The master is a professor of the life Science department.In order to echo the male master's occupation,we designed a revolving staircase with DNA.Male and female owners want to have coexistence,occasionally and have their own independent living space.The designer designed the linear design for them.They can enjoy the sweet time together and enjoy being alone.Just like the concept of DNA-the main axis of the vertical axis is in independent of the symbol of the male and female masters.It is connecting lines in life.
