==Summary== 
*The Star Laboratory is a building that allows the player to upgrade their troops, much like the [[Laboratory]] in the Home Village. The Star Laboratory is unlocked at [[Builder Hall]] level 2.
**At the beginning of the tutorial, the Star Laboratory is ruined. It is automatically rebuilt after repairing the Builder Hall during the tutorial.
*Like in the Laboratory, if the Star Laboratory is upgraded while research is in progress, the research will continue as usual. However, research improvements become avaliable only after the Star Laboratory's own upgrade concludes.
*Troops are upgraded using [[Builder Elixir]]. Upgrades may improve their hitpoints, damage, their special ability, or the number of the same type of troop that is able to fit into one {{B|Army Camp}}. These vary between troops.
**All troops unlock their special abilities at level two, except the [[Night Witch]], whose ability is unlocked at level four. The abilities improve as a troop is upgraded.

==Upgrade Differences==
*Each time the Star Laboratory is upgraded (depending on what level) you can see Roman numerals (I-X) in front that corresponds to the level of the Star Laboratory.
*The Star Laboratory undergoes significant changes at levels 1, 3, 4, 5, 6, and 9. 
**At level 1, the Star Laboratory appears to be an observatory-like building with a small telescope protruding through its top tied with ropes.
**At level 2, the ladder is moved to the left side of the Star Laboratory with a ramp on the right. The rope is removed from the telescope, and its rim becomes stone.
**At level 3, the telescope is longer and a ramp replacing the stairs on the left side. The door frames are also partially gold, and the telescope's rim becomes metal.
**At level 4, the telescope is now golden along with the door frames and the ramp on the right side is replaced by a pressure gauge, similar to those on the [[Laboratory]]. The roman numerals also turn gold.
**At level 5, the telescope becomes rotatable on top of the Star Laboratory using gears. The ramp on the left side turns into metal stairs. The blue gear on the top by the telescope turns golden.
**At level 6, the telescope's aperture is larger and the type is changed with a refracted focal length, making the overall length shorter.
**At level 7, a secondary, smaller telescope is added to the right of the primary.
**At level 8, a tertiary telescope is added next to the secondary on top of the primary. The pressure gauge also turns golden on top.
**At level 9, the main telescope is reversed to normal length. The needle on the gauge also disappears. A stone also is placed behind the gear.
**At level 10, the stone bricks are replaced with gold. Gold bricks are also added to the bottom-centre part of the building.

==Trivia==
*Like the [[Clock Tower]], and [[Town Hall]]s 12, 13, and 14, it has Roman numerals corresponding to its level.
*The Star Laboratory is the [[Master Builder]]'s favorite building, as mentioned in the tutorial.
*Unlike most other Builder Base buildings, the Star Laboratory takes up a 4x4 space.
*All troops can be upgraded to level 2 without having to upgrade the Star Laboratory to match the [[Builder Hall]] level.
*The Star Laboratory has the same research icon (with a sword and a spell bottle) as the [[Laboratory]]. Ironically, the Builder Base has no spells to upgrade.
*The upgrade time and cost of each troop "smoothly" follows the time and cost to unlock it (i.e. upgrading the [[Builder Barracks]] to the corresponding level).
*Interestingly, in the Builder Base's Star Laboratory, when clicking a maxed out troop for your Star Laboratory level, the game shows you all of the levels and upgrade bonuses, as would normally happen if the troops was not maxed. However, in the Home Village's Laboratory, if you have maxed out a troop or spell for your Laboratory level, and click on it, the game tells you, "Level __ Laboratory required".
*Reflections of the ground and sky can be seen in the telescope lens of the destroyed Star Lab, and at level 9, reflections of the main telescope can be seen in an additional two small lenses.
