Traditional construction guzzles resources—65% more materials, high CO₂ from cement, and on-site trash polluting landfills. Sustainable Builders flip it: recycled steel cuts emissions 95% in hydrogen processes, prefab minimizes errors, and modular steel recycles fully for circular economies. In 2025, codes favor mass timber for mid-rises, reducing footprints while boosting seismic strength. Sustainable Builders engineer for longevity—thermal bridges eliminated, low-VOC paints, and durable composites resist mould in humid climates. Traditional homes suffer cold spots, higher maintenance (20% m
