This stair­case in an af­flu­ent house in Kolkata is made with ter­ra­cotta tiles, gyp­sum and gran­ite, and is built with­out shut­ter­ing. It fol­lows the Cata­lan method of vault­ing, in which the tiles are held on their thin edge by the in­stant hard­en­ing of gyp­sum (plas­ter of Paris). This cre­ates a thin shell that gives sup­port to sub­se­quent tile lay­ers, laid ei­ther in gyp­sum or with slow-hard­en­ing binders like lime or ce­ment, which are cheaper and more wa­ter-re­sis­tant. These can be used in con­tem­po­rary projects, and even in com­mer­cial projects
