Philadelphia's architectural history dates back to [[Colonial history of the United States|colonial]] times and includes a wide range of styles. The earliest structures were constructed with [[Log house|logs]], but brick structures were common by 1700. During the 18th century, the [[cityscape]] was dominated by [[Georgian architecture]], including [[Independence Hall]] and [[Christ Church, Philadelphia|Christ Church]].

In the first decades of the 19th century, [[Federal architecture|Federal]] and [[Greek Revival architecture]] were the dominant styles produced by Philadelphia architects such as [[Benjamin Henry Latrobe|Benjamin Latrobe]], [[William Strickland (architect)|William Strickland]], [[John Haviland]], [[John Notman]], [[Thomas Ustick Walter|Thomas Walter]], and [[Samuel Sloan (architect)|Samuel Sloan]].<ref name=Philadelphia-Page251>{{Cite book |title=Philadelphia: A 300-Year History |pages=11, 41, 174–175, 251–253 }}</ref> [[Frank Furness]] is considered Philadelphia's greatest architect of the second half of the 19th century. His contemporaries included [[John McArthur Jr.]], [[Addison Hutton]], [[Wilson Eyre]], the [[Wilson Brothers & Company|Wilson Brothers]], and [[Horace Trumbauer]]. In 1871, construction began on the [[Second Empire architecture in the United States and Canada|Second Empire]]-style [[Philadelphia City Hall]]. The [[Philadelphia Historical Commission]] was created in 1955 to preserve the cultural and architectural history of the city. The commission maintains the [[Philadelphia Register of Historic Places]], adding historic buildings, structures, sites, objects and districts as it sees fit.<ref name="PNC">{{cite web |url=http://www.phila.gov/historical/ |title=Philadelphia Historical Commission |publisher=Phila.gov |access-date=April 11, 2009 |archive-date=March 3, 2009 |archive-url=https://web.archive.org/web/20090303191207/http://www.phila.gov/historical/ |url-status=live }}</ref>

In 1932, Philadelphia became home to the first modern [[International Style (architecture)|International Style]] skyscraper in the United States, the [[Loews Philadelphia Hotel|PSFS Building]], designed by [[George Howe (architect)|George Howe]] and [[William Lescaze]]. The {{cvt|548|ft|m|0}} City Hall remained the tallest building in the city until 1987 when [[Liberty Place#One Liberty Place|One Liberty Place]] was completed. Numerous glass and granite skyscrapers were built in Center City beginning in the late 1980s. In 2007, the [[Comcast Center]] surpassed One Liberty Place to become the city's tallest building. The [[Comcast Technology Center]] was completed in 2018, reaching a height of {{cvt|1121|ft|m|0}}, as the [[List of tallest buildings in the United States|tallest building in the United States]] outside of [[Manhattan]] and Chicago.<ref name=Comcast2>{{cite web |url=http://www.visitphilly.com/articles/philadelphia/the-comcast-innovation-and-technology-center/ |title=Philadelphia's Newest Skyscraper: The Comcast Innovation and Technology Center |publisher=Visit Philadelphia |access-date=April 3, 2015 |archive-date=March 17, 2015 |archive-url=https://web.archive.org/web/20150317221032/http://www.visitphilly.com/articles/philadelphia/the-comcast-innovation-and-technology-center/ |url-status=live }}</ref>

For much of Philadelphia's history, the typical home has been the [[Terraced house|row house]]. The row house was introduced to the United States via Philadelphia in the early 19th century and, for a time, row houses built elsewhere in the United States were known as "Philadelphia rows".<ref name=Philadelphia-Page251/> A variety of row houses are found throughout the city, from Federal-style continuous blocks in [[Old City, Philadelphia|Old City]] and [[Society Hill]] to Victorian-style homes in [[North Philadelphia]] to twin row houses in [[West Philadelphia]]. While newer homes have been built recently, much of the housing dates to the 18th, 19th, and early 20th centuries, which has created problems such as [[urban decay]] and vacant lots. Some neighborhoods, including [[Northern Liberties, Philadelphia|Northern Liberties]] and Society Hill, have been rehabilitated through [[gentrification]].<ref>{{Cite journal |last=Aitken |first=Joanne |title=Breaking Ground |journal=Philadelphia City Paper |date=June 3–19, 2004 |url=http://www.citypaper.net/articles/2004-06-03/cityspace.shtml |url-status=dead |archive-url=https://web.archive.org/web/20160113222258/http://citypaper.net/articles/2004-06-03/cityspace.shtml |archive-date=January 13, 2016 }}</ref><ref>{{cite web |author=Mark Alan Hughes |title=Dirt Into Dollars; Converting Vacant Land Into Valuable Development |url=http://www.brookings.edu/research/articles/2000/06/summer-metropolitanpolicy-hughes |date=June 1, 2000 |access-date=December 24, 2013 |archive-date=December 25, 2013 |archive-url=https://web.archive.org/web/20131225175538/http://www.brookings.edu/research/articles/2000/06/summer-metropolitanpolicy-hughes |url-status=live }}</ref>
