Sunroom vs. Full Room Addition: Which Adds More Value?

Understanding which home addition will add more value to your Bangor property is crucial.

Full-room additions add more square footage to your home and have a higher return on investment (ROI).

According to Remodeling Magazine’s 2023 Cost vs. Value report, the ROI for additions ranges from 22% to 30%.

The reason sunrooms do not add as much value to your home is because sunrooms are typically not included in a home’s total square footage, which appraisers use to assess property values.

However, sunrooms can also be beneficial, especially for enjoyment and certain climates.

Full-Room Additions

A full-room addition is a great way to increase the usable floor space of your home.

This type of home improvement involves traditional construction methods, adding substantial square footage and enhancing the home’s functionality.

  • Square Footage: Fullroom additions add significant floor space to your home. Whether it’s a new master bedroom, a guest bedroom, or an in-law suite, these additions can greatly enhance your living spaces.

  • High ROI: Full-room additions typically offer a higher return on investment compared to sunrooms. Since they are considered part of the home’s total square footage, they can significantly boost your property’s value.

  • Year-Round Use: These additions are well-insulated and connected to the home’s HVAC system, making them suitable for use throughout the year.


Sunrooms offer a bright, airy alternative to traditional room additions.

They are perfect for those who love natural light and want a versatile space to enjoy the outdoors while being indoors.

  • Cost-Effective: Sunrooms generally cost less to build than full-room additions, making them a popular choice for those looking to save money.

  • Flexible Use: These spaces can serve multiple functions, such as a family room, dining room, or hobby area. Their versatility makes them a valuable addition to any home.

  • Natural Light: One of the biggest draws of sunrooms is the abundance of natural light they provide. This can make your home feel larger and more welcoming.

Cost Comparison

The cost of a home addition or sunroom typically ranges based on size, materials, and labor costs.

In general, the cost per square foot for home additions (including sunrooms) ranges broadly from $200 to $375.

Sunrooms are typically on the lower end of this spectrum, while full-room home additions are generally more expensive.

However, the cost of either option can vary widely based on the size and scope of the project.

When deciding between a sunroom and a full-room addition, consider your specific needs, budget, and how you plan to use the new space.

A full-room addition offers more square footage and a higher ROI, making it ideal for those looking to increase their home’s value significantly.

On the other hand, a sunroom provides a cost-effective way to add a versatile and light-filled living space to your home.

Types of Sunrooms

Adding a sunroom to your home can provide a delightful living space filled with natural light.

Let’s explore the different types of sunrooms available to help you decide which best suits your Bangor, Maine, home.

Traditional Sunroom

A traditional sunroom is an additional room attached to the existing house, often featuring expansive windows and a door separating it from the main house.

This type of home addition allows you to enjoy the beauty of the outdoors while being indoors.

Four-Season Room

These rooms can be used throughout the year, as they include heating and cooling elements.

However, they may be less energy-efficient in colder climates due to insufficient insulation.

  • Year-Round Use: Equipped with HVAC systems for continuous comfort.

  • Energy Considerations: Can be costly to heat and cool in extreme weather.

Three-Season Porch

Ideal for use during spring, summer, and fall, three-season porches typically do not include heating elements, making them unusable during winter.

  • Seasonal Use: Comfortable for three out of four seasons.

  • Cost-Effective: Generally cheaper than four-season rooms due to the lack of HVAC.


Sunrooms with glass walls are perfect for gardening enthusiasts or those who want a panoramic view of the outdoors.

  • Natural Light: Maximizes sunlight exposure.

  • Versatile Use: Great for plants or as a tranquil retreat.

Screened-In Porch

These porches offer the enjoyment of being outdoors without the nuisance of bugs, acting as a three-season room.

  • Outdoor Enjoyment: Provides a bug-free outdoor experience.

  • Timeless Appeal: A classic addition that enhances any home.

Adding a sunroom to your existing space can enhance your living area, provide extra storage, and add value to your home.

Placement Considerations for Sunrooms

Choosing the right spot for your sunroom is essential to maximize its benefits and ensure it complements your existing space.

Here are some key factors to consider when planning the location of your new addition in Bangor, Maine.

Ideal Locations

Sunrooms are typically built off the end of a house, often extending into the backyard.

They can also be positioned on the side of the house that receives the most light.

  • Backyard Extensions: Ideal for creating a seamless transition between indoor and outdoor spaces.

  • Side Additions: Perfect for capturing maximum sunlight and integrating with the existing structure.

Factors to Consider

When deciding where to place your sunroom, consider the following:

  • Climate: Bangor experiences cold winters and mild summers. If you want to use your sunroom year-round, consider a four-season room with proper insulation and heating.

  • Direction:
    • Southern Exposure: Offers more light during winter, keeping your sunroom warmer.
    • Northern Exposure: Stays cooler and is less affected by glare.

  • Surroundings:
    • Trees: Existing trees may provide shade but could also block sunlight. Trimming or removing trees might be necessary.
    • Overhead Structures: Be mindful of nearby buildings or overhangs that could cast shadows on your sunroom.

By carefully selecting the placement of your sunroom, you can ensure it becomes a valuable and enjoyable part of your home.

Pros and Cons of Building a Sunroom

Deciding whether to add a sunroom to your Bangor, Maine, home requires weighing the advantages and drawbacks.

Here are the key pros and cons to help you make an informed decision.


Building a sunroom offers several significant benefits that can enhance your living experience and add value to your home.

  • Cost-Effective: Generally, sunrooms are cheaper to build than full-room additions. This makes them an affordable way to expand your living space without breaking the bank.

  • Natural Light: Sunrooms are designed to let in plenty of natural light, making the space feel open and inviting. This can reduce the need for artificial lighting during the day.

  • Versatile Use: Sunrooms can serve multiple purposes, such as a family room, dining room, or hobby area. Their versatility allows you to use the space in various ways throughout the year.

  • Connection to Outdoors: A sunroom provides a seamless transition between your indoor living space and the outdoor environment, allowing you to enjoy nature from the comfort of your home.

  • Quick Construction: Sunrooms can often be constructed faster than full-room additions, minimizing disruptions to your daily life.


While sunrooms offer many benefits, there are also some downsides to consider.

  • Privacy Issues: Due to their extensive use of glass, sunrooms offer less privacy than traditional rooms. This makes them less suitable for private spaces like bedrooms.

  • Temperature Fluctuations: Sunrooms can experience significant temperature changes, especially if they are not well-insulated. This can make them less comfortable during extreme weather conditions.

  • Limited Use in Cold Climates: In areas like Bangor, where winters can be harsh, a sunroom without proper insulation and heating may be unusable for several months of the year.

  • Not Always Counted as Square Footage: Sunrooms typically aren’t included in a home’s total square footage, which appraisers use to determine property values. This can affect the overall value addition to your house.

  • Higher Maintenance: The extensive glass surfaces in sunrooms require regular cleaning and maintenance to keep them looking their best.

By considering these pros and cons, you can determine whether a sunroom is the right home addition for you.

In the next section, we will explore the pros and cons of building a full-room addition, providing a comprehensive comparison to aid your decision-making process.

Pros and Cons of Building a Full-Room Addition
