Assembly Hall at Church House Westminster

Assembly Hall is 22.8 x 22.8 m (75 x 75 ft), 520 m² (5,595 sq ft), with a 9.7 m (32 ft) ceiling.

Plan view

Shape approximate: the venue publishes area only, so this room is drawn as a square of equal area.

LED wall that fits

Under a 9.7 m ceiling with 1.5 m trim and 0.3 m clearance you get 15 rows of 500 mm tile flown. Along the 22.8 m wall a Absen PL2.5 Plus V2 wall runs 36 x 15 (7200 x 3000 px, 4,212 kg, 86.4 kW).

Wall sizing assumes 1.5 m trim to the bottom edge, 0.3 m clearance under the ceiling, and a wall no wider than 80% of the longest wall. Weight and power are tile totals from the panel spec sheet; add processing, rigging, and cable.

Seating estimate

After a 12 x 7 m stage, Assembly Hall holds about 968 theater seats, 396 banquet seats at rounds of 10, or 272 classroom seats. Back row in theater is roughly 15.8 m from the downstage edge; the previz checks whether the bottom of the wall clears the heads in front.
