Greenspace Collective is a Los Angeles based full-service landscape design + build firm specializing in site-specific landscapes that respond to client needs and exist harmoniously within the surrounding environment. We create vibrant, well-built gardens and exterior spaces that are usable and environmentally aware, integrating climate appropriate and native plant species with material finishes that complement the existing architecture.

With a trusted team of highly-skilled designers, artisans and builders we efficiently manage our projects from concept to completion. From site preparation and water management solutions, to hardscape, planting and everything in between, we give utmost attention to detail and provide clear communication. We love what we do and share our enthusiasm and passion with our clients. We check in on our projects long after completion as gardens are ever evolving.

Greenspace Collective was founded by Katy Valentin who has worked in leading landscape design + build firms in Northern & Southern California for 20 years. She is a licensed CA landscape contractor, studied Ecological Horticulture at UC Santa Cruz, and landscape design at NYBG.
