An Odyssey install runs on two to five separate 13U processing racks, none of which sit inside the console you actually touch.
That one design choice quietly reorganizes the room. The surface in front of you holds controls, displays, and faders. Every preamp, every EQ, and every compressor lives somewhere else, wired back to the desk. Where somewhere else ends up stops being a furniture decision and becomes an architectural one.
Most buyers plan the console carefully and plan the building around it late. Then the cooling quote lands.
Studios and booths are normally specified at NR20 or lower, and the racks do not reach that. So a rack tucked into the corner of a live room is a bad plan, while a rack a few feet from the console is entirely reasonable. If your building has no separate machine room, that single distinction settles your floor plan for you.
SSL leaves the choice open, offering remote, floor-mounted, and rack-mounted placement, and that flexibility is where rooms get into trouble. Given a free hand, people put the racks wherever there happens to be room. Available space is not the real constraint. Noise, heat, and cable length are, and only one of those three is obvious when you walk through an empty building.
Fan noise also moves. Active cooling responds to load, which means a rack that measures beautifully at nine in the morning can be a different animal after four hours of a busy session in August. Judge it warm, not cold.
The awkward part is that studio cooling cannot simply be made bigger. Small rooms with a heat gain of only two or three kilowatts are already hard to serve without oversizing the equipment, and oversized equipment moves more air, which makes more noise. Supply velocity in a studio typically sits between one and two meters per second, far slower than a normal office system, precisely to keep it inaudible.
Metal ductwork gives almost no useful attenuation on its own, so hitting NR25 means attenuators in the ducts and often fabric-lined runs. None of that is expensive individually. All of it together is why the heat load those racks add to the room deserves a conversation with a mechanical engineer before the frame is ordered, not after.
Long mains runs, and long audio runs also dislike each other. Standard practice is to feed audio equipment from its own supply, separate from air conditioning and everything else that switches on and off during the day, and to keep audio cable away from mains cable, crossing at right angles where a crossing cannot be avoided. Scale that thinking to the largest Odyssey configuration SSL offers, and you are planning a machine room, not a cupboard.
One practical wrinkle sits underneath all of this. SSL does not publish the console's weight, dimensions, or power consumption on its website and instead directs buyers to installation documentation issued by its specialists. Those numbers exist, and your structural engineer and your HVAC contractor both need them well before the room design is locked, because a frame that arrives before the building is ready is an expensive piece of storage.

The racks are quiet enough for a control room, and no quieter
SSL rates the ActiveAnalogue racks below NR25 with active cooling running. That number is not arbitrary. NR25 is the standard design target for a control room, so the racks are built to share a space with the engineer without ruining it.Studios and booths are normally specified at NR20 or lower, and the racks do not reach that.

Cooling is the line item that gets underestimated
Air conditioning designers size studio systems from sensible heat gain, calculated from air volume and the difference between supply and room temperature, usually around ten to twelve degrees Celsius on a mixed flow system. Add several racks of always-on analog electronics, and that figure climbs fast.The awkward part is that studio cooling cannot simply be made bigger. Small rooms with a heat gain of only two or three kilowatts are already hard to serve without oversizing the equipment, and oversized equipment moves more air, which makes more noise.

Your patchbay moves to wherever the racks end up
Because the analog circuitry lives in the racks, your microphone lines, inserts, and tie lines terminate there too. The desk is no longer the center of your copper. That changes where the patchbay goes, how long your runs are, and which wall gets torn open.Long mains runs, and long audio runs also dislike each other.
