The &lsquochang&rsquo in the name alludes to the stilts on which these bungalows&mdashalso called &lsquochang ghars&rsquo&mdashwere built, to protect against the flood waters of the Brahmaputra and to keep wild animals, especially creepy crawlies, out. More than a century old, Mancotta Chang served as the superintending manager&rsquos bungalow before the owners&mdashManoj and Vineeta Jalan, who belong to one of the oldest tea-growing families in Assam&mdashconverted it into a heritage stay about two decades ago. It has been spoiling guests with old-world service since then.
