Brentford Football Club has pushed back the move-in date for its new stadium to the start of the 2020/21 season.
The west London team had planned to move into the ground, being built by Buckingham Group and developer EcoWorld London, in December 2019.
Brentford said it had taken the decision in anticipation of the “normal delays and problems that inevitably arise in a complicated construction project”.
Other factors cited by the club for the delay were the complexity of the site, which is bounded by railway lines on all sides, and that a mid-season switch of venue presented “operational challenges”.
Work on the stadium project, which also features a 910-home development, has been under way for more than four months, with piling works for the foundations now “90 per cent complete”, according to the club.
Brentford added that the first parts of the stadium’s steel frame were in place and sections of terracing on the south had begun to be laid.
At a meeting between community groups and project stakeholders in May, project manager Paul Mackenzie set out the scheme’s anticipated timeframe.
He said the stadium’s frame would be complete by February 2019, followed by the facade in April and the pitch by August, in time for test events at the ground throughout November and December.
Mr Mackenzie revealed that the work on the pitch could only take place at the end of the project, as it served as a through route and waiting area for delivery vehicles.
Minutes from the meeting also revealed that construction of the residential development was interlinked with the stadium and therefore subject to the same deadlines.
The project to build Brentford’s new stadium finally got under way this year following a three-year delay.
Plans for the 4 ha development were first approved in June 2014, with planning permission granted for a 20,000-seat stadium, 910 homes, a 160-bed hotel and commercial space.
However, it took until September 2016 for local authority Hounslow Borough Council to acquire the necessary compulsory purchase orders of land to allow the stadium to go ahead.
