Experience The Enduring Vision Of Designs By Sundown 

In Colorado, where nature’s drama and design innovation intersect, landscape architecture becomes something more than a visual art—it’s a craft of connection. For Adam Hallauer, President of Designs By Sundown and a part of LUXE VISIONARIES, that idea has defined a 40-year legacy. “We didn’t start this company to build a business; we started with a passion for landscaping and a desire to create a place where like-minded folks could thrive,” Hallauer shares. Four decades later, the firm continues to lead with that same authenticity, cultivating landscapes that inspire, comfort and endure.

Rooted In Relationships
From its earliest projects to its most elaborate estates, Designs By Sundown has built not only outdoor environments but also long-standing partnerships. “People come first: clients, associates, the whole community around us,” Hallauer says. “That’s what makes us different.” Guided by the philosophy of always doing what’s right for the client, the firm has earned a reputation for honesty, artistry, and precision—a rare combination that turns outdoor spaces into enduring extensions of the home.

Shaping The Colorado Experience
For Hallauer, design is deeply personal. Having grown up building alongside his contractor father, he found his calling in landscape architecture’s perfect blend of creativity and craftsmanship. “What drew me in was the pace and scale of residential work,” he reflects. “You meet the client, design something meaningful and see it come to life within a season or two. It’s incredibly rewarding.” That same immediacy shapes Designs By Sundown’s ethos: to create environments that bring people together, whether through a quiet moment by a firepit or a lively gathering under the stars.

Innovation With Integrity
Innovation and sustainability have long guided the firm’s operations, from efficient scheduling and route density to technology-driven systems that reduce fuel use and waste. “We’ve always embraced innovation, not for the sake of being modern, but because it helps us do things better,” Hallauer says. “When you care about doing things the right way, sustainability follows naturally.”

Looking Ahead
As Designs By Sundown celebrates its 40th anniversary, Hallauer sees the milestone as both reflection and renewal. “Growth hasn’t been something we’ve chased. Rather, it’s something we’ve been pulled into by people who value what we bring,” he notes. “This chapter is about refining our craft and deepening our relationships. It’s about getting better, not just bigger.”
