Adding a sunroom is one of the most rewarding ways to expand your home. It brings natural light, extra space, and a seamless connection to the outdoors — while also boosting property value. Whether you dream of a cozy morning retreat or an elegant family space, understanding what’s involved in a sunroom addition helps you plan smarter and invest better.
Here are 12 essential things to know before adding a sunroom, brought to you by Liangjia, a trusted manufacturer of custom aluminum sunrooms.

Define Your Purpose First
Think about how you plan to use the space — for reading, dining, entertaining, or working. Your purpose will determine the structure, materials, and insulation needed.
Choose Between Three-Season and Four-Season Designs
Three-season sunrooms are perfect for mild climates, while four-season sunrooms are designed for year-round comfort.
Liangjia aluminum sunrooms offer excellent insulation, weather resistance, and durability.
Check Local Building Codes
Every region has its own permit rules and safety standards. Always check them before starting construction.
Plan Your Budget Wisely
A sunroom addition typically costs between $20,000–$70,000, depending on size, design, and materials. Include foundation, wiring, and interior finishing in your plan.
Select the Right Frame Material
Aluminum is the most popular choice — strong, rust-proof, and low-maintenance.
Liangjia specializes in custom aluminum sunrooms that combine modern style and durability.
Use Energy-Efficient Glass
Choose double-glazed or Low-E glass to maintain a comfortable temperature and reduce glare.


Ensure Proper Insulation and Ventilation
Insulated walls and roofs keep the room comfortable year-round, while ceiling fans or vents promote airflow.
Match the Style to Your Home
Your sunroom should look like part of your home. Match rooflines, colors, and windows for a seamless appearance.
