Veteran Family Builds an Arch Cabin on 10 Acres | Start to Finish by @chasingfreedomhomestead

After nearly 32 years of military and eight years of law enforcement service, Matt is taking on a very different kind of mission. Together with his wife Brenda and their son Isaac, he is building a new life on 10 acres in the Pacific Northwest. A life where they plan to build their own home, grow their own food, and become more connected to the community around them. But before the larger homestead can fully take shape, there's another build underway. An arch cabin, It's curved steel shell may look simple from the outside, but turning that shell into a comfortable finished space is anything but simple. Straight walls, standard framing, and familiar building methods don't always work when almost everything around you is curved. And that means this small cabin is about to create some surprisingly big challenges. From figuring out how to build inside an unusual structure, to turning an empty metal shell into a place that actually feels like home. Matt and Brenda are doing much of the work themselves. The foundation forms are finished the day before the pour. Extra braces help keep them from moving under the pressure of wet concrete. For the footers, they try something different. A woven fabric holds the concrete and follows the shape of the ground. Everything is ready for pouring the concrete. With the footers done, the foundation is finally starting to take shape. The sanding operation took essentially the entire day. The next day is all about getting the stem wall forms ready for another concrete pour. Dozens of 45-inch supports are cut, with seven needed for every eight-foot section of wall. There's a lot of prep work, and this time, there's very little room for error. Not every section is ready yet. Some still need adjusting, others are getting rebar, and a few are clearly off, so the crew isn't rushing ahead. First, everything has to be right, because once the concrete goes in, fixing a mistake becomes a whole different problem. Before the pour, they use a simple trick that's about to save them some trouble. The screws are covered with aluminum and a small amount of Crisco, keeping the concrete from locking them in place. Now, as the forms start coming off, that small bit of preparation pays off. And underneath, they finally get their first look at the concrete. There are a few rough spots, including the area where the pour stopped earlier. But overall, the wall has hardened well. Not perfect, but solid. And as more of the forms come off, they'll finally see how the rest of it turned out. Before the foundation gets covered up, there's one more layer of protection to add, water. Once soil goes back around these walls, keeping moisture away from the cabin becomes much harder. So the crew rolls Blu Max liquid rubber onto the outside of the foundation, covering about the bottom two and a half feet. The hard work is already done. Every anchor bolt has been measured and marked. The holes are drilled through the sill plates. Now the pieces can finally come together. A sill gasket goes down first, creating a barrier between the concrete and the wood. Then the sill plates drop over the bolts and into place. It looks simple now, and that's the payoff. This property has had a house before, but a fire destroyed it, leaving behind an old underground cistern and parts of the original water system. Now, as a new home takes its place, they need water storage again. A new 2500 gallon tank is going right inside the crawl space, hidden beneath the house, and once the floor goes on, getting something this big inside won't be an option anymore. Up to this point most of the work has been below the future house. Now that starts to change. The crew begins laying the OSB subfloor, and with every sheet they're getting closer to the big job ahead. The curved metal structure, Unlike a typical cabin, this one gets its shape from a series of curved metal ribs. There are about 22 of them, and together they'll create the full arch from one side of the cabin to the other. But that curve only works if the spacing stays consistent, so every rib has to sit exactly where it belongs. Once the spacing is right, the ribs can start being locked into place. Each connection makes the frame a little more rigid and brings the separate pieces together. Slowly, the structure starts to feel less like a collection of metal ribs and more like a cabin. A curved cabin creates one problem that keeps coming back. Almost every building material starts out straight. The OSB is no different. Once the panels are up, Matt trims them to follow the metal arch, turning a square edge into the same smooth curve that defines the cabin. Then the outside is wrapped with underlayment, adding a layer of protection before the insulation and siding go on. The cabin is slowly being closed in. The frame is still visible, but not for much longer. This is where the cabin starts getting another important layer. High performance reflective insulation goes over the curved ribs following the arch from the bottom up. Each section is about six feet wide, allowing them to cover a large part of the structure at once. This is one part of the build that's almost impossible to do alone. The siding panels are large and awkward to handle, so this is where friends step in to help. And they need every extra pair of hands. The wind keeps catching the metal, turning each panel into something much harder to control. Even with a full crew, progress is slow. The next morning, the crew moves to the opposite side and starts building the same layers there. Insulation first, then metal. From here, the two sides will rise together, slowly working their way toward the top of the arch. And with every new section, there's a little less daylight coming through. The walls are up, but the cabin still feels closed in. That's about to change. Three windows are planned for this side of the cabin. Two will open up the main living area, while another will bring natural light into the bedroom. Soon, these blank walls will start feeling a lot more like living space. The arch creates the main body of the cabin. But one section will extend beyond that curved shell. This is the bump out. It's a small addition that projects out from the main structure and changes the cabin's simple arched outline. This section will also include two openings, a small window and a door. The bump out is small, but it still has to become a complete part of the cabin. Now, the open framing starts to close in. OSB gives the walls a solid exterior, while the roof structure begins to take shape above. This is also where two very different shapes start coming together. The straight lines of the bump out meet the body of the cabin, and little by little, what looked like a separate addition starts becoming part of the same structure. The bump out is taking shape, but now the clock is ticking. Rain is expected in just a few days, and Matt wants to get this part of the cabin protected before it arrives. That means finishing the house wrap first. So the next few days aren't just about making progress, they're about beating the rain. With the roof OSB in place, the bump out is one step closer to being protected from the weather. But before the metal roof can go on, it needs the right layer underneath. And not just any membrane will work here. Metal roofing can get extremely hot in the sun, so he uses an ice and water shield made specifically for high temperatures under metal roofs. Until now, the bump-out has simply been an extra section attached to the cabin, but now we know exactly what it's going to become. A laundry and mudroom. That gives this small addition a clear purpose. What started as a few extra walls outside the arch is now becoming a space they'll actually use every day. Two windows will bring natural light into the new laundry and mudroom. And for the entrance, they find a door with a built-in blind, but there's a catch. The door has some cosmetic damage. The damage is minor, but enough to get the door for half price. Pretty good deal. Once the cabin is closed in, getting underneath it won't be so easy, so the crawl space needs its own access point. Matt creates a dedicated opening that will provide a way into the space beneath the house. That access could become important later, especially with the large water tank already sitting down there A crawlspace entrance may not seem like a big part of the build until something goes wrong underneath the house. And they already have a good example. The water tank has a problem with its valve and fixing it means getting back underneath the cabin. So this space can never become completely inaccessible. A dedicated entrance gives them a way in whenever something below needs attention. Maybe not today, but sooner or later it probably will. Building a crawlspace entrance is one thing. Making sure it works for years is another. Water is one of the biggest concerns. It needs good drainage and protection from moisture. Otherwise, the access point meant to solve problems can become a problem itself. Location matters too. Pipes, tanks, and wiring may all need attention someday, so they need to be easy to reach. No one will notice this access point when the cabin is finished, and that's fine until the day they need it. After working on a giant curved roof, This one should feel easy. And for the most part it does. There's no huge arch to cover this time. No long curve to follow. Just a much smaller metal roof on the bump out. But easier never means problem free. The edges still have to come together cleanly. A few pieces need adjusting. And even the roofing tape decides to put up a fight. Small stuff. The kind of stuff that can somehow eat up half a day. Compared with the main arch cabin roof, this one is much easier, but it still has a few tricks of its own. Building the cabin is only part of making this property work. They also need to make sure they can actually reach it when the weather gets bad. With winter ahead and the spring thaw coming after that, the driveway needs a stronger surface. So the family starts preparing the busiest parts of the road for several loads of rock. Three loads of rock go down, building up some areas to around six inches deep. And even that isn't quite enough. Two more loads will still be needed. It's a lot of work for just a road. But on a homestead, it matters. Matt and Brenda have been learning from the very beginning, taking on jobs they've never done before, figuring things out when the first plan doesn't work, waiting on materials, working around the weather, and there have been plenty of smaller jobs in between. Some took hours, some took days, some needed friends to show up and lend a hand, but every one of them moved the cabin forward and now something is changing. Openings that once looked like empty spaces in the framing are becoming actual windows and doors. These are small changes compared with pouring a foundation or raising an entire steel arch. But visually, they change almost everything. Progress isn't always measured by the biggest jobs. Sometimes, one window changes the whole room. One door suddenly gives a building an entrance. And little by little, the construction site begins to disappear. What replaces it is the place the couple has been working toward it all along, not finished yet, but finally starting to feel real. They wrap and seal each opening, creating a barrier against the weather before the exterior is finished. And as they work, they're not afraid to try a better approach. That's been part of this build from the beginning. Learn something, try it, and when they find a better way, adjust. One challenge has followed Matt and Brenda through almost this entire build, the weather. In the Pacific Northwest, rain can be part of the routine for much of the year, and when they're building outside, they've also learned pretty quickly how to adjust their plans around it. Not every part of this cabin starts with a finished plan. The fireplace is a good example. Brenda has an idea for how she wants this corner to look. Matt's job is to figure out how to make it work, so they start with the hearth and work from there. And there's plenty to figure out before this corner is ready. Sometimes the plan only becomes clear once they start building. The first design changes. The size changes. They try different tile layouts until they find one they like. And the chimney takes some planning too. It's not about having every answer from the beginning. They try a few things and figure out the rest along the way. This fireplace is turning out to be one of those projects. Bump out will eventually open onto a deck and a sitting area, but that part of the build is still a while away. For now Matt uses the time to build a simple set set of temporary steps. Four steps seemed right at first, but the bottom one would sit too low where rain, snow, and mud could become a problem. So four becomes three. The insulation is going in, but he doesn't want the future wiring and plumbing running right against the metal shell, so he adds a small There's a small pony wall along the bottom of the cabin. It creates a protected channel where those lines can run later. Away from the hot metal and the insulation, it also gives them a wooden surface for things like electrical outlets. It's a simple idea, but it means making about 38 individual pieces to carry that same channel around the cabin. A lot of repetitive work now. In the long run, it will be much easier than trying to find space for all those utilities later. Fiber cement siding is strong and durable, but installing it takes some planning. It starts with the first row. If it's off, every row above it can be off too. Water is another challenge. Metal flashing is added in key areas to guide rain away from the wall and keep it from getting behind the siding. Then, the cuts. Around the windows and corners, every piece can be a little different. At first, finding the right measurements takes some trial and error, but Matt finds a method that works better. Once he gets that system down, the pieces start fitting much better. And the whole job starts moving a little faster. From the outside, the arch cabin is finally starting to look like the place Matt and Brenda imagined. But the story behind it is much bigger than the building itself. Ten acres in the Pacific Northwest. A homestead, and a chance to build more of their life with their own hands. That sounds exciting when you say it quickly. Living it is different. Trying something you've never done before, getting a plan wrong, changing it, and starting again. That may be one of the most important parts of their story. They didn't arrive here knowing how every part of this cabin would come together. They figured it out together, and with help when they needed it. Now, most of the exterior is behind them. There is still a lot waiting inside, but the hardest part may already be visible in what stands here now. An empty piece of land has a cabin on it. An idea has a shape. And a family that came here hoping to build a different life has already proven something important.
