Are the children getting older and feel they need their own room? Is your aging parent coming to live with you? Did you just move your child into what was once the guest room and now need another room for occasional guests? If you answered yes to any of these questions, you may be ready to extend your present home with a room addition.

Is there room in your attic to add a bedroom? Photo by Carrie Qualters

Before you jump right in and begin tearing out walls, there are a few things you need to consider.

1. Do you have space in your house that is rarely used that you can convert into a bedroom?

2. Can you convert part or all of your attic or basement into a bedroom?

3. Can you build upwards to create additional space?

A yes answer to any of these questions could save you considerable money. Some other things to consider:

4. Will your home remain inside your property lines if you add onto the side or back?

5. If you add a onto your house, how will you enter and exit that room?

6. Will the new room affect the structure of your home?

7. How will it be connected to the existing roofing?

8. Are you willing to give up yard space for the addition?

9. How will the addition affect the appearance of your present structure?

Once you have chosen the perfect location for your room, you will need to consider how this structure will affect the neighborhood. Will the new structure match your existing exterior siding and roof line?  You do not want your home to stand out as an eyesore to the neighbors.

There are a few things you can do to ensure a bedroom addition will work with the rest of your house.

Plan on using materials that blend well with the existing roofing and exterior wall materials, and the existing windows. Inquire about how the foundation will be placed and if there will be space beneath the new room. If so, how will you use the new space?


After considering the exterior, you must next consider how an addition will affect the interior of your home. Will it require the removal of walls? How will you provide access to the room? How will it affect the other rooms in the home? Will you extend a hallway or add a hallway? Will it be accessed through an existing room?

The next step is to design your new bedroom. How big will your room be? Will it have a closet? Will it be a walk-in closet? Where will the closet be? Will it have a window? How large will the window be? You should also decide what type of flooring it will have, carpet, tile, or wood. What type of lighting will be used and what kind of fixtures will be needed?

After designing the bedroom, you can think about who will do the work. Will you do the work yourself or hire a contractor or architect? Then check on building permits.  Determine how much of the work will need to be performed by state-licensed workers, such as electrical work and plumbing. Plan for the construction of the foundation. Once you begin scheduling the work of framing, plumbing, electrical, flooring, and drywall, you can begin imagining the completed project and adding the finishing touches.
