A series of illustrated lectures advocating a reform of domestic architecture, focusing on small and middle-class homes. The authors criticize customary ornament and concealed construction, and promote functional planning, honest materials, and an architect’s involvement through furnishing. They call for handcrafted decoration, painted wall scenes, simple durable furniture, and spaces suited to everyday life and children. Later lectures address education in art, cooperation in building, and practical principles for designing small houses and cottages, with plans and plates that demonstrate economy, natural beauty, and domestic convenience.
