What Affects the Cost to Build a Sunroom?
Your final budget comes down to a few key choices. Here’s how to think through them.
1. Room Size & Design Complexity
- Larger rooms = more glass, structural framing, and labor.
- Multi-sided sunrooms, angled roof design, or unique architecture increase construction scope.
2. 3-Season vs. 4-Season Sunrooms
- 3-Season Sunrooms: Use lighter materials, often without HVAC or furnace systems. Great for spring through fall.
- 4-Season Additions: Insulated walls, UV-resistant glass, and complete heating/ventilation integration for year-round comfort.
3. Materials & Finish Options
- We use WeatherMaster™ windows, ideal for coastal climate exposure.
- Customize with wood finishes, painted concrete floors, built-in furniture, and ultraviolet-protective glazing.
4. Existing Structure or New Construction
- Converting an existing patio, deck, or pergola structure reduces costs on roofing, wall framing, and concrete work.
- New room additions require full-scale general contractor oversight—including plumbing, foundation, roofing, and electrical.
5. Heating, Ventilation & Electricity
- Options include ductless mini-splits, existing furnace integration, and full ventilation plans.
- Add electrical wiring for lights, fans, security, smart features, and outlets throughout the space.
6. Interior Finish & Functional Use
- Extend your kitchen, add a bathroom, or create a climate-controlled garden room.
- Choose your flooring (wood, tile, concrete) and finishes (drywall, paint, stone).
Why Coastal Construction Requires Specialized Contractors

Additionally, designing these spaces for energy efficiency ensures they remain comfortable year-round while boosting their appeal and functionality.

- Corrosion-resistant aluminum and steel framing
- Mildew-proof paint and sealants
- Impact-rated windows and ventilation support
- Licensed general contractors, electricians, and plumbing professionals on every project
