Built for a couple, their two children, and their two cats, this combined residence and office on a tiny urban lot. Our research into bay windows from around the world revealed that they take many forms and play many appealing roles, from a device for bringing in light to a type of furniture for sitting on to a decorative interface with the city. Our design features bay windows on every floor and every side of the building, giving the residents many options for where to spend their time. In this tower, windows become sites for sitting, writing, sleeping, decorating, and many other activities.
