Tavren Hollis
What holds a building up and what keeps the weather out that's Tavren Hollis's territory. He writes about foundation masonry and roof construction, from concrete block comparisons to shingle performance in different climates. Tavren has a knack for making material specs readable and genuinely useful for anyone planning a build or renovation. When he steps away from research, you'll likely find him tending his garden or admiring someone else's well-built stone wall.
