The Operatory

A magazine about dental office design, planning and delivery in the Pacific Northwest. It follows one project from the first walk-through to the day the practice opens: how daily work becomes a floor plan, how the interior treats patients and staff, and how construction, equipment and budget are delivered.

Edition of 16/09/2026. Entries revised between 11/09/2025 and 07/09/2026. Nothing on this site is sold and no practice, clinic or supplier is recommended.

Wide documentary view of a dental office under construction from the corridor doorway, pale cabinetry along one wall, bare ceiling services overhead, grey floor protection and soft daylight across the working area.

Plate 3:2 · the whole room seen from the door

A dental office is planned in one direction only: the daily work first, the walls after. Five numbers carry most of that work, and every one of them is a clearance rather than a surface.

A floor plan is a set of clearances before it is a set of rooms. The chair needs room to recline, the assistant needs a side to work from, the tray needs a route to sterilisation, and a wheelchair needs to reach the same chair without turning a corner nobody drew.

The table below opens the edition. It lists what each room of a practice holds, the clearance that decides the room, the adjacency the work demands, and the share of floor area the room takes from a fixed lease.

01The ranking of rooms

12 rooms, one lease

How the areas are counted, and what the table does not measure

  • Areas are given as a range for a general practice of four to six chairs, measured inside the finished walls.
  • The share column is read against the total leasable area, not against the sum of the rows.
  • Where a code fixes a figure, the code is named in the entry; where a range comes from published planning sheets, the sheet is named.
  • A corridor is counted as a share of the plan, because it is what remains after the rooms are placed.

The table does not measure construction cost, staffing or equipment budget, and no single figure in it survives a change in the number of chairs. It is an ordering of constraints, not a plan.

06The four sections

20 entries across 4 sections

The edition is read in four sections, and it is worth starting with the parties before the plans. Who does what sets out what a dental office design practice does once the scope is written down, and how the work divides between the people who treat patients and the dental team and floor plan decisions they own. Reading the evidence takes the opposite view: what a dental office client list records and what it leaves out, how far a design practice's references can be checked before a first call, and how a dentist can read a design practice's completed projects without being misled by the finishes. Stage by stage and The interior carry the project itself.
