Root Cellar Construction Costs: What To Expect?

Design and Materials

When building a root cellar, it’s essential to consider the design and materials that will help regulate the internal temperature and humidity levels. A well-insulated root cellar with a thick layer of insulation (such as 4-6 inches of foam board) and a waterproof membrane can maintain a consistent temperature between 32°F and 40°F (0°C and 4°C). The walls, floor, and ceiling should be made from durable materials such as concrete, brick, or stone, which can help to regulate temperature and humidity. A basic root cellar design can be built with a single door and no windows, while a more advanced design may include additional features such as a ventilation system, shelving, and lighting.

Temperature and Humidity Control

To maintain the optimal temperature and humidity levels in the root cellar, it’s crucial to control the air circulation and moisture levels. A ventilation system that includes a fan and a valve can help to regulate the air exchange and prevent moisture buildup. The root cellar should also be designed to allow for some airflow to prevent the buildup of ethylene gas, which can cause produce to ripen prematurely. A typical ventilation system can cost around $500 to $1,000, depending on the size and complexity of the design.

Storage and Shelving

The storage and shelving system in the root cellar should be designed to maximize the storage space and keep the produce organized. Shelves made from durable materials such as wood or metal can be installed at different heights to accommodate various types of produce. A typical shelving system can cost around $1,000 to $2,000, depending on the size and complexity of the design. Additional features such as baskets, bins, and crates can also be used to store produce and keep it organized.
