Smile and step carefully. No fewer than 16 security cameras are installed in this battened-down Braeburn Acres property, a 2007 custom design by Cameron Architects. It’s a big, big stucco-over-concrete-block house — more than 10,000 sq. ft. — with 50 stone columns supporting a double-decker carousel of arches and tile-topped rotundas. The cleared 1.2-acre lot includes a pool-in-progress and very little landscaping (other than lawn). Maybe that explains why a cartoony rendering (at top) is employed as the listing’s featured photo.
