Before adding a sunroom to your home, you will want to estimate the costs first. While a sunroom might look pricey, one of these additions will typically cost less than a den or family room. Plus, a sunroom pays back up to 70 percent of its building costs due to increased resale value, while adding charm and extra space. Before estimating the costs of building your new room, here are a few things to keep in mind.
The size of the sunroom will have the most impact on the cost of your building project. As larger sunrooms require more wood and glass to build them, the cost rises proportionately with the necessary building materials. A high ceiling will also increase the cost of the room. An 8x10 prefabricated space will cost between $15,000-$35,000, which includes the preparation and foundation work. However, larger models, or ones that include various additions like remote-controlled blinds can cost upward of $70,000.
Doing It Yourself
If you complete the labor yourself, your sunroom will be less expensive than if you hire someone else to do it. For the cheapest two-season model, you can purchase a do-it-yourself kit for about $1,000. One of these models will include everything you need, including glass windowpanes and insect screens, but this model will not be all-weather proof.
Hiring a Professional
Instead of doing it yourself, you could hire professionals to do the work. These professional’s costs vary and also depend on which materials they decide to use. For example, hiring a carpenter costs approximately $70 per hour, but this price does not include the cost of the materials he chooses.
Also keep in mind that you will need to install wiring and lighting to code, and an electrician’s labor will cost you about $70 per hour. However, if you are unfamiliar with this type of work, it’s best to pay more and hire a professional. Wrongly wiring electricity can shock you or put your family in danger.
If you already have a raised porch or deck, this will lower the cost of construction of your sunroom. If not, you must budget for laying a foundation and raising a deck, first. Laying the foundation will cost about $2,000-4,000. The floor will also add to the costs of the raised deck.
Your sunroom cost estimates will be different depending on the type of materials you choose to build with. While a wooden frame would cost the most, a vinyl frame would cost the least. An aluminum frame costs somewhere in-between. Use a material that suits both your needs and budget, and remember that an economical sunroom can still look posh if it's decorated properly.
The number of seasons in which you want to use your additional room will also help you calculate your expenditures. A two-season sunroom is the least expensive, while a four-seasons sunroom with heating and cooling systems are the most costly. One of the latter 8x10 rooms with all of the perks will cost upward of $70,000.
Apart from these costs, you also have to factor in the cost of obtaining planning permission as well. This will typically cost you about $400. Make sure you obtain local planning permission before you start adding your sunroom, and remember that the permission could take 6-8 weeks to be granted.
Depending on how large you want your sunroom, what materials you want to make it with, and whether you hire a professional or you do it yourself, your total budget estimate will vary widely. However, building this additional space will likely cost at least $10,000 and upward of $70,000.
In addition, you should remember that after you build the room, you will have to decorate it.
