There is something especially satisfying about adding a building to your city that feels both beautiful and practical — and that is exactly what the new Stationery megastore brings.
The Stationery megastore combines visual charm with real usefulness. It stands out on its own, yet blends wonderfully into the city around it. It is decorative, practical, and rewarding all at once — a lovely upgrade for players who care about both aesthetics and efficiency.

How to upgrade
You can upgrade buildings to a megabuilding in the Department of Architecture (Megabuildings tab).
We would also like to remind you that all megabuildings can now be upgraded to level 13.
To do that, you will need building upgrade plans from the Countryside and upgrade plans: Islands from the Bathyscaphe.
Here are the core upgrade rules:
- Have one non-upgraded building of the required type in storage.
- Use building upgrade plast for upgrades up to level 6.
- Use the new item (Upgrade plan: Islands) for upgrades beyond level 6.
- The third item may vary by building.
More information on megabuildings here.
