Carving a wardrobe's stiles as deeply as these are carved runs directly against the one thing a stile has to do, which is hold the hinges.
The stiles between doors are where every hinge screw goes. They carry the weight of the doors, and they carry it in shear on a few screws biting into timber. Cut a deep pilaster into that member and you have removed material from precisely the place that was doing the work - which is why on cheaper furniture heavily carved stiles are almost always either fake, applied over a plain stile, or accompanied by doors that sag within a couple of years.
Our master Indian artisans carve the pilaster from the solid stile, and make it safe by deciding where the material stays. A full-width band of solid timber is left along the hinge face of every stile, behind the carving, running the whole height. The design of the pilaster is then arranged so that its deepest cuts - the hollows between the acanthus leaves - fall on the show face and towards the outer edge, never into that band.
The result is a stile that looks like it has been carved through and is, where it matters, as solid as a plain one.
