Outside InStyle Creative TeamOutside InStyle is a Los Angeles-based Sustainable Landscape Design Firm. As part of the greater Los Angeles community, we believe in a California whose legacy of creativity and innovation in all aspects of the arts will continue through educated and thoughtful landscape design concepts.

Our designers encourage ecological integrity and work closely with each client to create a sense of place: a garden landscape that evokes a seductive California style, a style that emphasizes beauty and sophistication with the seamless integration of In and Out.

Responsible gardens filled with drought tolerant California, Australian, and Mediterranean plants thrive on low water usage yet will most certainly become a welcome stopover for birds and butterflies. Whether we reuse existing plantings, recycle old materials, or create all new outdoor adventure, every aspect of your design process will be discussed thoroughly.

In the end, we will have created a complement to your existing architecture and fashioned a modern, intelligent design of shapes, textures, forms, and color.

Katrina Coombs is the principal Designer and owner of Outside InStyle Landscape Design. As a native Angeleno, Katrina understands the importance of water conservation while at the same time creating a landscape rich with texture, color, and beauty. Her background in sculpture, painting, and photography inspires her to combine ideas of form and function with color, texture, and drama to achieve a pure and ‘simple elegance’ in design. She is absolutely committed to providing personal attention to detail throughout all stages of her projects, from conception to installation.

Katrina’s strength pulls from all aspects of sustainable design, a forward thinking practice that considers limited water usage in all conceptual plans. Her properties from California to New England, and as far as Australia thrive through well thought-out irrigation systems and wise plant choice. The majority of her work can be seen in the Cheviot Hills area where Katrina has introduced proven drought tolerant non-native and non-invasive flora into our Southern California lexicon. One showpiece project earned her client a $2,000 City of Los Angeles 2010 green rebate and proved noteworthy enough to be featured on the cover of Landscape & Hardscape Design-Build (1/2011).

Katrina Coombs reflection from a mirrored sculpture in a botanical gardensKatrina comes from a long line of design and plant enthusiasts. She spent her childhood playing in the Los Angeles County Arboretum and the Huntington Library and Gardens, two places of adventure and botanical wonder that influence her designs to this day. Her father volunteered for decades at the Pasadena Beautiful Foundation and was instrumental in the design of the San Marino Public Library gardens. Her grandfather, a cancer specialist who loved to use yellow as a “pop” in his Pasadena garden, irradiated his Camellias in hopes of modifying or mutating their inherent color characteristics. His quest was never realized, and to this day the coveted East Asian pure yellow continues to be a rare find.

Katrina graduated with degrees from UC Berkeley and spent several years in the Bay Area before returning to her beloved hometown. Prior to landscape design, she enjoyed life as a corporate retail executive where she gained a clear understanding for the importance of listening closely to clients’ needs.
