Jennifer Aniston and Justin Theroux are reportedly waiting until their £8million house renovations are complete before they get married.
The location of the couple's impending wedding has been in question for months and one of the most popular theories appears to be their own home.
With Jen wanting a low-key, private ceremony, the couple's £14million Bel Air mansion may prove to be the perfect spot.
But the process of making the pad "marriage-proof" is yet to be complete.
Jen, 44, is hoping to create a home in which the two of them have enough personal space and private areas - that are tailored to their specific interests - to maintain a happy marriage.
A source told Grazia magazine: "Jen and Justin have very different hobbies and interests, so it was important to her that the new home allows them to express themselves without getting under each other's feet."
They added: "Jen has created a cork-covered soundproof room which she's nicknamed 'the cave'.
"It's a place where Justin can have his friends over and they can play music and jam with their instruments, which is what he loves doing in his down time."
For herself, Jen's spent hundreds of thousands of pounds fitting her pad with a spa and wine cellar.
The source said: "Jen has had a £2m, 1,600sq ft wine cellar and a £600,000 clay-room spa built, where you can rub healing Korean clay - known for its detoxification properties - into your skin."
Imagine having that in your house!
That's not all - she's also taken the renovations outside.
According to the insider, the couple have also had a super tree house erected.
Not your usual garden tree house, this one comes in at £2m and boasts two levels and built-in speakers.
The insider added: "He loves the outdoors, so Jen built him his own retreat in the garden."
Also outside, Jen's tacked on a casual £730,000 oven, along with a drinks mixer that looks like a water feature.
We'd love a garden, let alone a fountain that makes cocktails!
With the couple compromising over splitting their time between LA and New York, Jen is keen to make their home as comfortable as possible.
Sounds very comfortable to us.
