uIt is called a Wallipini. Underground greenhouses have been used for thousands of years by our ancestors in Meso-America (hence the name) and Europe. Often integral with the living area creating an environment that needed little extra heating in winter, and remaining cooler in a hot summer. Still used in many parts of the world. Some lovely websites on the subject, including some with detailed plans, and photos, and modern versions used as beautiful living spaces.
