What is a sunroom?
How much does a sunroom cost?
A sunroom is a glass-enclosed living space that allows natural light in while offering protection from the elements. It can be three-season (not insulated) or four-season (fully insulated and climate-controlled), depending on how you plan to use it.
The cost varies based on size, materials, insulation, and whether it's a three- or four-season build. On average, sunrooms range from $20,000 to $80,000+. We provide detailed quotes based on your specific needs and site conditions.
What’s the difference between a three-season and four-season sunroom?
-
Three-season sunrooms are ideal for spring, summer, and fall. They are not fully insulated or heated.
-
Four-season sunrooms are built with insulated walls, floors, and double- or triple-pane windows, making them usable year-round.
Our Process - Built Around You
Personalized Design Consultation
We begin by understanding your vision, lifestyle needs, and architectural preferences. Whether you're looking for a traditional three-season sunroom or a fully insulated four-season addition, our team works with you to design a space that complements your home and enhances your daily living.
Seamless Integration with Your Home
A sunroom should look and feel like a natural part of your home. We pay close attention to details like matching siding, roofing, trim, and interior finishes so that your new space blends beautifully with your existing structure.
Energy Efficiency and Comfort
We prioritize insulation, thermal breaks, and high-performance glass to create a space that stays cool in the summer and warm in the winter—minimizing energy costs while maximizing enjoyment.
Transparent Project Management
We understand that home construction projects can feel overwhelming, which is why we prioritize clear, consistent communication from start to finish. Our team keeps you informed at every stage—providing updates on timelines, budgets, and progress—so you always know what to expect.
