Addition Modular Floor Plans

Our modular addition plans come in two types – attached modular home addition plans and second-story modular house addition plans. Both types come in multiple lengths and widths. Also, both types can be designed with a traditional or contemporary flair. In addition, both types of prefab addition plans can have any number of bedrooms and baths. Best of all, modular construction is a great way to build either type of 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.

Our second-story modular home addition plans place the modules on top of an existing one-story home to make it into a two-story house. The speed of modular construction is a tremendous benefit when building a modular second-story, since the addition can be set in place within hours after the roof is removed from your existing home. If you need second-story additions, we recommend that you use the second floor layouts of our two-story plans that are similar in size to your existing home. For example, you can use the second floor of our Whately 1 two-story plan if you want to create a three bedroom plan with a vaulted foyer over a one-story that is 28′ x 44′. Keep in mind that you will likely need our help to customize your second-story addition plans to match your existing home.

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:

* Study, office, or computer room
*   First floor master bedroom
*   Media or hobby room
*   Bonus room over a family room or garage
*   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

The Home Store was very helpful. They detailed what I was getting and then itemized the prices. They gave me a detailed list of the tasks I’d need to do to complete the contracting work, something very few companies do. Also, they did a good job correcting a couple of warranty items. I’d definitely buy a home again from them.read more

We are nearing completion of our new home on Cape Cod. The Home Store has provided excellent service from helping to modify the layout of our open space modular home (including my dream kitchen) to drop setting the modular sections on the foundation. A snafu was encountered, through no fault of The Home Store, when the original manufacturer, Excel, went bankrupt, just before the manufacture of our home was to start. The Home Store stepped up and demonstrated their strong customer service by finding a new manufacturer who could construct our original design with only a short delay and by paying to correct errors by the new manufacturer. I recommend The Home Store highly!!read more

What an incredible first time experience with The Home Store. As a Development Company, we had decided to try to replace an existing home, that was in much needed repair with a modular home. The Home Store's staff, particularly Dave Lewis were all OUTSTANDING! The process was totally turn key and simple. All changes that we wanted to make to the house was accommodated. The finished product was of high quality and more importantly delivered on time. Modular homes have come so far that they are hard to tell the difference from a home built on site. I would also add that the quality is all as good as a custom home without any headaches trying to find sub contractors to complete the process.You owe it to yourself to check out The Home Store if you are thinking of building a new home. PS: Check out The Home Store blog and you can see the finished product of the home we purchased, The Wiltshire T-Cape Home. Thanks again to everybody's effort at The Home Store!read more

I have seen some of the homes being sold by The Home Store and can say I am proud to be a partner with them. The efforts in detail by The Home Store that go into the sale, design, manufacturing and completion are unmatched in this industry. Patrick and Dave are very professional sales people with the knowledge you need to design the true Custom Modular Home.read more

Right off the bat. Was told we could not afford the home, and this was based on a phone call. Not impressed by this company.read more
