Building Alaska

Three new couples take on the Alaskan elements. Rookie builders Mike and Teresa construct a cabin, while Paige and Cody create a dog training facility.

Mike and Teresa work on their foundation with a damaged excavator. A faulty nail gun annoys Mike and Kathleen, while Paige and Cody run low on supplies.

Kathleen and Mike's team get dangerously high up to install the ridge beam. Plus, Paige and Cody realise they have the wrong insulation for their log walls.

Mike and Kathleen's team spot bear tracks while on a supply run. Heavy beams slow down Mike and Teresa's plans, while Paige and Cody use a boom truck.

At Paige and Cody's site, mechanical failures prevent the project from finishing before dog sled season. Plus, Mike and Teresa's team take risks to build higher.

Paige and Cody face more setbacks when two workers leave the site and a trailer breaks down. Plus, Mike and Kathleen watch part of their cabin begin to crumble.

Mike and Teresa's team navigate slippery scaffolding. An ordering mistake costs Paige and Cody more time, while Mike and Kathleen deal with broken windowpanes.

All three builds near completion. Paige and Cody race to finish before dog racing season, while Mike and Kathleen lose all their help deep in the mountains.
