Private cinema in Chamonix:
a bespoke dedicated room in a chalet
At the foot of the slopes, in an exceptional chalet let out as a high-end holiday rental, we helped build an 18 m² private cinema room in Chamonix. The owner was mid-renovation when they contacted us. We supplied the layout and execution plans so their tradespeople could build the partitions and install some of the equipment, then we stepped in on site to fit the acoustic panels and configure the whole system. That's how a real private cinema gets built in the Chamonix valley.
An 18 m² private cinema room in a Chamonix chalet
The room is just over 18 m², enough to fit a real dedicated room with several seats and a proper viewing distance from the screen. It's a comfortable size for this kind of project in a Chamonix chalet, provided the room is treated in the right order: structure and soundproofing first, then acoustics, then equipment and calibration. Nothing dramatic to film in the early steps, and yet they're what makes all the difference in the end.
Soundproofing a Chamonix chalet to push the volume without disturbing the house
The room is fully soundproofed. The partition was built with a double layer of plasterboard with a heavy viscoelastic material sandwiched inside, then reinforced with Fermacell board. This structure decouples the wall and prevents parasitic vibration when the bass kicks in. It's a fairly costly step, especially with the Fermacell, but it lets you push the sound to the limit without anything carrying elsewhere in the house. In a timber-framed mountain chalet like those found throughout the Chamonix valley, this care on the structure changes everything.
Acoustic panels and stretched fabric: the room's finish
The whole room is dressed in stretched fabric, and we add suede-finish acoustic panels filled inside with materials such as recycled denim. They're very thin, three centimetres, and yet extremely absorbent. On the front wall, a double layer of felt already limits the first reflections near the speakers, so the panels don't need to be spaced off it there.
Spacing the panels off the back wall to absorb bass
On the back wall, it's different. Low frequencies strike hardest at the rear, and even with plenty of felt, a panel held off the wall by roughly its own thickness creates a double absorption. The sound passes through the panel, hits the felt and the wall, comes back filtered, then gets stopped again on the way out. Space the panel off the wall if you can — it's purely mechanical and it works better.
The picture: a Sony projector and an Infinity acoustic screen
The picture comes from a Sony VPL-VW590ES projector (now replaced by the VPL-VW5000ES), delivering deep blacks and a bright 4K HDR image while staying very quiet. It projects onto our made-to-measure Infinity acoustic screen, with a base of nearly three and a half metres spanning wall to wall. The screen is perforated to let sound through from the speakers placed behind it. In the dark, the result is striking: the black level is so deep the screen looks like an extension of the wall.
Dolby Atmos 7.2.6 sound by Bowers & Wilkins
The sound system is a Dolby Atmos 7.2.6 setup in Bowers & Wilkins. Three CWM7.3 speakers form the front stage, hidden behind the screen and fitted with rear enclosures that keep the sound at the speaker instead of leaking into the partitions. Four CWM7.5 speakers handle the surround effect, and six in-ceiling speakers carry the Atmos channels. Two SW-12 subwoofers sit diagonally across the room, driven by a dedicated SA1000 amplifier (now replaced by the TDC-3200W), for even pressure at every seat. The whole system is run by a Denon AVC-A110 processor.
Calibration matters as much as the gear. The side speakers are set at 90° to the listener, and the seating position was adjusted to land exactly inside the sound stage. That adjustment is done on site, once the room is ready.
Design your private cinema in Chamonix with the AiOHC private configurator
The owner defined this project upfront using our AiOHC private configurator, which lets you simulate a room's equipment and budget in a few clicks. Once the configuration is set, there are two options: we carry out the full installation at your property, or you have your own tradespeople execute it from our plans. That flexibility is especially valuable in Chamonix and Haute-Savoie, where the room is often born in the middle of a renovation already under way.
FAQ on private cinema in Chamonix
The budget depends on the size, the equipment level and the soundproofing work required. A serious dedicated room starts at a few tens of thousands of euros and scales up with the picture, sound and finish. The AiOHC private configurator gives you a costed estimate before any commitment.
Yes, it's actually the best time. Building in the soundproofing, cabling and acoustics during the works avoids having to break things open later. We supply the layout and plans for your tradespeople, then we take over for the equipment and calibration.
The soundproofing relies on a decoupled partition, built with a double layer of plasterboard with a heavy material sandwiched inside and reinforced with Fermacell board. The goal is to stop vibration spreading through the timber structure. Stretched fabric and absorbent panels then refine the listening inside.
Yes. We design and install private cinema rooms throughout Haute-Savoie and the Mont-Blanc massif, whether the project starts from an existing room or a renovation site.
A dedicated room gives full control over light and acoustics, so the result is closest to a real cinema. A living-room home cinema fits into the lounge and stays multi-purpose. The choice depends on the space available and the intended use.
