Then put the warehouse on the first floor and put the store on top.
Lots of big cities have grocery stores with parking garages under them, doesn’t seem much different.
Inner city high rise construction is entirely different from tip-up and bolt together single-story box stores in the suburbs.
The difference is the 100x the cost to build it and the completely different amounts of foot traffic and margins available in dense city centers. Nobody is going to build such a store if their return on investment is expected 50-100 years down the road.
