Additions Modular Floor Plans

Modular addition plans come in two types – attached modular home addition plans and second-story modular house addition plans.

Unfortunately, we’re not building second-story additions at this time.  These projects take a lot of extra money and time with design, engineering, and construction labor.  Your current home will most likely require structural work to carry the weight of the second story.  More importantly, it will almost certainly need extensive remodeling to make your first floor plan work.

Some customers decide to tear down their current home and replace it with a new two-story once they discover that the cost is often the same as adding a second-story addition.  Other customers, when they have room on their property, build an attached addition.  Still other customers sell their current home and purchase a building lot for a new home.  If a brand-new home or an attached addition interests you, please let us know and we’ll be happy to discuss this possibility with you.

Our attached modular additions come in multiple lengths and widths. They can be designed with a traditional or contemporary flair. In addition, our prefab addition plans can have any number of bedrooms and baths. Best of all, modular construction is a great way to build an addition. You get the quality and price advantage that modular homes are known for, along with faster build time. Speed is particularly beneficial when building precision built homes, since the construction will temporarily disrupt your family’s life, especially if you remain in your home while the work is being done

Our attached modular home addition plans place the addition to the side of a home to create either a separate living unit, such as an in-law apartment, or additional rooms, such as a new kitchen, dining room, and great room. Some of our customers design in-law addition plans at the same time that they build a new modular home with us. Our three Harmony plans  (Harmony 1, Harmony 2, and Harmony 3) are very popular with those looking for in-law additions. Our selection of attached addition plans is substantial, since you can use any of our single family and multifamily plans. However, if you will be placing your modular home addition next to an existing house, you might prefer for us to help you design one of our custom home plans.

If you seek Elder Cottage Housing Opportunity addition plans, often known as ECHO in-law addition plans, you will want to use our attached additions. ECHO modular addition plans are no different from any other in-law additions. See Building a Modular Addition.

You can change any of our plans in small and big ways to make them look as if they were always part of your  home. You can adjust the roof pitch of your prefab addition plans to fit in with your existing house, and you can dress up the exterior features of your modular additions with matching siding and fancy moldings.

Finally, you can also change the exterior or interior appearance of any of our plans for additions by changing the size, location, or quantity of any of the following:

  • Laundry room
  • Master bath suite
  • Garage
  • Porch
  • Walk-in closet
  • Pantry closet
  • Extra storage space
  • Larger rooms or more open floor plan
  • Taller ceilings – tray, cathedral, and vault
  • Fireplaces
  • Walk-out bays
  • Windows – circle tops, transoms, and palladium
  • Kitchen cabinets
  • Working island bar with raised breakfast counter
  • Dual bath vanities
  • Whirlpool bath
  • Roof pitch
  • Dormers
  • Decorative exterior window and door moldings
  • Wet bar
  • French doors
  • Skylights
  • Built-in bookshelves or entertainment center
  • U-shaped stairs
