Despite what we see on Instagram, their apps and of course the last eleven seasons of KUWTK, there's still a lot of the sisters' personal lives that we're not privy to.

Take their homes, for example. While we often see the family hanging by Khloé's pool or eating in Kris' kitchen, it's rare that we get a proper widescreen glimpse at any of the rooms.

Until now. Just today, Architecural Digest published an inside look at both Khloé and Kourtney's recently redesigned Calabasas mansions, and they are both downright incredible.

Despite having very different styles – "Khloé’s place is glamorous, which suits her style. Mine is much more restrained and modern," says Kourt – the sisters went for the same interior designer, Martyn Lawrence Bullard.

So what does a recdecorated house look like if your budget is quite literally endless? Amazing, it turns out. 

First up, here's a look at Kourtney's gaff…

That artwork/those abs:

Her stunning bathroom:

That GIGANTIC living room:

Penelope's room (complete with Hermés bedspread) and Reign's nursery:

"Both of the girls were ready for something fresh," Martyn tells the magazine, noting that Khloé's home was originally owned by Justin Bieber.

"Khloé’s house was a giant play palace built for a boisterous young man. We decided to give it some romance, bringing it back to its Mediterranean roots."

With all signs of Bieber-ness erased, Khloé's home is a decadent palace of femininity.

Can we take a moment for her shoe closet?

Not to mention that hella organised pantry, which we've seen some peeks at before:

Standard living room, draped in pure white wall hangings, y'know yourself:

Another sitting room for bigger groups:

Her bedroom:

And of course, the cinema screening room:

Can we just move in, please?
