A burning desire to produce a superior product/service because we see it as a reflection of ourselves.

Landscape Design.

Listen to your first outdoor party

At no charge, we will meet with you on-site for a fact-finding consultation to assess existing site conditions, your home’s architectural style, and your outdoor lifestyle. We will explain our design process and our service levels, which range from simple hand-sketches to fully realized computer-generated 3D renderings.

The key to any successful landscape is a successful design. Once you’ve decided on a design service level, we will perform a site survey to review the area, assess micro-climate conditions, take photos, and look for potential challenges and opportunities. You will be matched up with a dedicated designer who will lead your project from start to finish, but you’ll also receive the benefits of working with our entire team, who will use their collective experience to come up with solutions and ideas specific to your project. Based on all of this, your designer will create a design just for you.

Your designer will present a customized landscape design, complete with material choices and budget information. With your input, we will make modifications until we have a final design that meets your approval. Our thoughtful approach to design and our clear documentation of every step ensures that everyone understands and agrees on the desired result. At this point, your project is ready for construction.

With new technology you are able to add trendy lighting to every outdoor space, from woven chandeliers to LED lanterns, we are seeing a ton of variety that can make your patio, porch, sun-room outdoor deck a true extension of your home.

Mixed Materials & Textures

A seamless transition between indoor and outdoor space begins with the right furniture. Indoor-outdoor furniture should reflect your interior style, whether it’s traditional, transitional, contemporary or modern. Ditch matching outdoor sets! 2021 calls for mix-and-match materials which create a personalized space.

Water Management.

Listen to your first outdoor party

Design & Installation

Smart resource management of our water starts with the design. At Designs By Sundown, our team of water specialists and designers utilize the newest, proven technology in carefully planned irrigation designs that take into account site conditions through proper hydro zoning. Whether it is a new project or an existing landscape, our design adapts to your specific needs.

Systems Inspections & Maintenance

From sprinkler turn ons, to blow outs, or any needed repair in between, Designs by Sundown’s trained and certified irrigation technicians troubleshoot and inspect your system each step of the way. Proper preventative maintenance will extend the lifespan of your sprinkler system while accounting for the evolving needs of your custom landscape. 

Water Conservation

Water is our most precious resource. As much as 50% of water used outdoors is lost to wind, evaporation, over-watering, and run off caused by an inefficient irrigation system. As Denver’s premier landscape firm, our industry leading technicians provide proper programming and adjustments that can reduce costs by up to 20%, with the average home saving over 5,000 gallons annually by reducing water waste.

Rebate Sharing & Assistance

We make the savings easy for you with dozens of water rebates available throughout Denver and the Denver metro area. Our service professionals help provide the guidance to make the savings simple. 

Smart Irrigation

At Designs by Sundown, we strive to balance the water requirements of your landscape with aesthetic elegance. Our comprehensive approach considers all aspects of soil, plant species, weather patterns, and climates.

Integrative Pest Management (IPM)

IPM is a long-term approach Designs by Sundown uses to prevent pests and pathogens. Through biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties we are able to prevent and manage threats to a landscape. This translates into building healthy soils, effectively conserving water, selecting organic fertilizers, and fending off damaging diseases, weeds, or insects with carefully selected sprays and injections.

Environmental Stewardship

We understand that stewardship means creating a safe space for family, pets, and nature now, and for future generations. Designs By Sundown exercises a holistic approach when selecting what type of control measures to apply. The careful approach considers the health of pollinators, pets, children, natural waterways and wildlife.

Nutrient Management

Promoting healthy plant growth and vigor helps your landscape outcompete and resist weeds and pests. This can help reduce the need for control applications. Designs by Sundown offers organic fertilizer options and customized nutrient management plans that will best fit the needs of your lawn, trees, and shrubs.

Inspect & Treat

One size does not fit all. Through carefully inspecting plant material and site conditions, our certified technicians only perform applications when pest thresholds exceed healthy tolerance levels. This precise approach reduces environmental impact and client costs.

Usability

Outdoor living and entertainment should not stop at dusk. At Designs by Sundown, we believe some of the best memories are made hosting friends and family outdoors in the cool evening hours. Obviously, we do not sit in our homes in the dark with the lights turned off. Your outdoor living space should not be any different. Our team of lighting specialists bring your home exteriors to life by utilizing the newest trends and technology for a stunning and alluring experience. 

Design, Installation & Maintenance

Through carefully planned designs that bring landscapes to life, our trained and certified installers and technicians work together to achieve the highest energy efficiency guidelines and standards. From initial install to system upkeep and any troubleshooting along the way, the Designs by Sundown service team is trained to address any possible lighting need. 

Aesthetics

A lighting system adds a fresh dimension to your landscape by bringing it alive through zoning, dimming, and color adjustments. Nighttime is the perfect time to highlight the depth, cohesion, and focal points of a beautiful landscape. From patios and outdoor kitchens, to architectural elements and planting specimens, your home should stand out. 

Safety & Security

Help make your home safer by illuminating transition points at walkways and steps. A well-lit exterior also serves as a deterrent to intruders while increasing curb appeal. Illuminated address columns or signage provide some of the initially welcoming touches and assistance to arriving guests or service providers. Remember, landscape lighting is an art and requires certified and trained professionals to follow manufacturer and industry standards to prevent fire hazards from excessive heat or improper connections.

Pool, Spa & Water Features.

Listen to your first outdoor party

Design & Installation

Every space is unique. Our design team creates the pools, spas, fountains, or cascading ponds for the distinctive focal or accent point that perfectly nests into your outdoor living space. With an eye for detail, our construction team can make your imagination become reality! Through strict adherence to permitting and careful engineering, we build pools and water features to account for soils, safety, and long-term durability.

Aesthetics & Acoustics

Whether it is an intimate, gentle white noise or a bold backdrop, the acoustics of flowing water immediately elevate the impression of an outdoor entertainment space. At Designs by Sundown, we can create the perfect unique water feature to compliment any landscape.

Pools, spas, and ponds can be designed in any shape or size and offer vanishing or infinity edges combined with fire or lighting elements for a stunning display.

Maintenance & Service

All bodies of water require diligent care and upkeep to maintain. Designs by Sundown’s team of certified and trained technicians provide all necessary maintenance and repair services for pools, spas, ponds, and fountains. Our service technicians provide cleaning, pH balancing and algae management through custom tailored products and agents that fit your needs.

Recreation

From family fun to dinner parties, pools and spas provide a perfect venue for gatherings. Whether it’s the intense heat of a Colorado summer day, or the chilly Colorado winter night, a pool or spa can provide the perfect quiet escape for relaxation in any backyard.

Aquatic Life

We are not the only ones enjoying the water. Designs by Sundown’s certified water feature technicians understand the delicate balance and care required for healthy fish and ornamental aquatic plants.
