A new generation of builders tackles the Alaskan wilds to build off-the-grid cabins. First-time builder Nick faces some harsh realities when he can't use the trees on his build site for lumber. Brannon's team develops a unique foundation system to build on permafrost, but they must fight nature every step of the way. Father and son team Jere and Ben take on a massive 5,000-square-foot floating lodge project, the most challenging and dangerous build ever attempted on Building Alaska!
Reality sets in for first-time extreme cabin builder Nick Blanco in Alaska as he fights the tides trying to retrieve pylons for his foundation and realizes he doesn't have the right equipment to dig postholes. Then Brannon's team gets stuck on the muddy trail bringing in more build materials, but eventually makes good progress on the front porch before an unexpected rainstorm shuts them down. Jere and Ben continue to build the massive aluminum barge one weld at a time, but when signs of fall creep in, the colder temperatures start to cause problems.
Jere, Ben and Tim put the finishing touches on the biggest project they've undertaken: building a 112-foot floating barge. They struggle with figuring out how to get a 40-foot trailer underneath it so they can transport it to the water, and hurricane-force winds change their plans and delay the launch. Nick gets help from his family and friends, but the group struggles trying to install the 27 pilings needed to build his dream fishing lodge and warehouse. In the end they solve the problem using some Alaskan ingenuity. Finally, Brannon's cabin starts taking shape as the crew does some heavy lifting putting up the gable end walls.
Nick experiences firsthand just how dangerous living in Alaska can be while hunting for driftwood to build his fishing lodge and warehouse. Jere and Ben's 112-foot barge starts its half-mile journey to the water, but nobody knows if they will make high tide so the barge can float the 13 miles to its new home at Alaska Sea Otter Sound Lodge. Brannon's team fights the rain and the remote building conditions to finally lift the ridge beam into place, hitting a major milestone in his cabin build.
Rain and a muddy trail continue to slow down Brannon's cabin build, but despite their dampened spirits, the gang is able to haul the windows across the two-mile trail. Nick makes a roof design change, and a family fundraiser collects enough money to provide him with some help. Jere and Ben finally get the barge launched and tugged to its new home in Sea Otter Sound so that work on the second story of the lodge can begin.
Nick races to finish his cabin before his mom visits again. Bears are still a threat, so Nick makes sure the electric fence is working. Nick and Kent design and build a "honey bucket," also known as an Alaskan toilet. Brannon and his team finish the front of the cabin, giving it a unique look, and they haul a heavy wooden stove over the trail to install in the cabin. Jere and Ben's crew struggles to get the roof on the guest rooms and the main lodge.
All the builders are in the home stretch in Alaska as they try to finish their cabins and floating lodge. Jere and Ben install interior and exterior siding, but their progress comes to a halt when they run out of stain and nails. So they switch to Plan B, installing the upstairs stove and chimney. Nick's roof is dried in, so he turns to finishing the sleeping loft, building a bathroom and adding outside trim. Brannon's team finishes the exterior siding and interior insulation and installs lights.
Nick's dad, Paul, returns to help put the finishing touches on the cabin, including a unique find that they polish and hang. Nick's mom and stepdad arrive, and Nick's mom is amazed by the finished cabin. Brannon's team builds countertops and railings for the cabin, and his client, Dick, arrives with his family to admire their newly finished lodge. Jere and Ben put in hard work finishing the new Sea Otter Sound Lodge, and the first guests arrive at the 5,000-square-foot floating lodge.
