Full Movie: I Built a Warm Tree Trunk Shelter Alone with Underfloor Heating & Catch Eels

Full Movie: I Built a Warm Tree Trunk Shelter Alone with Underfloor Heating & Catch Eels In this full survival movie, I spent days completely alone in the wilderness building a warm tree trunk shelter with an underfloor heating system, while relying on eel catching and wild cooking to survive. Using only natural materials and primitive bushcraft techniques, I transformed a massive hollow tree into a secure, insulated living space. I carefully carved the interior, reinforced the structure, installed ventilation, and engineered a simple underfloor heating system designed to retain warmth during freezing nights. To sustain myself, I crafted traps and caught fresh eels from nearby water sources, preparing survival meals over an open fire. This video documents the complete process — from shelter construction and heating design to food gathering and daily life in isolation. This project highlights tree trunk shelter engineering, winter survival skills, primitive heating systems, and long-term solo bushcraft living. It’s a realistic and immersive look at off-grid life in harsh natural conditions. If you enjoy full survival movies, hidden tree shelters, underfloor heating builds, and authentic wilderness catch and cook experiences, this journey will keep you watching until the end. #treetrunk #wintersurvival #bushcraft #underfloorheating #catchandcook #eelfishing #solosurvival #offgridliving #survivalmovie #wildernesslife
