7 Keys to Estimating Your Sunroom Cost

by Kevin Smith Author

Adding a sunroom can lend your home an amazing new dimension. You'll get a healthy dose of outdoor sunlight without having to sacrifice the comfort of being indoors. But how much will the sunroom cost? Here are a few things to consider:

1. Sunrooms Can Vary Greatly in Cost

Sunrooms can cost anywhere from $10,000 to $80,000. That's obviously a big range, and that's because there are a lot of variables that need to be taken into account when you're building a sunroom. A general estimate is that the average sunroom will be between $15,000 and $25,000. Still, this amount will change, as the type of material you use, the size of the room itself, and the cost of labor will all be significant considerations.

2. The Size of the Sunroom Is Important

It's probably not terribly surprising: the bigger the room, the more it will typically cost. If your new sunroom is going to be insulated, the price tag usually runs about $300 per square foot. If you already know the size of the project, this can give you a little bit of an idea... but there are other factors that play a part as well.

3. Your Materials Matter

How sturdy do you want the sunroom to be? What are you building it out of? Are you using high-quality glass that provides good insulation? Materials can range from just $2 per square foot to $35, depending on what type you choose. One key thing to consider: poor-quality windows can lose heat like crazy, so it's a good idea to invest in some energy-efficient windows. It may cost a bit more upfront, but you'll save money in the long run.

4. There Are Different Types of Sunroom

You may have already bumped into a pair of terms: the four-season room (or "life room"), and the three-season room. The four-season room is a comfortable, temperature-controlled environment that you can enjoy any time of year. It typically has added insulation, heating, and air conditioning. A three-season room is not temperature-controlled, which makes it a less costly choice. Of course, if you live in an area with extreme weather, you may not be able to use a three-season room during the coldest or hottest months.

5. Don't Forget About Permit Costs

Some types of sunrooms will require a permit so that they conform to local building code. Typically these permits are under $300, but you should check to make sure––preferably before you start building. If you live in a state with property taxes, you may want to see if the addition will affect these, too.

6. The Cost of Labor Is Potentially the Biggest Expense

Most sunrooms require the expertise of carpenters, as well as electricians, painters, and window installers. You may even need to hire plumbers if you plan on having running water in the unit. Unless you're doing all the construction yourself, odds are you'll need some skilled help somewhere along the line.

7. Sunroom Kits Are Also an Option

Sunroom kits are a low-cost alternative to a full construction project. These pre-made kits can be customized to the dimensions you need, and shipped to your home. They obviously require a little more effort, but if you're the kind of person who loves putting together a DIY table or cabinet, this money-saving option may be the project for you (and one or two friends).

The choice is yours: you go all-out and splurge on a luxury, or you can go for something more practical. Either way, the sunroom is a serene and beautiful addition to any home.
