Start With the Property
Access, grade, drainage, existing conditions, and how the space should work shape the plan before materials are selected.
Meet the Owner
I'm Aaron Sandefur, the owner of Custom Landscapes by Design. I have nine years of experience in the landscaping industry, with a background spanning material delivery, landscape design, business operations, project planning, and large-scale residential landscape construction.
My landscaping career began as a 40% owner of Rocky Mountain Precision Services. I initially delivered materials to project sites, giving me direct exposure to the construction process and showing me how material selection, preparation, scheduling, and jobsite coordination affect the final result.
I later moved into landscape design, working with homeowners to plan outdoor spaces around appearance, functionality, drainage, maintenance, and budget. That experience reinforced an important principle: a successful landscape is not simply a collection of individual features. Patios, retaining walls, lawns, planting areas, irrigation, lighting, walkways, and outdoor living spaces must be designed to function together.
During my time with Rocky Mountain Precision Services, I also developed internal office organization systems as the company grew to approximately $6.5 million in annual revenue. That experience gave me a detailed understanding of the planning, communication, documentation, and operational coordination required to manage complex landscaping projects at scale.
Why Custom Landscapes by Design exists
I later founded Custom Landscapes by Design to build a landscaping company centered on thoughtful design, durable construction, fair pricing, and a better customer experience. Since then, our company has completed multiple six-figure landscape projects involving extensive outdoor transformations and several areas of landscape construction.
My Christian faith influences how I approach leadership, responsibility, and customer relationships. I also completed a two-year, unaccredited Christian Leadership program. I believe customers should be treated honestly, communication should be direct, and commitments should be taken seriously.
Our mission
Our goal is to create beautiful, functional landscapes at a fair price and become Colorado's most trusted landscaping contractor. We want every customer to feel confident that their property has been thoughtfully designed, carefully planned, and built around the way they intend to use it.
Custom Landscapes by Design serves homeowners throughout Douglas County and surrounding Colorado communities, including Castle Rock, Castle Pines, Parker, Highlands Ranch, Sterling Ranch, Elizabeth, and southeast Aurora.
A custom landscape may combine structures, surfaces, water systems, living material, lighting, and boundaries. Planning those elements together helps each part connect visually and functionally while putting excavation, base work, underground systems, and finish work in the right order.
Projects can involve a complete yard or a focused improvement. In either case, the work should account for the surrounding landscape and the conditions that affect it.
How projects are approached
Access, grade, drainage, existing conditions, and how the space should work shape the plan before materials are selected.
Hardscape, walls, irrigation, planting, turf, lighting, and fencing are considered together so construction follows a practical order.
Structural work and living landscape decisions belong in the same conversation when they share elevations, edges, drainage, access, and finished use.
A completed project should be checked against the agreed scope and reviewed with the homeowner as a functioning outdoor space.
Verified industry recognition
The company’s Techo-Bloc certification is established in the project record and supports the hardscape design and installation work represented on this site.
