THE BUILDING WEEKBRUSSELS
6days
6projects
A complete idea-to-project cycle every day.
22 HOURSOVERVIEW
One idea-to-product cycle, every single day
Every session starts with a new idea. You choose a problem, define a version you can finish, build it with AI, test it, and show what you made. Then you do the whole cycle again the next day. The repetition makes the tools feel familiar so your ideas can grow more ambitious.
THE SIX DAYS
A new project each day
Join us in person in Brussels from Monday 16 to Saturday 21 November 2026. Monday to Friday, we meet from 18:00 to 21:00. On Saturday, you get seven hours. Every day contains the complete cycle: idea, scope, build, test, and show. Bring your laptop; food and drinks are served.
18:00–21:00
PROJECT 2 · TUESDAY 17 NOVEMBER
Move faster
Start a new project. Use what you learned on Monday to get further in the same three hours.
PROJECT 3 · WEDNESDAY 18 NOVEMBER
Raise the bar
Choose a more ambitious idea and take it through the full build cycle.
PROJECT 4 · THURSDAY 19 NOVEMBER
Stretch your range
Build a fourth project with a new challenge, integration, or kind of user.
PROJECT 5 · FRIDAY 20 NOVEMBER
Trust your process
Take a fifth idea from blank page to a working result with growing independence.
PROJECT 6 · SATURDAY 21 NOVEMBER
Go beyond what you expected
Use a full day for your sixth and boldest project. Build, test, and show it.
22 in-person hours · Brussels local time
PROJECT IDEAS
What could you build?
Bring your own ideas or start from a prompt in the room. These are examples, not a fixed curriculum.
A tool for your work
Replace a repetitive task with a useful workflow.
A small business app
Prototype a booking flow, customer portal, or internal tool.
An AI-powered experience
Make a research assistant, learning tool, or content workflow.
Your own long-held idea
Put a working version in front of someone and see what happens.
SKILLS AND OUTCOMES
