Sparkling Skylands: rebuild the huge building · Pokémon Pokopia

Help Tinkmaster restore the lifts and complete the multi-floor construction.

Walkthrough

The elevated ruins contain the former Celadon and Saffron areas. The main building project restores Silph Co.; locate Tinkmaster and follow its requests for concrete and lifts.
Conkeldurr’s mixer supplies concrete, while Tinkmaster provides Tinkagears for the lifts. Keep extra construction materials in storage because each floor has a separate requirement.
Assemble the 2F team with Professor Tangrowth, then prepare 3F and 4F in order. The source recommends Chef Dente on 3F and Peakychu on 4F; it does not present them as mandatory.
The three floors together require 90 Concrete and 35 Glass, in addition to their individual metals, glowing stone, paper, brick and lumber. The team grows from six to ten to fifteen Pokémon.
Once 4F is finished, go to the roof and investigate the portal and Master Ball. Mewtwo appears in the resulting scene. Befriend Porygon and complete its request separately to unlock wireless power transmitters.

Floor	Materials	Team
2F	25 Concrete, 10 Glass, 5 Pokémetal, 10 Iron Ingots	6, including Professor Tangrowth
3F	25 Concrete, 10 Glass, 10 Glowing Stone, 15 Copper Ingots	10; Chef Dente recommended
4F	40 Concrete, 15 Glass, 10 Paper, 10 Brick, 20 Lumber	15; Peakychu recommended
