Frequently Asked Questions
Outdoor Living and Landscape Design Guidance from Gary Duff Designs
Five decades of building outdoor spaces on Long Island have taught us what homeowners want to know before they commit. Here are the answers we give most often.
Fit and Services
-
Gary Duff Designs builds complete outdoor environments and focused single-feature projects across Long Island, from full-property transformations to a single paver terrace or fire feature. Most of our work falls into the complete outdoor living category, where patios, plantings, structures, lighting, and water all come together under one plan. Focused projects receive the same design attention, whether that means a new patio and masonry installation or a poolside seating area. Scope matters less to us than whether the design goals and the property are a genuine fit.
-
The full service list covers landscape design, patios and masonry, outdoor kitchens, pools and poolscapes, fire features, water features, shade structures, plantings, outdoor lighting, and gaming and entertainment spaces. Every one of those elements can be designed as a standalone project or folded into a larger plan. Because the same family manages design and construction, the pieces are planned to work together rather than bolted on later. That coordination is the reason most clients bring us the whole yard rather than one feature at a time.
-
Routine lawn maintenance, seasonal cleanups, irrigation service calls, and repair work on landscapes built by other companies fall outside what Gary Duff Designs does. We are a design-build firm, not a maintenance provider, and we take on select projects starting at $10K. Homeowners looking for a quick fix, a materials-only quote, or the lowest bid on a defined scope are generally better served by a specialty contractor. Saying so early saves everyone the wasted consultation.
-
Gary Duff Designs works throughout Nassau and Suffolk counties from our home base in Holbrook, NY. The heaviest concentration of our work sits along the North Shore in Huntington, Cold Spring Harbor, Lloyd Harbor, Oyster Bay, and Syosset, and east through Smithtown, Stony Brook, and Port Jefferson. We also design regularly in the Hamptons and along the South Shore. If you are unsure whether your town falls inside our range, a phone call sorts it out in a minute.
A Closer Look at Our Services
-
A full outdoor living project covers the entire property as one design, from grading and drainage through the final planting and lighting pass. The plan typically brings together hardscape, a gathering or dining area, a structure for shade, plantings, and lighting so the space reads as a single environment. Gary Duff Designs designs the plan, manages every trade, and builds the project through to completion, which means one team and one point of accountability. Homeowners choose this route when they want the yard solved rather than improved in pieces.
-
A landscape design engagement begins with a property walk and a conversation about how your family actually uses the space, then moves into concept plans and material selection. The design accounts for sun exposure, grade, drainage, existing architecture, and the way you move between the house and the yard. Larger projects include detailed construction plans so the build team works from the same drawings the design team produced. Gary Duff Designs also provides standalone design for homeowners, architects, and builders who plan to construct the work elsewhere.
-
A pergola has an open or louvered roof that filters light, while a pavilion has a solid roof that provides full cover from sun and rain. Louvered pergolas have become the more popular choice among Long Island homeowners because the roof adjusts, giving you shade at midday and open sky in the evening. Pavilions make more sense when the structure needs to protect an outdoor kitchen or a seating area you intend to use in poor weather. Gary Duff Designs sizes and positions every shade structure against the house and the sun path rather than dropping in a stock footprint.
How the Design and Build Process Works
-
The first step is a consultation at your property, where we walk the space, listen to what you want it to do, and give you honest feedback on what the site will and will not support. That visit tells us whether the project is a single feature or a full property plan, and it gives you a realistic sense of scope before any money changes hands. From there, our design team develops concepts, and once you approve the direction, the plan moves into construction documents. Nothing gets built until you have seen and signed off on the design.
-
Every project moves through a design phase before a single stone is set. Depending on scope, that includes concept plans, material boards, and detailed construction drawings so you know exactly what is being built and where. Our portfolio shows how those plans translate into finished properties across Long Island. Revisions happen during the design phase, which is far less costly than discovering a problem mid-build.
-
The Duff family manages the project directly, coordinating every trade, delivery, and inspection from start to finish. That includes the masonry crews setting your patio and walls, the specialty crews handling pool construction, and the electricians running your lighting. You are not left to referee between subcontractors or chase down who is responsible for what. One team plans it, one team runs it, and the same name stands behind the result.
-
Permit filings, zoning requirements, and municipal approvals are handled by Gary Duff Designs as part of the project. Long Island towns vary widely in what they require, and coastal properties add wetlands and setback considerations on top of standard code. After nearly fifty years working across Nassau and Suffolk, our team knows which approvals each jurisdiction requires and how long they realistically take. Building that timeline into the schedule up front keeps the project from stalling later.
Communication and Accountability
-
Each project is assigned a single point of contact from the Duff family who stays with you from design through the final walkthrough. That person knows your plan, your schedule, and your property, so you are never re-explaining your project to someone new. Questions about materials, timing, or changes all go to the same place. Continuity is the reason clients who built with us twenty years ago still call the same number.
-
Questions raised during an active build are answered the same business day in most cases, and always within one business day. Construction schedules shift for weather, inspections, and material lead times, so we tell you when something moves rather than letting you notice it yourself. If a delay affects your completion date, you hear it from us directly. Clear communication about bad news matters more than communication about good news.
-
Changes during construction are documented in writing, priced before any work begins, and approved by you before the crew proceeds. Some changes are simple, such as swapping a paver color or adjusting a planting bed. Others affect structure, drainage, or utilities and carry real cost and schedule implications, which we explain plainly rather than absorbing quietly and surprising you at invoicing. Homeowners who see how a finished project comes together often ask for additions once the space starts taking shape, and that is a normal part of the process.
Built for Long Island Conditions
-
Materials, plants, and structures are selected specifically for salt air, coastal humidity, and freeze-thaw cycles, which are the three conditions that shorten the life of outdoor work on this island. Base preparation and drainage matter more here than material choice, and shortcuts underneath a patio or retaining wall show up as settling and cracking within a few winters. Plant selections account for wind exposure, deer pressure, and the difference between a protected North Shore property and an exposed South Shore lot. Fifty years of watching our own installations age here tells us what holds up.
-
Maintenance load is a design decision, not an afterthought, and Gary Duff Designs plans for the level of upkeep you actually want. Hardscape, lighting, and structures require very little beyond periodic cleaning and occasional sealing. Planting plans drive most of the ongoing work, so if low maintenance is the priority, we weigh the design toward established shrubs, native material, and simpler bed shapes. Telling us that up front produces a very different plan than telling us afterward.
-
Year-round use comes down to heat, cover, and light, and all three are planned during design rather than added later. A fire feature extends the season on both ends by making a patio usable in April and October evenings. Covered structures and motorized screens push that further by handling wind, rain, and insects. Thoughtful landscape lighting is what makes the space usable after five o'clock in the winter months, which is when most homeowners quietly stop going outside.
Investment and Getting Started
-
Pricing is built from scope, site conditions, material selections, and access, which is why two projects of the same square footage can differ substantially. Grade changes, drainage work, and limited equipment access all affect what a project costs before a single finish material is chosen. Gary Duff Designs outlines clear options during the consultation so you can see where the money goes and adjust priorities before committing. You get a real number tied to a real plan rather than a range that moves later.
-
Gary Duff Designs takes on select projects starting at $10K, which covers focused work like a compact terrace, a fire feature, or a garden renovation. Full-property design-build projects involving pools and poolscapes, structures, and complete outdoor living environments represent a considerably larger investment. The consultation is where we determine which category your project falls into. Smaller scope receives the same design attention as larger scope.
-
Financing is available through our partnership with HFS Financial, which specializes in landscape and outdoor living projects. The structure allows homeowners to complete a full project at once rather than phasing it over several years, with fixed-rate payment plans and no prepayment penalties. Most applicants receive funding within 48 hours of approval. Phasing remains an option for homeowners who prefer it, and we design the plan so later phases connect cleanly to the first.
-
Bring a rough sense of your budget range, any inspiration images you have saved, and a survey of your property if you have one. More useful than any of that is a clear picture of how you want to use the space, including how many people you typically host and what time of day you are outside. Gary Duff Designs uses that first meeting to listen and give honest feedback, not to sell you a package. Call 631-737-4229 or submit the contact form to schedule a walkthrough of your property.
