Kanye West and Kim Kardashian sold their heavily renovated home in Bel-Air this week; the duo realized nearly $18 million in the transaction. West and Kardashian purchased the property in 2013 for $9 million.

It’s difficult to estimate the additional amount the couple parted with in customizing the house, but the Mediterranean-style of the exterior is now a vague reference streetside, and has nearly vanished from the back, where large slabs of glass define the space in contemporary terms of transparency and geometry. Big changes were afoot for the house a few years ago.

The interiors are preoccupied with scale, long, strident lines, angularity, and hard surface. The kitchen is a dream for those who crave the industrial look, with brushed stainless used liberally, down to counters and shelving. Recessed lighting in the familiar grid pattern—and the stone and concrete used abundantly throughout—adds to the very up-to-date chilliness of the home. The staircase offers a little softening influence and sculpture, helping layer the design vision a little bit.

Just this week, it was revealed that Kardashian West joined mom Kris Jenner in investing in the upscale Calabasas planned community Avanti. The pair picked up a trio of residential flats between them, with Jenner taking the lions share; collectively the pair dropped nearly $5 million for the units in the complex, which was finished last year.
