Would you invest in a large-scale renovation to bring a vacation-style experience into your own backyard?

An Olathe couple has transformed a portion of their land into a 100,000-gallon swimming lagoon inspired by Tahiti. The two-acre feature serves as a private tropical-style retreat designed to withstand local climate cycles.

Why it matters

The project represents a shift in residential landscaping where homeowners prioritize creating immersive, resort-style environments on their own land. By utilizing durable filtration and materials, the couple created a permanent getaway while maintaining proximity to their family.

The lagoon measures 100 feet long and 50 feet wide, featuring a 23,000-pound granite boulder and six cascading waterfalls. Shorelines are finished in tumbled white marble with water depths ranging from five to six and a half feet.

The players

Good Earth Water Gardens

This landscaping company served as the primary contractor for the construction of the lagoon and its stone barriers.

The details

Constructed by Good Earth Water Gardens, the lagoon features a specialized filtration system and artificial palm trees built with real husks. Granite boulders used in the design were sourced from 14,000-foot elevations in Colorado to enhance the tropical look.

The couple spent nearly a year building the lagoon between 2025 and 2026.

Culture Shift

This project exemplifies the broader trend of staycation architecture, where homeowners replace traditional pools with immersive environments. This move reflects a societal shift toward prioritizing domestic space for leisure over conventional outdoor design.

Residents looking to mirror this tropical aesthetic should note that high-end landscaping projects require significant space and professional water filtration expertise. The property's unique design has already drawn interest from local photographers for private sessions.

The takeaway

Large-scale water features require careful planning to ensure they can withstand local climate fluctuations like freezing winters. Homeowners should focus on durable materials and professional filtration systems to ensure long-term functionality.
