Windowed walls are buildable structures in Stranded Deep. They act as an alternative fortifying element of one's shelter, differing from the wall by the portion cut from the top to form the window. Building a windowed wall requires two palm fronds and four sticks placed next to an existing foundation, as well as the use of any kind of hammer. Two supports are also needed to keep the wall standing. Once a windowed wall is set, players are able to attach additional walls to it, provided they are able to be properly supported.
- In 0.04E2 (and possibly other versions as well) the windowed wall seem to disappear if you leave the island.
