Is the other side going to remain tiled?
One option is to get a flooring person to match color/stain and put the new boards perpendicular to the old floor.
The more costly/more work option would be to remove sections of the old hardwood, add extra pieces that are matched (like the other option) and restagger the floor. You don't want to just add more hardwood have have a not staggered seem were old meets new.
Hope that makes sense. But in either case, I think it's possible.
