One of the most common questions we hear from Long Island homeowners is: "How much does landscape design cost?" The honest answer is that it depends on several factors — but this guide will give you real numbers, explain what drives cost up or down, and help you understand exactly what you're paying for when you hire a professional landscape designer on Long Island.
Landscape Design Fees on Long Island: The Real Numbers
Professional landscape design fees on Long Island typically fall into these ranges:
| Scope | Design Fee Range | What's Included |
|---|---|---|
| Garden Refresh (single area) | $1,500 – $3,500 | Site visit, concept plan, plant list |
| Full Property Design | $3,500 – $8,000 | Site analysis, 3D renderings, full plant specification |
| Estate / Large Property | $8,000 – $20,000+ | Multi-phase master plan, drainage, lighting, hardscape coordination |
| Design-Build (design + install) | Design fee often waived or credited | Full design + installation by same firm |
These are design-only fees — the cost of the plan itself, not the installation. Installation costs are separate and depend on the scope of work, plant sizes, and site conditions.
What Affects Landscape Design Cost on Long Island
1. Property Size
The most obvious driver of design cost is how much ground needs to be covered. A quarter-acre property in Commack requires significantly less design work than a two-acre estate in Sands Point or Brookville. Larger properties require more site analysis, more detailed planting plans, and often multi-phase installation schedules.
2. Design Complexity
A simple front yard refresh with foundation plantings and a few specimen trees costs less to design than a full backyard transformation incorporating a pool surround, outdoor kitchen, multiple planting zones, privacy screening, and a lighting plan. The more elements that need to be coordinated, the more design time is required.
3. Whether You Use a Design-Build Firm
Many design-build firms on Long Island — including Cardi Design & Build — either waive the design fee entirely when you proceed with installation, or credit it toward the installation cost. This means you effectively get the design for free when you commit to the full project. If you hire a design-only landscape architect and then take their plans to a separate contractor, you'll pay the full design fee plus the contractor's markup.
4. Level of Detail in the Design
A basic concept sketch costs less than a fully detailed design package with 3D renderings, a complete plant schedule with botanical names and sizes, a grading and drainage plan, and a phased installation timeline. The more detailed the design, the more it costs — but the more detailed the design, the fewer surprises you'll encounter during installation.
5. Site Conditions
Properties with challenging conditions — steep slopes, poor drainage, heavy shade, sandy coastal soil, or proximity to wetlands — require more analysis and more creative problem-solving. This adds time to the design process and increases the fee accordingly.
What Does Landscape Installation Cost on Long Island?
Installation costs vary widely depending on what's being installed, but here are realistic ranges for common landscape projects on Long Island:
| Project Type | Typical Cost Range |
|---|---|
| Foundation planting refresh | $3,000 – $8,000 |
| Full front yard landscape | $8,000 – $25,000 |
| Backyard planting & privacy screening | $10,000 – $40,000 |
| Full property landscape installation | $25,000 – $100,000+ |
| Estate landscape master plan (multi-phase) | $75,000 – $300,000+ |
These ranges reflect Long Island market pricing as of 2025. Costs have increased significantly since 2020 due to plant material shortages, fuel costs, and labor market conditions. Projects in the Hamptons and North Fork typically run 15–25% higher than comparable projects in Nassau County due to travel time and local labor costs.
Is Professional Landscape Design Worth the Cost?
In our experience, the answer is almost always yes — for several reasons:
Avoiding costly mistakes. The most expensive landscape projects we've seen are ones where homeowners planted without a plan, then had to remove and replace plants that were the wrong size, wrong species, or in the wrong location. A $3,000 design fee is far less expensive than $15,000 in removal and replanting.
Seeing it before you build it. 3D renderings allow you to make changes on paper — which costs nothing — rather than in the field, which can cost thousands. Clients who see their design in 3D before installation almost always make at least one significant change that improves the final result.
Return on investment. A well-designed landscape adds 10–15% to property value according to most real estate studies. On a $1.5 million Long Island home, that's $150,000–$225,000 in added value from a landscape investment that might cost $50,000–$75,000.
Phasing flexibility. A complete landscape design plan allows you to phase the installation over multiple seasons or years, spreading the cost while working toward a unified vision. Without a plan, phased projects often look disjointed.
