While $801,000 may sound like a lot for a basement den that cannot legally be used as a dwelling, it isn't unusual to see well-off Manhattanites paying top dollar for auxiliary space, said real estate appraiser Jonathan Miller.
A 100-square-foot to 200-square-foot storage room in an upper crust building could easily sell for $150,000 to $350,000, if it had a sink or its own toilet, he said.
