1. Foundation Type
- Slab on Grade: Usually the most economical choice, but it may limit flexibility in design and future space use.
- Crawl Space: Slightly higher costs due to excavation and additional materials, but provides access to plumbing and electrical.
- Basement: Higher initial cost due to excavation, waterproofing, and additional concrete, but adds significant usable or storage space.
2. Finished vs. Unfinished Basement
- An unfinished basement offers affordable extra space with potential for later finishing.
- A finished basement significantly increases the home's value and livability but raises the price per square foot due to framing, drywall, flooring, lighting, and HVAC considerations.
