The collective 3D build
Each team builds its own module from its own plan. Assembly happens only at the end, and nothing stands unless the modules fit together.

A piece too big for one table
The finished object is cut into independent modules: a building by floor, an industrial site by zone, a city by district. Each team gets its module, a plan of a few pages and its own stock of bricks, and works without seeing what the others are doing.
The joining dimensions are printed on every plan. A module one stud too wide will not fit, and it has to be reworked in front of everyone.
The largest pieces are built on the floor rather than on tables. People crouch, move around, go and look at the module next door: the room moves instead of staying seated.
How it works
- You tell us what the piece showsYour future head office, your industrial site, your product range, the map of your locations. We start from plans, photographs or a simple sketch.
- We cut it into modulesThe number of modules follows the number of teams, and their difficulty follows the length of your slot. We send you a preview of the finished piece: you sign off before the first brick is laid.
- We set upWe arrive ahead with bricks sorted module by module, the plans and the hosting team. We need floor space or tables, and light.
- The teams buildEach group works on its module, plan in hand. A host circulates and answers questions on dimensions: alone up to sixty participants, as a pair up to a hundred.
- The assemblyThe modules come together in front of the room, in the order of the master plan. We pack up our equipment and leave the piece standing for the rest of your event.

When this is the right format
A merger
Two entities that do not know each other build modules that have to fit together. Teams are made up from both sides, and the joint is tested at the end in front of everyone.
A head-office move
The piece is the building you are moving into. Your teams build it before they set foot in it, and the model travels with them to the new lobby.
A room on its feet
Building on the floor gets the group moving: people walk between the modules instead of sitting at a table for two hours.
An object in three dimensions
The piece stands up: it sits on a reception desk or in a display case, and you can walk around it. A mosaic hangs on a wall.
What people ask
What does it cost exactly?
Our rates are provided on request, within 24 to 48 working hours.
How many people can take part?
From twenty to three hundred and fifty in a single session. The number of teams sets the number of modules: above a hundred participants the piece is cut more finely so that nobody waits for their turn to build.
Do we need floor space?
For the largest pieces, yes: allow a clear area in the middle of the room, plus sorting tables around it. For mid-sized formats, tables are enough. We confirm feasibility from your floor plan before booking.
How far ahead should we book?
Three to four weeks for a standard format. Six weeks if the piece reproduces a building or a site of yours: the design is drawn from your plans. In May, June and December, book earlier.
What happens to the piece?
It's yours. At Grundfos it stayed on display for the rest of the offsite. Most clients then install it in a lobby or a meeting room; some break it up into leaving gifts.
Do you work with event agencies?
Yes. The Grundfos build was designed and hosted with the agency Jolico Events, in Grenoble. We work as a direct subcontractor, on your schedule, with a single point of contact.
You are merging, moving, or launching a range.
