What are the legal height requirements for railings?
We get this question a lot. What is the height for Building regs for the balustrade? Or similar. In the United Kingdom this question is answered in BS6180:1999 Barriers in and about buildings:
For internal balustrades or railings that are used in a single family home on landings or other areas but these balustrades must be INTERNAL, then the height required is 0.9 meters (900mm) from where you can stand on to the top of the handrail. For stairs this is the same in this area as well.
For exterior balconies, roofs or terraced areas the required height is 1.1 meters (1100mm) from where you can stand on to the top of the handrail.
Please feel free to ask any questions.
