The showbiz power couple are said to have forked out the huge sum to make changes to the outside of their Los Angeles home by having a firepit, barbeque, terrace and an outdoor kitchen complete with a dishwasher, sink and ice maker installed.

According to Radar Online, the pair - who have three children, Mason, five, Penelope, two, and six-week-old Reign - filed permits listed under Kardashian's Georgette Roberts Trust with the Building and Safety Division of the City of Calabasas.

The couple purchased the plush pad, which boasts six bedrooms, nine bathrooms, a gym, a games room and a music room, from former American footballer Keyshawn Johnson and he previously splashed out $1.5 million on a detached garage.

Like, Kourtney, 35, and Scott, 31, the ex-NFL player also improved other areas of the home's grounds by spending $66,000 on a swimming pool and $30,000 on privacy walls.

Kourtney is no stranger to making home improvements either and previously demanded her sister Khloe Kardashian pay her $25,000 for helping to design her sibling's new abode, which is also in Calabasas.

Speaking on an episode of 'Keeping Up with the Kardashians', she said: "I haven't found anything grand enough yet for this," before adding: "So I'm gonna keep looking. All we have left to take care of is I just need to have my cheque sent..."

But Khloe was less than impressed and hit back: "Mmm ... for $25,000? You must be out of your mind. Get over yourself."
