Damp & Mould in Letchworth’s Housing Stock
Letchworth Garden City was the world's first Garden City, built from 1903 with distinctive low-density Arts and Crafts-influenced housing and generous private gardens — a markedly different typology to the dense Victorian terraces common elsewhere in Hertfordshire.
Garden City-era housing generally has better original ventilation and more generous room proportions than dense Victorian terracing, though age-related fabric maintenance (render, timber, original single glazing) still needs regular attention.
