The event, held on Thursday (April 28), celebrated the theatre's successes over the last year since its capital redevelopment finished in April 2015.
The development included the construction of the Reuben Foundation Wing, housing a range of state of the art facilities including rehearsal, dance, digital, film and recording studios.
The existing building was re-furbished with a new Peyton and Byrne café and bar, and now benefits from improved sustainability and disabled access.
The Lyric celebrated its most successful box office year to date with 158,964 people attending 639 performances at the venue, with both Bugsy Malone and the Christmas pantomime Cinderella playing to over 90% capacity. Bugsy Malone will be returning to the theatre this June .
The theatre has also continued to demonstrate its commitment to environmental sustainability , as it was in January 2016 awarded the highest level three-star Creative Industry Green Certificate for 2014/2015 for the fourth year running.
Speaking to getwestlondon before the launch of the redevelopment, Jessica Hepburn, then executive director of the Lyric said: "There are two parts to the Lyric's mission, one of which is producing theatre professionally, the other is developing work with young people and emerging artists.
"That's been very much our mission that we've been building over the last few years and now we have this palace to deliver it all in.
"Fundamentally we're about delivering activities very cheaply or free for local young people... and putting on great shows for everyone."
