modern rustic farmhouse

Stunning, Modern Rustic Farmhouse Perfect for an Executive Sized Lot

This home is unlike any other we’ve ever created. A modern rustic farmhouse designed for the customer that knows exactly what they need from their home. We’ve designed the exterior to be simple yet stately, understated yet elegant. One of the focal points of this design is the attached business center at the left of the home. We’ll talk more about this later in the tour.

The main home provides a living experience unlike any other. The main floor and upper floor work together in concert to make your home your ultimate paradise. You’ll enter the home through the covered patio into the foyer. On your left you’ll see the formal dining room, and on your right, the study. Through the dining room is a butler’s pantry that leads to the kitchen. With one of the largest islands we’ve ever put in a kitchen, this kitchen will satisfy every home cook. You’ll never want for counter or storage space. A charming breakfast nook sits at the end of the island and, on beautiful days, can open up to the covered patio through a set of folding doors. There’s a walk in pantry that’s accessible via both the prep space behind the kitchen and the hallway to the craft room.

On the other side of the main floor is a master suite that would make anyone jealous. A small hallway leads past the master bath to a sizable bedroom that looks out the back of the home. The master bath has an incredible set of features found on very few homes. There’s an entire shower room that also houses the bathtub, giving you a full spa experience in the comfort of your own home. You’ll also get a walk-in closet with clearly defined sides for you and your partner.

The upper floor includes another compliment of incredible rooms. There are two additional bedrooms that both have walk-in closets and en suite bathrooms. There is also a massive vaulted game room that opens up to an upper deck that looks out the rear of the home. The game room connects to a cozy home theater that has a small powder room just outside. The upper floor gives you the ultimate in home entertainment and relaxation.

Back on the main floor to walk through the most distinctive feature of this home, we’ll take a look at the business center. With a totally separate entrance, this provides a supremely professional solution to working from home. You’ll have everything you need to meet with clients and colleagues, from a dedicated bathroom, to a lunch room, to a full sized conference room.

We’ve tried to cover everything, but with a home this size, there’s always going to be more to discover. If you have any questions, please write to us via our contact page. And if you’d like view more of our modern rustic plans, click here.

rustic house plan

Lovely Rustic House Plan

This charming, rustic home is inspired by one of our most popular small designs, “Jupiter.” The floor plan is perfect for anyone that knows exactly what they need from their house. We’ve included all of the necessities and left out all of the fluff to give you the perfect compact home.

You’ll enter through a lovely utility room that is much more comfortable than what you might find in other, similarly sized homes. Further into the home you’ll come to the kitchen, bathroom, and master suite. The kitchen is also the way to the main living area of the home and provides tons of counter space, much more than is usually found in other homes of a similar size. The sink looks out through a window over the porch and gets tons of natural light. The peninsula counter on the other side of the kitchen doubles as both a cozy dining space and an additional prep space. The great room gets a roomy vaulted ceiling, a fireplace, built-ins, and folding door access to the back covered lanai.

One of the things we’ve added to this home is an expanded guest room. With the smaller versions of this plan, this room is best suited for short overnight stays or as a children’s room, but this expanded room gives you a considerable amount more space. The master bedroom is very special, especially when you consider the size of this home. In addition to ample square footage, you’ll also get side by side closets and private access to the back patio. This home’s bathroom is right outside the master, and includes a full size tub/shower combo and linen storage.

Cozy, Skinny Rustic Home

This rustic home captures all of the charm and style of a large farmhouse and presents it in a compact, easy to build package. At just under 800 square feet, it’s a great option for the single person or couple that knows exactly what they need from their home. However, that isn’t to say that it doesn’t have plenty of great, flexible features.

Approaching the home, you’ll see the large bank of windows that look out of the great room. Just to the left is the entry, which puts you right in the great room. Once inside the home, you’ll get a real sense for how much bigger this home lives than the square footage would make you think. With a vaulted ceiling, adjoining dining room, fireplace, and folding door access to the outdoor living space, it’ll feel like you’re in a much larger home. Just off of the great room is a lovely den, something not often found in homes of this size.

The kitchen is fully featured and includes an island/bar for more informal dining. Tons of counter space, thoughtful appliance placement, and natural light make this kitchen a surefire winner. A full bathroom lies just beyond the kitchen, and even includes hookups for stackable appliances. Just past the bathroom is the vaulted bedroom. This is a really special bedroom; you’ll get a fireplace, a vaulted ceiling, a walk-in closet, and last but not least, separate access to the covered outdoor space. Rounding out the floor plan is a large outdoor storage closet, perfect for landscaping equipment, outdoor furniture, or anything else you might need a little extra space for.

Farmhouse Studio

Farmhouse Studio with Garage

We’ve taken all of the appeal and charm of the classic farmhouse and distilled it down into a studio plan that will fit on tons of lots. With this plan you get a compact yet flexible design that affords you either an additional rental on your property, a primary residence (with the addition of a kitchen), an art studio, a gym, or anything else you can imagine.

A large two car garage with extra depth adds room for a project area or extra storage, and a staircase to the right of the garage will take you up to the studio/loft. Here is where you can really let your imagination run wild. There is a very sizable storage closet just near the main door, as well as a full bathroom and room to build out a kitchen if you’d like.

The sky is the limit with this compact design! If you have any questions or would like to make modifications to this home, reach out via our contact page here.

Two Story Farm House
MF-2968-JLH

Bright and Elegant Two Story Farm Plan

Everything about this house plan screams rustic charm with a modern flair. If you’re looking for a two story farm style plan, it’s hard to beat this one.

Looking at the main floor plan, the first thing you notice might be just how open and airy this home is. Walking through the foyer, you’ll first see the large, vaulted casita on your right. Our signature casita designs include small, attached, but self-contained apartments. These spaces are perfect for just about anything: home offices, guest suites, creative studios, rental rooms, you name it. They include bathrooms, and this one even includes a small kitchenette. The sky is the limit with what you use your casita for.

Further into the home, you’ll come to the central living core, where the kitchen, living room, and dining room all converge into an open and inviting living space. Whether you are entertaining, having a family dinner, or just relaxing in the evening, this arrangement promotes easy living and comfort. Out back, you’ll have a covered living space that even has fixtures for easy outdoor cooking. Open up the sliding door and connect the indoors to the outdoors for the ultimate summertime cookout.

The master suite rounds out the main floor and is really something special. It gets its own private covered patio, accessed via a sliding door at the back of the bedroom. The master bathroom gets the deluxe treatment, with a separate tub and shower, his and hers sinks, and a huge walk-in closet.

On the upper floor, you’ll find two additional full bedroom suites, each with their own attached bathroom and walk-in closet. In the center is a spacious loft that you could easily use an smaller upstairs sitting or play area. The loft looks out over living room to the striking window bank at the back of the home.

Multi Suite
M-1828-676

Multi Suite Home with Tons of Options

We’ve got another ultra flexible multi suite option for those that need equal space for all residents. The main house has five bedrooms, and the lower floor ADU has two; each of the bedrooms comes with a full bathroom, so that everyone has everything they need within arms reach.

Starting with the main home, you’ll enter through the front and immediately notice the first bedroom suite on your left, the garage on your right, and the stairs straight ahead. Upstairs you will find a luxurious, semi-open, living room/kitchen/dining room. We’ve arranged them in an L-shape so that you can still have a semi-private dining room separate from the main living space. The kitchen is between the two so that you can still have easy access when entertaining or just visiting or working around the kitchen island. Also on the second floor are two more sizable bedrooms, each with en suite bathrooms, both with tubs. On the upper floor we’ve included another two large bedroom suites as well as a laundry closet at the top landing. Each of these bedrooms gets plenty of natural light through the back of the home.

Moving to the lower floor ADU, you’ll find the private entrance on the left side of the home that leads right into the open kitchen/great room. The kitchen is a conservative L-shape, with a good sized island right in the middle. The ADU also includes two generously sized bedrooms, again each with their own full en suite bathrooms. At the corner of the great room you’ll see the ADU also gets its own laundry hookups. Rounding out the lower floor of the home is a one car garage with access from the foyer and the right side of the property.

We can make modifications to any of our house plans, so feel free to write to us at our contact page.

Incredible Multi Suite House Plan

As our world changes and the need for functional, more efficient space grows, we are trying to lead the charge by offering a range of deluxe, multi suite house plans. This home features seven complete full suites, five in the main home and two in the lower floor ADU. The idea with this home is for everyone to be able to have plenty of privacy and have everything they need within reach.

When you enter the bottom floor through the front of the home, you’ll immediately head up the stairs to the main home. The main portion of the house constitutes the top two floors while the ADU is all on the bottom floor. When you arrive on the main floor you’ll land in the open, spacious central dining/living room, flanked at the front by the kitchen and two large suites, both with vaulted ceilings. Right next to the dining room is the third and final suite on the main floor. The stairs to the upper floor are right between the two front bedrooms.

Upstairs are two almost equally sized vaulted bedrooms suites, as well as the utility closet. Downstairs is a totally independent ADU, accessed via an entrance around the left side of the home. When you enter, the first thing you’ll see is the spacious dining/living room, arranged with the kitchen similarly to the upper floor. The kitchen includes counter seating and plenty of prep space thanks to the U-shaped layout. Two full  bedroom suites are behind the main living space. Last but not least is the garage underneath the home, with enough room for one car and some additional storage at the rear.

skinny house
M-2251-895

A Skinny House Plan with a Fully Featured ADU

This is a great example of how to get big living in a skinny house plan. This home is less than 15 feet wide but packs in tons of bedrooms, living space, and even a deluxe ADU. The main house has 5 bedrooms, each with their own full, en suite bath(!). This gives you functionally 5 master suites. The bedrooms are sized roughly the same, with the added bonus of the upstairs bedrooms being vaulted. The main floor is a long, open concept kitchen/living room layout with a fireplace and windows all along the length of the home to let in plenty of light. The utility room is on the upper floor between the two bedrooms. The ADU opens up a world of possibilities. You can house long term guests, renters, or even extended family in this fabulous home. An incredibly flexible space, the ADU boasts two floors of living coming in at just about 900 square feet. The entrance is completely separate from the main home, a huge bonus if you decide to rent it out. The main floor includes a lovely and carefully placed kitchen, as well as a sizable living room and a bedroom with a full bath and walk in closet. Upstairs you’ll find two additional bedrooms, also with their own full en suite bathrooms. We can make modifications to any of our homes, and welcome any questions you may have.

One Story Modern Farmhouse Sized Just Right

Few things conjure up a sense of nostalgia quite like a farmhouse. Their rustic, understated country looks calm the spirit and remind us of a simpler time. This one story modern farmhouse is perfect for those that desire an open, comfortable floor plan while still being able to keep their sanity.

Before you even enter the home, the first thing you’ll notice is an additional front door to the left. This door actually leads to one of our signature Casitas; small, standalone apartments that can be used for extended stay guests, older children, or even as creative studios. It includes a full bath, walk-in closet, and private entrance.

Moving into the main home, you’ll enter through an inviting foyer with a 12′ ceiling. You’ll quickly be swept into the main living space, where an open concept kitchen/dining room/great room layout forms the core of the home. Both the great room and dining room have vaulted ceilings, making them feel breezy and open. The kitchen is arranged in an easy-working L-shape and includes tons of counter space. A walk-in pantry in the corner completes this gourmet kitchen.

The bedrooms in this home are situated each in their own private corner, with the master bedroom on the left side of the home while the two additional bedrooms are on the right side. These bedrooms are comparably sized, and share a full bath between them. The master suite has everything you can want, including a vaulted ceiling, private patio access, and a bathroom complete with separate tub and shower, his and hers sinks, and a generous walk-in closet.

Rounding out this one story modern farmhouse is the utility room just off the master suite (making laundry a snap), and a three car garage with access via the foyer.

modern barn
MB-5135

The Ultimate Modern Barn Home

This may be the modern barn to end all barns homes. From first glance, you’ll quickly notice that this home is rustic yet grand, charming yet palatial. The traditional, farm-inspired exterior gives way to a floor plan that includes seven(!) bedrooms, six bathrooms, a deluxe basement, and many, many more exciting features.

Entering the home through the foyer, you’ll find the regal, vaulted great room before you, which offers ample built-in storage, a fireplace, and the perfect space to relax or entertain. Immediately surrounding the great room are the kitchen, dining room, breakfast nook, and hallways on either side to escort you to the master, den, and additional bedrooms.

This home’s kitchen includes an oversized island and an L-shaped layout to allow for ease of use by multiple occupants. It’s hard to imagine wanting more counter space in this kitchen. A cozy breakfast nook is tucked just off the kitchen and looks out over the back porch, making it a charming space for a casual meal.

Also on this side of the home are two generously sized bedrooms along with a full bath, pantry, and the beautiful utility room. Moving right of the foyer will take you past the den and the staircase to the lower floor (which we will explore a bit later) to the lavish master suite.

Immediately upon entering the master bedroom you will be struck by the vaulted ceiling, the amount of space and light, and the amazing master bath. These kinds of master suites are hard to find in many other modern barn house plans. The bathroom offers you his and hers sinks, two separate walk-in closets, a custom shower, and a private toilet. Absolutely not to be missed in the master bedroom is the access to the back deck and the hot tub.

The basement of this modern barn home is stunning, and makes the perfect place to wind down after a long day, hang out with the family, or entertain. A large rec room with full bar forms the nucleus of the basement, while two bedrooms on either side, each with a full bath, and access to the lower floor of the back patio complete the lower floor.

Last but certainly not least is the complete one bedroom apartment above the garage. This space could easily be used as living quarters for a long term guest, an Airbnb rental, or a creative space. It comes with a full kitchen, a comfortable bedroom, a full bath, and a large living space.
