3-Season & 4-Season Rooms

Whether you’re dreaming of a light-filled 3-season room for summer evenings or a cozy 4-season room that’s livable year-round, Beantown Home Improvements has you covered. Our expert team will guide you through every step—from design to construction—to ensure your new sunroom is built to last.

What’s the Difference Between a 3-Season and 4-Season Room?

3-Season Room

  • Designed for spring, summer, and fall use
  • Not insulated or heated
  • Lets in tons of natural light with large windows or screened in openings
  • Flooring is usually decking over screen, though not always
  • Protects from bugs, rain, and wind while staying open to fresh air
  • Cost-effective way to add living space

 

4-Season Room

  • Designed for year-round comfort and is fully insulated
  • Energy-efficient windows and doors
  • Typically heated and cooled with a mini-split system
  • Flooring is usually finished with vinyl plank or carpet
  • Perfect for a family room, office, dining space, or lounge
  • Adds significant value to your property

 

Whether you want a breezy 3-Season Room for summer evenings or a 4-Season Room for year-round living, we’ve got the expertise to bring your vision to life.

Benefits of Adding a Sunroom to Your Home

  • Expand your living space without a full addition
  • Increase natural light and outdoor views
  • Create a versatile space for dining, relaxing, entertaining, or working
  • Boost your home’s curb appeal and resale value
  • Enjoy the outdoors without worrying about bugs or bad weather

Custom 3-Season Rooms

Our 3-Season Rooms are stick frame built with durable, high-quality materials that maximize comfort and style from spring through fall. They’re designed to let you feel connected to the outdoors while staying protected from pests and the elements. A perfect upgrade for decks, patios, or open spaces that aren’t used to their full potential. And depending on your budget, we’ve even built rooms and left the interior unfinished for the homeowner to complete.

Custom 4-Season Rooms

For homeowners who want a true all-season living space, our 4-Season Rooms are stick frame built and fully insulated. They are built to function like a natural extension of your home. With energy-efficient windows, doors, and climate control options, your new sunroom will be comfortable in every season—whether it’s a snowy Massachusetts winter or a hot summer day.
