the hospitable workplace PHOTOGRAPH: SHANNON MCGRATH Designers today are acutely aware of the influence of hospitality design in workplace interiors. Now, that does not mean slides, swings, and beanbag chairs. It's maturing with layers of sophistication- and often is an intervention in an existing building-as seen in three featured interiors in this issue. For ad agency Lowe Campbell Ewald (page 56), a Detroit warehouse is reconceived as a cool workplace for the creative class. Zendesk's San Francisco home (page 64) is, like the company, following the adage of less is more. And the Compulsive Productions video studio (this page and page 70) demonstrates that a small office can pack a wallop of visual interest. contract
