You love your reptile and want the best life for him or her. As such, you may find yourself dreaming of the BEST habitat where your pet can crawl, slither, or climb to their heart’s delight.
Below are several DIY reptile enclosure plans to help inspire you to unleash your inner contractor and build your pet their dream home!
However, something that should be stressed is that when choosing an enclosure you will first need to determine exactly what your reptile’s needs are to keep him healthy and safe.
- How much space does he need?
- How much lighting and heat?
- Will he need to climb?
- Does he need more horizontal or more vertical room?
- Where in your house will you most appreciate your reptile?
- Is the cage going to be a focal point for visitors?
- Perhaps it will function as a showpiece in your room?
Once you have figured out spacing and location you’ll need to decide how you want to make the enclosure. Common options include repurposing old furniture or building from scratch. Naturally, this will depend on your time, skills, and budget.
Once you’ve determined these parameters, browse the enclosure ideas below to see what might suit your needs the best!
DIY Reptile Enclosure Plan #1: DIY Snake Cage (Recycled Cabinets)
This snake cage is made out of a repurposed cabinet. This idea is wonderful for those who do not have an advanced carpentry skillset or who like to reuse and repurpose things.
It’s especially fantastic for those who have an inclination to reduce their impact on the environment because it reuses something that would have otherwise been sent to the landfill.
Often old cabinets have a section that is open and allows for a piece of plexiglass to be installed, allowing for a simple viewing area with very little effort.
This cage is made from a cabinet that is wider than it is tall and has an open front, preferably with glass doors.
DIY Snake Cage Plan Pros
- Generally affordable
- Simple & straight forward build
- Aesthetically appealing
- Built-in storage and looking glass
DIY Snake Cage Plan Cons
- Can be hard to find
- Labor intensive
- Hard to transport (can be heavy)
- Limited options and flexibility with design
DIY Reptile Enclosure Plan #2: DIY Chameleon Cage (Refurbished Cabinet)
This is another great cage using a piece of cabinetry that had already served its original purpose. The cabinet is tall and narrow, making it ideal for a chameleon that wants to climb.
The original cabinet had glass doors that opened, making it easy access to clean, maintain, and visit the chameleon. However, instead of keeping the glass, which would have trapped in moisture and heat, the glass is removed and replaced with a screen.
This allows air to move through and makes it easier to regulate the temperature inside the cage with less risk of it becoming a hot box.
The seams were sealed with silicone and the rest of the wood was protected with a water-based wood sealant. A piece of glass was cut to fit the bottom of the cabinet, which allows plants and soil to grow inside the enclosure.
DIY Chameleon Cage Plan Pros
DIY Chameleon Cage Plan Cons
- Potentially hard to find
- Limited in design
- Wood may rot over time
DIY Reptile Enclosure Plan #3: DIY Iguana Cage
The green iguana is such a cute little guy when he comes home as a baby, but pretty soon he is going to need a LARGE enclosure. In fact, green iguanas landed the #5 spot among the largest pet lizards.
Generally, the iguana will need a cage that is at least 8-feet long, 8-feet high, and a minimum of 4-feet wide. This gives him room to grow and move freely without feeling cramped.
It’s almost impossible to find a sufficient iguana cage ready-made so you will have to make your own enclosure.
This plan gives you a basic idea of how to get started, the basic measurements, and the best materials that are sturdy, yet affordable.
DIY Iguana Cage Plan Pros
- Highly customizable
- Can be on wheels (easy to move)
DIY Iguana Cage Plan Cons
- Labor intensive
DIY Reptile Enclosure Plan #4: DIY Enclosure for Brazilian Rainbow Boa (Old windows)
This plan is made from old, glass windows. As such, it is excellent for repurposing!
However, it should be noted that every project will be completely unique because everyone’s supply of old windows will be different. Under the right circumstances, this plan makes an excellent snake enclosure!
The plan design uses a glass cutter to score the glass and then breaks it along the score lines. This must be done with safety gear and a cutting oil (like mineral) to make a nicer cut and preserve your tools.
Additionally, the newly cut edges need to be sanded so they aren’t so sharp. The glass edges are then framed with wood and sealed with silicone and the result was essentially a DIY terrarium.
However, the cost is minimal, particularly if you already have the tools and just need to gather supplies.
It’s hard to maintain the temperature and humidity in a structure like this, but it is customizable so you can work around your parameters until you have a system that works for you.
🤓Expert Tip: Once you’ve selected the appropriate DIY reptile enclosure plan and finished building it, you’ll naturally want to furnish your pet’s new home with plenty of pretty foliage! Just be sure to use only non-toxic and reptile safe plants that won’t prove hazardous to your scaly friend.
DIY Brazilian Rainbow Boa Plan Pros
- Almost free
- Similar to store bought aquarium
DIY Brazilian Rainbow Boa Plan Cons
- Requires glass cutting
- Hard to maintain temperatures
DIY Reptile Enclosure Plan #5: DIY Aussie Python & Snake Enclosure
The instructions for this habitat are geared toward people who have pythons or similar snakes. It’s completely customizable and uses melamine (or pine wood) and glass for the main structure.
You will need basic tools including:
However, the plan developer notes that you can save yourself time (and possibly money) by buying your material at a store that will pre-cut the pieces for you.
These structures allow you to customize where you will put your heating and lighting sources and can be stackable if you have multiple snakes.
DIY Aussie Python & Snake Enclosure Plan Pros
- Easy to clean
DIY Aussie Python & Snake Enclosure Plan Cons
- Carpentry skills required
- Labor intensive
- Poor tools needed
DIY Reptile Enclosure Plan #6: Indoor Tegu Enclosure
The design builder for these instructions also prefers white, double-sided melamine boards that can be cut to your preferred size.
However, unlike a generic lizard enclosure, these instructions are specific to the tegu, which allows them to give specific measurements.
This means that if you follow the instructions exactly, you’ll wind up with an enclosure that is PERFECT for your Tegu!
In addition to basic power tools you will also need to be able to set tracks (this design has sliding doors) and countersink screws.
The design is attractive and tidy when done and is an excellent size (8 ft long) for Tegu’s.
DIY Indoor Tegu Enclosure Plan Pros
- Easy to clean
DIY Indoor Tegu Enclosure Plan Cons
- Carpentry skills needed
- Multiple Pieces
- Time consuming
DIY Reptile Enclosure Plan #7: Basic Reptile Enclosure
This basic reptile enclosure is a wooden box that can be customized exactly how YOU want!
The plans include designs for both a horizontal and a vertical cage. Both are made using plywood and either glass or plexiglass installed on tracks.
The images are clear for all designs and measurements are given in each example.
The horizontal gives the measurements for a corn snake or ball python with a cage that measures 3-feet by 1.5-feet by 1.5-feet.
The vertical measurements are for a structure that would house a crested gecko. This example measures 1.5-feet by 3-feet by 1.5-feet.
A bonus enclosure plan is for a multiple reptile unit with three cages inside the unit. It is a vertical structure made in the same style as the previous examples. The entire unit is 6-feet by 3-feet by 2-feet, which means each reptile cage would be 2-feet by 3-feet by 2-feet.
The best part of these basic designs is that if you get the wood pre-cut, you’ll have very little work left to do and will not need much more than a drill in way of tools.
DIY Basic Reptile Enclosure Plan Pros
- Quick build
DIY Basic Reptile Enclosure Plan Cons
- Limited design flexibility
- Expensive (compared to others)
- Not necessarily attractive
- Measurements are variable
DIY Reptile Enclosure Plan #8: Purchased Plans (eBay – multiple sizes)
These plans are for sale and are prepared for you. As such, they are ideal for both people who don’t excel at making customizable cuts and those who want to be told EXACTLY what to do.
The purchase includes 10 plans for six different types of styles.
These plans can be used to build:
- Snake enclosure
- Lizard enclosure
- Chameleon enclosure
- Gecko enclosure
- Iguana enclosure
The designs are wood framed with either all screen siding or plywood sides. They can be adapted to use plexiglass. However, this is ultimately where the modifications end as they can NOT be adapted to allow heating or lighting to be on the inside of the habitat.
This is because they are designed for lighting to sit on the outside, which is typical of most enclosures.
DIY Purchased Reptile Enclosure Plan Pros
- Comes with CD
- Multiple sizes
- Reptile specific
DIY Purchased Reptile Enclosure Plan Cons
- Costs $10 for plan
- Can’t see quality prior to build
- Rigid sizing
- Doesn’t include costs for materials
Wrapping Up DIY Reptile Enclosure Plans
There are almost a limitless number of plans out there when it comes to making DIY reptile structures. People can build habitats from a variety of scavenged or repurposed materials or by simply starting a new build with fresh wood or melamine.
Builds can be as simple as removing glass from a cabinet and replacing it with screen and then sealing the structure, or as complex as making a custom piece that beautifully fits into a particular part of the house.
The reality of reptile husbandry is that many reptiles will outgrow cages that are commercially made so planning ahead and knowing exactly what you want will save you some trouble in the long run.
