The Tree Top Residence project was accomplished by Belzberg Architects studio in Los Angeles, the USA. This modern manor is constructed on the complicated landlot with rugged topography and plenty of greenery. The house`s geometry is totally compliant with natural conditions: it is prolonged and narrow and is towered upward for 2 stories. The dynamics of vertical and horizontal lines is fascinating. The core architectural element, which unites the spaces, is a sculptural staircase. It decorates the hall zone downstairs and leads towards the living room. The staircase splits the parents` and children`s bedrooms on the second floor and permits the light through to the basement level. Sliding doors contribute to good internal space insolation and unite it with marvelous nature around.
