Balustrades & Building Regulations PDF Print E-mail

Staircase with balustradesA reader recently sent in the following question regarding a staircase. What is the building regulation regarding the installation of balustrades - minimum height, maximum spacing between horizontal crosses, etc.?

Les Abbott, Architect of L. A. Design Studio responded as follows:

The National Building Regulations require that any staircase in a domestic
application of more than three risers must have protection on each side provided
by either a wall, secure screen, railing or balustrade.  If such a staircase
is more than 1.1 m wide then a balustrade or handrail must be fixed to both

The balustrade must be a minimum of 1 m high, measured vertically from
the outer edge of the tread. The openings in such a balustrade must be such
that it will not allow the passage of a 100 mm diameter ball through it at
any point.

Balustrades with only a top rail and a mid rail are not permitted in any
residential application.
