“Barbara worked with us to redesign and replant the back and side gardens of our 19th century carriage house in Baltimore, including a multi-season cottage/pollinator garden, creating new walkways and sitting areas, and incorporating new plants into an existing mature landscape. Always the professional, she brings a deep knowledge of plants and garden design to a truly exciting and fun collaborative process. She was generous with her time and always available to answer our questions. In addition, we used her preferred contractors for stone work and irrigation, and they all spoke very highly of her, both personally and professionally. We look forward to many years of gardening together.

London Landscapes did an outstanding job working on our backyard to create an outdoor living space which is now our favorite part of the house. Her designs are creative, thoughtful, and reflective of her goal to help clients transform a space to meet their specific needs. My wife and I could not recommend her more highly.”


Personable, expert, high integrity, creative, on time, good value and  great results – Barbara scores highly on all of these dimensions. We moved into a house that is really oversized for the lot that it’s on, and furthermore it sticks out into a three way intersection. Barbara was referred to us by a decorator. We asked her to help us soften the mass of this house with new soft and hardscape. We also asked if there was any way to put a pool in our not very large back yard without taking over the entire yard. I think she may have taken on this work for the sheer challenge! She did both of these things and exceeded all our expectations.  We love the perennials that she has chosen, and the oasis that she has created in our yard. I am not adept at gardening and don’t have time for a lot of maintenance, and yet this yard just keeps on giving. We love it. Furthermore, we love Barbara. She is such a pleasure to work with and I now count her as a friend.”

“London Landscapes has been our landscape architect for 22 years at our home in Chevy Chase. They have designed our property through multiple phases, gradually turning a neglected lot into a showpiece featured on garden tours. They did a wonderful job with the gardens but also with terraces, patios, planting beds, a pergola and a fish pond. They are very responsive and also quite cost-effective compared to bigger outfits.

“Working with Barbara was an extraordinarily wonderful experience, and I think it may be a tie between how beautiful the garden she created for me looks and how much I loved working with her. Her incredible creativity, warmth, and kindness along with the ease of working with her makes me love not only my garden but my memory of creating it. Barbara has also been available for any follow-up questions and plantings that I have requested. I can’t imagine a stronger recommendation than I can give for Barbara. Feel free to join the many who stop by front my yard to admire my garden.

We hired London Landscapes as part of a very large multi-year home renovation project. Over the years, Barbara has transformed our outdoor spaces to be visually beautiful and exceptionally appealing in terms of sound and fragrance as well. Creative design, attention to detail, and knowledge of hardscape as well as plants of all types are aspects of London Landscapes unequaled in the local professionals. Barbara is highly personable and terrific to work with as well. She has always listened to all of our thoughts and concerns, and worked diligently to actualize each of our requests. She is very honest about budget and time frames too.”

“Barbara was a great listener when we began the process of a major front garden renovation. We wanted a deer-resistant evergreen but also colorful garden. Her experience and expertise were obvious from the start. She presented us with 3 equally appealing plans one of which we chose to adopt with some modifications. She and her contractors were efficient and the job got done even quicker than we expected. A pleasure to work with from start to finish. Even from the start we had an amazing front landscape and now 3 years later it has matured beautifully.

– Robert V.

Barbara turned our overgrown, tired yard into a space that has become our favorite “room” in the house. She listened carefully to our objectives, and combined them with her own vision for what our garden might become. Barbara was tirelessly engaged throughout our entire project, and kept us on budget too. She is a pleasure to work with, and we recommend her without hesitation.”

– John S, Bethesda MD

“I have relied on Barbara’s services for the past twenty years, including her complete redesign of both the front and rear yards of my home. Her work covers the gamut from landscape design to hardscape installation to full planting. I can’t imagine anyone knows more or cares more about plants and flowers than Barbara. She owns her projects. More important, she’s a total delight to work with – listens carefully to what you’re looking for but able at the same time to steer you towards even better possibilities and away from your bad ideas. A sales person at an outdoor store on seeing a picture of my rear yard recently told me that it was the most beautiful back yard she had ever seen. All that credit goes to Barbara!

– William H.

Barbara is the consummate professional. She turned my front and back yards into fabulous gardens. She worked with me from the earliest design stages to full implementation…and has cared for my garden for over 10 years. It is a joy to work with her and her team!”

“We have worked with Barbara Katz intermittently for the past 20 years. She is an exceptional landscape designer who transformed our property, both hardscape and plantings. Our backyard has been quite a challenging project with a steep hill, erosion, deer and drainage problems. Barbara attached each issue with expertise, resources and innovative solutions, ultimately creating a beautiful garden for us to enjoy. She is hard-working and brings her impressive knowledge, dedication and integrity to her projects. She is a dedicated professional who is delightful to work with and we can’t imagine trusting anyone more.
