This 120 year old row house at 1237 Union St in Crown Heights reveals Brooklyn's transformation from farmland and dirt roads to a thriving metropolis with street lamps, fire hydrants and underground subways.    Why even its accommodations suggest that Architects of the era knew families needed more practical sized bedrooms and closets to satisfy the borough's fast growing middle class at the turn of the century.    With its 1,520 sq ft duplex providing a spacious living room, impressive dinning room, eat in kitchen and 3 roomy bedrooms at its top floor, you'd think families in that era would have had their expectations met.    But this home boasts a fully above grade english basement with separate entrance from its front and back yards, delivering an additional 750 sq ft of living space for homeowners that want a place for relatives or guests to stay in (especially since its equipped with its own kitchen and bathroom).    We'll make this easy for you.
