After sitting idle for several years, Westwood's Flatiron-inspired Gayley at Wilshire could finally be moving forward.  A case filing from the Los Angeles Department of City Planning indicates that developer Indivest Incorporated has revived plans for the 250-key, five-star hotel tower, which would be located on a currently vacant property at 10955 Wilshire Boulevard.  Designed by Robert A.M. Stern Architects, the 29-story building would rise 427 feet, making it the tallest structure in the Westwood skyline.  First proposed before the global economic meltdown, the project site has seen little action since 2011, when its former low-rise occupant was demolished.  Since then, Indivest has patiently awaited improved economic conditions and potential tax breaks from the city.  Signs of movement on the long stalled development first appeared last year, when the developer briefly disagreed with UCLA on the terms of an alley vacation deemed necessary for the construction of the tower.  With neighboring property owners now on board, and the LA City Council doling out hotel tax breaks left and right, perhaps construction cranes are in Westwood's near future.
