Turning onto King Street from Main, one is struck by the magnificent yellow Victorian now owned by a first-time homebuyer with a business at 800 Main. No longer is the building dilapidated, with a very large hole in the roof; no longer is there talk about tearing it down and creating another trash-strewn lot in this residential neighborhood. Rather, 9 King is among the half-dozen restorations along King Street to be completed by Worcester Community Housing Resources, “Mathew 25,” Worcester Common Ground and other developers.
