Best Birdhouses for Chimney Swifts: Pre-Built Towers vs DIY
Contents
You’ve spotted them every summer evening—those small, dark birds with crescent wings wheeling above your neighborhood before funneling into someone’s chimney. Then one year, they don’t come back. Your local chimney got capped, or the old brick stack on the abandoned garage came down. Chimney swifts lost their natural nesting sites centuries ago when we cleared the big hollow trees, and now they depend on our chimneys. When those disappear, they have nowhere to go.
Putting up a proper swift tower is one of the most direct conservation acts a homeowner can do. But here’s the catch: a regular birdhouse won’t work. Swifts need a tall, narrow, rough-walled shaft that mimics a chimney flue. They can’t perch; they cling to vertical surfaces. So the search for the right product quickly turns confusing. You’ll find decorative boxes, gourd houses, and all manner of cute cottages that a swift would never use. Sorting through the noise takes time.
This guide cuts through that confusion. I’ve dug through the options, weighed the DIY route against pre-built towers, and considered the real-world installation challenges. Below you’ll find two solid picks that serve very different needs, plus a deep dive into design specs, placement, predator control, and the ethical questions around monitoring. Whether you’re a woodworker wanting a weekend project or someone who wants a ready-to-mount tower, there’s a path here for you.
Here’s how the two main approaches stack up at a glance:
| Features | DIY Build Book | Decorative Craft Houses |
|---|---|---|
| Primary Purpose | Educational, construction guide | Craft project, decor |
| Material | Paper instructions | Plywood and cotton |
| Quantity | One book, many plans | 8-piece set |
| Dimensions | Varies by plan | 6.38 x 5.1 x 9 inches each |
| Best Use Case | Learning to build | DIY painting, indoor display |
Birdhouses You Can Build…
This isn’t a birdhouse at all—it’s the manual that gets you there. Birdhouses You Can Build in a Day from Penguin is a project book packed with straightforward plans. For chimney swifts, you won’t use the standard box designs inside. Instead, you’ll adapt the woodworking techniques and construction basics to build a taller tower. Think of it as a starting point for understanding joinery, wood thickness, and weatherproofing.
Who is this for? The hands-on person who owns a circular saw and wants control over the final product. Pre-fabricated swift towers are rare and often pricey. Building your own from scratch costs less in materials, but you need reliable guidance. This book provides clear, approachable projects that build your confidence before you tackle a larger tower. It sits on your workbench as a reference while you figure out the internal dimensions that swifts actually need.
You’ll need to look elsewhere for specific swift tower measurements. The book covers general birdhouse construction, not species-specific requirements. That means you’ll need to do a bit of research on proper interior dimensions, ventilation, and the rough interior surface that swifts require. Also, the ‘in a day’ promise applies to the simpler projects in the book, not necessarily a full chimney swift tower, which takes more time and material.
- Contains multiple woodworking plans for various birdhouse styles
- Focuses on quick, achievable builds for beginners
- Teaches practical skills like measuring, cutting, and assembling
- Requires you to source your own lumber and fasteners
- Best used as a foundation for adapting a custom swift tower design
Best for: The DIY enthusiast who wants to learn construction basics and adapt them into a custom-built chimney swift tower without paying premium prices for a pre-made unit.
Make Market 2-Story Wood…
2nd Pick
Make Market
Make Market 2-Story Wood Birdhouse – Unfinished Hanging Birdhouse with Porch & Chimney for DIY Crafts & Indoor Decor, 9" Tall, 8 Pack
- Unfinished
- 6.38" x 5.1" x 9" (16.2cm x 12.95cm x 22.86cm) birdhouse size
- 8 birdhouses
Here’s the honest truth: this 8-pack of unfinished, two-story hanging houses is not a functional chimney swift tower. Swifts need an open shaft, not a porch with a perch. But this set solves a different problem entirely—it’s an excellent base for a craft project that raises awareness. You can paint these with kids, use them as decorative pieces, or repurpose them for smaller cavity-nesting birds like chickadees or wrens.
Each piece measures 6.38 x 5.1 x 9 inches, making them a manageable size for tabletop crafting. The unfinished plywood surface takes paint and sealant well. The attached cotton cord means they’re ready to hang on a shepherd’s hook or tree branch. For a classroom activity about native birds, or a weekend project to teach kids about wildlife conservation, this set works well.
But don’t mistake these for serious wildlife housing. The wood is thin, the interior is smooth, and the dimensions are far too small for swifts. If you hang them outdoors for other birds, you’ll want to add a predator guard and apply an exterior-grade sealant. The cotton cord will degrade in the weather, so replace it with wire or durable twine if they’ll be outside long-term. These are craft supplies, not habitat.
- Bundle of 8 identical unfinished houses for group projects
- Compact size suitable for indoor display or small garden accents
- Simple two-story design with a decorative chimney piece
- Pre-drilled with cotton cord for immediate hanging
- Ideal for painting, staining, or decoupage customization
Best for: Crafters and educators who want an inexpensive, paintable surface for decorative projects or awareness-building activities about bird conservation, not for actual swift habitation.
How We Chose These Products
The selection process started with a hard question: what actually works for chimney swifts? Most products on the market fail the basic test. They’re too small, too smooth, or shaped like a typical songbird box. Swifts require a very specific setup, and few retail options meet that bar. So the focus shifted. I looked for products that genuinely help someone create suitable habitat, either through education and DIY construction or through adaptable craft materials that serve a secondary purpose.
Each pick was evaluated on practicality, real-world usability, and the gap it fills. The book earns its place by empowering a builder to create a proper tower at a fraction of the cost of a pre-fabricated one. The craft set earns its place by serving a different audience—those who want to engage with bird conservation through a hands-on, visual project. Neither is a perfect, ready-to-use swift tower, and this review is transparent about that limitation. The goal is to give you a starting point, not a false promise.
Buying Guide: What Really Matters
Before you buy anything, understand the non-negotiable design specs for a chimney swift tower. The interior must be rough. Swifts cling to vertical surfaces with sharp claws; smooth wood or metal gives them nothing to grip. The internal dimensions should be roughly 12 by 12 inches, with a height of at least 3 feet for a nesting tower, and much taller for a roosting tower. Ventilation is critical to prevent overheating, and a predator guard is essential.
Placement determines success. Mount the tower on a pole in an open area, at least 10 to 12 feet high. Swifts need a clear flight path to swoop in from below. Keep it away from trees and buildings where predators can jump onto it. A metal pole with a baffle is your best defense against raccoons and snakes. Also, think about the sun. A tower that faces south or west gets hot; some shade during the day helps regulate temperature inside.
Consider the cost breakdown honestly. A pre-built tower can run several hundred dollars, plus shipping. A DIY kit or plan is cheaper, but you’ll need tools like a saw, drill, and sander. If you don’t own those, factor in the cost or find a local maker space. The book reviewed here is a low-cost entry point, but you’ll need to buy lumber, screws, and a mounting pole. Weigh your budget and skill level before committing to a path.
Our Top Recommendation
For most people, the best route is the DIY approach using Birdhouses You Can Build in a Day as a starting guide. Pre-built swift towers are scarce, and the ones you find online often come with hefty shipping costs and long lead times. Building your own gives you control over materials, dimensions, and placement. You can use exterior-grade plywood or cedar, add a textured interior surface, and customize the height for your specific yard. It’s more work, but the conservation payoff is worth it.
The Make Market craft set serves a different purpose. If your goal is purely decorative, or you’re looking for an engaging project to teach kids about birds, it’s a fine choice. Just don’t expect it to attract swifts. Use it as a conversation starter, then build or buy a proper tower to back up the message. For those who want a simpler, no-tools option, keep an eye out for specialized swift towers from conservation groups, but be prepared for the higher cost.
Frequently Asked Questions
How do I handle HOA restrictions or landlord permissions for a tower?
Check your HOA covenants or lease agreement first. Many have rules about freestanding structures over a certain height. Frame it as a conservation feature, not a backyard shed. Offer to place it in a less visible spot or use a pole that can be removed easily. If you rent, written permission from the landlord is a must. Show them the tower is low-maintenance and doesn’t damage the property.
What’s the real cost difference between a pre-built tower and a DIY build?
A pre-fabricated swift tower typically costs between $200 and $500, plus shipping. DIY costs break down to about $50 to $100 for lumber, $20 for screws and hardware, and a few hours of labor. If you lack tools, add $100 or more for a basic saw and drill. The book reviewed here is around $15, making it the cheapest starting point by far.
When is the best time to install a tower, and what if swifts arrive late?
Put the tower up in late winter or early spring, before swifts return from South America in April or May. If they don’t show up the first year, don’t panic. Swifts are colonial and often follow social attraction calls. Playing recorded swift calls near the tower during migration season can help. Patience is key; some towers sit empty for a season before discovery.
How can I monitor nesting success without disturbing the birds?
Skip opening the tower for inspections. Instead, set up a small camera on a pole nearby, angled at the entrance. Many trail cameras have motion sensors and night vision. You’ll see activity without causing stress. Observe from a distance and avoid approaching the tower during the first few weeks after the birds arrive. For more ideas, check out guides on small cavity nesters for comparison.
What specific predator deterrence strategies work beyond standard guards?
Raccoons are clever. A cone-shaped baffle below the tower works, but make sure it’s wide enough—at least 18 inches in diameter. For snakes, grease the pole with a petroleum jelly that you reapply monthly. Trim any overhanging branches within 10 feet of the tower. Consider a metal pole instead of wood, as snakes grip wood easier. For a deeper look at structural choices, see this chimney swift building guide.
Can I use a decorative house like the Make Market set for swifts?
No. The interior is too small and smooth. Swifts need a rough interior surface to cling to, and the entrance hole on a standard house is wrong. These are decorative pieces. If you want to attract swifts, you need a tower that mimics a chimney flue. For other species that might use such a box, compare options for bluebird houses instead.
