Three-Season Sunrooms
Affordable sunroom solutions for spring, summer, and fall enjoyment.

A three-season sunroom gives you a comfortable outdoor living space for most of the year without the higher cost of a fully insulated four-season room. If you live in Burbank and want to enjoy your backyard during spring, summer, and fall, a three-season sunroom is a smart and affordable choice. At BSP Burbank Sunrooms & Patios, we build high-quality three-season sunrooms that let you relax and entertain in comfort while staying protected from bugs, rain, and sun.
What Is a Three-Season Sunroom
A three-season sunroom is a semi-enclosed space that provides protection from the elements without the full insulation and climate control of a four-season room. These sunrooms typically feature large windows, a solid or screened roof, and a simple foundation. They are not designed for extreme temperatures, so they work best in mild weather.
In California, where winters are relatively mild and summers can be hot, three-season sunrooms are a popular choice. You can use your sunroom comfortably for 8 to 10 months of the year, making it a great space for family gatherings, reading, hobbies, or just relaxing with a view of your yard.
Benefits of Three-Season Sunrooms
Three-season sunrooms offer several advantages that make them an attractive option for homeowners on a budget or those who do not need year-round climate control. Here is why you might choose a three-season sunroom:
- Lower Cost: Three-season sunrooms are more affordable than four-season rooms because they require less insulation and simpler construction.
- Faster Installation: With fewer materials and simpler design, three-season sunrooms can be built in 1 to 3 weeks.
- Natural Ventilation: Many three-season sunrooms include operable windows and screens for fresh air circulation.
- Bright and Airy: Large windows and open designs create a light-filled space that feels connected to the outdoors.
- Low Maintenance: Simple construction and durable materials mean your sunroom requires minimal upkeep.
- Added Living Space: Even though it is not used year-round, a three-season sunroom still adds valuable square footage to your home.
If you want to expand your living space without breaking the bank, a three-season sunroom from BSP Burbank Sunrooms & Patios is a practical and cost-effective solution.
Design Features and Options
Even though three-season sunrooms are simpler than four-season rooms, you still have plenty of design options to create a space that fits your style and needs. We work with you to customize your sunroom with the features you want.
Window Styles
Choose from sliding windows, casement windows, or fixed glass panels. Operable windows allow you to control airflow and keep your sunroom comfortable on warm days. We use high-quality frames and glass that resist fading and weather damage.
Roofing Options
Three-season sunrooms can have solid roofs, glass roofs, or a combination. Solid roofs provide shade and protection from rain, while glass roofs offer beautiful views and natural light. We help you choose the best option based on your preferences and budget.
Flooring and Finishes
Your sunroom can have tile, wood, laminate, or stained concrete flooring. We also offer interior trim and paint to match your home. Our finishes are durable and easy to clean, making your sunroom a low-maintenance addition to your property.
Three-Season vs Four-Season Sunrooms
Deciding between a three-season and four-season sunroom depends on your budget, how you plan to use the space, and the climate in your area. Here is a quick comparison to help you choose:
Three-season sunrooms are ideal if you want an affordable outdoor living space that you will use during warmer months. They cost less to build and maintain, and they still provide protection from bugs, rain, and sun. However, they are not suitable for extreme heat or cold, so you may not use them during winter.
Four-season sunrooms, on the other hand, are fully insulated and climate-controlled. They cost more upfront but offer year-round comfort and can be used as a true extension of your living space. If you need a home office, guest room, or family room, a four-season sunroom is the better choice. We also offer sunroom conversions and upgrades if you decide to upgrade your three-season sunroom later.
