Interior Space and Exhibition Design Life with Mountain Residential House by Lo Fang Ming On the premise of not changing the building structure, the designer introduces the concept of visual compensation. For the height layers of the three consecutive stages, the front and rear walls are precisely connected with the clear vertical lines of the iron pieces and grilles to greatly enlarge the space dimensions. There are also several pillars in the secondary bedroom on the second floor. According to the functions and situations in life, the designer rearranges the space for more possibilities in space usage.
