Background and aim - Lack of privacy is a prominent issue in contemporary offices. This study aimed to identify interior design features that jointly influence satisfaction with privacy and noise in the office workspace, and estimate their predictive power. This knowledge can inform strategic workplace design. Methods - Eight design features were defined that were expected to influence visual, acoustic and physical privacy, noise from other people and acoustic quality, and which would be easy to report for users. Data were collected through an online survey among office workers in the Dutch public sector (N = 323). The joint impact of design features on the experienced privacy and noise was calculated through ordinal regression analysis. Results - The data indicate that small, relatively isolated rooms predict privacy and noise satisfaction better than privacy screens, soft flooring, and visibility control. Workspace soundproofing increases satisfaction with sound privacy and acoustics, but it does not reduce noise annoyance. Originality - This study operationalizes architectural privacy along several dimensions and from a user perspective, and hierarchically relates them to specific workspace satisfaction outcomes, generating actionable insights for workplace designers. Practical and social implications - The study can serve as a source for evidence-based workplace design and management that aims to balance user needs for privacy and quiet against their need for social interaction. Currently, this balance is especially important because hybrid working may increase the need for informal interaction at the office while there still is a need for privacy and quiet spaces.
