Americans who act as their own builder put wood framing into 96 per cent of the houses they finished in 2025, up from 93 per cent a year earlier, in a segment where concrete held 2 per cent. That is according to the United States Census Bureau, whose Characteristics of New Housing file, published on 1 July, counts 1,005,000 single-family completions across the year compared with 1,019,000 in 2024. Owner-built houses are a slice of that market rather than the whole of it, and the framing share across every completed American house sits lower. The National Association of Home Builders put that wider figure at 94 per cent for 2024, the most recent year it has analysed, working from the same Census survey. Jing Fu, Director of Forecasting and Analysis at the National Association of Home Builders, counted 959,000 wood-framed single-family completions in 2024, 3 per cent more than the year before, with concrete taking 5 per cent of the market and steel under half a per cent.
