How Much Money Is a Home Extension Going to Cost You? A Breakdown Of The Project Costs

So, you want to make an extension to your home. What will it cost you? Well, you should know that your final home addition costs can vary by a substantial amount according to where you live, and some areas have higher construction and material costs as well as increased contractor and labor costs. Whether your home is located in the north, south, east, or west will determine your final project expenses and total costs involved.

You will find plans for home additions that are suited for one of these specific regions as well as plans that can fit almost anywhere in the country. Some regions of the country have certain styles, and these designs can also affect any project costs. One reason why material costs can vary by a large amount is the transportation involved. If you choose materials that are not found locally these must be transported in, and this can increase your material costs significantly. 

Average Home Addition Costs per Square Footage and Area

A budget project will include costs for home additions that are economical and do not involve top dollar materials, appliances, or fixtures. These projects will supply a finished addition area but little else. A mid level addition can include higher home addition costs, but you will get better materials and appliances in many cases in exchange for a higher price. This choice is somewhere between the basic and the custom options, and can be more affordable than having a custom addition built usually.

A custom addition is the most expensive choice but also gives you exactly what you are looking for. These additions can cost one hundred thousand dollars or more, and with this option you can choose every aspect of your new space according to what you want. With a custom addition one of the costs of home additions is the expense of having custom plans created by an architect. This step alone can cost thousands of dollars, and using plans that can be purchased for a lot less online can really help lower your project costs.

Home Addition Costs and the Available Options

The cost of home additions will depend on what available options you are interested in, and the type of addition you are looking for. Your options can include:

  • Another Bathroom- A bathroom addition will normally average around ten thousand dollars for a middle of the road project. If you want a deluxe bathroom with all the perks you could spend fifty thousand dollars or more. 
  • An Extra Bedroom- An extra bedroom can cost you between eight thousand and twenty thousand dollars for a budget or mid level addition, but this will depend on the other factors as well. A top of the line option could cost in excess of thirty or forty thousand dollars.
  • A Deck- A deck can be a great way to add living space while keeping home addition costs down.

    It’s strange to me that someone would pay to build another bedroom. I mean…that seems very expensive just to get an extra sleeping space. But then, people do crazy things.

    Yes, and for that matter, to add another bathroom? So weird. I did like the article, though. But I didn’t realize that some people actually pay over $50,000 to add something so minor as a bedroom or a bathroom. I mean…just sell your house and buy another one?
