Peak-load storage
Sizing storage for the largest realistic gathering a home hosts — not just its daily residents — and housing that peak kit at the periphery so it doesn't crowd everyday life. The distinctly Indian response to the joint-family / festival reality that imported plans never make.

A nuclear flat still keeps vessels, bedding and folding chairs for twenty at Diwali. Size for the gathering, store at the periphery (loft, high band, deep under-bed): the home lives small for five and expands gracefully for twenty.
