The 'Grand Haven' Purple Martin House | S&K Heavenly Haven 10-Room Starling-Resistant Pole-Mount Habitat

The Experience

Ten rooms. Two floors. An attic tier. And a design philosophy centered on giving Purple Martins exactly what they need — generous compartment dimensions, passive starling exclusion, and the raise-and-lower pole compatibility that separates a managed colony from a gamble. The Grand Haven is the Purple Martin landlord's answer to quality over quantity — fewer rooms than the flagship models, but each one sized with the kind of intentionality that serious colony stewardship demands. Built from UV-stabilized copolymer plastic in the USA by Scenic Rivers Industries, fully compatible with The Elevator pulley system pole, and uniquely field-customizable with a paintable exterior that lets the landlord integrate this house into any landscape aesthetic they've built. This is a purple martin nesting box that arrives ready to perform — and ready to become exactly what you need it to be.

Scientific Engineering

• Starling-Resistant Crescent Entrance Holes (SREH): Each compartment features a precision crescent-shaped opening measuring 3"W x 1.125"H — dimensioned to admit Purple Martins comfortably while physically preventing the larger body profile of European Starlings from gaining entry. Passive exclusion, active every hour of every day.
• Dual-Tier Room Architecture: Eight generously proportioned main floor apartments measure 8.25"L x 8.5"W x 6"H — significantly larger than the industry-standard 6"x6" compartment — supporting larger clutches and healthier nestling development. Two dedicated attic compartments measuring 8.5"L x 4"W x 6"H extend colony capacity with a distinct spatial configuration suited to birds that prefer a lower-profile nesting environment.
• Integrated Nest Bowls & Textured Floors: Molded nest bowls on each compartment floor help martins position and secure eggs during incubation, while textured black plastic floor surfaces provide nestlings with superior grip during the critical pre-fledge period.
• Upward-Swinging Access Panels: Each compartment door swings upward for direct nest monitoring, parasite management, and end-of-season cleanout — fast, tool-free access that makes the three-to-five day nest check schedule manageable rather than burdensome.
• Center Pole Pass-Through Design: Engineered for a 2" outer diameter pole through the center of the structure — fully compatible with The Elevator pulley system pole — enabling complete raise-and-lower colony management without a ladder.
• Pitched Roof with Weather Protection: White pitched roof provides cooling shade and deflects precipitation away from the colony, maintaining interior comfort during both peak summer heat and active storm events.
• Paintable Exterior: The all-white copolymer exterior accepts paint, allowing landlords to customize the house's appearance to complement any landscape or colony site aesthetic — a feature found on few production martin houses at any price point.
• UV-Stabilized Copolymer Plastic: Weather-resistant construction resists fading, cracking, and structural degradation across decades of outdoor exposure regardless of climate or seasonal conditions.

Boutique & Conservation Values

• Raise-and-Lower Compatible: Full compatibility with The Elevator pulley system pole puts nest checks, competitor eviction, and seasonal management within reach without a ladder — the management standard for any serious colony program.
• Customizable Colony Aesthetics: The paintable exterior gives the Grand Haven a flexibility rare in production martin housing — adapt the visual profile of your colony site to the landscape you've built, rather than the other way around.
• Scenic Rivers Industries: Your purchase directly supports a workshop providing dignified, meaningful employment for people with disabilities — making the Grand Haven one of the few purple martin nesting boxes that contributes to both wildlife conservation and human community in a single transaction.
• Heritage Manufacturing: Proudly Made in the USA.
