Kylie Jenner Scopes Out Mega Mansion at Site of Baby Bump Pic


Kylie Jenner's full-on baby bump pic this week wasn't taken while she was on a casual stroll on a random dirt lot ... she was out with her eyes on another lavish home.

Kylie was at a construction site in Hidden Hills Wednesday, and according to building permits obtained by TMZ ... a mansion is in the offing. The building permit was issued in December, and here's what it calls for:

-- 9,187 sq. ft. first floor

-- 5,304 sq. ft. second floor

-- 2 huge garages (1,200 sq. ft and 1,468 sq. ft)

-- 1,836 sq. ft. of covered porches

-- A cabana for the pool

There's also an older permit for a retaining wall and one for the foundation. All in all, the permits value the job at more than $2.37 million ... but if she moves on it, Kylie's likely to drop way more loot. 

We broke the story ... Kylie was with her mom and BFF this week scoping out the lot -- the first time pregnant Kylie had been spotted out in months.
