What Designs By Sundown does
Designs By Sundown is a full-service luxury residential landscape firm headquartered in Littleton, Colorado, serving the Denver metropolitan area (including Denver, Boulder, Evergreen, Castle Rock/Castle Pines, and Parker). Founded in 1985 by Michael Hommel from a garage with a few trucks, the company has grown to 300+ professionals delivering end-to-end landscape services — conceptual design, 2D and 3D renderings, immersive 3D walkthroughs, hardscape and softscape construction, pools and spas, outdoor features, outdoor furniture curation, and year-round property care. The company's primary customer segment is high-net-worth residential property owners in the Denver metro seeking a single, white-glove vendor to design, build, and maintain estate-scale outdoor environments. Select institutional work (Cheyenne Mountain Zoo, Denver Botanic Gardens, a National Register historic mansion) demonstrates capability beyond residential, though residential remains the dominant revenue base.
The company operates a hybrid revenue model combining one-time project fees for design-build construction with recurring subscription contracts for property maintenance, supplemented by specialty service revenue across pool maintenance, irrigation, landscape lighting, and seasonal services. Go-to-market is direct-to-consumer enterprise field sales: consultation booking via website and phone, in-person property assessments, customized design proposals, and dedicated client managers providing bi-weekly updates. The company is privately held and consolidated under Mariani Enterprises, LLC (Mariani Premier Group), with Adam Hallauer serving as President & CEO after 23 years with the firm. Pricing on recurring services is transparent (e.g., weekly pool maintenance from $85/visit, lighting system tune-ups from $140), while construction projects are quote-based and vary by scope. Competitive positioning is anchored by 100+ industry awards, BBB A+ rating sustained over 20 years, HGTV Landscapers' Challenge championship, and multiple professional certifications (NALP, ALCC, ASLA, QWEL, ISA, CPO, Select Certified Irrigation).
