A Capsule House (カプセルハウス) is a type of house that can be put away and carried around in a capsule. They are usually priced at half a million Zeni. The concept of the Capsule House was first introduced in Akira Toriyama's one-shot The Adventures of Tongpoo.
Notable Capsule Houses
Bulma's Capsule House
Bulma's house that she owned when going on her trip to find the Dragon Balls. She camped with Goku in Skull Valley with this house. She lost this house when she lost her capsules in a lake just before arriving near the Diablo Desert.
Bulma's Capsule House in the Emperor Pilaf Saga is Capsule #1.
Bulma's Second Capsule House
Appearances in video games
In Dragon Ball: Xenoverse, several buildings in Toki Toki City have numbers on them that indicate they are a type of Capsule House used by the Time Patrol as shops and other facilities used in their Time Patrol duties. This may explain how Toki Toki City is able to be rebuilt so quickly after Demigra's attack as any shops/facilities damaged during the attack could be replaced with spare buildings stored in capsules and/or that the building could be safely stored in capsules during emergencies such as Demigra's aforementioned attack. These Capsules where presumably provided by Future Trunks' Capsule Corporation, which is said to supply the technology, robots, Time Machines, gear, and items used by the Time Patrol.
The capsule house appears in the Live Action Korean Dragon Ball film. The design is entirely different from any shown in the manga & anime.
