Built into the Hill, Not on Top of It
A hillside pool is fundamentally a structural problem before it is an aesthetic one. The land it sits on is moving, slowly, in directions and at rates that vary with the season, the soil composition, and the seismic conditions specific to the site. A pool built on that land must remain perfectly level across all of it, hold its tile lines and coping details unbroken across decades, and resist the ongoing forces of gravity, hydrostatic pressure, and tectonic movement without showing any of them on the surface. Drummond hillside pools are designed from the ground down, with the structural engineering preceding the aesthetic design rather than the other way around, and built into the slope rather than perched on top of it. The visible pool is the final and easiest part of the project.
An Endless View
Hillside pools offer the opportunity to create a visual unlike any other
Built For Any Grade
With over four decades of experience, the Drummond & Sons team can craft your perfect outdoor living area regardless of slope
Below Grade
A Drummond hillside pool begins with excavation and structural work that often extends ten to twenty feet below the visible pool itself.

Anchored Deep
Where the soil conditions demand it, the structural foundation is tied into bedrock or stable substrate through engineered piers, caissons, or tiebacks.

Built to Move
Drummond pools are both designed and engineered to accommodate the seismic and seasonal movement of Bay Area hillsides.
What a Hillside Pool Makes Possible
The reason to build a pool on a hillside, rather than on the flat portion of a property, is almost always the view. A hillside pool can sit at the edge of a slope rather than in the middle of a lawn, can read as floating above the valley or the Pacific or the city below, and can transform a property's most dramatic feature from something to look at into something to live alongside. Pair the structural work with a vanishing edge, and the water itself dissolves into the landscape beyond it. Frame the pool against a glass-forward modern home, and the architecture extends visually into the slope. The engineering exists to serve the moment when a client steps into the water and realizes that the Bay Area itself has become part of their backyard.
Framing the View
A hillside pool sits at the edge of the slope rather than in the middle of a yard, placing the water itself between the house and the horizon, so the view becomes the backdrop to every swim.
Vertical Drama
The grade change that makes the site difficult to build on is also what makes it remarkable to look at. A hillside pool turns the slope into a feature of the property rather than a constraint on it.
Architecture Extended
Paired with the modern Bay Area home, a hillside pool reads as a continuation of the architecture into the landscape, with the horizontal line of the water carrying the design language of the house out into the slope beyond it.

A Tradition of Building
Drummond & Sons has built hillside pools across the Bay Area for the better part of four decades, on properties that other builders walked away from, on grades that required structural review at the municipal level, and on sites where the geotechnical work alone took weeks to complete before construction could begin. The accumulated knowledge from those projects shows up in every new one, from the early conversations with the client's architect to the final inspection signoff from the county.
Designed with the Architect, Not After
A hillside pool is almost never an isolated project. It sits alongside a home that has been carefully designed for the same property, with its own architectural language, its own relationship to the grade, and its own decisions about how to engage with the view. The Drummond design and engineering team works directly with your architect from the earliest concept phase, with the pool's geometry, edge treatment, and structural strategy developed in concert with the home's footprint, glazing, and outdoor living spaces rather than fitted into the design after it has been completed. The work is collaborative by default and substantially less stressful than the pool-after-the-fact alternative most clients have heard about from friends.

To Live Above the Bay
A pool built into a hillside changes the way the property is used across the seasons. The view, which was previously framed by the kitchen window or the back deck, becomes something you swim into. The light, which falls differently across a slope than across flat ground, animates the water through the course of the afternoon and evening. The boundary between the house and the landscape softens, with the pool sitting as the visible threshold between the two. Most Drummond hillside clients describe the same shift in the first year of ownership, that the pool is not so much a feature on the property as the new center of how the property is lived in.
