Porque Es Trankilo

Harmony is a great local business. Love how my lawn always looks after they come by.

Cannot recommend Harmony Landscaping enough! Ronnell was so knowledgeable, easy to work with, responsive, and a true expert at his craft! We will be lifelong clients after this experience!

Harmony Design came out and provided a free quote and creative ideas for my outdoor house living space. Their unique blend of landscape and architectural ideas made it easy to envision my new backyard.

Marc and team did a great job following our home renovation by designing and installing an upgraded landscaping, hardscaping and drainage plan. Everything looks beautiful and functions perfectly. Thanks again!

Last year we worked with Marc and his team to renovate our patio- and install drainage because we touch on a flood zone. Last night our entire section was flooded- but the drainage in our yard was so perfect we had no standing water- it was amazing! So my absolutely beautiful backyard that they designed for us was completely intact. I can't thank them enough for not only the design and installation but for ensuring it was done right and we now have the proof. I would highly recommend!

Marc is a talented designer and contractor. We could not be happier with our back yard transformation. He helped create a beautiful space with a gunite pool as the centerpiece.

He provided the design, but ways flexible to incorporate some of our ideas. I would absolutely hire Marc and his team again.

We love working with Marc and the Harmony Design Group!
They have been doing beautiful projects incorporating Soake Pools and we can't wait to continue this partnership!

Fantastic company to work with. We have worked with this company for many years. Beautiful design and landscapes.

Working with Harmony Design Group is such a pleasure! Their keen sense of design, excellent customer service and their experience installing our plunge pools provide a next level customer experience, both during the project and after completion. We highly recommend them!

Harmony Design Group is extremely professional. We have worked alongside the team on several projects and the communication, work flow, and end product are all seamless!

Harmony Design Group redesigned our back yard in 2023, and it was one of the best experiences we have ever had with a contractor. At every stage from planning to demolition to installation, they are experienced professionals. They control all parts of the job and complete the work quickly and efficiently. The best part was the design. We never would have conceived of the plan Marc created for us, and it has given us a tremendous amount of joy from the day it was installed. We enjoy the yard whether we are outside or inside the house, because of the thoughtful way he designed the highlights of the landscape to be visible from and complement our indoor spaces. They are very flexible in both the planning and installation. They have an experienced work crew and state of the art equipment that saves you money on labor and reduces the disruption to your property. Marc’s choices of plants has worked out very well for us and becomes more beautiful every year. They also offer maintenance programs - we hire them once a year to come out and do any necessary maintenance on hardscapes and the planting beds - and they stand behind their work. I recommend this company without reservation.

Marc and his team are one of the best in the business. We have worked with them for several years and their work is impeccable.
I highly recommend them for your next outdoor project.

We recently worked with Marc and Harmony to transform our backyard from a muddy swatch of dirt and grass to a hidden oasis that included blue stone patios, retaining walls and an outdoor kitchen. From the very beginning, Marc was attentive and thoughtful in his approach and delivered several potential options for the space. We ultimately went with the vision we loved most and Marc coordinated the bid process for the the job to make sure we found who we were looking for. Every detail was looked after by Harmony from finish selections, coordinating deliveries, various project check-in meetings and ultimately to the final completion. We couldn’t be happier with the end product and are certain you will be too!

Wonderful landscaping company—professional, thoughtful, and reliable. They always go above and beyond to make sure everything looks perfect. Kerri and her team are outstanding. They really go the extra mile to make sure you are getting exactly what you want.

Harmony Design Group planted annuals in the front of my property this year. Kerri and team did a fantastic job. Our property looked so amazing we received multiple notes in our mailbox from neighbors complementing the flowers. Can't wait for HDG's spring annuals to arrive! :)

We had an incredible experience Marc and his team- they transformed our entire property with a stunning design that seamlessly tied together our front yard, backyard, and pool area. Margaret from the design team was especially pleasant and professional to work with, making the whole process smooth, collaborative, and truly enjoyable.

I can’t say enough wonderful things about this landscaping team. They are, by far, the most reliable, thorough, and professional crew I’ve ever worked with. After going through many landscapers over the years, this team has exceeded every expectation. The guys who maintain my property are always friendly, personable, and genuinely take pride in their work.

They show up consistently, pay attention to every detail, and keep my home looking beautiful week after week. Their level of care and commitment is unmatched. This is hands down the best landscaping company I’ve ever used, and I recommend them wholeheartedly to anyone looking for exceptional service.

Harmony Design Group has built an incredible reputation in New Jersey for high-end landscape architecture and outdoor living design. I’ve followed their work and have been consistently impressed by the level of detail, professionalism, and thoughtful design they bring to each project.

Their backyard transformations, retaining walls, patios, and covered outdoor entertainment spaces reflect a true design-build approach. It’s clear they consider grading, drainage, plantings, lighting, and structural integrity from the very beginning rather than treating each element separately.

If you’re a homeowner in Westfield, Summit, Short Hills, Clark, or surrounding Union County towns looking for a landscape architecture firm that values craftsmanship and long-term planning, Harmony Design Group stands out in the New Jersey outdoor living space.

Their portfolio speaks for itself, and their process-driven approach sets them apart from many landscape contractors in NJ.

Highly recommend taking a look at their work if you’re considering a custom patio, retaining wall, or full outdoor living project.

We turned to Marc at Harmony Design Group to help us create our dream backyard—and he absolutely delivered!

From day one, Marc impressed us with his deep knowledge of Westfield’s zoning rules, including ground coverage and building coverage regulations. In a town where property sizes aren’t exactly sprawling, that expertise matters. He knows exactly how to maximize every square inch, and he did just that for us.

He designed a stunning pool, a beautiful outdoor kitchen, and landscaping that flows effortlessly from space to space. The entire yard feels cohesive, intentional, and incredibly serene—truly an oasis and escape right in our own backyard.

In fact, the finished project turned out so beautifully that it was featured in Woman's Day magazine and has since been used as the backdrop for multiple commercial photo shoots—a true testament to his vision and execution.

Beyond the initial design and build, Harmony continues to maintain both our backyard and front yard with the same level of care and excellence through their Fine Gardening department. They refresh our seasonal planters, keep our hydrangeas thriving, and ensure everything always looks manicured and magazine-ready.

Marc is creative, knowledgeable, detail-oriented, and a true professional. I can’t recommend him highly enough.

Very unprofessional, ignores emails and phone calls.
