Sample Floor Plans

If the client chooses, Marr Development will purchase and work with any home plan that suits the needs of the homebuyer, however, our preferred online vendor is eplans.  

Below are six popular example homes and links to their full details.  

Sample Floor Plans

Choosing a home plan is one of the more exciting events in one’s life and we are here to make that experience one-of-a-kind.  We do not have a standard set of ‘cookie cutter’ plans to choose from, so you don’t have to settle on something someone else chose for you…after all this is your dream home!  We’ll build exactly what you want!

Unlike most traditional home builders who use subcontractors for each different trade, we are an all-inclusive design/build company.  The designer and contractors are all on the same team, as are all trades.  Marr Development has each individual trade in-house and we do not subcontract to anyone.  

We have an in-house architect and drafting professionals who can sit down with any client and design a home based on your specifications. Or if you prefer, we can purchase and customize home plans from any source. There are literally thousands of home plans out there ready to be customized to your preferences. In most cases, viewing plans online helps home buyers better visualize their ideas and see examples of layouts they like, and create a list of must-haves.

Country Style Home
1887 sq feet

A wraparound deck on this country home invites outdoor living. Inside, spacious common areas include the open, fireplace-warmed living room and a breakfast area, flowing directly into the island kitchen. All three bedrooms reside upstairs, with the master suite enjoying a private full bathroom and walk-in closet. A bonus room allows for future expansion or additional storage space.

Farmhouse Traditional Country
2214 sq feet

It's all about relaxing on the porch with this lovely modern farmhouse. But which porch? That's the question, since you've got a huge wraparound porch that goes all the way from the front to both sides, and then a terrace/barbecue porch in back with a chic fireplace for outdoor fun.

Traditional Style Home
2217 sq feet

This traditional home features several gable peaks and a triplet of columns to create a stunning facade. The interior layout positions rooms for ultimate privacy and convenience. A vaulted ceiling and fireplace accent the great room that also overlooks the kitchen and rear porch. The kitchen’s angled serving bar serves as a divider between the kitchen and great room. Tucked away in the rear of the home is the master suite. Two walk-in closets and an elegant master bath makeup the suite.

Farmhouse Traditional Country
2553 sq feet

With its versatile bonus room and a home office, this 2,553-square-foot home nicely accommodates changing needs over time. The open layout of the great room, dining area, and island kitchen make it easy for parents to keep an eye on kids, or for holiday hosts to mingle with guests without letting the hors d’oeurvres burn. Owners will appreciate the impressive master suite and its private bathroom.

Traditional Style Home
2687 sq feet

Stone and siding accent this beautiful country cottage, a perfect example of an idyllic family home. Inside, the two-story foyer leads to the family room, soaring with a two-story vaulted ceiling. Here, a lateral fireplace allows expansive views of the rear property through a wall of windows. An open kitchen serves the bayed breakfast nook and dining room with ease. To the right, a bedroom/home office is convenient to the full bath. To the far left, the master suite is a relaxing getaway, complete with a vaulted bath and a tub set in a radius window. Two generous bedrooms upstairs share a full bath and bonus space.

Classic Style Home
3312 sq feet

With its grand elevation and flexible layout, this plan beautifully blends old and new traditions. On the main floor, a guest suite with a private bathroom gives privacy to visitors or a live-in relative. In the open kitchen, an island adds counter space and the walk-in pantry offers generous storage that's easy to reach on the way in from the garage. Upstairs, the master suite invites you to enjoy the view from the window seat in the sitting room or hang out in the luxurious bathroom (check out that shower!). Other highlights of the suite include a huge walk-in closet and a decorative tray ceiling in the generous bedroom.
