Following the longest public inquiry ever undertaken in the UK,<ref>{{cite web|url=http://www.dft.gov.uk/foi/responses/2005/jan/terminalfive/planninginspectoratejournalh2291?page=2|title=Heathrow Terminal 5 Inquiry|date=January 2005|publisher=Department for Transport|archive-url=https://web.archive.org/web/20071224055842/http://www.dft.gov.uk/foi/responses/2005/jan/terminalfive/planninginspectoratejournalh2291?page=2|archive-date=24 December 2007|access-date=2 November 2007}}</ref> construction of the station was granted in November 2001 by transport minister [[Stephen Byers]] as part of the approval of the [[Heathrow Terminal 5]] project.<ref>{{Cite news |last=Harper |first=Keith |date=2001-11-20 |title=Long-awaited go-ahead for Heathrow terminal 5 |url=https://www.theguardian.com/world/2001/nov/20/transport.uk |access-date=2024-10-02 |work=The Guardian |language=en-GB |issn=0261-3077}}</ref><ref>{{Cite press release |url=http://www.thetube.com/content/pressreleases/0111/20.asp |title=Green light for Piccadilly line extension to new Terminal 5 |date=20 November 2001 |website=thetube.com |url-status= |archive-url=https://web.archive.org/web/20030203184941/http://www.thetube.com/content/pressreleases/0111/20.asp |archive-date=3 February 2003 |access-date=2020-03-10}}</ref> The proposed terminal site was not welcomed by London Underground, as it would be impossible for all three stations to be served from the same route. Instead, twin tunnels would be built from Terminals 1, 2, 3 to the new terminal.<ref>{{Cite book |last=Horne |first=Mike |title=The Piccadilly Tube – A History of the First Hundred Years |publisher=Capital Transport |year=2007 |isbn=978-1-85414-305-1 |pages=137–138}}</ref>

Construction of the extension as part of the T5 construction took 6 years, funded by [[British Airport Authority]] (BAA). As part of the construction, the Terminal 5 project team shut down two [[Hangar|aircraft stands]] from Terminal 3 so that an access shaft could be constructed. The new junction was then built into a concrete box which connected all the underground tunnels.<ref>{{cite press release |title=Tube One Step Closer for Heathrow Terminal 5 |date=14 September 2006 |publisher=[[Transport for London]] |url=https://tfl.gov.uk/info-for/media/press-releases/2006/september/tube-one-step-closer-for-heathrow-terminal-5 |access-date=17 August 2020 |url-status=live |archive-url=https://web.archive.org/web/20200817145027/https://tfl.gov.uk/info-for/media/press-releases/2006/september/tube-one-step-closer-for-heathrow-terminal-5 |archive-date=17 August 2020}}</ref> [[Heathrow Terminal 4 tube station]] was closed for 20 months between January 2005 and September 2006 to allow these connecting junctions to be constructed.<ref>{{Cite press release |title=Tube one step closer for Heathrow Terminal 5 |date=14 September 2006 |url=https://tfl.gov.uk/info-for/media/press-releases/2006/september/tube-one-step-closer-for-heathrow-terminal-5 |access-date=2020-03-10 |website=Transport for London}}</ref> Train testing started when the extension was handed over to London Underground on 18 July 2007.<ref>{{Cite web |website=Transport for London |title=First Piccadilly line trains travel to Heathrow Terminal 5|date=18 July 2007|url=https://tfl.gov.uk/info-for/media/press-releases/2007/july/first-piccadilly-line-trains-travel-to-heathrow-terminal-5|access-date=2020-09-09 }}</ref>
