If Brad Pitt builds new cabana/deck, will you buy his Malibu estate?

Brad Pitt sure is a busy boy.

As if having six kids and a big Hollywood career isn't enough, now he's planning to build a new pool cabana and deck on his Malibu estate.

RadarOnline.com has learned that Pitt has filed plans for the additions with the Malibu City Planning Department and plans to start when he gets formal approval.

Here's the catch: According to Radaronline.com, the estate Pitt bought for $8.4 million in 2005 is still up for sale for $18 million.

Seems that he and Angelina Jolie and their brood haven't really spent much time there in the past few years.

So if you're interested, here's the extra scoop: a large swimming pool, tennis court, famous neighbors including Cindy Crawford and Leonardo DiCaprio. State-of-the art security system with cameras and infra-red alarms.

Anyone want to make an offer?
