Windows are much more than just panes of glass in Anders Berensson Architects’ latest project in the Stockholm archipelago. The architects recently completed Look Out Lodge, a house extension built of locally sourced materials that functions like a standalone cabin. Custom-made prefabricated windows added in the second phase of the project define the areas for sleeping and working, all the while immersing the owner in nature.

Clad in timber inside and out, Look Out Lodge was built on-site using local materials and building techniques. The two window additions—a Sky Tower and desk window—were prefabricated on site and slotted into place after the primary structure was completed. The small house extension is just large enough to accommodate a sleeping area and workspace. “Another goal with the design was to redefine the idea of a window as a flat readymade glass piece into an architectural element that creates its own space with a clear focus towards the outside,” wrote the architects. “This goal led to the design of a sky tower one can crawl into when being in bed totally dedicated to the sky and one corner window with a desk inserted to it that creates a work space on the inside and table for flowers on the outside with a clear focus and direction to the outside field.”

The architects designed the Sky Tower to give the homeowners the countryside luxury of falling asleep beneath a starry sky. Topped with a round skylight and lined with spruce, the Sky Tower wraps around a custom-built bed and provides the perfect space to read during the day and for stargazing at night. The exterior draws on the local tradition of jigsaw facades and is punctuated by a pattern of native fauna and flora including large animals, amphibians, birds, flowers, and fish.

The Desk Window prefabricated element is a corner unit that frames views of a wildflower meadow, one of the most beloved features of the Stockholm archipelago. The desk unit features a solar shade and a red terra-cotta concrete slab with holes for flower plants on the outside of the window, while a curved birch plywood tabletop with a round cut-out for sitting is located on the interior. Holes drilled into the desk are made for different purposes, including ventilation, cables, lamps, pencils, and even for pencil sharpening.
