Harmony Design Group recently completed our complete backyard renovation and we could not be happier! Our backyard has truly reached its potential. Marc and his team were always easily accessible and responsive. We were so happy with their initial plan all the way to completions we cannot wait to enjoy our new outdoor space for years to come!

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!

We hired Harmony Design Group to do a large project for our new home. This included landscaping the front and back of the property and also lighting. From our first meeting with Marc Nissam, we knew he was the right guy for the job. Marc was patient, diligent and professional throughout the scope of the job. He finished ahead of schedule and we are so pleased with the end result. His creativity and knowledge for landscape design really did put the finishing touches on our new home. We would highly recommend Marc Nissam and HDG!!

I have been a homeowner in Westfield for 25 years. I can unequivocally state that Marc (HDG) is the most knowledgeable and accomplished landscape designer whom I have ever worked with.
He has amazing vision to look at a property and either create or transform it into the most visually appealing result.
I thought that I had a nice looking manicured pool/patio/yard until Marc renewed it into a more elegant, appealing property. What's more, he had initially inspected the property at the end of the winter
at a complete disadvantage regarding light/growth etc, and yet was able to 100% perfectly recommend the ideal plantings for the property predicting to the month when we would have the color blooms and growth which he had advised. Gentle lighting was added around the whole property and we are beyond satisfied. The HDG affiliated crews were polite, diligent and professional. You must consult Marc for his expert advice.

Hi. Marc came to our home. Spent a hour with us. He promised an estimate for doing a landscape design. It has been four weeks and he has not sent anything or called. I would not recommend him.

Comment from Harmony Design Group:
Sorry for not following up on the meeting we had at your home. The month of May is the busiest weeks of the entire season. We take a tremendous pride in the quality of service we provide our clients but it is a difficult to balance servicing the clients we are already working for and new potential clients during this time of year. We would like a chance to discuss this matter in more detail with you. Please give our office a call or email me direct.

We hired Marc with a tight deadline to redo our yard for our daughter's Batmitzvah. He succeeded and did a beautiful job. We were very pleased.

We have had the pleasure of working with Marc and his team for the past few years on projects together. Marc is alway professional and respectful of our clients dreams. His creativity and talent during the design process and equally as talented leading his team during the construction process, always fine the right solution to the project. As an architect, its important to have a landscape team that can execute the landing of our projects beautifuly.
We recommend Marc Niesham and his team highly. He is a pleasure to work with.

My wife and I recently moved into a penthouse with two large fenced in but bare roof top garden areas, and a large balcony overlooking the city. We contracted with the Harmony Design Group to open up these areas. With his first drawing, Marc capitalized on the perfect design for the gardens and balcony. Working with his team they installed panels to cover the fences, planters, plants, sprinkling systems, benches, flooring, lights, lanterns, a statue and a fountain. The results are spectacular, and visitors view the gardens and balcony as the highlight of our home. We are indebted to Marc and his team for bringing their expertise into our lives.

I was glad that I chose this Chose Marc Nassim for the Land Scraping Architect. He was very responsive and did a FANTASTIC!!! Job. I highly reccomend Architectural services before you bid out your Job as every Hard Scape Contractor will give you quote according to their design and product. His response was prompt when we had a problem at site and he came over right away so that the project won't get delayed.

I have used Marc for landscape designs since 2013 when my good friend Matt Rusk of Rusk Enterprises referred him to me. Marc's first design for me was an exceptional landscape design to the entrance of my clients home in Denville NJ. His plan encompassed a full season of color, from constants such as boxwood's, to the vivid bloom of iris' to the perennial grasses which created a soft texture and turned with the fall months.
Several months later I met Marc out on a large project shooting elevations for a grading plan. Marc is one of the few who landscape architects who is not afraid to get dirty, he truly has field experience. He's not just behind a desk pumping out a million designs a season with little thought or care. His ability to capture a person's dream and add his own creativity produces a final design that is second to none.
I will be using Marc's firm for years!

I own a Landscape Contracting firm and started using Marc for my Landscape Designs in 2009. 6 years later I am still using Harmony Design Group because Marc is consistently able to turn out innovative designs of the highest quality. Marc is one of the only Landscape Architects I have met that have a lot of hands on field experience. That helps him design projects that are actually build able. Field experiences is the most important asset any architect can posses.
Many Landscape Architects are only masters of one area of the Landscape. Not Marc. Marc is knowledgeable in all areas of Landscape Architecture: from grading, to masonry, to custom swimming pools, horticulture and landscaping lighting. Marc can design it all and that makes him the total package when it comes to innovative landscape architecture. I see my firm working with Marc and Harmony Design Group for many years to come!

Marc and his crew did an amazing job on transforming the severely neglected yard of our new house into a thing of beauty. He worked with me every step of the way and was great at listening to what I wanted, putting it to paper, and then executing it just as I had imagined. In addition, he worked with me in order to get me as much as he could within my limited budget. His crew was extremely professional as well as speedy! Once the design part of the process was over and the transformation was underway, I was amazed at how quickly it got completed. We've already received numerous compliments from neighbors and friends. I would definitely recommend Harmony Design Group and will be using them for the next phase of our project when we get there.

I have worked with Marc on numerous projects over the past 9 years. Marc's landscape architectural skill is excellent. I love his ideas. I love his plant selection. He is exceptional at figuring out unique design ideas for each client and each site. Throughout the entire design process with Marc, he makes the process fun and easy.
In addition, Marc's rendering abilities are top-notch. He excels at not only creating beautiful 2D landscape plans, but he also creates exceptional 3D renderings on SketchUp. I highly recommend Marc to anyone interested in landscape architectural services.

From start to finish, Marc Nissim (Harmony Design Group) exceeds expectations. He has a gift for transforming outdoor spaces into beautiful living areas…he is creative, smart and importantly, has extensive supplier relationships that he puts to work for you. Using these assets, he turns your outdoor space into a seamless extension of your home.
Two years ago my husband and I purchased a property in Westfield, New Jersey. The home and property were severely neglected and needed complete renovation. Having done renovations in the past, we knew it was important to have the house and landscape integrated. We wanted to hire a Landscape Architect at the very beginning of the project to be a part of the design process, along with the Architect, General Contractor, and Interior Designer. After interviewing several Landscape Architects, we found Marc, owner of Harmony Design Group to be exactly what we were looking for. Not only did he have an extensive portfolio and resume, but he was clearly passionate about his craft. He was also a key member of the construction team from start to finish.
During the design process, we were completely impressed with Marc’s extensive knowledge- base of landscape architecture. Further, his collaborative approach to design helped blend our tastes and preferences into the overall plan. We had no idea how complex landscape architecture really is! The science behind a successful landscape involves grading, proper drainage, an irrigation system, patios, proper balance between flowering and evergreen shrubs and trees, which have to be properly sequenced…the whole thing really must be just right!!
Finally, when it came time for the landscape installation, Marc assembled a customized team of professional contractors that also exceeded our expectations. He managed his vast network of suppliers to deliver their best within the timeline and budget of the overall project.
Marc’s well-seasoned project management skills really became evident during the last few weeks of the project. With a strict timeline for completion and a congested job site, we were confident that the project would be completed to our expectations. He was able to deliver a stunning, yet personal design on time and within in our budget.
I highly recommend Marc and the Harmony Design Group to anyone who wants to love the outside of their home as much as they do the inside.

Marc, owner of Harmony Design Group is the best, a consummate professional! Our project included a new patio and plantings in front and back of our house. Everything looks great! Marc has great design ideas and stays within budget. Our project began right after Hurricane Sandy. I was worried the work would not get done this fall, due to all the damage in our town. We had no power for 9 days, but somehow everything came together. Marc its thoroughly involved in managing the sub contractors working on the project and has great pride in his work.Highly recommend.

I hired Harmony Design Group in June 2012 to plan and install lights on my back patio. I wanted the lights to provide enough visibility on the patio so that we could us it socially during the summer. I was concerned about having lights installed that would give off too much glare for people who were sitting out back. Marc Nissim listened to everything that I wanted to accomplish. He came up with a solution that included installing a soft glow light on the second floor of our house - something I would not have thought of. I was concerned about how this would look. Marc volunteered to bring me to 2 houses that he had installed similar lights on. We visited both houses, which really helped in my understanding of what he thought would be the best solution. Marc took a lot of time to make sure that I was comfortable with everything that he had proposed. The outcome has been excellent. Installation was as non-invasive as I'd have hoped for (i.e., very little disturbance to plants, grassy areas where wires were installed) and the parts used seem to be of high quality. The project was also completed quickly and within budget. Based on my experience, I would highly recommend Harmony to anyone looking to install high quality, well planned and property installed outdoor lighting.
