Rays of early-morning sunlight gently peek through the windows, easing you awake. Looking down from the sleeping loft, you see everything you need: a pine table; a box piled with hardwood, split and ready for the woodstove; and a compact kitchen in the corner. This is the cabin dream.

In this article, I’ll show you how to build a 14-by-20-foot cozy cabin featuring a sleeping loft over the porch for about $4,000. Who can resist it?

My own cabin adventure began in 1986, when I built one as an inexpensive place to stay while constructing my house — that’s when I began learning what makes cabin design and construction successful. (I’ve always had a debt-free approach to developing my property.) The four years I lived in this cabin were a good time in my life — perhaps one of the best. I fondly recall the simplicity of waking each morning with the sole purpose of building my own house, working well into the evening.

What follows is a cabin plan (I’ve included a full Cabin Assembly Diagram) with the hands-on know-how I wish I had 20 years ago. It won’t replace the need for basic carpentry skills, but it will alert you to the main challenges of framing a cabin and how to clear the most important hurdles. And even if you never build a cabin of your own, these basic instructions will be useful anytime you need to build a garage, shed or other outbuilding. (For more on the author’s cabin experience, see Our Life in a One-room Cabin)

I believe in building for the long haul. When it comes to cabins (and everything else for that matter), this means working to the same standards of durability and beauty that you’d apply to a full-size house, even though the style, size and soul of a good cabin are entirely different. I’m sold on durability because it takes such small amounts of extra care, materials and money to yield a huge increase in longevity. Although a cabin certainly can be framed less stoutly than the design I’ll show you here, I’m convinced the wisest use of resources often means going beyond what’s merely good enough.

A Firm Foundation

Every well-built structure begins with the foundation. In regions where frost isn’t an issue, site-poured, 6-by-16-by-16-inch shallow-depth concrete pads work just fine. If this is similar to the approach used on new houses in your area, then it’s OK for use under your cabin.

Cold climates are a different matter, and one of the best cabin foundations you can choose is established easily with minimal tools and time. Concrete piers extending below the frost line, poured within round cardboard tubes, are a time-proven approach to lightweight construction that offers a couple of advantages. Besides raising the structure off the ground and isolating it from the annual freeze/thaw movements of the soil, concrete piers provide good support around the perimeter of your cabin, without the need for full-scale forming and pouring.

In this cabin design, you need one pier at each corner of the cabin, one in the middle of each long side, three piers spaced evenly on the front of the porch and one in the middle of the rear wall. In light soil, it’s reasonable to dig the 10 holes you need for 8- to 12-inch-diameter pier forms using a long-handled shovel. Otherwise, call in a neighbor or contractor with a tractor-mounted auger. You can use 8-inch concrete piers, but the larger size is more forgiving if you don’t get the alignment just right.

The best way to mark your foundation outline is with 12-inch spikes pushed into the earth and connected with nylon string. (See “Choose a Rock-solid Start,” below, for layout tips.) Regardless of the foundation design you choose, the main construction challenge is the same: leveling the top of the foundation pads or piers. A laser level is easy to use and even allows a person working alone to level a foundation successfully. You don’t need to buy a laser level for this project, but it’s definitely worth borrowing if one is available from a friend or neighbor.

When setting concrete pier forms in the ground, dig the holes large enough to allow room for side-to-side adjustment. The outside edges of the pier forms should extend a bit beyond the outer dimensions of your building. As inexpensive insurance against frost jacking of foundation piers (when the piers are pulled toward the surface by seasonal freezing, even though they extend below the frost line), wrap the outside of each pier tube with black polyethylene plastic before setting them into the holes and packing soil around them. While the concrete is wet, vertically embed five-eighths-inch L-shaped threaded metal rod anchors, extending at least 7 inches above the concrete, short end down. Later on, these will hold down the base of the floor frame.

Building the Floor Frame

There are many ways to frame a cabin floor, but I favor the timber-rim approach for a couple of reasons. “Timber rim” refers to a load-bearing frame of timbers that defines the perimeter of the floor area. It’s better than a continuous foundation wall because it eliminates the need for lots of block work or a poured foundation, and it offers great stability. For this project, it provides continuous support for a building that’s held up at only 10 points around its perimeter. Another plus is that timber-rim construction is durable and simple for first-time cabin builders.

Start by gathering rot-resistant 6-by-6 timbers for the outer rim. Timbers for the ends of the cabin and porch should be long enough to do the job in one piece. If you need to splice two timbers together for the 20-foot cabin sides, that’s fine. Just locate the splices directly on top of your concrete pads or piers. (It is possible to get away with thinner pieces of wood here, but that would require adding more piers — an option that’s probably less attractive than dealing with thicker timbers.) Be sure to make half-lap corner joints to connect the rim timbers.

Measure, mark and drill 1-inch-diameter holes in your 6-by-6s for the five-eighths-inch threaded rod anchors you embedded in your concrete piers, then settle the timbers in place over the rods.

Before bolting down the timbers, double-check that the top surfaces of the 6-by-6s are level to within one-eighth inch of each other. Pouring concrete is coarse work, and it’s possible the foundation piers aren’t exactly the same height now that they’ve hardened. Now’s the time to identify and correct any such errors. Install shims underneath the uneven timbers to make them level; bolt them down tightly under 2-inch washers; then check one last time with a level. You now have a sturdy timber rim on which to begin building the cabin. As long as the bottom of the timber rim is at least several inches above the soil, natural ventilation should keep this structure strong for many decades.

The timber rim you just installed supports floor joists and headers (the frame around the joists) that in turn form the cabin and porch floor. By running joists across the 14-foot width of the building, you’ll have the stiffest possible floor for a given width of joist, minimizing squeaks and ensuring long-term durability. As a rule of thumb, 2-by-10s spaced on 16-inch centers across the span of this cabin will give you a good floor. But because the type of wood affects the total allowable span — building codes may vary where you live — double-check floor joist sizes with your local authority. You might consider using 2-by-10 joists across the porch and 2-by-12s for the main floor (but if you do, remember to use a 12-inch-wide header for the main floor, or your joists will be taller than the floor frame). Using 2-by-12s raises the cabin floor slightly, creating a lip at the door that helps repel water and snow.

Regardless of the floor framing wood you choose, use five 3 1/2-inch nails on each joint connecting the floor joists to the headers. Make sure the edges of your floor frame are perfectly straight and use a string as a reference to ensure that this happens as it should. Use 3 1/2-inch hot-dipped, galvanized nails driven at an angle to connect the floor frame to the timber rim. You also can use galvanized connector plates.

Now’s the time to apply a floor surface to your joists, and that means you have a decision to make: If you want flooring that’s easy to build, inexpensive and requires no maintenance for a cabin that won’t see much cold weather, then three-fourths-inch softwood planks are the way to go. Even left completely unfinished, these form a fine, rustic floor that’s easy to sweep clean. Over time, bare wood like this also takes on a burnished beauty that’s as pleasant to look at as it is to live with.

Or do you want a better floor to keep out drafts and bugs, while retaining simplicity? Then consider shiplapped floorboards. They’re one step up from square-edged planks, offering all the same advantages as plain boards, while also preventing board-to-board gaps. The best floor option is five-eighths- or three-fourths-inch plywood, though this makes sense only when you’re planning to apply a finished floor material over the top. Plywood keeps drafts out and adds an element of rigidity that dimensional lumber can’t match, but it also looks unattractive, especially in a cabin.

IllustrationWall Framing

With your rough floor in place, you can now build the walls. Stud-frame construction is still the most popular approach for residential projects, and it makes sense for cabins, too. Although you can save money by framing with 2-by-4s, I recommend 2-by-6s instead, even if you won’t be insulating. The extra 2 inches of frame depth is stronger, looks better and offers greater storage opportunities for small items sitting on shelves between the studs.

Stud-frame walls have three main parts: the plates (horizontal members that form the top and bottom of the walls); studs (vertical frame members); and lintels (horizontal members that span doors and windows).

Start by cutting one top and one bottom plate for the rear wall — the one opposite the door. Make these plates out of one 2-by-6 each, then temporarily screw them together so all sides are flush. Joining them together ensures accuracy of the marks you make to show stud location. Make these plates 13 feet, 1 inch long. This way the completed front and back walls will measure 14 feet wide when flanked by the two long walls that will go up on each side of them.

With the pair of plates on edge, use a carpenter’s square to draw lines across the edges of the plates at the same spot. Each pencil line shows where one side of each stud should be located. An “X” marks the side of the line where the stud needs to sit. Studs measuring 92 1/2 inches long should be spaced 16 inches apart from center point to center point, with extra studs where door and window openings will go later. Before you frame openings for windows and doors, you need to know the sizes of the openings required for them. Make window openings 1 inch wider and 1 inch taller than the overall size of your window (1 inch wider and a half inch taller for a prehung door, when you get that far).

Remove the screws that temporarily held the top and bottom plates together, separate these pieces about 8 feet apart (with the bottom plate near its final place on the wall), and then position your wall studs between them. Begin by nailing the plates to the ends of the full-length studs, then cut and add shorter studs to form the window opening. Use three 3 1/2-inch nails per joint. If you’re planning to build insulation into your floor, add a second bottom plate to the wall to raise it up. Now gather some eager volunteers and get ready to heave the wall upright and into position.

This is an exciting moment, but you’ll need a few tools to succeed. In addition to a framing hammer and some 3 1/2-inch nails, an 8- to 10-pound sledgehammer is helpful for jostling the wall into final position, and you’ll need a 24- to 48-inch level to check and align its orientation. Raise the frame with a couple of helpers, then push, pull and pound it into alignment with the edge of the floor frame. Use your level to help align the wall so it’s perfectly vertical (plumb), and then drive two nails into each space between the studs on the bottom plate, extending down into the floor boards and header.

Your wall is up and secure now, but it’s not yet strong. Brace it with some long pieces of lumber extending to the ground (you’ll take them off later, so use the good stuff), then repeat the wall framing process for the two neighboring side walls.

When you’ve framed the last wall (the one with the door) and raised it, check and adjust all walls so they’re straight and plumb. This may take some time, but don’t continue until you’ve correctly finished this detail. Use taut strings (as you did when assembling the floor frame) to make sure the top edges of the walls are truly straight. When you’re satisfied, get ready to cut and apply another layer of 2-by-6s over the existing top plate. You’ll need to arrange these parts so they overlap the joints between wall segments (see “Post Top Detail,” at the bottom left corner of the illustration), but there’s another detail you need to address first.

Our Post Top Diagram shows you how two 6-by-6s or log posts should be installed extending from the top corners of the side walls to provide support for the porch roof. Begin by fastening two 6-by-6 vertical posts to the front corners, then rest three horizontal 6-by-6s on top, extending to the porch posts temporarily supported by props of lumber. When all this is in place, tie everything together with a second 2-by-6 top plate.

What you should have at this stage is the four walls of the cabin raised, with an additional 4-foot frame extension from the cabin’s front wall, which will support the porch roof. The roof fits over the cabin walls and porch in exactly the same way. Here’s a tip: In general, you can use 12-inch spikes to hold together large framing posts, such as the 6-by-6s described above, but you have to drive them into pilot holes. Although spikes aren’t strong enough to resist shear loads, they do an excellent job holding one part in place over another.

For siding, I recommend wall planks because they look so much better from the inside of your cabin. If you are looking for inexpensive siding, or you plan on insulating the wall’s interior and adding interior siding (covering the 2-by-6s from the inside), you can use plywood or oriented-strand board (OSB) wall siding panels.

Cabin Kits

Many people dream of building a cabin or cottage in the woods, beside a lake, along a bubbling brook or on top of a mountain with sweeping views. But cabins are not just for wilderness living. They also can offer cozy space as a guest room, an artists’ retreat, a craft center or a small office.

The cabin kit manufacturers listed below are divided into three construction categories: log, frame and panel. Most kits consist of the necessary materials for the exterior walls, interior wall studs, roof and floor, and include windows, doors, fasteners, trim and construction manuals. The kits do not include foundations, insulation, or electrical and plumbing packages. The base prices listed below do not include shipping costs.

To find the cabin that best fits your budget and construction experience, read each company’s literature carefully and then ask lots of questions before you buy a kit.
