The Complete Guide to Dog Kennel Under Stairs Ideas — DIY to Luxury

That awkward triangular space under your staircase? Most homeowners use it to store boxes, old shoes, or nothing at all. But if you have a dog, that dead space is actually a golden opportunity.

A dog kennel under stairs gives your pup a cozy, den-like retreat right inside your home. It keeps them close to the family, off the furniture, and out of the way — all without taking up any extra floor space.

The best part? There are dog kennel under stairs ideas for every budget, every home style, and every skill level. Whether you want a quick DIY weekend project or a fully custom luxury build, this guide covers it all.

Let’s dig in.

1. Why the Space Under Your Stairs Is Perfect for a Dog Kennel

Dogs are den animals by nature. In the wild, their ancestors rested in small, enclosed spaces that felt safe and protected. That instinct doesn’t go away in a domestic dog.

The space under your stairs naturally mimics that feeling. It’s tucked away, slightly enclosed, and just the right size for a dog to feel secure without feeling trapped.

On top of that, it’s space your home already has. You’re not building an extension or sacrificing a room. You’re just putting a forgotten corner to work.

It works whether your stairs are open or closed, small or large, carpeted or wooden. And with the right design, it can look like it was always meant to be there.

2. Things to Plan Before You Build

Before you pick up a hammer or call a carpenter, a little planning goes a long way.

Measure Your Space First

Grab a tape measure and note the height, width, and depth of the area under your stairs. Then measure your dog — specifically their height when standing and their length from nose to tail.

Your dog should be able to stand up, turn around, and lie down comfortably inside the kennel. As a rough guide:

• Small dogs (under 25 lbs): around 24″ wide x 18″ tall
• Medium dogs (25–60 lbs): around 36″ wide x 24″ tall
• Large dogs (60+ lbs): 48″ wide x 30″ tall or more

Know Your Stair Type

Closed-riser stairs (solid steps with no gaps) are the easiest to work with. You simply frame out the existing space and add a door.

Open-riser stairs (steps with gaps between them) are trickier. You’ll need to add a back wall, side panels, and a floor before you can enclose the space properly.

DIY or Hire a Carpenter?

A basic DIY build using plywood and a gate door can cost as little as $100–$300 if you already have some tools.

A mid-range built-in with cabinet doors and storage will typically run $500–$1,500 if you hire a handyman.

A fully custom or luxury kennel with designer finishes can go $2,000 and above depending on materials and features.

3. 14 Dog Kennel Under Stairs Ideas

1 — Classic Built-In Dog Kennel Under Stairs

A built-in dog kennel under stairs is the gold standard. It looks like it was designed with the house, not added as an afterthought.

The idea is simple: frame out the space, line the walls, add a door, and finish everything to match your existing trim and paintwork. When done well, it blends seamlessly into your hallway or living room.

Use MDF or plywood for the walls, and finish with the same paint colour as your skirting boards. Add a small name sign above the opening for a personal touch.

Best for: Homeowners who want a permanent, polished look that adds real value to the home. Materials to use: Plywood or MDF, pet-safe paint, wood trim, hinged or sliding door.

2 — DIY Under Stairs Dog Kennel with a Gate Door

If you want to save money and enjoy a weekend project, a DIY under stairs dog kennel with a simple gate door is a great starting point.

You don’t need to be a skilled carpenter. A basic frame built from 2×4 timber, lined with plywood panels, and finished with a hinged gate gives you a functional kennel in a weekend.

The gate door is key here. It lets air and light flow through while still giving your dog a defined boundary. It also lets them see the room, which reduces anxiety compared to a fully closed box.

Tips for your DIY build:

• Use screws, not nails, for a stronger frame
• Sand all edges smooth before your dog uses the space
• Line the floor with a rubber mat or vinyl tile for easy cleaning
• Use pet-safe, water-based paint on all interior surfaces

Best for: Renters with permission to build, or homeowners on a tighter budget.

3 — Under Stairs Dog Kennel with Storage

Why settle for just a dog space when you can have a dog space and extra storage?

An under stairs dog kennel with storage divides the area cleverly — your dog gets a cozy nook on one side, and you get shelves, drawers, or cubbies on the other.

Use the storage side for dog essentials like leashes, harnesses, treats, grooming brushes, and poop bags. Everything in one place, right by the door.

You can also add hooks on the outer panel for leashes and a small basket at the bottom for muddy paws supplies. For more inspiration on organising your dog’s essentials, check out these dog leash station ideas.

Best for: Busy households that need organisation alongside a dog-friendly space. Materials to use: Plywood carcasses, drawer runners, cabinet hinges, and easy-clean shelf liner.

4 — Dog Kennel Under Open Stairs

A dog kennel under open stairs is one of the more challenging builds — but also one of the most striking results.

Because open risers have gaps between each step, you can’t simply frame out the existing walls like you would with closed stairs. You need to create the enclosure yourself.

Start by building a simple back wall and two side panels. Then lay a smooth floor across the ground beneath the steps. Once your “box” is built, you can add a gate or slatted door across the front.

The bonus of open stairs? Light filters through the steps, giving the kennel a naturally bright, airy feel. The slatted effect also looks incredibly stylish.

Best for: Modern or industrial-style homes with open-tread floating stairs. Materials to use: Slim timber slats or vertical metal rods for the front panel, plywood for side and back walls.

5 — Under Stairs Dog Kennel with a Barn Door

A sliding barn door on your under stairs dog kennel is one of the easiest ways to add character and charm.

Unlike a swinging door, a barn door slides along a track mounted above the opening. This means it doesn’t eat into the space in front of the kennel — a huge advantage in narrow hallways.

It also looks fantastic. Barn doors suit farmhouse, rustic, and even Scandi-style interiors. Use natural pine, stained oak, or even paint it to match your walls.

The under stairs dog kennel door style you choose changes the whole feel of the finished product. A barn door signals warmth and personality, and your dog will learn to nudge it open in no time.

Best for: Homes with a rustic, farmhouse, or cottage aesthetic. Materials to use: Pre-made sliding barn door kit, smooth track hardware, natural wood stain or chalk paint.

6 — Under Stairs Dog Kennel with Cabinet Doors

Want the kennel to completely disappear when guests arrive? Cabinet doors are your answer.

Under stairs dog kennel built ins with full cabinet-style doors blend into your hallway or living room like furniture. Use the same door style, paint colour, and hardware as your existing kitchen or built-in storage units, and the kennel becomes practically invisible.

During the day, leave the doors open so your dog can come and go freely. In the evening, close them up for a tidy, uncluttered look.

This works especially well in modern, minimalist, or Shaker-style interiors where clean lines matter.

Best for: Homeowners who want a sleek, hidden look with no visual disruption. Materials to use: MDF shaker-style doors, concealed hinges, magnetic catches, matching paint finish.

7 — Custom Dog Kennel Under Stairs

A custom dog kennel under stairs is built specifically around your dog and your home. Nothing off the shelf, nothing generic.

A skilled carpenter or joiner can build a kennel with a built-in feeding station (with a pull-out tray for bowls), a small shelf for toys, integrated LED strip lighting, and a personalised name sign carved or stencilled above the door.

You can match the wood species to your flooring, choose bespoke handles, and even add a chalkboard panel on the side for notes or your dog’s daily schedule.

The result is a seamless, stunning addition that adds real character to your home. For even more ideas on designing a dedicated dog space, take a look at these smart dog room ideas.

Best for: Dog lovers who want a truly one-of-a-kind space and are willing to invest in it.

8 — Luxurious Under Stairs Dog Kennel

If you really want to go all out, a luxurious under stairs dog kennel is the ultimate treat for your pup.

Think memory foam orthopedic mattress, warm LED lighting on a dimmer switch, a designer arched doorway, wallpaper or tongue-and-groove panelling on the interior walls, and a monogrammed nameplate.

Some high-end builds even include underfloor heating — just a small heated mat beneath the floor panel keeps the space cosy in winter.

Add a small fitted curtain for privacy, a tiny framed photo on the interior wall, and a personalised ceramic water bowl. It sounds extravagant, but the cost of doing it properly is often less than you’d expect when built alongside other home renovation work.

This is the dog kennel under stairs design that gets shared all over Pinterest and Instagram — and for good reason. For even more luxury inspiration, these luxury dog kennel ideas are worth a look.

Best for: Pet parents who want to give their dog the very best — and love beautiful interiors.

9 — Under Stairs Dog Crate Alternative

Not ready to commit to a permanent build? An under stairs dog crate setup gives you all the comfort with none of the construction.

Choose a stylish wire crate or a wooden crate-style dog house that fits snugly into the space under your stairs. Slide it in, add bedding, and you’re done.

To make it look more intentional, hang a short curtain across the front of the opening, or add a lightweight panel that slots in when not in use. This tricks the eye into thinking it’s a built-in feature.

This approach is perfect for renters, or for owners who aren’t sure yet whether the space will work long-term before committing to a full build.

Best for: Renters, apartment dwellers, or those testing the concept before building.

10 — Indoor Dog Kennel Under Stairs with Ventilation

A fully enclosed indoor dog kennel under stairs can become stuffy and uncomfortable if ventilation isn’t considered.

Dogs regulate their temperature through panting, and a poorly ventilated kennel can become uncomfortably warm — especially in summer or in homes with central heating.

Here’s how to keep it fresh:

• Mesh or slatted doors allow constant airflow even when closed
• A small drilled vent in the back or side wall improves circulation significantly
• Avoid thick carpet on the floor — vinyl, tile, or a rubber mat is easier to clean and less likely to trap heat and smell
• LED lighting generates almost no heat, making it a better choice than halogen or bulb lighting inside the kennel

Good lighting also matters. A small battery-powered LED puck light on the ceiling of the kennel makes the space feel welcoming, not dark and unwelcoming.

Best for: All builds — ventilation should be a feature of every indoor kennel, not just this one style.

11 — Under Stairs Dog Space with a Cozy Reading Nook Combo

This is one of the cleverest under stairs dog space ideas for small homes: share the space between you and your dog.

Build the dog kennel into the lower portion of the stair space, then use the upper section (closer to the landing) as a built-in bench seat or reading nook for humans. Add a cushion on the bench, a small shelf above for books, and a reading lamp.

Below, your dog gets their own cozy den. Above, you get a quiet corner. The two spaces stack neatly without competing.

This works beautifully in homes where the under-stair space is tall enough at one end to allow a seated adult comfortably.

Best for: Small homes or open-plan spaces where every inch of space needs to earn its place.

12 — Dog Kennel Under Stairs with a Personalised Theme

Turn the kennel into something your whole family enjoys by giving it a personalised theme.

Paint the inside of the kennel in your dog’s favourite colour (okay, your favourite colour for your dog). Add paw print wall decals, a small framed photo, or a chalkboard panel on the exterior where kids can draw or write messages.

Mount a carved wooden sign above the doorway with your dog’s name. Use their collar colour as the accent colour throughout the design.

This kind of personal touch makes the kennel feel intentional and loved rather than like an afterthought. It’s also a great project to do with children who want to be involved in creating their pet’s space.

Best for: Families with children, or dog owners who love creative, personality-filled interiors.

13 — Under Stairs Dog Kennel DIY with Reclaimed Wood

For an eco-friendly and budget-friendly build, an under stairs dog kennel DIY using reclaimed or salvaged wood is a brilliant option.

Old pallet wood, barn planks, or timber rescued from a skip can be sanded, treated, and used to build a characterful kennel with a rustic finish that no flat-pack kit could ever replicate.

The key is preparation. Reclaimed wood must be:

• Sanded smooth so there are no splinters
• Sealed with a pet-safe, water-based sealant to prevent moisture absorption and odour
• Checked for nails, staples, or rough edges before your dog uses the space

The result is a one-of-a-kind kennel with real warmth and texture. Pair it with a simple rope handle on the door and a jute mat inside for a complete rustic look.

Best for: DIY enthusiasts, eco-conscious pet owners, and those on a tight budget with time and tools.

14 — Under Stairs Dog Kennel Design for Large Breeds

Large dogs need more space, stronger materials, and a wider entry point than most standard kennel builds provide.

When designing a dog kennel under stairs for a large breed like a Labrador, German Shepherd, or Golden Retriever, keep these points in mind:

• Height: Your dog should be able to stand fully upright with at least 2–3 inches to spare above their head
• Width of the entry: Should be at least 18–24 inches wide for a large dog to enter and exit comfortably
• Floor reinforcement: Use thicker plywood (at least 18mm) and add a supportive base frame so the floor doesn’t flex under the dog’s weight
• Door style: A full-height gate or barn door works better than a small cabinet-style door for large breeds
• Bedding: Use a large orthopedic dog bed or waterproof mattress — this protects joints and is easier to clean

Best for: Owners of large or giant breed dogs who want a permanent, comfortable kennel solution.

4. What to Put Inside Your Under Stairs Dog Kennel

Once the build is done, making the inside comfortable is just as important as the structure itself.

Here’s what every good under stairs dog kennel should have:

• A fitted bed or mattress — memory foam for older dogs, a washable bolster for puppies
• A spill-proof water bowl — fixed to the wall or floor if possible
• A non-slip mat or vinyl flooring — easier to clean than carpet and prevents slipping
• Soft lighting — a small LED puck light makes the space feel warm rather than dark
• One or two favourite toys — keep the space familiar and comforting

Keep the inside clean and fresh by washing bedding weekly and wiping down the walls and floor with a pet-safe cleaner every couple of weeks.

5. FAQs About Dog Kennels Under Stairs

Is it safe to keep a dog under the stairs?

Yes, as long as the kennel is properly ventilated, free of sharp edges, and large enough for your dog to stand, turn, and lie down. Never lock your dog inside for extended periods without access to water.

How big should an under stairs dog kennel be?

Your dog should be able to stand up fully, turn around in a circle, and stretch out when lying down. Measure your dog and add at least 6 inches to each dimension to get your minimum kennel size.

Can I build one if I rent my home?

Yes — use a freestanding crate or modular wooden unit that fits into the space without any permanent fixing. Some landlords will also approve minor built-in additions if asked in advance.

How do I stop the kennel from smelling?

Use washable bedding and clean it weekly. Choose easy-wipe flooring inside rather than carpet. Add a small open vent or mesh panel for airflow. A pet-safe deodorising spray used 2–3 times a week also helps keep things fresh.

Conclusion

The space under your stairs doesn’t have to be a dumping ground for shoes and forgotten clutter. With a little planning and creativity, it can become one of the most loved spots in your home — for your dog, at least.

From a simple DIY under stairs dog kennel built in a weekend, to a fully custom dog kennel under stairs crafted by a professional, there’s an option here for every home, every budget, and every breed.

Pick the idea that fits your space, start with a good measurement, and give your dog the cosy retreat they deserve. 🐾
