Modern floating stairways and glass bridge walkways add a dramatic feeling of weightlessness to a home, while connecting the different floors and levels. Stairways lead to bedrooms and primary living suites on top floors, or down to basement level home gyms, theaters, wine rooms, and libraries. Atriums have a floating feeling when stairways and walkways cross through them, and walkways can lead to attached guest houses or meander through the grounds. Try unique stairs above reflecting pools or Zen gardens.
