The Habitat team combines unparalleled expertise in horticulture, botany, design and construction.
Founding Principal & Lead Living Wall Designer
Working at the intersection of botany, architecture, interior design and urbanism, David has applied his passion for plants to a growing list of innovative projects, building a broad variety of modern, human-centric spaces with abundant plant life at their heart.
David is a pioneer in the field of vertical gardens. He holds a degree in Environmental Horticulture Sciences from California Polytechnic University at San Luis Obispo. He credits his time spent studying at the Royal Botanic Gardens in Kew, London, with setting him on the path to living wall design. It was at Kew that he came to appreciate the beauty of epiphytic plants – those which have naturally evolved to grow vertically on trees.
David sees his work as an integral part of a public shift in consciousness towards a renewed desire for closeness with nature and an appreciation of the restorative effect of plants, especially in urban environments. For David, designing living walls affords the chance not only to promote awareness of native and endangered plant species but also to have a direct impact on quality of life.

Favorite Habitat Horticulture Installation:
Foundry because of its scale and the fact that I have been caring for it for 4 years. I love the way it makes you feel small when you walk into that lobby. The Philodendron 'Congo' are also massive and I think it is cool to see a plant that large on a living wall.
Favorite Plant Species:
Kalanchoe beharensis aka the 'felt bush'. I like them because they are hardy and grow every tall. They are also fuzzy and have a lot of character...they look very sculptural.
Design Project ManagerBio
Head of Plant ProcurementBio
Derek has been a design engineer at Habitat Horticulture for just under a year, which he describes as “some of the best months of my professional career!”
Derek earned her bachelor’s degree in environmental design with a concentration in architecture from the University of Manitoba. He also has a master’s degree in building technology from the Technical University of Delft in The Netherlands.
A hint of his future with Habitat Horticulture came with Team Netherlands during the Solar Decathlon Europe Competition in 2020. Contributing to both the architecture and engineering teams, he was appointed as a building services and sustainability engineer with sole responsibility of design, structure, function, operation, and integration of the PCM Active Living Wall, which contributed to winning eight awards.
Favorite Habitat Horticulture Installation:
Beverly Hills Residence. While the living wall is quite beautiful on its own, the architecture, structure, and overall environment establishes a unified, unique, and harmonious identity. As this living wall stands atop a saltwater pond filled with a variety of different species, I believe that any integration of our systems that not only includes other means of nature but are specifically designed for them are amongst our most successful projects. In addition, this project includes some unfavorable and unique conditions for a living wall application which required a complete team effort. As a result, this project further illustrates what can be achieved from the individuals that make up the Habitat Horticulture team from all departments.
Favorite Plant Species:
The Spider Plant. As I have personally been involved in various R+D projects that directly involve this plant, it is both a robust and performative houseplant with a unique aesthetic. Aside from its associated biophilic effects, the plant is capable of consuming levels of CO2, harmful airborne particulate matter, harmful volatile organic matter, it produces higher levels of oxygen then most, and if enough of them are grouped together in a confined space, it has the capability of mitigating relative humidity and comfort conditions.
Head of Marketing & CommunicationsBio
Lucía plays a vital role in our design process, helping to determine how we incorporate our living walls into the buildings and spaces they form a part of. That can mean working an installation into an existing building or helping to place it seamlessly into plans for a new construction. Her detailed 3D renders and architectural drawings give our clients the chance to see how our installations will transform their space, and later they guide our installation team as they build. Lucia holds a Master of Architecture degree from the University of Buenos Aires, Argentina. For her, the most inspiring spaces are those that evoke emotion by melding the built environment and the natural world. With her experience in large-scale commercial projects and residential buildings, she has an acute understanding of proportion and a keen spatial intelligence. She is also a true plant lover, creating botanical illustrations and artwork in her spare time.
