This paper presents an easy to use method to evaluate early design solutions created by a designer and/or generated by a machine. The method is based on the internal representation of design drawings in the form of hierarchical hypergraphs and on the project specification in the form of a list composed of two types of clauses: the elementary ones and the repeatable ones. These clauses represent goals and limitations imposed on the design by the customer. The evaluation value depends on the soft and hard elements of the specification, which are compared with appropriate accurate values of hypergraph attributes.
