The Open Door event will take over Old Spitalfields Market in east London from 6-8 May.
The brand is promising an interactive shopping experience, where attendees will be able to choose from a variety of entry points, each of which will lead them to a unique themed retail space.
The different areas will reflect the brand’s primary categories, such as prints, art and homewares, garden accessories and health and beauty.
Products from more than 100 of Not On The High Street's stockists - namely small, creative businesses - are expected to be on show over the three days.
A number of sellers will also deliver free demonstrations and workshops throughout the period, such as food and drink tastings, hula-hoop sessions, creative workshops and live music.
Those interested in attending a workshop are encouraged to secure their space via the brand's dedicated Open Door microsite, which launched today (18 April).
Not On The High Street on 'Man dash Monday' last year, to assist those yet to purchase Christmas presents for their loved ones.
