We’re proud of the reputation we’ve earned through years of collaborating with renowned custom home builders and architects to build luxury landscapes. Our relationships with landscape architects in the area mean everything to us and the work we do. A crucial part of a successful project is making sure you have the right team from the start.

OUR MATERIALS

We’re proud to operate and offer a wide variety of material from locations throughout Massachusetts. Here is our full list of materials offered.

To get in contact with us, please email materials@onyxcorporation.net
Homeowners should begin by discussing their ideas with Onyx, leveraging our deep knowledge of the field and our industry contacts; Onyx works with a select group of landscape architects and can offer guidance on finding the right fit for your vision.
Once a schematic design is complete, Onyx works with homeowners to meet with contractors, compare options and review details. Onyx then collaborates with you, the landscape architect and our preferred vendors to value engineer our design and provide final pricing that aligns with your budget. Our team will then spearhead the engineering and permitting process in order to secure required permits.
Permits in hand, we can mobilize and excavation can begin. Onyx will guide you step-by-step through the landscape construction process—ranging from gunite pools and plumbing to patios, lawn and lighting, and then to the fun, final step, enjoying your outdoor space!
During this process, Onyx’s full-service team will be onsite, building the landscape of your dreams; including fire features, outdoor kitchens, walkways, retaining walls and plantings. Bringing these elements to fruition can occur simultaneously, and having the right team in place is essential for coordination and efficiency.
Now that you are ready to enjoy your new landscape, the last consideration is upkeep. With your new team in place, Onyx will oversee the transition from construction to maintenance. Your landscape will be carefully maintained, ensuring the success and longevity of your own personal paradise.
