Lamm: seats that vanish under the floor — the engineering of transformable halls
The most valuable square metres in a building are the ones that do two jobs. Lamm has engineered that trick since 1959: rolling floors where entire rows of seats rotate and disappear under the walking surface, telescopic tribunes that fold against a wall, rails that slide rows beneath the stage — one hall, many lives. The maker from Parma produces and installs worldwide: conference and university seating with a Compasso d'Oro pedigree (CLACK, 1989), references from HSBC UK's Birmingham headquarters to Brunel University, and its own acoustic division, Caruso Acoustic, to make the transformation sound as good as it looks.
La Mercanti brings Lamm to UK lecture theatres and civic halls — engineering included, installation by the maker.
FAQ
How does a rolling floor actually work?
The seats rotate and retract below the walking surface: automated mechanics turn an auditorium into a flat floor in minutes — no storage rooms, no manual stacking, no lost seats.
What does maker-installation add on a UK project?
Single accountability: Lamm produces and installs worldwide, from layout and feasibility to commissioning — moving parts and warranties stay in one pair of hands.
How to double the use of one hall
Five decisions that make a single room earn twice.
List every intended use
Lecture, banquet, exam, concert: the mix picks the system.
Choose the retraction logic
Rolling floor, telescopic or rail — geometry decides.
Automate the changeover
Minutes by motor beat hours by hand, every week.
Keep acoustics in both modes
The hall must sound right full and empty, flat and raked.
Contract maintenance early
Moving systems live on scheduled service.
