About this block

The stair climbs in three flights around two quarter landings: treads 1 to 10 run along the bottom, 11 to 14 turn up the right-hand side, and 15 to 18 finish along the top, each one numbered on the drawing. The handrail is drawn as a rounded band following the inner edge all the way round, and two level marks, +1,70 and +2,38, sit at the ends of the first and second runs. The block holds 54 lines, 20 text entities and 6 arcs on layers DUVAR, TARAMA and YAZI.

Those levels are the useful part. Ten risers reaching +1,70 and fourteen reaching +2,38 both work out at a 17 cm rise, so the flights are consistent and you can carry the same riser on up to your own floor level. Read the footprint of about 4.5 by 4.8 units as metres and it fits an apartment or small office core. Mirror it for the opposite hand, then explode and renumber, since the numbers are plain text and will read backwards otherwise.

Questions

What riser does the stair use?

Seventeen centimetres. Ten risers reach +1,70 and fourteen reach +2,38, so both flights work to the same rise.

Can I carry it up another storey?

Yes. Copy the arrangement above itself and keep the 17 cm riser; check that the head height over the lower flight still works.
