About Us

Harmony is a design/build firm that brings the best of both worlds to our clients:

Led by landscape architect Marc Nissim, Harmony Design Group is committed to crafting impeccable and totally unique designs from concept to completion.
Why Design/build?
Harmony wants our clients to enjoy the stress-free process of watching their project transform. As a design/build firm we thrive on seeing our initial designs transform into our clients reality. Harmony teams are talented designers, masons, carpenters, electricians, plumbers and laborers; all working together to transition the initial design through to installation and completion.
Our background is organically grounded
Harmony exemplifies modern yet timeless design. We often use classic materials in fresh ways and always look for opportunities to infuse traditional projects with a more contemporary aesthetic.
We love taking the stress out of the process
We are experts in residential landscape design as well as managing the landscape construction process to make your project seamless. Every decision we make throughout the process is in service to our clients and the vision of their project.
We love exceeding expectations
Harmony values the lasting relationships we create with our clients and their input and our years of experience and expertise make our custom crafted designs come to life. We want you to love your outdoor space!
