Every so often, Pioneer Square lets one of its originals go. Built in 1904 as the H.N. Richmond Paper Co. warehouse, The Lofts at 210 Third is one of the neighborhood's few authentic industrial conversions, just 17 homes, and 2C is 1,673 sq ft of the real thing: 11-ft ceilings crossed by old-growth timber beams, exposed brick, blind arches, original fir-plank floors, and classic pivot windows that fill the loft with gallery light from morning to dusk. The rarities are already handled: deeded garage parking, central A/C, two 3/4 baths, and live/work zoning that welcomes a residence, studio, or showroom. The wide-open footprint is a ready canvas. Build the marble-island kitchen or the boutique-hotel suite this space deserves; the bones cannot be built again at any price. Outside the door: First Thursday Art Walk, the waterfront, T-Mobile Park, and light rail, all within blocks (Walk Score 98). A century of Seattle made this loft. Finish it your way.
