The weather in the North Europe is not very stable. Usually the houses should be heated more than half year in a row. For example, the weather in Oslo, Norway is cold and unpredictable so Rintal Eggertsson Architects created great 19m² prefab house which is easy to heat and has stylish appeal. The project is called Boxhome and is more ecological and economical friendly than common house construction. Even though such house isn’t an option for main family house, it’s great as summer house or cottage. The prefab house has four rooms covering the basic living functions: kitchen with dining, bathroom, living room and bedroom. With such minimalist, modern look the house could become very popular in Scandinavia countries.
