Nestled down the road from Facebook's Menlo Park, Calif., headquarters, Instagram since September has been settling into its newly expanded home. Previously occupying just one floor of its building, Instagram's three-story HQ was a blank slate for the company to make its own. With 345 of its nearly 400 global employees based at the location, as well as high-level visitors shuffling in and out every day, it was imperative that the office reflect the look and feel of the photo-sharing app. Designers carved out a space that was intended to feel like a 3-D version of the app, complete with photo sets, instant cameras and rotating displays of aspirational photos. "We set out to design an experience that would be inspiring for us to walk through every day," explained Instagram design head Ian Spalter. "Our goal was to carry through the aesthetic of the app—a clean, light, modern space with pops of color provided by galleries of photos, videos and community stories that reflect and showcase the diversity of expression on Instagram."
