Drawing the floor plan before the programme
The most common error is a floor plan drawn around the room rather than around the programme. A space is measured, a set is sketched in the middle of it, and only then does anyone ask how many presenters, how many cameras and how many format changes the studio must handle in a week. By that point the walls are fixed and the compromises begin.
Start with the output instead. Write down the shows or streams the studio will carry, the number of people in shot, the camera positions each one needs and the longest set change you expect. Those answers decide the usable floor, the throw distance for each lens and the clear space behind the cameras for operators and cables.
From my side as a lighting lead, this matters early. If the floor depth is decided without thinking about lamp throw and backlight angle, the lighting plan inherits a room that cannot be lit well, and no fixture choice repairs that.
- List every format the studio will carry before measuring anything
- Note the longest set change and who performs it
- Leave operator and cable clearance behind each camera
Ceiling height and the grid nobody checked
A lighting grid is only useful if the ceiling lets it work. We regularly meet rooms where the height looked generous on a drawing, then lost half a metre to ducting, sprinkler pipes and structural beams. Lamps hung below that clutter sit too low, throw steep light onto faces and cast shadows onto the backdrop.
Walk the room with a tape and a torch before committing to a design. Record the clear height at several points, not just the centre, and note anything that crosses the space. Ask the building owner what may and may not be fixed to the structure above, and what loading it carries.
Plan the grid with the rig in mind: where each fixture hangs, how much it weighs, and how someone will reach it for focusing. A grid that cannot be reached safely tends to be left untouched, and the studio ends up with whatever lighting was set on the first day.
Power, cooling and the cable routes that grow
Cable routes are usually treated as a detail to settle at installation, and that is where most of the later trouble begins. Power and signal cables run too close together, trays fill within a year, and every new device means pulling something out. Hum, interference and untidy floors are the visible results.
Separate power from signal from the start, with trays or ducts sized for more than you need today. Label both ends of every run in the drawings, so whoever comes next can trace a cable without opening a wall. Keep the routes short and keep them out of walkways.
Heat is the quieter problem. Lamps, racks and people all add to the load, and a studio that feels fine during a short test can become uncomfortable in a three-hour recording. Ask what the cooling must cope with at full use, and check that its noise stays away from the microphones.
- Keep power and signal runs apart and labelled at both ends
- Size trays for growth rather than the first day's equipment
- Work out the heat load at full use, not at a test
Treating sound and light as separate problems
Light and sound compete for the same space, and they are often planned by different people at different times. Lamps are hung where microphones need to be. Fixtures with noisy fans end up over a presenter's head. Hard, bright surfaces chosen to look good on camera make the room ring.
The remedy is to put both on one drawing early. Mark where booms and overhead microphones will travel, where lamps hang, and where acoustic treatment goes. Where they collide, it is far cheaper to move a line on paper than a fixture on the grid.
I work closely with our audio engineer on this, and the conversation is usually short when it happens early. The same conversation held after installation involves ladders, rewiring and a lot of patience from everyone on the floor.
Leaving out the people who will run it
A studio designed without the operators in the room tends to suit the drawings better than the crew. Control positions face the wrong way, the vision mixer cannot see the talkback panel, and the person managing the gallery has no line of sight to the floor manager. None of this appears on a plan until someone sits in the chair.
Ask the people who will use the studio to review the layout at the sketch stage. Have them walk through a normal show on paper: where they stand, what they reach for, who they need to see and hear. Small changes at this stage cost almost nothing.
Also decide who looks after the studio afterwards. Equipment that nobody is responsible for drifts out of focus, out of tune and out of date, and a clear owner for each system is part of the design, not an afterthought.
- Review the layout with the crew before it is fixed
- Check sightlines between gallery, floor and talkback
- Name an owner for each system once it is installed
Buying equipment before the design is settled
Equipment is the enjoyable part of a studio, which is why it gets bought first. A camera package is ordered, a mixing desk arrives, and the design is then asked to accommodate them. The result is often a room shaped by a purchase rather than by the work it is meant to do.
Hold the orders until the layout, power and cable routes are agreed. Then choose equipment that fits the plan, with some space in the racks and some spare inputs for what you will want in a year. Anything you buy early is a constraint you have taken on for free.
This is also the point where a second opinion is cheap. A short review of a plan before purchase often finds a single clash that would otherwise be discovered with the equipment already in boxes.
Most studio design problems are decided early and discovered late. They come from a plan drawn around the room instead of the programme, from a ceiling or cable route nobody measured, and from sound, light and crew being considered separately. Settle the output first, measure the real space, put every system on one drawing, involve the operators and buy equipment last. None of it is complicated, but it does ask for patience before the first fixture goes up.
