Stair drawing – check list.
The stages that are required to achieve the staircase and handrail to be designed without constantly redrawing the stairs are listed below, this is a quick guide with a brief explanation of the different stages.
1. Determine the layout.
This may to an extent be dictated by the floor plans and space that you have to work with.
2. Determine the space.
This will include length, width and height that each flight will be restrained too.
3. Determine the number of risers.
The rise is a fixed dimension from finished floor level to finished floor level, form this you know you will need one less going or tread as the landing is in effect a going.
4. Draw the proposed plan view.
The proposed plan view can be drawn using the handrail centre line as the edge of the stairs.
5. Draw the stretch-outs.
The stretch out will confirm the handrail flow. This will let you know if you need to tweek the plans.
6. Determin the handrail support.
Dependant on the handrail support whether it be glass, metal balusters or timber spindles. The stringer face will be determined by this.
7. Determin the handrail centre line offset.
Dependant on the handrail support the stringer face will either move into or out of the stairwell space.
8. Adjust the plan stringer faces to suit the handrail centre line offset.
Once you have your centre line offset you can draw the stringer faces and nosings etc.
9. Confirm spindle spacing.
Once you have drawn the stairs check that the spindles will fit onto the visible tread surface once the nosings have been allowed for.
