### Levels and Upgrade Costs
* **Six buildings** can be upgraded from level 1 to level 20.
* Upgrade cost depends on the building type and level.
For example:
* Office and Stadium upgrades start at 60,000 LAZY for level 2 and reach up to 2,500,000 LAZY for level 20.
* Other upgradable buildings start at 25,000 LAZY and go up to 1,000,000 LAZY at level 20.
Construction time increases with each level:
* From 24 hours for level 2.
* Up to 105 hours for level 20.
***
### Building Construction Acceleration
* You can speed up building upgrades by spending Gems, the game’s premium currency.
* Speeding up allows you to instantly complete upgrades and get advantages faster.
* The cost of instant completion is 1 Gem per building level.\
For example, accelerating level 8 costs 8 Gems, and accelerating level 20 costs 20 Gems.
***
### Building Construction Management
When construction of a building begins, the control panel changes to show:
* **Cancel construction button:** Stops the construction process. Already spent resources are not refunded.
* **Progress bar:** Shows the remaining time for construction completion.
* **Instant completion button:** Allows you to finish construction instantly by spending Gems.

**Important: Only one building can be under construction at a time.**

### Building Downgrades
* Buildings can be downgraded to optimize your club’s income and expenses.
* Downgrading is instant but non-refundable — you do not get back LAZY spent on upgrades.
