Tips for building an underground home include purchasing sturdy building materials, choosing a plan that matches the area in which the home is going to exist, hiring knowledgeable contractors and ensuring the home has the proper ventilation system. Builders should also focus on the layout of the underground home to ensure that it meets the needs of its occupants.
The building materials are an important consideration when working on an underground house because they affect its ability to support the weight of the ground on top of it and prevent collapses on the surrounding walls. Sturdy, solid materials also stand up better to potential erosion from exposure to the ground, which may lead to loss of insulation against cold or heat and insect or vermin infestations. The house plan also factors into this, as some designs offer more support against the environment than others.
Builders also need to make sure that the plans are suitable for the type of ground on the plot, such as soft dirt or hard, rocky land with numerous tree trunks. Hiring knowledgeable contractors is also important to ensure a high level of quality during the actual construction. While general contractors may be able to complete the process, owners may wish to hire firms familiar with underground homes. The owner also must make sure the plans and construction account for a system that properly feeds air into and out of the home to avoid asphyxiation.
