Themed workshops
The building serves one precise subject: a historical period, a planet, a neighbourhood, a waste-sorting scheme. The session runs ninety minutes to two hours and follows what the class is already working on.

The theme sets the brief
History, the solar system, architecture, the sustainable city, waste sorting: the subject defines what the children build and the constraints they have to respect. A medieval house has no glazed windows; a space station has no roof; a street with its recycling points is not laid out at random.
The session alternates short stretches: the host sets the subject and the constraints, the children build, everyone looks at what has been made, one more constraint is added. Ninety minutes allows three such sequences, two hours allows four.
The theme is agreed beforehand with the teacher or the coordinator, based on what is already on the syllabus. What was built and named during the session stays available to the class afterwards.
How it works
- You tell us what the class is working onThe year group, the current topic and what you want the children to take away. A theme outside our usual subjects can be prepared too: we hold 118,000 part references in stock.
- We set the subject and the constraintsWe turn the theme into building briefs suited to the age of the group, and prepare the matching stock.
- The sessionNinety minutes to two hours, in short sequences. One host supervises around thirty children; beyond that we come as a team. Your own staff stay present as regulations require, without having to run the session.
- A cycle, if you want to go furtherThe subject can be spread across several sessions in the year. We regularly work at that rhythm with after-school coordinators.
- What stays behindIf the session leads to a mosaic or a collaborative model, it stays with you. On a standard themed workshop, the bricks leave with us.

When this is the right format
A syllabus chapter to anchor
The Middle Ages, volumes, the solar system, the waste cycle. Pupils handle the subject before they revise it from a worksheet.
An after-school slot
Ninety minutes fits an evening or Wednesday slot, set-up and take-down included, without eating into class time.
Several sites in one week
Our rates are provided on request, within 24 to 48 working hours.
A public scheme to explain
Grand Belfort commissioned two waste-sorting models, now used as outreach material in the area's schools.
What people ask
What does it cost exactly?
Our rates are provided on request, within 24 to 48 working hours. A discount applies to multi-site tours.
Who funds this kind of session?
The school fund, the parents' association, the local council budget or the holiday centre's own budget. We provide a formal quote for your paperwork, with our company registration number and our professional public liability certificate.
Can we pick a theme that isn't on your list?
Yes. Tell us the subject and the year group: we translate it into building briefs and prepare the stock. Our 118,000 part references cover most of what is asked for.
From what age?
From five, with a simplified subject and a shorter session. The format holds up to secondary level by tightening the building constraints.
How many children per session?
One host for around thirty children, and more staff beyond that. Our rates are provided on request, within 24 to 48 working hours.
What do you need on site?
Tables, chairs and a well-lit room. We bring everything else, including protective covers.
Do you run after-school sessions?
Yes, and the short ninety-minute format is designed for it. Multi-session cycles are planned with after-school coordinators.
You have a theme and a year group.
