In our forthcoming book, we talk a lot about how easy and rewarding it is to build a collection of great objects that add texture and personality to your interior. What's always been so much harder is building a collection of great art. That's why we were so excited to discover the David Zwirner–backed online art marketplace Platform last November, which lets anyone purchase high-end works by respected artists for relatively accessible prices, and with just the click of a button. A year later, we've partnered with the site to create our own collection of Sight Unseen–approved artworks that will instantly make your space more colorful and more visually interesting — most of which are under $5k.
