PreVision Design

Provides technical studies and reporting for proposed developments at the intersection of design, regulation, and the built environment. Services include quantitative shadow impact assessments, Section 295 compliance, shadow envelope studies, and location-duration heatmapping for CEQA and planning review. The firm also collaborates during design to reduce or eliminate shadows on parks, plazas, and other sensitive areas. Daylight access analysis evaluates natural light conditions and effects on surrounding properties, while photorealistic visual simulations and photomontages communicate proposals to stakeholders, planning commissions, and communities. Independent peer review covers shadow studies, visual simulations, and environmental analyses prepared by other consultants. PreVision Design is based in San Francisco and serves jurisdictions throughout California.
