People more and more started thinking about the others, about people with special needs and those in wheelchairs (Convertible Stair Ramp Time and Energy Saving). They often have problems with the access to the buildings because of the luck of the ramps. This smart design of Chan Wen Jie is exceptional idea for making this much more easy.
This convertible stair ramp reduces the space for the stairs, goes under the regular ones and can be used as both- ramp or stairs. This way there will be skipped the construction element and will allow someone in a wheelchair to go in just after a simple adjustment.
