire thing in the Unreal Engine (software that creates simulations), so it's about as "real" as all those ideas on your board.
It's frankly pretty staggering — though as Fast Company points out, the IKEA catalog basically does the same thing, which might be why it feels like you could never actually recreate their kitchens.
Take a look around (just don't get attached):
And while you're at it, check out a similarly built virtual apartment in Paris.
