Half landing design

[Lincolnshire Ian]

Hi folks

Thanks for your previous help with designing our staircase. 

Our stairs have a half landing. I think from a building control perspective this is classed as a structural element. 

Does anyone have any tips/designs they could share to help us build a solid half landing? 

Thanks

The half landing is basically another floor to the house.  You use joists sized and spaced to support that floor in exactly the same way as any other floor.  Usually because a half landing is small, and the span is small you don't need very big joists.

 

Think of it as an extra small piece of floor part way between ground floor and first floor, with two small staircases one from the ground floor to the half landing and one from the half landing to the first floor.  It all becomes simple then.

 

In my case because we were not having fancy treads, the stairs were being carpeted, the half landing did not need to be built by the stair company.  They just built the 2 flights of stairs, and I built the half landing to join them.
