WHAT CHANCE WOULD THE KIRBY MANSION STAND TO STAY STANDING UNDER NEW OWNERSHIP? The demolition watchdogs over at Preservation Houston report that a buyer has the 36-room Midtown mansion on the corner of Pierce and Smith St. under contract and “does not intend to retain the building.” Seeking to thwart a teardown, Houston historic commission chair Minnette Boesel met with seller Phlip Azar last week — reports Nancy Sarnoff — and urged him to find someone instead who’ll keep the place upright. Aside from the house’s pedigree (built in 1894 for John Henry Kirby, it was expanded and remodeled 32-years later by architect James Ruskin Bailey), the Tudor at 2006 Smith St. has state and federal tax credits to offer any developer that renovates it for commercial use. That’s what its last would-be buyer Dennis Murphree hoped to do 3 years ago before the sale fell through. His plan: build a 15-story office tower designed “to look as much like the mansion as possible,” right next door to it — reported Sarnoff — and incorporate the 18,000-sq.-ft. house into the complex.[Preservation Houston; more info] Photo: Preservation Houston/The Heritage Society
