This is the Domek na drzewie icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
This icon represents treehouse. It is a rectangle with a large flat bottom and a square on top. It has a wavy line all the way around the house representing a tree top. The square in the middle has a triangle top and a smaller square inside.
