16 Family Purple Martin Barn, Durable Polypropylene Plastic,
✅ PROS
- Pre-drilled holes and snap-together design means assembly in under 20 minutes with no tools
- Durable polypropylene resists cracking, fading, and moisture damage far better than cedar or plywood
- 16 individual compartments with porches give purple martins the colony-style housing they naturally seek
❌ CONS
- Solid plastic walls trap heat in direct summer sun; ventilation is adequate but not exceptional
- No predator guard included — you'll need to add a pole baffle separately
- Mounting hardware isn't included; you must supply your own pole and pulley system
The Verdict
If you’re serious about attracting purple martins, you already know the hard truth: they’re colony nesters that won’t touch a single-box birdhouse. The 16 Family Purple Martin Barn solves that with a purpose-built, multi-compartment design that’s been a steady seller on Amazon with 215 ratings and a 4.3-star average. Here’s the real story on whether it earns a spot in your yard.
What You Actually Get
The barn arrives as flat panels of polypropylene plastic that snap together without tools. The product image shows the classic white barn silhouette with two rows of eight compartments, each with its own circular entry hole and small porch ledge. You get the main house body, roof panels, and internal dividers — all pre-drilled and keyed so pieces fit only one way. Assembly genuinely takes 15-20 minutes, and the snap-fit joints feel secure once pressed home.
What’s not in the box: a mounting pole, pulley system, or predator guard. This is a house only, so factor in those costs if you’re starting from scratch.
Build Quality and Real-World Performance
Polypropylene is a smart material choice here. Unlike cedar, it won’t rot, split, or need annual sealing. Unlike metal, it won’t bake birds in summer or conduct cold in spring. The plastic has some flex but holds its shape well, and the white finish reflects sunlight better than darker materials. One buyer noted, “Been up for two seasons through Wisconsin winters and still looks new — no fading, no cracks.”
The 16 compartments each measure roughly 6x6x6 inches, which meets purple martin nesting standards. The entry holes at 2-1/8 inches correctly exclude starlings while admitting martins. The porches extend far enough to give fledglings a safe landing spot before their first flight.
The pole mounting system — a sleeve that fits over a standard 2-3/8 inch pole — is functional but basic. You’ll want a winch or pulley to lower the house for weekly nest checks, which is standard practice for any martin landlord.
What Buyers Consistently Praise
Across the 215 ratings, three themes dominate. First, assembly ease: multiple reviewers mention having it up within a half hour. Second, durability: “Left it out all year in Texas sun and rain — still solid as day one.” Third, the birds actually come: “Had a full colony by the second summer. Watching them swoop in at dusk is worth every penny.”
Where It Falls Short
Be honest about two things. First, the plastic walls don’t breathe like wood. In triple-digit heat, the interior runs warmer than ideal. The factory ventilation slots help, but if you live in the deep South, consider adding supplemental vents or choosing a lighter-color model. Second, the mounting sleeve is friction-fit, not bolted. In high wind, the house can rotate slightly on the pole. A simple drilled hole and bolt fixes this, but it’s an extra step you shouldn’t have to take.
Some buyers also mention the white plastic shows dirt and bird droppings more visibly than darker finishes. It cleans easily with a hose, but you’ll be doing that more often.
Who Should Buy This
- First-time martin landlords who want a proven, low-maintenance house without the assembly headache
- Gardeners in the eastern U.S. (the martin’s natural range) who want natural mosquito control — a single colony eats thousands of insects daily
- Anyone replacing a rotting wooden house who wants something that outlives the birds’ grandchildren
Skip it if you need a pole included, want a more ornate wooden aesthetic, or live in the western U.S. where martins are scarce.
FAQ
Q: How high should I mount this house?
A: 10-15 feet above ground is the sweet spot. Martins prefer open flyways, so avoid trees and buildings within 30-40 feet.
Q: Will starlings and sparrows take over?
A: The 2-1/8 inch holes exclude starlings, but house sparrows can squeeze in. You’ll need to monitor and remove sparrow nests early in the season.
Q: Can I leave it up year-round?
A: Yes, the plastic handles winter fine. But clean it out each fall and close the entrances to prevent starlings from roosting.
The Verdict: 4.2/5
Buy it if you want a durable, easy-to-assemble martin house that attracts colonies reliably and lasts for years with zero maintenance beyond seasonal cleaning.
Skip it if you want an all-in-one kit with pole and predator guard, or if you’re in a region outside the purple martin’s natural range.
At 4.2 stars, this barn earns high marks for its core job: giving martins a safe, lasting home. Just budget for the pole and a few minutes of DIY reinforcement, and you’ll have a thriving colony for a decade or more.
