Historic Courtroom Renovation: Column, Sightlines, and Secure Circulation
A 1920s courthouse courtroom is 11 m by 8 m with a 4.2 m ceiling. The judge's bench sits on a 750 mm dais against the east wall. A seven-seat jury box runs along the south wall; the witness stand is between the bench and jury box. Two counsel tables face the bench, and 36 fixed public seats are at the rear. A 400 mm square structural column stands 3.2 m from the jury box and 2.4 m from the north counsel table. The court wants to add a 2.5 m diagonal digital evidence display and a video conference camera for remote witnesses. The sheriff requires a secure route from the basement holding area to the bench and a separate public exit. The only accessible entry is at the rear of the gallery. Mock sightline checks show juror 7 cannot see the witness's face or the proposed display, and the judge's view of the north counsel table is partly blocked by the column. Renovation must preserve the historic ceiling and public gallery capacity where possible.
1. Diagnose the sightline conflicts and propose layout changes that do not assume the column can be removed.

The conflicts are geometric, not cosmetic. Juror 7 sits at the far end of the jury box; the witness stand and any display placed near the bench fall outside a comfortable sightline, especially if the display is angled only toward the center of the jury. The column sits between the judge and the north counsel table, so the judge loses eye contact and may not see documents or counsel's hands. Moving the judge's bench or raising the dais worsens accessibility and does not solve the column.
A workable scheme is to keep the column and treat it as a fixed constraint. Rotate or slightly angle the jury box so juror 7 has a direct line to the witness stand; add a second, smaller display on the south side angled toward the end jurors rather than relying on one 2.5 m diagonal screen. Move the north counsel table toward the center and slightly forward so the judge's sightline passes to the side of the column, and mark the table position on the floor. Place the main evidence display between the jury and witness but out of the counsel-to-judge line. Confirm with a scaled plan and eye-height sections, not just a plan view. If the column still blocks the judge's view of counsel, reposition the table rather than modify the historic ceiling or bench.
2. Integrate the secure holding route, public exit, remote-witness camera, and accessible entry without undoing the sightline fixes.

Security and accessibility should be solved as circulation layers. Bring the in-custody route through a locked door directly behind or beside the bench, so the defendant enters the well without crossing the public gallery or counsel area. Keep the public exit at the rear, but separate it from the accessible route by a clear path wide enough for a wheelchair and a companion. The remote-witness camera should be mounted where it captures the witness and, on a second camera, the judge and counsel-not a single wide shot that makes lip-reading impossible. Place the camera so it does not force the witness stand into the jury's sightline.
The accessible entry at the rear is acceptable only if the route to the well, jury box, and witness stand is level or ramped and does not pass through the secure holding corridor. A jury-box ramp or lift must not block the sheriff's route or the public aisle. The trade-off is that lowering the jury box to 450 mm improves access but changes historic millwork and sightlines; retaining the 750 mm bench dais is less critical than the jury and witness access. Document the sightline checks after each move, because a camera or display added late can reintroduce the same obstruction the column creates.
