The interior design of a small barbershop, inside a narrow room approximately 3m by 5m , with two barber chairs with red upholstery, two mirrors, a hair washbasin in the background by the side of a black spiral staircase. Use mint green, gold and black as main colors. Make the floor out of black and white speckled granite. Place lots of plants, hanging from the ceiling (3.5m ceiling height) or in pots hanging from the wall. Use spotlights and industrial light pendants. Use a retro modernist style like "The Incredibles" Pixar movie. Make everything looks shiny and clean.  --ar 9:16
