Four-Season Sunrooms
Year-round comfort meets natural beauty with our climate-controlled four-season sunrooms.

Enjoy Your Outdoor Space Every Day of the Year
A four-season sunroom lets you experience the beauty of nature without sacrificing comfort, no matter what the weather is like outside. Unlike three-season rooms, these fully insulated spaces are designed to keep you comfortable year-round. Whether it's a hot summer afternoon or a chilly winter evening, your sunroom stays the perfect temperature.
We build four-season sunrooms right here in Pasadena, CA, using high-quality materials that stand up to California weather. Our team handles everything from design to final installation, so you can focus on enjoying your new space. This is a great way to add living space to your home without the hassle of a full home addition.
What Makes Four-Season Sunrooms Different
The main difference between a four-season and a three-season sunroom is climate control. Four-season rooms are built with features that let you use them comfortably all year long.
- •Insulated glass windows: These keep heat in during winter and out during summer
- •Thermally broken frames: Prevent cold or heat from transferring through the structure
- •Full HVAC integration: Connect to your home's heating and cooling systems
- •Energy-efficient construction: Designed to minimize energy costs while maximizing comfort
This level of insulation and climate control makes four-season sunrooms perfect for year-round use as a home office, dining room, playroom, or simply a cozy spot to relax with a book.
Why Choose a Four-Season Sunroom
A four-season sunroom is more than just extra square footage. It's a space that brings natural light into your home while giving you the flexibility to use it however you want. Many homeowners choose to add patio enclosures first, then upgrade to a four-season design later as their needs change.
Here's what makes them worth the investment:
- •You get more usable space without the cost of a traditional home addition
- •Natural light floods the room, creating a bright and welcoming atmosphere
- •You can enjoy outdoor views without dealing with bugs, wind, or weather
- •Your home value increases with professionally installed, climate-controlled living space
