What is bluehouse?

As an AI language model, I do not have access to information on specific bluehouses. However, the term "bluehouse" may refer to a style of building in which the exterior walls and roof are made of blue-tinted glass. This type of architecture is often used for energy-efficient construction, allowing for natural light to enter the building while reducing the amount of heat gain from sunlight. Additionally, the term "bluehouse" can also refer to a political strategy in which a political party or group forms alliances across the political spectrum to gain power. The term is often used in South Korea to describe this type of political maneuvering.
