Griffin Park & Brentford Community Stadium

Brentford announced in October 2002, while still playing at Griffin Park and after several years of speculation about a move, that it planned a 20,000-capacity stadium near Kew Bridge; the scheme's monorail proposal was later dropped. The project returned to public attention in late 2007 when the club said it had secured an option on the site, and in February 2008 it announced a partnership with Barratt Homes to develop it.

On 28 June 2012 the club bought the 7.6-acre site off Lionel Road from Barratt Homes, which had acquired it in January 2008, aiming at a 20,000-seat ground for the 2016-17 season with the option of extending to 25,000. Hounslow Council approved the stadium in December 2013, and further approval was sought and received from the Mayor of London and the government the same month. Acquiring the rest of the land, needed for the enabling development of flats, took longer: a compulsory purchase order was approved in the summer of 2014, objections forced a further hearing in September 2015, and the order was approved in April 2016 and completed on 1 September 2016. The development agreement with Willmott Dixon had been signed in December 2014.

Work began on 24 March 2017 with site clearance and preliminary works, and the main works in spring 2018, on a plot in the middle of a triangle of railway lines beside Kew Bridge railway station. An amended application allowing rugby union as well as football had been passed on 9 February 2017, after London Irish said in August 2016 that they were discussing a move from Reading back to the capital as Brentford's tenants. On 30 August 2020 the club confirmed the stadium was complete and ready to host football matches; the ground holds 17,250 and is built for both association football and rugby union.

The first match, a pre-season friendly on 1 September 2020, ended 2-2 against Oxford United after Sergi Canos scored twice to put Brentford 2-0 up. The first competitive fixture, an EFL Cup first-round tie against Wycombe Wanderers on 6 September, finished 1-1 with Ethan Pinnock opening the scoring, and Brentford won the shoot-out 4-2. Their first league game there, on 19 September, was a 3-0 win over Huddersfield Town with goals from Josh Dasilva, Bryan Mbeumo and Marcus Forss. London Irish played their first match at the ground on 29 November 2020, beating Leicester Tigers 22-9, Curtis Rona scoring the opening try.

Over the summer of 2022 the whole of the West Stand and the north-east corner were converted to rail seating for safe standing, made possible by a government change licensing it after a successful government-commissioned trial the previous season. On 28 July 2022 the club announced a ten-year partnership with the British technology manufacturer Grey Technology that included naming rights, and the ground became the Gtech Community Stadium.

It was one of the venues for the UEFA Women's Euro 2022, staging the Group B matches Germany against Denmark on 8 July, Germany against Spain on 12 July and Denmark against Spain on 16 July, and the quarter-final between Germany and Austria on 21 July.

England played Australia in a women's international friendly at the ground on 11 April 2023. London Irish were suspended from the league ahead of the 2023-24 Premiership Rugby season and subsequently entered administration. In 2025 the stadium held the Unity Cup, contested by Ghana, Jamaica, Nigeria and Trinidad and Tobago, which Nigeria won on penalties, two Brentford players, Benjamin Frederick and Frank Onyeka, playing in the final for Nigeria.
