L Shaped treads present an excellent chance to design a staircase that complies with the Staircase Building Regulations in the UK, specifically adhering to the 100mm rule, without the need for glass or metal riser bars or solid wooden risers. This innovative approach not only retains the visually appealing open staircase look, but it also introduces the advantage of an L-shaped tread configuration that creates a cost-effective and lightweight alternative with the appearance of sleeper treads. By incorporating these features, one can achieve an aesthetically pleasing staircase while ensuring compliance and optimizing efficiency, all while minimizing expenses and weight.
