Lili designs landscapes and natural environments that connect people, architecture and place.
Led by John Hreno, the studio works from Southern and Northern California, serving homeowners, institutions and communities. We believe a landscape should belong to its setting and enrich the lives unfolding within it. Each project begins with listening—to the land, the architecture and the people who will use it.
Lili’s project teams bring together exterior designers, licensed landscape architects, architects, horticulturists, ecologists, engineers, craftspeople and builders according to the needs of each project. John Hreno leads the studio’s design vision and interdisciplinary collaboration.

Founder + Design Director
John brings a hands-on approach to landscape design, connecting planting, materials and spatial composition with the coordination needed to carry a project through to completion. His work spans intimate residential gardens and larger shared landscapes, with a consistent interest in how places feel, how they are used and how they change over time.
John grew up between the mountains and beaches of Southern California, wandering its wild places and learning, long before he had words for it, how the land influences the way we feel and experience life.
He first studied psychology, drawn to the inner landscapes of human experience, before turning to architecture. At the University of Southern California, he quickly gained recognition, earning an international design award and the Gamble House Scholar-in-Residence Fellowship. Yet buildings alone could not contain his curiosity. After several years in architecture, and a remarkable introduction to landscape practice at the Getty Villa in Malibu, his attention was drawn toward the natural world.
John has designed places and experiences across the United States and abroad: quiet gardens, civic landscapes, urban spaces and ecological systems. Whatever the scale, his work begins with a simple conviction—every place holds a larger idea waiting to be revealed through story.
He approaches design through light, movement, texture, memory and time. Architecture and landscape are not separate territories, but parts of one continuous experience: a path opening toward the horizon, shade gathering beneath a tree, water carrying the sky, a place where people feel more connected to one another and to the earth.
John leads through curiosity and collaboration. He is a designer, maker and problem solver, drawn most deeply to work that brings lasting social, emotional and ecological value. His purpose is to create places where life can take root for all to thrive.

Sustainability + Native Plant Specialist
Marlene creates thoughtful, water-conscious landscapes that celebrate the quiet beauty of nature and the power of ecological connection. With academic roots in both Landscape Architecture and Art History, her work bridges artistic composition with natural systems, creating outdoor environments that feel timeless, resilient and alive.
Each design reflects a commitment to the land, not simply as a backdrop, but as a living system to be understood and nurtured. Her approach integrates core ecological principles: conserving energy and water, building soil health, supporting pollinators, enhancing biodiversity and prioritizing native plants that form deep relationships with local wildlife.
Rather than forcing a landscape into place, Marlene listens to the site, its rhythms of light and shade, its seasonal shifts, its capacity for renewal. As a Firewise qualified designer, she layers fire-smart strategies with natural beauty, creating landscapes that sustain life, soften the human footprint and restore a sense of balance between people and place.
She brings clarity, sensitivity and ecological purpose to every landscape, where beauty meets sustainability, and where a connection to nature can truly take root.
Our approach brings the character of each place into the experience of everyday life.
