- Foundation
- A slab or reinforced foundation for a heated room costs more than a simple deck-style base for a three-season room.
- Glazing extent
- More glass and higher-performance windows raise both cost and comfort.
- HVAC tie-in
- Extending heating and cooling into the room is what makes it count as living space — and adds cost.

How to read these United States figures. The cost is the US national midrange benchmark adjusted by a Miami, FL cost multiplier (1.08×) and shown in USD. The “% recouped at resale” is a national (US-derived) Cost-vs-Value benchmark applied to the local cost — it is not a locally measured resale figure, and real recovery varies by United States market conditions.
