The Tools We Use to Draw a Studio Floor Plan

A studio that looks right can still sound unusable. The materials we reach for most are dense mineral wool panels behind fabric, heavier diffusers at the rear of the space, and floor treatments that stop footsteps and trolley wheels travelling into microphones. Each does a different job, so we avoid covering every surface in the same foam and hoping for the best.

Placement matters more than quantity. Absorption belongs at the first reflection points beside and behind the presenter, where sound bounces straight back into the microphone. Bass trapping goes into corners, where low frequencies gather. A flat, bare back wall is the usual culprit when a small streaming room sounds hollow.

Callum Reid, our Senior Sound Engineer, tests a room with a simple clap and a recorded sweep before we commit to a treatment plan. We would rather adjust two panels after listening than discover a problem once the set is built and painted.

The least glamorous document we produce is also the one crews thank us for: the cable schedule. It is a table listing every run in the studio, with a label, the two ends it connects, the signal type, the length and the route it takes through trunking or under floor. Without it, a fault becomes an afternoon of pulling things out to see where they lead.

We separate power, audio, video and data into their own routes wherever the room allows it, keeping mains cabling away from microphone lines to avoid hum. Where they must cross, they cross at right angles. Spare conduit is left empty on purpose, because every studio grows an extra camera or an extra screen within a couple of years.

Labels are printed, not handwritten, and the schedule is handed over as a copy for the engineer and a copy kept in the control room. A tidy patch bay is a small thing, but it decides how calm a live day feels.

I join the layout early because lighting needs to be designed into the room, not squeezed in afterwards. The tools I rely on are a section drawing showing ceiling height, a rigging plan marking where trusses or bars can safely hang, and a lamp schedule that lists each fixture, its position and its purpose. Low ceilings change everything, and they are far easier to deal with at drawing stage.

We check the throw distance from each lamp to the talent, because that decides which fixtures suit the space. A key light that sits too close creates harsh shadows and heat; too far and it loses control. Cable lengths for the rig are added to the same schedule used for the rest of the studio, so one document covers everything.

Power load is the other early check. Adding up the draw of the fixtures against the available supply stops a tripped breaker during the first test. It is a dull calculation that has saved more than one opening day.

For larger studios we build a simple mock-up before ordering anything permanent. That can be as modest as tape on the floor marking the desk and camera marks, a few chairs standing in for guests, and a camera on a stand to check the framing. It takes an hour and has changed a design more often than any drawing review.

Crews walk the space as they would on air. Presenters find out whether their mark feels natural, the floor manager sees whether they can reach each camera quickly, and the sound engineer hears the room with real voices rather than a test tone. Small adjustments made at this stage, such as shifting a desk by half a metre, cost almost nothing.

Autumn is a good moment for this work. Many broadcast teams use the quieter weeks before the winter schedule to test and settle their layouts. We note every change on the drawing so that the final plan reflects what was actually tried, not only what was first imagined.
