These interior photos by Kai Fagerström depict wild forest inhabitants who have made derelict human-owned dwellings their own – domestic portraits-at-home with a undomesticated twist.

An abandoned series of small shacks and quaint cottages in Finland, slowly reclaimed by nature, show hints of slowly-invading of plant life, but the even faster introduction of woodland animals including squirrels, foxes, owls and more.

This surprising variety of crafty creatures have adopted and reshaped the existing spaces to suit their own needs, tunneling through vents and fireplaces, nesting and resting between walls and below floors.

Though this photography project started with a few quick shots in a set of cabins in the woods near the photographer’s summer home, the deserted spaces have turned out to be so rich in potential wildlife portraits that the results now populate an entire book of images (The House in the Woods).

Great patience is required to wait and take just the right desired shots, which are so well-composed you could almost imagine the animals posed to have their picture taken. “Deserted buildings are so full of contradictions [and] I am fascinated by the way nature reclaims spaces that were, essentially, only ever on loan to humans.”

Each image has a story, often elaborate, about how it was taken. About the last one above, for instance, from National Geographic: “On a summer night a family of badgers file into the kitchen from a tunnel they dug under the fireplace. It took four years before Fagerström finally caught the skittish, nocturnal weasels. For this shot he set his camera on a windowsill, then stood outside on a ladder for hours before pressing the shutter via remote control.”
