The Kancha House, apart from its ability to generate food, can also act as a Wall due to its large size. It takes a lot of foundation space, and thus must be built closely to prepare a defensive wall to block enemy units attempting to raid or attack the base. The Kancha House has a built limit of 12 and provides 16 population; hence, they can only support a maximum population of 156 (166, if the starting Town Center population is included). The player has to build additional Town Centers or Kallankas to reach 200 population.
The food trickle can be further increased upon sending the "Chincha Brewing" Home City Card, which grants +0.3food every second.
Originally, Kancha Houses take 20 seconds to build. With update 3552, Kancha Houses take 15 seconds to build.

Along with Kallanka architecture, Kancha architecture was widely used throughout the Inca Empire. Kanchas were groups of primarily residential, rectangular spaces generally comprising a single room, one story high, and a shared patio space. Each Kancha grouping was surrounded by an enclosure wall of stone. Some were gabled, some not, but all tended to cover their stone bases with thatched roofing, which was pitched to control the flow of rainwater. These complexes housed large numbers of people in easily defensible locations, and their organized nature lent themselves to convenient civil administration.
