To plan lighting for an office that switches between desk, meeting, and counter work, start with what never moves: windows, doors, existing lights, and fixed work surfaces. Next, record the surface and viewing direction for each work mode. Only then add the furniture arrangements you actually use.
Planning this way helps you map fixed conditions alongside different furniture setups rather than designing solely around wherever the desk sits today. Desk work with screens and paper has clear published guidance from OSHA's workstation recommendations. Meeting and counter use need careful notes on surfaces and sightlines that you carry into fixture comparison.
Start With a Map of Fixed Surfaces and Viewing Directions
Your first result is a simple room sketch, drawn before any fixture is on the table. It records what stays put and which way people look while they work.
- Sketch the room outline. Rough scale is fine. Write the length and width in feet along the walls.
- Mark windows, doors, and existing lights. Include ceiling fixtures, wall lights, and any skylights.
- Label every surface fixed or movable. A built-in counter or wall-mounted desk is fixed. Rolling tables and freestanding desks are movable.
- Draw a viewing arrow for each work mode. Show which way a person faces at the desk, around the meeting surface, and at the counter. Give the counter two arrows: one for staff and one for visitors.
When you finish, you should have one base map with fixed features plus arrows for desk, meeting, and counter use. Keep it as observations only. Fixture ideas come later, after you compare tasks and furniture moves. Graph paper works, or you can start the sketch in our online layout tool.
Compare Desk, Meeting, and Counter Work
Each work mode puts a different surface in front of people and points their eyes a different way. Record those details separately for each mode.
| Work mode | What to record | How to use it |
|---|---|---|
| Desk | Monitor direction, nearby windows and lights, paper-work spot | Apply workstation glare checks |
| Meeting | Shared surface location, direction each seat faces | Keep for a later design review |
| Counter | Counter surface, staff side, visitor side, anything hanging above | Compare with a reception example |
The desk row has the most specific guidance. OSHA's computer workstation guidance advises placing the screen at right angles to windows and light sources and aiming task lighting so it does not reflect on the screen. It also calls for supplemental task lighting for writing and reading while limiting brightness around monitors. So if one desk handles both screen work and paperwork, your map needs both the monitor direction and the paper spot.
That OSHA advice is written for computer workstations, so don't stretch it to the meeting table. For meetings, the useful record is where the shared surface sits and which way each seat faces. Those notes give a designer or a fixture comparison something concrete to work from.
Counters have two sides, so note where staff work and where visitors stand. One reference point comes from the VA lighting design manual. For public-area reception desks, it says to consider vertical illumination at the desk or the wall behind it, and to make sure decorative pendants don't block the receptionist's line of sight. Use that as a reception example to compare against, not as a rule for every small-office counter.
Glare can come from several directions. An Oregon DHS/OHA office lighting guide names fixtures, windows, and skylights as glare sources. It lists moving the light source, moving the work activity, adjusting lighting levels, or adding filters as possible controls. Mark those sources near each surface on your map so the options stay visible later.
Overlay Furniture Changes Before Choosing Fixed or Movable Light
Treat the base map as fixed and draw each furniture arrangement on top of it. This keeps the plan from being anchored to the desk's current location.
GSA's lighting guidance separates general lighting, which serves an area, from task lighting, which is directed at a specific surface or area. That split gives your overlay two clear questions. What does the whole room need in every arrangement? What does one surface need only in one setup?
- Copy the base map once per arrangement you use. Name each copy, such as "desk day" or "meeting setup."
- Move the furniture on each copy. Redraw the viewing arrows to match.
- Circle anything that changed. Flag surfaces whose position or facing direction differs between copies.
- Sort each circled surface. Write "area-wide" or "this surface only" next to it, and note which marked glare sources now sit beside or behind it.
- List what you can't settle on paper. These become open questions for fixture comparison or design help.
The result is three short lists: what stays fixed, what moves, and which lighting questions are still open. The overlay won't decide whether a ceiling layout or movable task lights will serve every setup. It shows you exactly where that decision matters.
Confirm Room and Fixture Inputs Before Selection
Before comparing fixtures, gather two groups of facts: what your room is, and what each candidate is documented to do. Pull the room facts straight from your map and overlay, not from memory of today's layout.
- Room size: length, width, and ceiling height in feet
- Fixed features: windows, doors, skylights, and existing light locations
- Work surfaces by arrangement: position and facing direction for desk, meeting, and counter use
- Open questions: the list from your overlay
- Candidate light distribution: how the fixture spreads light, from its own current documentation
- Candidate mounting: how and where it mounts, compared with your ceiling and surface locations
- Candidate output: the documented light output for the exact model or configuration
- Candidate controls: documented dimming or switching options
A blank room input means the plan has a gap. Our guide to missing project inputs shows which missing measurements, task, and control details can block reliable lighting design. On the fixture side, our photometric data guide explains how to read IES files and related reports before approving a layout. When you compare ceiling options such as LED panel lights, hold each one against your mapped surfaces and open questions.
FAQs
What if one desk is used for both screen work and paperwork?
Map both tasks at that desk. Draw the monitor direction and mark where papers sit. OSHA's workstation advice covers this mix: keep windows and light sources at right angles to the screen and add task lighting for reading and writing that does not reflect on the screen.
How many furniture arrangements should I map?
Map each arrangement your office actually uses on a regular basis, such as a normal workday layout and a meeting layout. A one-off setup you rarely use can go on the open-questions list instead of getting its own copy. That keeps the overlay focused on the layouts your lighting has to serve.
Should I map the counter from the staff side or the visitor side?
Map both. Staff and visitors often look at the same surface from opposite directions, so give each side its own arrow. Also note anything hanging above the counter that sits in either person's line of sight.
When does it make sense to get outside help with the design?
Get help when your overlay leaves open questions you can't settle on paper, like whether one ceiling layout can serve every arrangement. Our article on requesting a free lighting simulation explains the building information to send. Your room map and arrangement copies cover most of it. Leave any wiring or circuit changes to a licensed electrician.
