The business, Co-founded by entrepreneur Loui Blake, who recently debunked claims that vegan restaurants were struggling to survive, aims to open the new plant-based restaurant early next year, with a crowdfunding target of £250,000.
Since its launch in May 2018, Erpingham House has gained national recognition - listed in The Times top 20 vegetarian restaurants and featuring on Channel 4's What Britain bought'.
It served more 12,000 customers in its first year and has recently reinvested to create a bar and co-working space inside the same building.
'Invest in the future'
"Investment will go to opening our second location in the U.K's vegan capital, Brighton, which has huge demand but lacks more formal vegan dining," the crowdfund's website states.
"This is the next stage in our founding teams' plan for a national roll-out, to bring vegan dining into the mainstream. This is an opportunity to invest in the future of hospitality and our planet, to lessen our impact, and spread a more conscious way of eating out."
'Fantastic plant-based food'
In a statement sent to Plant Based News, shareholder Russell Martin, added: "I've known Loui for many years, and was incredibly excited when he came to me with the idea of opening a vegan restaurant in Norwich.
"Now, I have the opportunity to help take the fantastic plant-based food that the team at Erpingham House create to my home city of Brighton, and I can’t wait to share it with everyone."
