One Central Square
Office & Workplace · Cardiff, Wales
COMPLETED 2023
An office building where every room is defined by its ceiling — a lit frame over the boardroom table, timber slats over the breakout, dark slats over the café. The scheme runs a two-product base layer through all of them and then adds one distinct feature per space, so the building reads as varied to the people using it and as a very short schedule to the team maintaining it. Regents LED supplied the meeting suite, breakout floor and café.
Boardroom
Good on Camera

A modern boardroom is a broadcast studio for an hour a day, and that changes the specification. RL-PNL2663-PN carries the general layer at CRI above 90 with switchable colour temperature — camera-grade colour, and the ability to move from a 4000K working meeting to a warmer 3000K reception on a scene call rather than a rewire. 40/48/60W at 120lm/W in a 38mm slim body. RL-LIN-REC draws the continuous rectangle around the raft, which is what visually anchors the table beneath: the light figure and the furniture read as one object rather than two. RL-DL3333 takes the perimeter, with a super-deep cup because the table is a large polished veneer surface and everyone across it is looking through the reflection. RL-ST1226 lifts the raft edge off the soffit so the dropped ceiling floats rather than sitting as a bulkhead.
Breakout & Tea Point
Light Between the Slats

A slatted ceiling is unforgiving: put downlights in it and the slats cast stripes across the floor all day. RL-LIN-REC is run continuously between the timber instead, which is the only way to get even light out of a ceiling like this one. Over the counter, RL-PD9012 hangs as a cluster of thin cylinders at varied drops — Ø30 or Ø50 at 300mm, 5 to 7W each, small enough that a dozen of them read as a texture rather than a dozen light fittings. RL-ST1226 is concealed under the tea point wall units and behind the display shelf, putting light on the worktop and the magazines without adding another visible source to a room that already has plenty. RL-DL3333 covers the flat plaster areas beyond the raft.
Café
The Same Detail, Darker

The café repeats the breakout's ceiling detail in a dark finish, which is what makes two very different rooms feel like one building. RL-LIN-REC runs between the slats again — and matters more here, because a dark ceiling absorbs light rather than bouncing it, so the fittings have to deliver directly to the floor rather than relying on the surface above. Over the servery, RL-PD6008 hangs as black metal domes at 20 or 30W with a 38° beam, putting light onto the counter and the food rather than washing the menu wall behind it. RL-DL3333 fills the white ceiling across the seating, kept low enough that the counter reads as the brightest thing in the room and people know where to go.
