K+ has always been noteworthy in that they showcase new or under-the-radar artists from around the world. It's a lovely little space, and a therapeutic surprise in the midst of the materialistic madness that is Orchard Road. The brand of art you get here is different from what you typically see at the National Gallery or Chan Hori; it's geared towards quirky, the strange, and the melancholic.
To date, I've only visited two exhibitions, namely, Ants in Singapore (which was when I found out about this space) and The Luckier, and I thoroughly enjoyed how the artists and K+ team made said exhibitions as interactive and intimate as possible. Overall a lovely space to take a short break at, and introspect.
The space also features a gift store which showcases products from various up and coming artists, along with profound works of literature. i.e. Murakami, local writers. Artists occasionally host workshops here as well for fledging artists, and they sell out really quickly.
