Transform this image to show excavation stage. Instead of the house, show a freshly dug foundation pit (котлован) approximately 1.5 meters deep in the exact footprint of the building. Raw brown earth walls visible, excavated soil piled nearby. A small excavator parked next to the pit. Some gravel and sand piles nearby. Pine forest in the background unchanged. Same camera angle and lighting. Muddy construction site. Photorealistic style.
