Located on an area of 48m2, the house belongs to Professor T. and his wife who are over 80 years old, now they’re living with their posterity. The old man, who has been reading and writing hard has a large number of books, that’s why the house named Lib - Library. Due to his old age, it's necessary to minimize circulation space for both workplace and living space. As loving plants and trees, Mr. T wants to bring not only all the books but also the plants he loves to the new house. So, from those demands, Lib house comes out as an answer for all.
