At Bay Tree Design, we're always working to use natural materials in children's play spaces. Who doesn't dream of a treehouse that really makes you feel like you are in a tree?
In our quest to design this type of experience we've come across a material that is relatively new to the scene in North America, black locust lumber.
Meg Calkins recently reviewed black locust (Robinia pseudoacacia) in the Landscape Architecture Magazine's April 2017 issue. Based on her research black locust is a truly renewable product with a 50-year life expectancy and a 25-40 year growth time. This durability is exceptionally useful in play structures, weathering the elements without being treated with potentially harmful chemicals.
Recently we've begun to experiment with it in our projects. While it is commonly used for play structures in Europe it is a new material here. We can't wait to see how these play structures turn out.
