Last year, I told you about a proposed skyscraper that would be taller than the Hancock tower. I knew that Steve Belkin, the only person to submit a proposal for the site, would incorporate the adjacent office building, 133 Federal Street, that he owns into the project.

What I didn't know was that Belkin's adjacent building is the Blue Cross Blue Shield building, built in 1960 by Paul Rudolph, one of America's foremost Brutalist architects. As things stand now, Belkin has been given the right to tear down the BCBS building as soon as early next year.

Jason Hart of CUBE design + research has created an interesting proposal to preserve the BCBS building while allowing for the new tower to be built. He has created modernpreservation, a flash movie showing his ideas. I particularly like the idea of preserving the exterior of the building and melding it into the facade of the tower.

Take a look and let us know what you think!
