20+ Years
BS Ornamental Horticulture
5-Year Hardscape Warranty
A look at what we've been building across Central New Jersey, Bucks County Pennsylvania and the surrounding area.
Designed. Built. Maintained.
What We Build
Whether you're starting with a sketch on a napkin or a fully-developed plan, we design and build the whole project under one roof.
Hardscape & Outdoor Living
Patios, walkways, outdoor kitchens, fire features, retaining walls, pergolas. Bluestone, paver, natural stone — built to last with a 5-year warranty.
Landscape Design
Detailed 2D and 3D plans, native plantings, pool integration, drainage, and grading. Designed and stamped by an owner with 30+ years in the field.
Plantings & Garden Installation
Trees, shrubs, perennial beds, native plantings, sod, and seasonal color. Selected and placed for the soils and climate of Central NJ — not from a generic plant list.
Estate & Property Maintenance
For homeowners who want one team caring for their property year-round. Mowing, pruning, fertilization, snow management, and seasonal cleanup — coordinated by a single point of contact.
Pool Design & Renovations
For homeowners who want one team caring for their property year-round. Mowing, pruning, fertilization, snow management, and seasonal cleanup — coordinated by a single point of contact.
One team, design through maintenance
You're not coordinating a designer, a hardscape crew, a planting subcontractor, and a maintenance company. We do all of it, with one project manager, one warranty, and one phone number.
The owner is on the job
Rich Green founded DELIS in 2009 after two decades in the field. He visits every active jobsite. The crew has been with him for years — no churn, no subcontractor surprises.
Built for what New Jersey does to a yard
Frost heave. Heavy clay soil. Saturating spring rains. Our hardscape installs are engineered for Mercer County, not for a YouTube tutorial. Every install gets a 5-year warranty.
Plant-led, not pattern-led
Our owner has a Bachelor of Science in Ornamental Horticulture. We design with native plants that thrive here, and we tell you when a planting choice you've seen on Pinterest won't survive a Pennington winter.
How It Works
From first call to finished install, here's the process. No surprises.
Free Consultation
Call us or fill out the quote form. We'll set up a free on-site visit, walk your property, and talk through what you're trying to accomplish. No pressure, no pricing yet, just listening.
Design & Proposal
For projects over $20K, we develop a 2D or 3D design so you can see the finished space before we break ground. You get a detailed proposal with materials, scope, timeline, and price, itemized.
Build & Warranty
We schedule the build, manage permits, and stay in touch through every phase. Hardscape installs come with a 5-year warranty. Plantings come with a 1-year warranty. We're still around in year 12 if something needs us.
