Over the course of the next three years, the Ricketts family began to purchase many of the rooftop locations. 1060 Project renovation Phase one of the 1060 Project began on September 29, 2014. During the offseason, the bleachers in both outfields were expanded and the stadium's footprint was extended further onto both Waveland and Sheffield Avenues. A Jumbotron scoreboard was added to the left field bleachers, topped with a sign advertising Wintrust Financial, a Rosemont-based bank and a Cubs Legacy Partner; the "W" in Wintrust flashes after every Cubs win. A video scoreboard was also added in the right field bleachers, and the parking lots along Clark Street were excavated for underground players' locker rooms and lounges. After the close of the extended 2015 season, work began on phase two of the project. Exterior renovations of the park seek to restore design elements present before the 1960s. These details include ornamental muted-green grill-work and red terra cotta roofing. Phase three of the 1060 Project was completed before the start of the 2017 season. The left and right field bullpens were relocated to enclosed areas under the bleachers, the brick walls were extended toward the field, and new seating was added in the vacated bullpen areas. A visiting team "batting tunnel" was also added. Partial façade replacement and concourse restoration was completed along Addison Street, along with structural improvements to the right field bleachers. The outfield turf was replaced just weeks before the start of the season. The Cubs Plaza building just to the west of Wrigley was finalized, and the "Park at Wrigley", the area above Cubs players dressing rooms, was in use for fans before and during games. Construction of Hotel Zachary along the west side of Clark Street was ongoing. The fourth phase of improvements began at the conclusion of the 2017 season. The dugouts were moved farther down the left and right field foul lines to make room for two of the four new luxury clubs. The seating area behind home plate was reconstructed to locate another of the new clubs. The final upper level club was planned for the 2019 season. The Hotel Zachary, just across Clark Street, was open for business in time for the Cubs' first home game on April 9, 2018. National Historic Landmark Near the start of the renovations, the Ricketts applied for National Historic Landmark status for Wrigley Field in 2013.
