For more than 35 years, Harold Leidner Landscape Architects has custom-designed and built exceptional pools, gardens, and outdoor living environments for discerning homeowners in Highland Park, University Park, Preston Hollow, Dallas, Fort Worth, Westover Hills, and Westlake.

From the beginning, our belief has been simple: the designers who conceive an exterior should be the ones who build it. Like architects, licensed Landscape Architects are trained to unite aesthetics with construction detail, so we lead every phase, from concept to construction completion and long-term concierge care. This is why every one of our designers and project managers are required to be a certified Landscape Architect.

We do not sell our plans to outside contractors. We do not take a fee to manage teams we didn’t hire. We design, build, steward, and guarantee our work-end to end. When on-site questions arise (and they always do), the design lead is present to answer them, protecting intent, quality, and longevity.

This integrated approach produces exteriors that are beautifully curated and functionally sound: materials chosen for durability, systems planned for efficiency, and environmental decisions made with the guidance of our years of experience and delivered through a single, accountable source.

While technology enhances our process, our ideas still begin the timeless way: with a pencil and a roll of trace paper.

When it’s all said and done, a Harold Leidner exterior is more than beautiful-it’s iconic.
