Modern Farmhouse House Plans: Cost, Features, and What to Know Before You Build
If you've spent any time browsing house plans lately, you've noticed the modern farmhouse is everywhere. Board and batten siding, a metal roof, a deep front porch, big windows that let the light pour in. It's a look that manages to feel both brand new and like it's always been there, which is probably why it's stayed popular for so long. At Home Plan DIY, modern farmhouse designs are some of our most requested plans, so we put together a straightforward guide to what the style actually is, what it costs to build, and what to think through before you buy a set of plans.
What Makes a House "Modern Farmhouse"
The modern farmhouse style borrows its bones from old agricultural buildings and dresses them up with clean, contemporary details. A few features show up again and again:
Board and batten or lap siding on the exterior, often in white, gray, or a warm neutral. A simple gable or cross gable roofline, frequently paired with a standing seam or corrugated metal roof. Generous front porches, sometimes wrapping around the side of the house, supported by simple square columns rather than anything ornate. Large windows, including clerestory windows in the gable ends on many of our plans, which bring in natural light without adding a second story. Inside, an open layout that connects the kitchen, dining, and living areas into one central gathering space, usually built around a big kitchen island.
What sets the "modern" apart from a traditional farmhouse is the simplicity. Fewer decorative flourishes, cleaner lines, and a layout that's built for how people actually live today, including dedicated mudrooms, walk-in pantries, and flexible office or bonus rooms.
What Does a Modern Farmhouse Actually Cost to Build?
This is the question we get the most, and the honest answer is that it depends heavily on where you're building, who's doing the labor, and how you finish the interior. As a general planning range, most owner-builders should budget $130 to $220 per heated square foot for construction. That range covers everything from a straightforward build with stock finishes on the low end to a more custom project with upgraded materials, custom millwork, and higher-end fixtures on the high end.
Using that band, here's what a few common sizes shake out to:
A 1,100 sq ft farmhouse plan lands between roughly $143,000 and $242,000 in construction costs. A 1,900 sq ft plan runs about $247,000 to $418,000. A larger 2,300 sq ft farmhouse comes in around $299,000 to $506,000.
Keep in mind this range covers construction only. It doesn't include the cost of your lot, site work like grading or a well and septic system, permits, or financing costs, all of which vary a lot by region and by how developed your land already is. Rural lots that give you that classic farmhouse setting often need more site prep than a lot with existing utilities, so it's worth getting a site evaluation early rather than after you've already bought plans.
Popular Sizes and Layouts
Modern farmhouse plans tend to fall into a few sweet spots. Smaller plans in the 1,000 to 1,300 sq ft range work well for a starter home, a rental property, or a couple downsizing, and they usually keep the whole house on one level with an open great room and a split bedroom layout for privacy. Mid-size plans between 1,800 and 2,300 sq ft are the most requested size in our catalog, since they comfortably fit three bedrooms, two full baths, and a home office or flex room without pushing the budget too far. Larger plans past 2,300 sq ft add room for a formal dining space, a bonus room, or a larger primary suite, and often bring in a garage.
Some of our farmhouse plans also include a loft above the main living area rather than a full second floor. We call these 1.5 story homes rather than two story, since the upper level is typically open to below and doesn't carry the same square footage or framing cost as a full second story. A 1.5 story layout is a good way to add a bedroom or bunk room for guests without building out a full upper floor.
What You Get When You Buy a Plan
Every Home Plan DIY farmhouse plan includes a PDF drawing set plus a material list, so you and your builder have a clear starting point for framing, foundation, and materials estimates. Some of our plans also offer an editable CAD file as a paid add-on, which is worth considering if you know you'll want to make changes to the layout, like moving a wall or resizing a room, before construction starts. If you already love a plan but it's not quite right, our modification service can also adjust an existing design to fit your lot or your family's needs.
Things to Check Before You Buy Plans
A few things are worth confirming before you commit to a farmhouse plan and start pricing out a build. First, check your local zoning and setback requirements, especially if you're drawn to a plan with a wraparound porch or an attached garage, since both can affect how much of your lot the footprint takes up. Second, talk to a local builder or estimator early, even before you buy plans, so you have a realistic sense of regional labor and material costs rather than relying on a national average. Third, think honestly about site prep. A gorgeous rural setting is part of the farmhouse appeal, but if the lot needs a well, septic, or a long driveway, that adds real cost on top of the construction budget. Finally, decide early whether you want board and batten siding and a metal roof, both classic farmhouse choices, since they can cost a bit more upfront than vinyl siding and asphalt shingles but tend to hold up well and keep that signature look for decades.
Our Modern Farmhouse Plans collection is a good place to start browsing if you want to see the range of sizes and layouts available. Two we hear about often are a single-story 3 bedroom farmhouse plan with a full-width covered porch, which is a nice middle-ground size for a growing family, and a compact 2 bedroom farmhouse plan that works well as a starter home or a vacation rental.
If you're still working out your overall project timeline, our home building checklist walks through every step from buying land to moving in, and it's a helpful companion to read alongside this guide.
Frequently Asked Questions
Is a modern farmhouse more expensive to build than other styles?
Not inherently. The style itself doesn't add much cost, but certain material choices that are common in farmhouse design, like board and batten siding or a standing seam metal roof, can push costs toward the higher end of the $130 to $220 per square foot range. A simpler farmhouse plan with standard siding and an asphalt roof can be built for close to what any comparable house style would cost.
Can I add a garage to a farmhouse plan that doesn't have one?
Often, yes, either through our modification service or by working with your local builder to add a detached garage that complements the plan. An attached garage is usually easier and less expensive to add during the design phase than after construction starts, so it's worth deciding early.
Do your farmhouse plans include CAD files?
Every plan includes a PDF drawing set plus a material list as the standard deliverable. Editable CAD files are available on select plans as a paid add-on if you plan to make changes to the layout before building.
What size farmhouse plan is most popular?
Plans between 1,800 and 2,300 sq ft are our most requested size, since they fit a family comfortably without stretching the budget too far, but we carry sizes from just over 800 sq ft up to larger family homes.
Is a loft the same as a second story on a farmhouse plan?
No. A loft that sits open above the main living area is considered 1.5 story, not two story. It adds usable space, often for a bedroom or bunk room, without the full framing and foundation cost of a second floor.
