Lobby Impact Without Blocking Reception
A hotel asks for a permanent-style arrangement for a 1.1 m-diameter round table in its lobby. The ceiling is 2.6 m; the reception desk is 4 m behind the table, and guests approach from a corridor on the left. The client wants "dramatic, tall impact" but also an unobstructed sightline to reception. Available materials: 1.5 m curly willow, white hydrangea, burgundy dahlias, silver-gray eucalyptus, and a 30 cm cylindrical vase. Budget allows either two focal masses or one large mass, not both. The lobby has dark walnut paneling and warm downlights that graze the tabletop. The designer must choose a form and proportion that reads as dramatic without becoming a barrier.
1. Recommend a form and proportional scheme, and justify it against the table, ceiling, and sightline constraints.

Use an asymmetrical vertical form with a low focal mass and an open mid-section. Total height should be about 1.5–1.7 m: high enough to read from the corridor, but not so high that the 2.6 m ceiling and grazing downlights flatten the top. With a 30 cm vase, the willow extends roughly 1.2 m above the rim, close to a 2:1 stem-to-container proportion but deliberately airy. Keep the dense mass between 30 and 60 cm above the table, below the standing guest sightline to reception. Place the willow lines off-center toward the corridor so the approach side is dynamic while the reception side stays visually light. Put white hydrangea at the lit edge of the low mass, recess burgundy dahlias, and use silver eucalyptus to separate dark flowers from dark paneling. Drama comes from line, silhouette, and reflected light, not from a solid wall of flowers.
2. The client rejects the first sketch as "too sparse" and asks to fill the negative space with hydrangea. Explain the design consequence and propose an alternative that preserves impact.

Filling the open mid-section converts a line-mass composition into a screen. The binding constraint is the reception sightline: hydrangea placed between roughly 70 and 120 cm would block the desk and flatten the willow line. Explain that in this lobby, impact must come from height, silhouette, and light-catching surfaces rather than density at eye level. Offer a compromise: add a second, tighter low mass on the opposite side of the table for visual weight; increase hydrangea only below about 55 cm; and use translucent or reflective material in the gap-sprayed willow, bear grass loops, or glass votives. If the client insists on full mass, propose a lower, wider arrangement no taller than 90 cm, or relocate the table. Do not silently fill the gap and then discover the sightline problem at installation.
3. Evaluate whether the dark paneling and warm downlights favor burgundy dahlias or white hydrangea as the dominant focal color, and state one risk.

Warm downlights, roughly 2700 K, push reds and yellows forward and mute blues and greens. Against dark walnut, burgundy dahlias will lose value contrast unless separated by silver eucalyptus; they may read as a dark hole rather than a focal point. White hydrangea has the highest luminance and will pop, but under grazing warm light it can glare and make the burgundy look muddy. A safer hierarchy is white hydrangea as a smaller accent at the lit edge, burgundy as the mid-value mass, and silver eucalyptus as the separator. This keeps drama without relying on white as the dominant. The risk is that white hydrangea is heat- and ethylene-sensitive and may brown at the tabletop under the warm downlight; condition it well and keep it out of the hottest light pool.
