She was spotted walking around a construction site with mum Kris and best friend Jordyn on Wednesday.
But Kylie Jenner, 20, wasn't using the rubble-filled site as a good place to stretch her legs - instead, she was reportedly overseeing her new property being built in the Hidden Hills of Los Angeles, a gated community where she already owns a home.
According to TMZ, the expectant mum is set to house her first child in a decadent mansion, with building permits suggesting the value of the job to be over $2.37m (£1.91m).
The site obtained the building permits to the impending property issued in December, which reportedly boasts a 9,187 sq. ft. first floor and 5,304 sq. ft. second floor, with two massive garages attached.
The permits also suggest there will be a 1,836 sq. ft. of covered porches as well as a cabana for the pool. Older permits for a retaining wall and foundation were also cited, with adjustments to the building likely to cause the $2.37m cost to rise.
Kylie previously owned a $1.7m (£1.20m) decadent mansion in the exclusive Californian area, which other stars, such as Miley Cyrus and Drake call home.
