The Orange Tree Theatre in Richmond picked up four wins at this year’s Off West End Theatre Awards.
John Ramm was named best male for his performance in Sheppey , while his co-stars Josh Dylan and Dickie Beau jointly won the award for best supporting male.
The Orange Tree’s production of The Rolling Stone  by Chris Urch won the prize for best new play and Zoe Cooper was named most promising new playwright for her play Jess and Joe Forever . The theatre was also deemed to be the most welcoming in south-west London, according to a public vote.
The awards, known as the Offies, were announced by Patrick Stewart in a Twitter ceremony. Winners in 18 out of the 24 categories will be mentored for a year by ‘patron saints’ including Sonia Friedman and David Lan.
There were three awards for productions at Southwark Playhouse. Tom Hughes won best director for Punkplay , with Rufus Norris offering mentorship, best choreographer went to Lee Proud for Allegro  and Grey Gardens  won best musical.
Pop-up venue the Styx, which hosted Philip Ridley’s immersive piece Karagula , provided wins for Lynette Clarke as best supporting female and Shawn Soh for best costume designer. Sarah Ridgeway’s performance in Fury  at Soho Theatre won her the best female award.
In a new category this year, Jordan Li-Smith was named best musical director for Ragtime  at Charing Cross Theatre. He will be mentored by Mike Dixon.
Sasha Regan, artistic director of the Union Theatre, won a special achievement award “for her tireless campaign to save the theatre, negotiate with Network Rail and move the venue from one railway arch to two” .
