CityCenter (also known as CityCenter Las Vegas) is a 16797000 sqft mixed-use, urban complex on 76 acre located on the Las Vegas Strip in Paradise, Nevada.
 The project was started by MGM Resorts International; Dubai World became a joint partner during the project's construction phase.
 It is the largest privately funded construction project in the history of the United States.
 The project is connected by a people mover system to adjacent MGM properties Monte Carlo Las Vegas and Bellagio Las Vegas.
 As of 2015, the "CityCenter" branding has been largely retired, with the focus instead on the Aria brand of the development's centerpiece property in names such as the "Aria Express" (formerly "CityCenter Tram") and "Aria Art Collection" (formerly "CityCenter Art Collection").
Five Penn Center is a 36-story highrise in downtown Philadelphia, Pennsylvania.
 It is part of the Penn Center complex designed by Edmund Bacon.
 The building was one of the tallest in the city until the highrise building boom of the late 1980s and early 1990s and is connected via underground concourse to Suburban Station, as are all buildings in the complex.
The Harmon was a highrise building at the CityCenter development in Paradise, Nevada.
 The tower was designed by Foster + Partners as a non-gaming boutique hotel, and was to be operated by Andrew Sasson's The Light Group upon completion.
 The building featured an elliptical layout and highly reflective exterior located on the northeast corner of the project at the intersection of Las Vegas Boulevard and Harmon Avenue.
 Significant construction defects in the building were discovered in 2008, and the project was halted indefinitely.
 On August 23, 2013, a Clark County court approved the tower's demolition.
 The dismantling of the tower began in the summer of 2014 and completed in the fall of 2015.
150 North Riverside Plaza is a highrise building in Chicago, Illinois, completed in 2017.
 The building is 53 stories tall.
 The building occupies a two-acre site on the west bank of the Chicago River, whose size and location demanded an unusually small base for the building.
 The building features 1.2 million square feet of leasable office space.
 Due to its unique superstructure design, it encompasses just 25 percent of the lot.
A microclimate is a local set of atmospheric conditions that differ from those in the surrounding areas, often with a slight difference but sometimes with a substantial one.
 The term may refer to areas as small as a few square meters or square feet (for example a garden bed or a cave) or as large as many square kilometers or square miles.
 Because climate is statistical, which implies spatial and temporal variation of the mean values of the describing parameters, within a region there can occur and persist over time sets of statistically distinct conditions, that is, microclimates.
 Microclimates can be found in most places.
The Pinehills is a census-designated place (CDP) located in the Pine Hills region of Plymouth, Massachusetts, United States.
 As of 2008, the project is the largest new residential and commercial development in New England.
 When complete, The Pinehills, a mixed-use community, will include 1.3 million square feet of mixed-use space and 3,065 homes on only 30 percent of the land, preserving over 2,200 acres of open space over an area of 3060 acre , an area larger than many Massachusetts towns.
 Already, over 500,000 square feet of mixed-use space exists in the Village Green.
 The community now consists of over 2,000 single-family homes, apartments and condominiums, two daily fee public golf courses, a private golf club, and the Village Green, a commercial center with a grocery store, restaurants, US Post Office, shops and professional and medical services.
 At the 2010 census, the population was 955.
