Grand Mastiff Art House was born in Tønsberg, Norway in 2020, as a popup gallery for galleries, artists and musicians/bands with and without diplomas. For us, it is really about the art and the artist. We represent educated as well as self-taught artists. 

Grand Mastiff Art House opened in the very start of the pandemic, with no people roaming the streets or having any refill of cultural input.
Founder Hege Holt had recently returned home from 16 years in the Caribbean, doing exactly this. The gallery was born in partnership, but is today solely owned and developed by Hege Holt.

Our game is:

• Business development
• marketing
• branding
• events
• popups  

Our focus is on development for artists and musicians, but on occasion we take on other types of projects, as the concepts tie in to creativity and art.

In 2026 we have had 7 popup gallery projects, and we work daily to help brands to the next step, finding more business, and to a developed a professional expression of their business, 

Welcome to Grand Mastiff Art House.
