Staircase railings, are often very limited by the building code, yet with a lot of measuring you can incorporate the design requirements of the code and get something different.

 

 

Many Junction Houses present a tough challenge when renovating, if one of the criteria is to create an open environment. The removal of interior walls, bumping out exterior walls all can serve this idea. But those actions can be expensive and may create smaller rooms in the reaction to enlarging others.

A design fix to add viewing space is to design about the vertical members of the stair railing to of a thin high strength material. Above is a design drawing and completed build of such a design.

Below the handrail section of the code.

Building section, Height of Guards

(2) Openings through any guard that is required by Article 9.8.8.1. and that is installed in a building of industrial occupancy shall be of a size that will prevent the passage of a spherical object having a diameter of 200 mm, unless it can be shown that the location and size of openings that exceed this limit do not represent a hazard.

(1) Guards required by Article 9.8.8.1., except those in industrial occupancies and where it can be shown that the location and size of openings do not represent a hazard, shall be designed so that no member, attachment or opening located between 140 mm and 900 mm above the floor or walking surface protected by the guard will facilitate climbing.
