This week we’re talking about building for longevity — what actually makes a house last 20 years versus 500. We compare modern American stick framing, European masonry, traditional stone, and natural building methods like cob, rammed earth, and straw bale, and why water, airtightness, climate, and skill matter more than the material itself. In this episode: Why old buildings are still standing and modern ones often aren’tHow American stick framing works, and how it has changedTight houses, moisture, mold, and the “Ziploc bag” problemHRVs, wood stoves, negative pressure, and indoor air qualityRain screens vs older tar-paper-and-siding assembliesRepairability vs 25-year wall warrantiesSpeed, year-round building, and the trades skills gapWhy buildings fail as systems, not as single productsModern European masonry and brick-as-rainscreen constructionDry-in time, cost, and US vs UK laborBrick veneer problems, window upgrades, and out-of-plumb stone wallsMaintenance: masonry vs wood sidingLong-lasting roofs: slate, clay tile, and standing seamTraditional stone, field stone, and lost mason knowledgeLaying stone on its natural bed, and orienting wood the way it grewNatural building / “hippie building”: cob, rammed earth, straw bale, earthships, earthbags, and papercreteThermal mass, overhangs, drainage, and climate-specific designPermitting, insurance, and hybrid buildsQuestion of the week: the tool you most regret buyingTip of the week: spend money on tools that need to be precise _______________________________ Welcome to the Greenhill Forge Podcast, with Eric from the Greenhill Forge YouTube channel, and my buddy Amal, a fellow builder of many trades. In this podcast we’ll talk about where the real world meets experiments in alternative energy, wood heating, metal fabrication, off-grid engineering and self sufficiency, so expect discussions about workshops, tools, fabrication, building, homesteading, and what it actually takes to make those dreams real.
