Tight Spaces: Hard Architecture and How to Humanize It

Sommer defines hard architecture as environments 'designed to be strong and resistant to human imprint' that seem 'impervious, impersonal and inorganic' to inhabitants . His examples are concrete: airports where chairs are bolted to the floor to drive patrons toward concessions, picnic tables cemented into the earth making large gatherings or shade-seeking impossible, public toilets advertised as indestructible that drive vandals to dynamite in 'a desperate attempt at a human imprint' . The common thread is design that prioritizes maintenance, control, and durability over occupant use, producing spaces that actively discourage habitation, personalization, or comfort. Sommer identifies seven institutional types where hard architecture dominates: mental institutions, prisons, airports, zoos, schools, offices, and universities .

Sommer's 1969 Personal Space focused on individual spatial behavior—how people defend invisible boundaries, regulate interaction through distance, and respond to invasion. Tight Spaces scales up to public and institutional settings, arguing that the same behavioral principles apply to how buildings shape occupants. A Journal of Education review noted the book is 'rooted in the same soil' as Personal Space but focuses on 'the human concerns and psychological consequences of public spaces,' making it a 'valuable complement' to the earlier work . The key shift is from documenting how people cope with space to arguing that designers should stop creating spaces people must cope with. Personal Space described behavior; Tight Spaces prescribes a design ethics.

Soft architecture is Sommer's alternative: environments that 'welcome and reflect the presence of human beings' rather than resisting it . The principles include flexibility (movable furniture, adaptable arrangements), transparency (blurring indoor-outdoor barriers, bringing in light and views), and personalization (allowing occupants to modify surfaces, arrange spaces, and leave their imprint). Sommer argues that even hard buildings can be humanized in small ways—a teacher personalizing a classroom can create 'a refuge in a hard building or a base camp out of which efforts to humanize the environment can gradually radiate' . The University of California dormitory example illustrates this: after years of futile enforcement against posters, the administration supplied paint and allowed students to decorate freely, resulting in happier students and lower repainting costs .

Lawrence Dietz's 1974 review was sharply critical of Sommer's method. Dietz acknowledged the value of the topic but stated plainly: 'It would be valuable, indeed, to read a carefully researched, well-documented book on this subject. Unfortunately, Tight Spaces isn't it' . He noted that where literature on design and users exists (mental institutions, prisons, schools, zoos), Sommer gathered quotations effectively. But where no literature exists, 'it is left to the readers to bring their experiences to flesh out Sommer's arguments or else take them on faith' . Dietz also criticized Sommer's attitude—'lurching from a benign, blowzy, with-it humanism to out-and-out petulance'—and his failure to conduct basic research, such as asking a janitor about the 'mysterious red sawdust' he observed .

The subtitle signals that Tight Spaces is not purely diagnostic but prescriptive. Sommer does not simply indict hard architecture; he argues that existing buildings can be modified to support human needs. The Journal of Education review noted Sommer is 'not a critic without solutions,' consistently offering pleas for both 'the future creation of soft, or humane, architecture and the humanizing of presently hard architecture' . This practical orientation distinguishes the book from purely theoretical critiques of modernist design. The epilogue chapter, 'The Horse Inside the Cart,' makes explicit the argument that designers have reversed priorities—form has been put before function, and the book aims to restore 'a functionalism based on user behavior as a guiding principle'.

Prisons receive extended treatment as the paradigmatic case of hard architecture. Sommer's chapter 'Models and Fads in Prison Design' examines how carceral environments are constructed to prevent escape and resist damage, producing conditions that generate violence and psychological deterioration. His aim, according to one account, was to apply architectural strategies used in mental health facilities to the prison setting, with the primary concern being 'whether hard architecture instills any sort of reform on the individual, or whether it merely perpetuates the idea of punishment' . Sommer encountered resistance from prison administrations—in one institution he was barred from interviewing guards, in another from speaking with prisoners—illustrating the institutional opacity that hard architecture both expresses and enforces .
