Shape grammars are specified that generate houses in the Queen Anne style which dominated domestic architecture in the United States of America in the 1880s; examples are used which are typical for Pittsburgh's historic Shadyside district. Separate grammars are given for the generation of plans and for the articulation of plans in three dimensions. Both grammars emphasize aspects of geometry and overall design and explain how individual parts and features are related to each other.
