The 7,200ft site is off Shaftesbury Avenue, spread across two floors and is set to open in October.
It will have capacity for 450 guests and seating for 200 with the aim to be the ultimate bar to watch, play and party late into the night.
Arc co-founder and CEO Martin Wolstencroft said: “Announcing our presence in London is a huge step for Arc Inspirations.
“After achieving success across our existing locations, having the opportunity to open our first venue in London is a milestone moment for the group.
“We are extremely proud of what we have built with our Box concept, with Box Nottingham recently being awarded Best New Site at the 2025 Publican Awards.
“We now can’t wait to bring our award-winning bar to the capital.”
Company financials
Earlier this year, the business reported sales growth over the festive five-week period in 2024.
Average sales hit a record £106,000 per venue across its venues during the peak December week as total sales reached £2m.
Last year also saw the group open Manahatta cocktail bars in Edinburgh and Nottingham as well as a Box venue in Sheffield, south Yorkshire.
In March, Wolstencroft spoke at The Morning Advertiser‘s MA Leaders Club event in York.
He outlined his thoughts on changing consumer behaviour in the different day parts.
Changing behaviour
Wolstencroft argued Millennials are adhering to the reported trend of going out earlier in the day and home earlier but Gen Z are going out later, meaning there is an opportunity to adapt offers to suit at least two generations.
He also added that brunches were big for the older generation, beginning at about midday.
Arc’s brunch offer has altered to change Gen Z, the company boss said, by offering healthier cocktail options for example.
He added: “It’s about offering a really great experience and elevate it but keep your costs down.”
