My husband just added a bedroom onto our house. It cost about $5,000 and didn't include a bathroom. He did all the work, so there was no labor cost. Remember that most contractors will add 1/3 material cost for labor. So if you go with a basic room plus bathroom, that's going to be a minimum of around $10.000 in materials.
Suite Addition. Building out to add a bedroom allows you maximum flexibility. Adding a 14-by-16-foot master suite, including bathroom, over a crawlspace costs an average of $103,844 as of 2014, according to Remodeling. This type of project also offers a nearly 75 percent return on investment.
House bump outs offer a tantalizing solution to that age-old conflict of space and money: you want more space in your house, but it costs more money than you can afford. When you want multi-room space—bedroom, bathroom, and living room or office, for instance—you build a full-blown addition.
If you have more bedrooms than bathrooms in your home, adding a bathroom will increase your home's value by a larger percentage. The homebuilders' study found that in a home with one bathroom, adding a half bathroom increased the home's value by 11.5 percent for a two-bedroom home, 12 percent for a three-bedroom home and 12.5 percent for a four-bedroom home.
If that is the case, the cost to add a bathroom in your home will be closer to $15,000, for a basic bathroom. If you add custom features or expensive upgrades, your bathroom addition cost could easily excel to $25,000.
