Crawl Space to Basement Conversion (Basement Deepening)

Lot size, historical limitations, or some other constraint may lead to the determination that the conversion of a crawl space to a finished basement area is the most cost-effective way to increase the living area in a home. Also, many older homes have basements with headroom clearance that is too low to allow the basement to be finished and used as a living area. In these circumstances, it is possible to deepen the supporting foundation and concurrently mine the soil from beneath the house to create a suitable basement. This procedure frequently requires modifying the buried utilities beneath the house. It may also be desirable to modify the subfloor support system to obtain a more desirable use of space.

These combined procedures are frequently most attractive in historic, inner city areas where space is limited and "row house" style construction is common. The end result of this type of conversion is an increased heated/air conditioned living area without altering the exterior of the home.
