A 3-season screen room or prefab kit tends to be more affordable, while fully insulated 4-season rooms come with the highest price tags.

3-Season / Florida Screen Room Prices
A 3-season Florida screen room typically costs between $10,400 and $65,000, or about $104 to $299 per square foot. The overall cost is generally lower than other room types due to the absence of insulation and glass windows. Common designs feature a solid shingled roof with either all-screen walls or large window screens.
Other common outdoor enclosure types include:
- A screened patio enclosure costs $13 to $33 per square foot when adding screens to an existing patio.
- A screened-in porch costs $65 to $358 per square foot total.
- A screened pool enclosure costs $6.50 to $19.50 per square foot.
4-Season Florida Room Prices
A 4-season Florida room typically ranges from $26,000 to $104,000, or about $260 to $520 per square foot. The total cost depends on factors like size, materials, and design complexity. All 4-season rooms are fully insulated and seamlessly connected to the rest of the house, making them a comfortable year-round living space.
Conservatory Addition Cost
A conservatory addition costs between $65,000 and $195,000, or $260 to $780 per square foot installed. Conservatories are luxurious 4-season sunrooms, complete with insulation, HVAC climate control, electricity, and a peaked glass ceiling. This type of living space is ideal for plant lovers, as it allows more sunlight than a traditional sunroom.
Solarium/Glass Room Cost
A solarium typically costs between $39,000 and $130,000, or about $390 to $1,040 per square foot. The total cost varies based on size and whether the solarium is designed as a 3-season or 4-season addition. Solariums feature all-glass walls and roofing, with 4-season versions utilizing thicker, insulated glass for improved energy efficiency.
Prefab Florida Room Kit Prices
Prefabricated Florida room kits generally cost between $13,000 and $65,000 installed, or $26 to $195 per square foot. These prices cover materials and installation on an existing concrete foundation or reinforced deck. Total costs can vary based on the brand, size, and whether the room includes full insulation.
Factors That Impact the Cost of a Florida Room
The final cost of building a Florida room is influenced by several factors, including:
Size of the Room
The larger the Florida room, the more expensive it will be. Most Florida rooms range from 100 to 400 square feet, but even larger custom rooms are possible if you have space. A larger room means more materials, windows, flooring, insulation, and labor.
- Small Florida rooms (100-150 sq. ft.): $10,400 – $45,000
- Mid-size rooms (200-250 sq. ft.): $20,800 – $78,000
- Large rooms (300-400 sq. ft.): $31,200 – $156,000
Materials and Windows
Windows are the most critical element in a Florida room. Standard windows cost less, but energy-efficient windows with double or triple glazing will increase the price. However, they also reduce heating and cooling costs in the long run. You can expect window prices to range from $150 to $1,000 per window depending on quality and size.
- Standard windows: $2,500 – $10,000 (for a 200 sq. ft. room)
- Energy-efficient windows: $5,000 – $15,000
Other material considerations include:
- Roofing (glass or shingle): $4,500 – $12,000
- Flooring: $3 – $15 per square foot (depending on whether you opt for tile, wood, or concrete)
- Insulation: $1,500 – $4,500 (for a 4-season room)
Labor Costs
Labor is another significant cost factor, especially if you’re customizing your room. Hiring experienced professionals will ensure quality work but can increase costs. On average, expect to pay $30 to $80 per hour for labor. The complexity of the project, including electrical and HVAC installation, can raise labor expenses.
Additional Features
Adding unique features such as skylights, retractable screens, or an HVAC system can elevate the functionality and aesthetic appeal of your Florida room, but they also add to the overall cost.
- HVAC system: $3,000 – $7,500
- Retractable screens: $2,000 – $5,000
- Skylights: $1,000 – $2,500 each
Permits and Inspections
In most locations, adding a Florida room requires permits and inspections to ensure it complies with local building codes. These can cost anywhere from $400 to $1,500, depending on your municipality.
