Westchester is not a uniform building environment. A gunite pool in Bronxville sits on entirely different soil from one in North Salem. Waterfront properties in Rye and Mamaroneck deal with high water tables and salt-air corrosion. Backcountry Bedford, Pound Ridge, and North Salem properties sit on glacial bedrock that requires rock excavation and engineering. White Plains and Chappaqua have glacial clay deposits that demand careful subsurface drainage to prevent shell uplift over time.
A high-end gunite pool builder serving Westchester has to engineer each pool to its specific site — not drop a stock shell into a stock backyard. That's what we do. Every pool we build in Westchester is preceded by a real soils analysis, real survey work, and a structural shell engineered for the property the pool is being built on.
Our Westchester County core service area covers the towns where luxury custom construction is the norm — places where homeowners and architects expect the pool to match the standard of the rest of the property:
Lower Westchester (coastal & near-NYC): Rye, Larchmont, Mamaroneck, Scarsdale, Bronxville, New Rochelle, Harrison, Pelham, White Plains.
Mid & backcountry Westchester: Bedford, Pound Ridge, Chappaqua, Armonk, Katonah, North Salem, Mount Kisco, Pleasantville, Irvington, Dobbs Ferry, Lewisboro, Port Chester.
Every gunite pool we build in Westchester begins with design — and the design begins on the property, with the homeowner and (when there is one) the architect or landscape architect. We walk the site. We discuss sight lines from the house, sun exposure, prevailing wind, the relationship of the pool to other architectural elements (terrace, kitchen, pool house). Then we develop the pool design in coordination with the home's architecture and the landscape plan.
For Westchester specifically, the design phase has to grapple with: Westchester municipal design review boards (more aggressive than CT counterparts in towns like Scarsdale and Chappaqua), waterfront permitting (lower Westchester coast), tree preservation ordinances (most backcountry towns), and HOA design committees (Bronxville, parts of Larchmont, parts of Pound Ridge). We've worked through every one of these. Read more about our pool design process.
The most demanding gunite construction in luxury residential. Water sits flush with the surrounding stone patio, spills evenly over all four sides into a hidden deck slot, and returns to a buried surge tank. The result is a mirror-flat reflecting plane that doubles as a swimming pool. We engineer the hidden gutter, the catch basin, the surge tank, the dedicated pump system, and the precise leveling tolerance required (typically ±1/8 inch across the entire perimeter). Demanded by clients in Bedford, Pound Ridge, and waterfront Rye.
For sloped properties with a view — common in Pound Ridge, Bedford, and parts of Chappaqua. Water spills over an exposed weir into a hidden catch basin, creating the visual illusion of water extending into the landscape beyond. There is no structural difference between "infinity pool" and "vanishing edge" — same architectural design, same hidden catch basin, same balance-tank engineering. We've built dozens. More on our vanishing-edge process.
For homeowners willing to invest in the highest-end finish: full glass-mosaic pool interiors. Hand-set by specialist masons over a properly prepared substrate. Durable through the Hudson Valley freeze-thaw cycle (a real issue for cheaper finishes), color-stable over decades, and architecturally distinct in a way plaster cannot match.
The "Baja shelf" or sun shelf is now a baseline expectation in Westchester luxury construction. We build them as integrated extensions of the gunite shell — usually 6 to 12 inches deep, sized for two patio loungers, often with a bubbler feature or umbrella sleeve cast into the structure. Not an afterthought.
Spa integrated into the bond beam of the pool with a tile or stone spillover into the main pool. Heated independently for year-round use through the Northeast winter. Wired into the same automation system as the pool itself. More on our spa work.
Cover Pools T4 system with a gunite-encapsulated housing at one end of the pool. Tracks integrated under the stone coping. No visible plastic hardware. ASTM F1346 safety-certified, NEC 680 electrical-compliant. More on our automatic-cover work.
The 2026 luxury pool is the architectural anchor of an integrated outdoor space — not a stand-alone item dropped into a lawn. For our Westchester clients, this means the pool design coordinates with terrace levels, with the home's stone or brick palette, with sight lines from interior living spaces, and with the existing or planned outdoor kitchen, pergola, or pool house. We do the pool. We coordinate with the architects, landscape architects, and masonry trades who do the rest. See water features and premium finishing for the coordinating work we do directly.

Building a custom gunite pool in Westchester County, NY generally requires 8 to 12 weeks of active construction. However, when factoring in local municipal permits, architectural engineering approvals, and seasonal Northeast weather delays, homeowners should plan for a total timeline of 4 to 6 months from signed contract to first swim.
A perimeter overflow pool, also known as a knife-edge or zero-edge pool, features water that spills evenly over all four edges into a hidden deck slot. This complex architectural design creates a stunning, mirror-like water surface perfectly flush with the surrounding stone patio.
There is no structural difference; the terms "infinity pool," "vanishing edge," and "negative edge" all describe the same design. In this setup, water cascades over an exposed weir into a hidden lower catch basin, creating the optical illusion that the water surface extends perfectly into the horizon.
A Baja shelf, also known as a tanning ledge or sun shelf, is a large, flat step built into a gunite pool. Usually submerged 6 to 12 inches deep, it provides a resort-style lounging area for patio chairs and a safe, shallow space for children.
Both are applied concrete used for luxury pools, but they differ in application. Gunite is a dry concrete mix propelled through a hose and mixed with water directly at the nozzle for superior structural control. Shotcrete is a wet mix pumped fully hydrated. Gedney Pools pours high-strength gunite exclusively.
Gunite is the only construction method that gives complete freedom of shape, depth, and integrated features such as vanishing edges, raised spas, sun shelves, and custom water features. Vinyl liners need replacement every 7 to 10 years. Fiberglass shells arrive as factory-molded units limited to roughly 16 feet wide due to transport constraints. For luxury residential construction in the Hudson Valley climate, gunite is the only material that combines structural durability with architectural freedom.
