The Maxis House on a Hill window, centered in the middle of two tiles. Plus a tagfix override for the original that changes the colour tag on the very light wood version to BrownLight, and on the light grey to Grey (they are both tagged as White by default).
All textures + footprint and so on are referenced from the game files, so this is of no use without GT. The screenshot below shows the window in combination with the Separated Window Shutter from here.
Same price and colour options as the original.
Polygon Counts: Unedited.
