A sample of twenty-eight architects were interviewed about the way they designed houses. In view of their anti cipated drawing ability, it was expected that they might be able to express ideas they have about the way people live in houses by undertaking a drawing. This method of interviewing architects was thought to be novel. The pa per describes how the technique was developed, with par ticular emphasis on problems associated with ensuring that the technique was valid and reliable. Alternative techni ques are discussed and, with reference to some of the re sults obtained, the paper concludes with other studies which might benefit from this method.
