A "look-out rafter" is a type of beam that protrudes from the roof of a building and is meant to act as a lookout point or observation post. It allows for a wider view of the surroundings and is often found on traditional colonial-style homes. Synonyms for this type of beam include a lookout beam, outlook rafter, roof lookout, and perspective beam. In addition, it can be referred to as a crow's nest or an eagle's perch, both of which suggest a higher vantage point. Ultimately, these synonyms all describe a feature that provides a unique viewpoint and adds character to the roofline of a building.
