Small and narrow tube houses are very popular in Vietnam urban areas . This house has the same features with only one small façade, shortage of light and dampness. The architects have come up with a solution to design more atriums to get maximum light and wind: saving electrical energy (lights, air condition...) and limiting the impact to the environment. We use locally available raw materials and do handmade which cost savings to bring a sustainable project. Therefore, bare brick, bare concrete and oak are the main materials used with the desire to create rusticity and be close to nature.
