Landscape design and master planning in the Hamptons: 2026 fees, and the RLA question nobody explains
Hamptons landscape design typically runs 5–20% of the construction budget as a fee (10–15% is the most common range), or flat fees from about $2,200–8,000 for a standard residential project up to $15,000–30,000+ for a large estate; hourly rates span $50–275+ depending on experience. No design-build firm we checked, including ones headquartered in Bridgehampton, publishes a fee figure anywhere — every one routes to a consultation. New York licenses the title "landscape architect" (NY Education Law Article 148); it does not require a license to design a garden.

What this covers
A master plan lays out the whole property: grading, drainage, planting zones, hardscape, screening, sometimes a pool surround or a court. A landscape design can be narrower — a planting plan for one part of the property. Both are design work, priced differently from installation (see Planting Design & Installation) and differently again from ongoing care.
Landscape architect, or landscape designer
New York State licenses the title "landscape architect" under Education Law Article 148 (§§7320–7328). Getting there needs a combined education-and-experience score of at least 12 units (an accredited four-year degree is worth 8, a related graduate degree can add more) plus passing the LARE exam administered by CLARB. What the license actually gates, under §7321, is narrow: consultation and design for land preservation, planting, grading and drainage — explicitly not structural design, which stays with architects and engineers.
What the same law does not do is ban anyone else from doing landscape work. Under §7326, "landscape designer," "landscape gardener," "horticulturist," "nurseryman," "arborist" and "contractor" are all legal, unlicensed titles. Most residential planting design in the Hamptons is done, entirely legally, by people who hold one of those instead of an RLA license, typically for $400–3,000 on a planting-focused job.
Two towns disagree, in their own paperwork, about when the license actually matters. East Hampton Town's site-plan application instructions (revised April 2025) name a licensed architect or engineer for floor plans and a licensed land surveyor for the site plan itself — a landscape architect is never named as an acceptable sealer of anything, and the landscaping plan itself needs no professional seal at all. Southampton Town's own application form (revised January 2025), by contrast, names "Licensed Architect, Landscape Architect, Civil Engineer or Land Surveyor" as acceptable preparers of a site plan that includes landscape and grading plans. Which town you are building in changes the answer.
What it costs (2026)
| Fee structure | Range |
|---|---|
| Percentage of construction cost | 5–20%, with 10–15% the most commonly cited center (sources disagree; do not average to one number) |
| Worked example | 10% fee on a $35,000 project = $3,500; 15% fee on a $400,000 project = $60,000 |
| Hourly, entry (0–2 yrs) | $50–65/hr |
| Hourly, mid (3–7 yrs) | $75–100/hr |
| Hourly, senior (8–15 yrs) | $100–125/hr |
| Hourly, principal / licensed 15+ yrs | $125–275+/hr |
| Flat fee, small urban garden | $500–2,000 |
| Flat fee, standard residential | $2,200–8,000 |
| Flat fee, large estate | $5,000–20,000 |
| Flat fee, luxury / complex | $15,000–30,000+ |
| National median (one source) | $4,200 |
| Unlicensed "landscape designer," planting-focused | $400–3,000 |
| Deposit | Flat (e.g. $3,000) or 25–35% upfront; larger jobs sometimes 25–50% plus $2,000–5,000/month project management |
At Hamptons-scale budgets, the 10–15% center works out to roughly $5,000–7,500 on a $50,000 project, $15,000–22,500 on $150,000, and $40,000–60,000 on $400,000 — arithmetic, not a quoted figure, since no Hamptons-specific percentage has been published anywhere we found.
The Suffolk / East End numbers
One East End source (dated 2026-08-27) frames whole-project tiers rather than design fees alone: a small project $5,000–8,000, a medium one with retaining walls, drainage and beds $10,000–22,000, a full yard renovation $25,000–75,000+, and a design fee alone $2,000–10,000, framing Suffolk County as running 30–60% above a national reference of $3,500–8,500, with labor at 40–65% of total cost. A Long Island design-build company's own blended tiers: a simple project (small patio plus some landscaping) $15,000–35,000, an "outdoor living room" $25,000–75,000, a full-property transformation $150,000+. As a rule of thumb, one source suggests budgeting 5–10% of home value — $50,000–100,000 on a $1M property.
The process, in phases
Where a phase breakdown exists: site analysis 10–15% of the total fee, concept design 20–25%, design development 25–30%, construction documents 25–30%, with construction-phase oversight often billed separately, frequently hourly even when the design itself was a flat fee.
What we have not found
No Hamptons or East End-specific design-fee figure exists anywhere we could locate — three local design-build firms, including ones based in Bridgehampton, were checked directly and every one routes a fee question to "request a consultation." ASLA, the industry's own professional association, confirms it publishes no client-facing fee guidance at all. We print the honest national and regional ranges instead of inventing a local number.
FAQ
Common questions
How much does a landscape master plan or design cost in the Hamptons?
It is billed either as a percentage of the construction budget, 5–20% with 10–15% the most common range, or as a flat fee: roughly $2,200–8,000 for a standard residential project, $5,000–20,000 for a large estate, and $15,000–30,000+ for a luxury or highly complex one. Hourly rates run $50–65 for junior staff up to $125–275+ for a principal or licensed landscape architect. No design-build firm we checked, including several headquartered in Bridgehampton, publishes a fee figure anywhere on its own site — every one routes the question to a consultation, and we say so rather than invent a local number.
Read the full answer →Do I need a licensed landscape architect in the Hamptons, or can a designer do it?
Usually not. New York licenses the title "landscape architect" under Education Law Article 148, but the same law explicitly makes "landscape designer," "landscape gardener," "contractor" and "arborist" legal, unlicensed titles, and most residential planting design is done by people holding one of those. Where it actually matters is paperwork: Southampton Town's site-plan form names a landscape architect as an acceptable preparer; East Hampton Town's current instructions never do, and require no professional seal on a landscaping plan at all. Which town you are building in decides whether the license buys you anything on the permit itself.
Read the full answer →How does Bridgehampton Gardens work, and what does it cost me?
It costs homeowners nothing. You tell us, in about sixty seconds, whether you need design (a master plan or a planting design) or care (maintenance, cleanup, irrigation, deer fencing) — that first answer is the whole funnel. We put you in touch with one licensed, insured landscape pro who works your town and does that kind of work, and they call you within one business day. We are a Hamptons-only referral service, not a landscape architecture, design or maintenance company, and we are not connected to any garden, nursery or landscaper of a similar name. Participating pros pay us a referral fee.
