Second-Story Additions

Second Story Additions in Dekalb IL

Second-story additions are a great way to expand the living space in your current home. Depending on the situation, building up can sometimes be less expensive per square foot than building out because there won't be any need for foundation building. With a second-floor addition, you can add bedrooms, bathrooms, an office/study, or any other space you desire.


Building a second-story addition onto your current home can allow you to:

  • Create additional living space without having to move. This means you can stay in your beloved neighborhood and avoid uprooting your children from their current schools or increasing your daily commute.
  • Increase the value of your home. By adding more bedrooms, bathrooms, and other spaces in your second-story addition, you will be able to increase your home's value. If you have resale in mind, two-story addition is a great investment.
  • Keep your outdoor living space as is. Since you're not building out, you don't have to worry about reducing the size of your yard or removing existing outdoor spaces like patios, decks, or outdoor kitchens.
  • Design the layout and features of every room.
  • Build a space to suit your needs and design preferences. With a second-story addition, you can tailor the new space to your lifestyle and add your own personality to the design. Do you want a tranquil farmhouse feel or a sleek contemporary look? It's all up to you!

If a full second-story addition is a little more than what you need, consider a dormer addition. A dormer is an addition that comes through the roof to create a higher ceiling and more interior space. This will require removing part of the roof and building the new structure into the space. You can use the dormer addition to create a private office, bedroom, or playroom.

Family Room and Game Room Additions

Every home needs to have a family room or game room! It's the perfect space in your home to gather with friends and family, enjoy video and board games, and watch movies. If you're thinking about building a family room or game room addition in your Fox Valley home, you'll want to consider features like a:

  • Wide-Screen Television or Projector
  • Built-In Surround Sound System
  • Fireplace
  • Wet Bar with Built-In Wine Cooler

Bathroom Additions

You want to stop sharing a bathroom with your children, and who could blame you? So what's the best solution? Creating a tranquil master bathroom for you to unwind after a long day at work. Don't have enough bathrooms to suit your family and guests? Consider building a new bathroom on the main level of your home to accommodate the whole family. A bathroom addition will not only give you the space that you need but will also help to increase the value of your home. If you're looking to create a new master or guest bath, some of the things you'll want to consider include:

  • Style: Which style do you like best? Contemporary, Farmhouse, Traditional, Modern, Transitional?
  • Layout: Where do you want your vanity, shower, and toilet to be located?
  • Storage Needs: Features like his and her vanities offer lots of storage space.
  • Material Options for Your Countertop, Cabinets, and Backsplash: Do you want Quartz countertops with an oak wood vanity and a glass tile backsplash?
  • Flooring: What kind of flooring do you want? Wood, ceramic tile, vinyl, or concrete?
  • Lighting: Do you want sconces, pendant lights, or recessed lighting in your new bathroom?
  • Luxury Features: Add some luxury with a freestanding tub or walk-in shower.
  • Universal Design Elements: Grab bars, non-slip flooring, and barrier-free showers are all options you should consider for aging in place

Kitchen Additions

Kitchen Remodel Contractor With White Tile Backsplash

Create an incredible in-law suite or basement apartment with a kitchen addition. This will allow your in-laws, guests, or tenants to have a space to cook without having to enter the main level of the home. This is especially convenient for aging loved ones that may have trouble making their way upstairs. While a kitchen addition is generally smaller than the main level kitchen, it should have a:

  • Sink
  • Oven
  • Dishwasher
  • Microwave
  • Custom Cabinets for Storage

A kitchen addition can increase the value of your home and make it more convenient for your loved ones and guests. If you're renting out your home's basement apartment, a kitchen addition will allow you to increase the monthly rent which you could use to make even more improvements to your Fox Valley home.

Bedroom Additions and In-Law Suites

Beautiful Master Bedroom Remodel With Large Windows

If your family is expanding, a bedroom addition or in-law suite might be your best option. Avoid the stress of having to move into a larger home by building an addition like this one. Building a bedroom or in-law suite will increase both the size of your home and its value. You can use your bedroom addition as:

  • A nursery for your new arrival
  • A spacious master suite
  • An in-law suite to provide your aging loved ones with more privacy
  • A lively children's room
  • The perfect guest retreat

If you want to build a bedroom addition, you'll want to think about what features are most important to you. Incorporating features like a walk-in closet, fireplace, or custom storage may increase your cost, but are well worth the investment in the long run.
