Dallas Landscape Architecture

Your Outdoor Space,
Designed With You
Every Step of the Way.

Most firms hand you a beautiful drawing and disappear into the build. We meet with you every single week — from first concept to final stone — so the space you get is exactly the one you imagined.

Most firms disappear
after the drawing.

You've seen it happen. Beautiful renderings. Then a build that goes sideways — and a designer who's nowhere to be found.

  • You receive beautiful drawings — then spend months coordinating between the designer and multiple contractors yourself.

  • Design intent gets lost in translation. What was on paper and what gets built are two different things.

  • There's no continuity after construction — no one to steward the landscape through the seasons that follow.

  • You're left managing multiple vendors with no single point of accountability when something goes wrong.

"Design doesn't stop when the pencil gets set down. That's why we meet with our clients every week to walk through ideas, make decisions together, and fine-tune every detail."

How a Harold Leidner
project actually works.

No mystery. No surprises. Here's exactly what to expect from your first call to the day construction wraps.

01

Align on Vision & Priorities

Every project begins with a conversation. We take the time to understand how you want to live outdoors — what you want to feel, how you gather, and which elements matter most to you.

02

Shape the Property

We thoughtfully organize the landscape from the ground up, establishing pool placement, outdoor living spaces, circulation, and grading to create a cohesive and effortless flow.

03

Refine Every Detail

From materials and finishes to lighting and plantings, we guide each decision with intention — thoughtfully considering each element to create a landscape that feels intentional, elevated, and complete.

04

Build with Care & Oversight

From coordinating trades to managing schedules and daily decisions, we handle every detail — allowing you to feel at ease knowing your project is being built with care, precision, and intention.

05

Steward with Continuity

Our commitment continues long after completion. Through our Concierge Maintenance program, the same team that designed and built your landscape remains involved — nurturing its growth, refining seasonal details, and preserving its beauty for years to come.

What our clients
say after the build.

Harold Leidner worked on our front and backyard. They did an exceptional job from start to finish. They walked us through the scope of the project and kept us updated throughout with any changes and updates. They handled turf, sprinklers, new plants, pool, outdoor kitchen, driveway, and patio tile. If any issues happened during the project the entire team was on it to find a resolution and get it fixed. This is a professional company and I highly recommend them to anyone. You will be in good hands.

I was very pleased with our experience with Harold Leidner and his landscape team. We have used Harold's services on our last two homes, and although we are not anticipating another move, we would use Harold again if the opportunity presented itself.

Mr. Troy Aikman — Dallas, TX

Our best projects are the result of a successful collaboration between owner, architect, interior designer, and landscape architect. Harold's creative landscape designs consistently enhance the setting and the architecture of a home. We highly recommend Harold and his team to anyone who appreciates the importance of well thought out and detailed landscape design. Harold has every last detail in mind. He is efficient, gets his work done on time and is good with clients!

Everything you want to
know before we talk.

Do you offer both landscape design and installation?

Yes. We are a fully integrated Landscape Architecture Design-Build firm. Our licensed landscape architects lead the creative vision, while our in-house construction and horticulture teams execute every detail with precision, ensuring design integrity and quality craftsmanship from concept to completion and beyond.

What makes Harold Leidner different from other landscape companies?

We provide a white-glove, end-to-end experience from initial design through construction and continuity of long-term maintenance. We have distinct accolades that make us unique: Multi Award-Winning Landscape Architecture, High-Touch Project Management, In-House Concierge Maintenance, and One Dedicated and Trusted Point of Contact for all your exterior landscape needs.

What does your complimentary consultation include?

A licensed Landscape Architect meets you on-site to walk the property, discuss goals and constraints, and outline opportunities. You'll leave with initial concept ideas and recommended next steps (no drawings at this stage).

What areas do you serve?

We work throughout the Dallas–Fort Worth Metroplex and surrounding luxury residential neighborhoods — including Highland Park, Preston Hollow, University Park, Park Cities, Westover Hills, Vaquero, Lakewood, Westlake, Southlake, Frisco, Celina, Fort Worth, Prosper, and more.

How much does a new landscape design project cost?

Overall project budgets reflect the level of customization, site conditions, and amenities such as pools, pavilions, lighting, recreation, and irrigation. Typical projects range around 15–20% of your property's total value. We provide preliminary budgets and phased implementation during the early stages of design to guide decisions.
