Adding a Basement to Your Barndominium
Barndominiums — combining classic metal pole barns with modern dwelling finishes — continue rising exponentially in popularity thanks to abundant interior space, cost-effective construction, and flexible customization potential. And what custom barndo addition allows even more living area and storage? A fully finished basement level opening opportunities for man caves, home gyms, storm shelters and more beneath your fresh country retreat.
Basement Building Considerations
Adding a full subterranean level to a barndominium takes more forethought, expense and specialized equipment versus building a barn home slab-on-grade style. Several key steps set the stage for basement success.
First, assess soil types across your rural building site through geological surveys. Clay-heavy soils often complicate excavation while sandy soils require shoring during the digging process. Bedrock presence also influences feasibility based on depth and hardness.
Second, factor added permitting, inspections and zoning law considerations that differ from jurisdictions without basements. Your contractor handles much of this but code familiarity assists planning.
Finally, budget 15-25% more upfront for the excavating, waterproofing, concrete pouring and structural supports needed in this more complex foundation methodology.
Specialized Basement Construction
Once adequate groundwork research completes, specialized equipment moves in for digging out an entire sub-floor cavity including the footers. Soil gets hauled away before commercial dewatering systems drain any existing groundwater interference. Forms then custom cut heavy-duty concrete designed to withstand soil and moisture pressure get reinforced with steel and poured before waterproof sealing application.
With the underground foundation and walls cured, the prefab metal structure barn itself gets anchored securely into the poured slab and wrapped for moisture resistance. Interiors finish like any ground level barndo with framing, drywall, paint, flooring and desired amenities. Expect the upgrade to add 4-6 months over a typical build.
Reap the Basement Rewards
By tackling important logistics beforehand plus budgeting extra, adding full living basement space unlocks rewarding potential including:
– Expanded square footage for gyms, theaters, second kitchens etc.
– Built-in storm/tornado shelters and secured storage
– Temperature insulation and energy efficiency
– Added resale value from 30-50% more space
With smart planning and partnership with specialized contractors, subterranean barndo living surpasses expectations!
