Mongolia like Geography?

I wanna try my hand at a world building project where I construct a few houses and workplaces, and then imagine a culture that would live and work there

This time, I wanna combine Proto-Indo-European style huts with the geography of Mongolia

For a more specific description than just an image, a grassland/plains biome to the north, with a vast desert to the south with a few large mountain chains to the west

A few sparse rivers or large ponds/small lakes would be useful as well

Obviously this won’t be the only biome in the map, but having a majority of it composed of temperate grassland and desert would probably be enough to get the idea across

Thank you for your time and consideration
