Marylebone Cricket Club (MCC) is currently working with turf consultant Steven Pask Limited to add two new pitches to the main Lord’s square.
One pitch is being laid at either end of the square, and both will initially be used during the 2013 season for training and practice purposes prior to international and First-Class fixtures.
Watch: Lord’s square extended
Following a two-year “bedding-in” process, it is intended that the pitches will be used in competitive cricket from 2015.
The addition of the new pitches means that the Lord’s square will incorporate 21 pitches.
Work was last conducted on the Lord’s square in September 2004, when one of the pitches in the middle of the square was re-laid.
Head of Cricket, John Stephenson, said: "The laying of two new international standard pitches represents the most recent phase in the Club’s ongoing commitment to ensure that Lord’s remains world-class, as well as world-famous."
