The Reyes Building is just a shell of its former self, a circa 1889 storefront that housed the once-bustling Paso del Norte, an early Mexican cafe that catered to all the folks who frequented the markets, resale shops and little businesses in the 2100 block of Larimer Street. But after a fire hit the building over a decade ago, it sat boarded up, a blight on the ever-brightening Ballpark Neighborhood. And then along came Karle Seydel, former head of the Ballpark Neighborhood group, who'd watched all the development going on -- and up -- in his back yard and decided to get in on the game, too. But he did it right. Working in conjunction with the building's owners, Marcellino and Elisa Reyes, Seydel stripped the structure down to its initial components and is building two lofts and commercial space into an essentially new building that will fit right in with the character of Larimer Street's old roots. What's new is old again.
