Atrium cost

This is an indoor space with a glass roof. Atrium walls are usually pre-built, so the cost only includes the construction of the glass ceiling. The average price of this addition largely depends on the extent of the roof work required, but expect to pay $6,000 to $30,000.

Solarium cost

This is an enclosed space attached to your house made entirely of glass. While it doesn't have any insulation or climate control, it can serve as a perfect area for plants to grow all year. Costs for this sunroom varies, ranging from $30,000 to $90,000.

Prefab sunroom cost

Prefabricated sunrooms are usually less expensive than other types. Most are aluminum or vinyl, and they often arrive at your home ready to be assembled. Expect to pay $5,000 to $40,000.

Four-season sunroom cost

True to its name, this variant is perfect for all seasons because it is insulated and can have its own thermostat and electrical wiring. It is the closest to a full-fledged house extension. This luxurious sunroom addition can cost around $23,000 to $85,000.

Three-season sunroom cost

A less insulated version of a four-season sunroom, this can be a pleasant place to lounge in, except during winter and scorching summer days. This type of sunroom usually doesn’t have insulation, electricity, and HVAC controls. Because of this, it’s typically less expensive than a four-season sunroom, costing $10,000 to $50,000.

Conservatory cost

Like a solarium, this is an all-glass enclosure. The only difference is that it has proper insulation and electricity and is temperature-controlled. A conservatory can cost $50,000 to $150,000.

What other factors affect the cost of adding a sunroom?

Before starting your project, you need to consider many things, such as the following:

Your area of residence

High-demand cities can be more expensive than rural locations with lower labor rates. See the price list by state below:







New York










North Carolina


New Mexico




South Dakota


Sunroom location

Do you have an existing patio or deck where you can place your sunroom? This can cost less because there’s no need to pay extra to stabilize the construction. But you might need someone to repair or upgrade your patio or deck to accommodate the sunroom and the people who will be enjoying it. You also need to consider the expense of constructing a concrete slab.

If you don’t have an existing foundation, clear the land first. This involves demolishing old constructions, removing trees, and excavating the land.

Sunroom size

The bigger the sunroom is, the higher the cost to build it. Here’s the average price of sunroom additions by feet:

Sunroom size (in feet)



$4,000 - $6,000


$5,000 - $8,000

Energy efficiency

Insulation is essential if you’d like to have a four-season sunroom or conservatory. Many high-tech, energy-saving products are available, but their costs rise as they get sophisticated. Electrical wirings, outlets, HVAC units, and other insulation needs can increase your expenses from $1,500 to $6,000 per room.

Roofing, flooring, and interior design

Roofing costs about $8,500 on average, depending on the sunroom you want to have. A glass-encased roof with a steel framework is necessary for atriums, solariums, and conservatories. Other sunroom types need asphalt shingles, which cost around $3,600. On top of that, elaborate millwork and flooring can increase the price. 

Interior design and decor can influence the total cost of your sunroom. Hire the right person to build and assemble furniture for your sunroom. Feel free to spend more time completing and finishing the space after it's finished!


Homeowners in the USA often pay $4,500 to $17,500 on labor, depending on the sunroom type.

Building permit costs

Like most large home renovation projects, building a sunroom involves securing a permit. The number of permits you'll need depends on where you reside. Generally, homeowners pay between $350 and $1,225 for a new sunroom. 

Research your local building codes for information on what permissions you'll need. Your Tasker can also help you identify which permits you'll need and secure them. Suppose you build a sunroom without government approval. In that case, your insurance company might refuse to pay a claim if something goes wrong. You'll have trouble selling the house in the future. Permission usually takes four to eight weeks after application submission.

Typically, there is no minimum space required to build a sunroom. You can have a sunroom that suits your needs, from small atriums to huge family conservatories.

Expect to wait up to 12 weeks. This timeframe typically involves design consultation, site preparation, material selection, and final sunroom construction. It also depends on the style and amenities you choose during the initial design stages.

A properly constructed sunroom can last for 10 to 50 years and even longer, as long as you maintain it well. You can also upgrade your sunroom and improve its glazing, roofing, or rendering. Your sunroom can last for decades, but upgrading it can make it seem brand-new!
