This incredible staircase project by Ars Technica makes good use of the empty space that is available under each step. The piece of architecture is certainly a great way to welcome guests into your house. What is really special about this staircase project is the eclectic use of plants that appear under the steps.
For those looking to re-enact this project, it's really dependent on the type of plants being used and what the atmosphere is like in the location where it is being constructed. Creating this staircase in temperate regions may make it difficult to maintain, especially since it is extremely difficult for plants to survive during the winter months.
