The construction project at the corner of Water and Gay streets in Baltimore will yield 312 upscale condominiums when it is completed in the fall of 2007.

The developer, Bush Construction Corp., has already sold two-thirds of the “414 Water Street Condominiums,” which range in price from the low $200,000s to $600,000, said Andrew Viola, vice president and regional manager of the Williamsburg, Va.-based developer. Some of the units feature harbor views and two bedrooms, a den and 2.5 baths.
