text: George and Amal submitted plans to their council for a 12-seater home cinema . They're newlyweds settling down in their dream home, and this weekend it was reported that George and Amal Clooney have submitted plans to improve their £10million Berkshire mansion - which include the addition of a 12-seater cinema. While this may seem extravagant, according to industry experts, a cinema room is now an 'expected' luxury in properties worth over £10million. Robert Osborn, co-founding director of top luxury property developer Consero London  explained: 'Home cinemas are a growing requirement, particularly for brand new or newly refurbished properties.' 'At the high level, media rooms are a valuable use of space and are expected, particularly in homes priced above £10 million. We also often include pantries or bars as an addition to support the media room.' As extravagant as it may seem, home cinemas are often a clever investment as they make use of low value space in the dark basement. Property insider, Ben Hubbard, an asset manager at OracleAMG explains: 'Cinemas are often situated in the basement of a dwelling because there is no need for natural light.' Ben estimates that cinemas can cost anything from a few thousand to £100,000 to kit out and says: 'Home cinemas can vary from a converted surplus bedroom within an average sized dwelling to a 30-seater theatre in the basement of a much larger home. 'There's a vast difference in the set-up costs depending on how far you want to go,' he said. Ben believes that the home cinema trend is growing, and having a dedicated cinema room is becoming 'important' in high-end properties. But does it ever reap financial rewards when it comes to selling? 'If one was to spend fortunes investing in a cinema equipment for an average sized family home - the chances are it will not add any value to the house as a majority of the purchasers will have different uses for that room,' Ben said.

'At the other end of the scale the more space the dwelling has the more likely you’re going to expect to see a cinema room and therefore the more value it will add. Generally though it adds  saleability factor rather than actual value. 'Set-ups can range from large plasma TVs with off-the-shelf surround sound systems in a darkened rooms to tiered theatres with cinema quality digital projectors. 'High-end cinemas will have been constructed to consider the rest of the house and can be soundproofed to prevent noise problems occurring elsewhere, which also increases the cost.'

As these images show the home cinema  is generally of a neutral hue with warm wood finishes to give it that authentic feel. But it's not only interior decisions George and Amal will have to grapple with, questions involving audiophile speakers, sub woofers, heat management systems and aerospace grade mirrors (for the projector, not Amal) will also have to be discussed at length. The Clooneys renovation plans also include upgrades to the library, gym, spa, steam room, wine cellar, boat house as well as a new swimming pool, pool house and grand terrace.
