The Master Builder’s Hut served as the residence for the Master Builder in the Home Village, functioning as an additional Builder’s Hut. It became accessible once the O.T.T.O Hut (previously known as the B.O.B Control) was constructed and fully upgraded. Meeting the requirement of Town Hall 10 was necessary, indirectly linked to the upgrades of the O.T.T.O Hut.
Differing from the regular Builder’s Huts, the Master Builder’s Hut was situated on an elevated platform, accessible by a ladder and featured additional support beneath the window. However, unlike the other Builder’s Huts, it couldn’t undergo any upgrades. Consequently, it did not grant any special abilities to the Master Builder or the building while located in the main village.
In the May 2023 update, the Master Builder’s Hut was replaced by the B.O.B’s Hut, which served a similar purpose of accommodating an extra builder.
