Elderly housing would prob be relevant considering our state is #2 for oldest population, as well as its proximity to still-standing shopping centers. The malls-to-housing concept has been implemented in other parts of the country too. I don't think forcing more retail into a place where it already failed is the way to go... NH residents are hungry for services that actually benefit and enrich their lives. It's no coincidence that two of their only existing tenants are a gym and a trampoline park lol.

Fun fact, the rooftops of the Steeplegate Mall is an ornithologist observation site for endangered nighthawks.
