You’ve seen the TikToks. A rusted-out 1990s Leyland Olympian or a sleek London-style AEC Regent gets gutted, painted sage green, and suddenly it's a Pinterest-perfect double decker bus house nestled in the English countryside. It looks like a dream. It looks cheap. It looks like the ultimate middle finger to a housing market that has basically decided millennials should live in shoeboxes for $2,000 a month.
But honestly? Most people who start these projects fail.
Converting a massive metal tube into a livable, breathable, non-molding home is a mechanical and architectural nightmare. It’s also one of the most rewarding ways to live if you have the stomach for it. Most people think "tiny home on wheels," but a double decker is a different beast entirely. You aren't just building a house; you’re managing a two-story engineering project that happens to have a diesel engine and a very specific center of gravity.

The Reality of Buying Your First Double Decker Bus House
Most people start at auctions or specialized dealers like Ensignbus in the UK. You can find a decommissioned bus for anywhere between £5,000 and £15,000. That sounds like a bargain compared to a mortgage, right? Well, the price of the bus is just the entry fee to a very expensive club.
Shipping that bus to your land can cost thousands. If it doesn't run, you’re hiring a heavy-recovery tow truck. If it does run, you need a Class 2 HGV license (in the UK) or a commercial driver’s license with various endorsements in the States to legally move it yourself. You can’t just hop in and drive your future home down the interstate like it's a Honda Civic.
Then there is the "tin pest." Buses are built to move people, not to be airtight homes. They vibrate. They leak. Windows on older buses are notorious for failing seals. If you buy a bus that’s been sitting in a damp field for three years, you’re likely buying a mold farm. You have to strip it to the ribs. Every seat—and there are usually 70 to 80 of them—has to be unbolted. It’s back-breaking, greasy, soul-crushing work.
Structural Integrity and the "Top-Heavy" Problem
The most common mistake is forgetting that a double decker bus house is still a vehicle. If you plan on keeping it mobile, you have to be obsessive about weight distribution.
If you put a cast-iron bathtub and a full bookshelf on the upper deck, you’ve just created a literal death trap. These buses are designed with a low center of gravity; the heavy engine and chassis keep the light aluminum or fiberglass body from tipping in high winds. When you start adding wood framing, appliances, and water tanks, you shift that balance.
Expert converters like those at Cezar Motors or individual renovators like Charlie MacVicar (who famously converted a 1997 Volvo bus) emphasize keeping the "heavy stuff" on the bottom. Kitchens, batteries, and water storage belong downstairs. The upstairs should be for sleeping, lounging, and maybe a lightweight workspace.
The Insulation Nightmare
This is where the romance usually dies. Buses are essentially giant aluminum radiators. In the summer, they turn into ovens. In the winter, they become walk-in freezers.
Standard fiberglass batt insulation is useless here because of the curves and the thin "walls" (which are really just 2-inch metal ribs). If you don't use spray foam insulation, you will deal with condensation. Condensation leads to rust. Rust eats your house from the inside out.
I’ve seen builds where people try to keep the original windows for the "vibe." It’s a mistake. Those single-pane windows have zero R-value. Experienced builders often skin over some of the windows with aluminum panels or replace them with double-paned RV windows. It changes the look, but it's the difference between wearing a coat in your living room and actually being comfortable.
Layout Hacks for 400 Square Feet
A standard double decker gives you roughly 400 to 500 square feet of living space. That’s more than a studio apartment in New York. The trick is the "dead space."
- The Stairwell: It's a huge waste of room. Many builders tear out the original steep, narrow bus stairs and build a winding staircase with storage drawers built into every step.
- The Driver's Cab: Don't just leave it. It’s a great spot for a "mudroom" or a dedicated utility closet for your electrical inverters and battery bank.
- The Wheel Arches: These are annoying bumps on the floor. Most people build the sofa or the kitchen cabinets directly over them to hide the intrusion.
Legal Hoops and Where to Park
You’ve built it. It’s beautiful. Now, where does it go?
This is the "hidden" struggle of the double decker bus house movement. In the UK, planning permission is a gray area. If the bus is mobile and "temporary," you might get away with it on private land. But if you're hooking up to a permanent septic tank and building a deck, the local council will likely classify it as a permanent dwelling.
In the US, zoning laws are even stickier. Many counties have minimum square footage requirements or bans on living in RVs/vehicles on private lots. You have to look for "unincorporated" land or specific "tiny home friendly" communities in places like Oregon, Colorado, or North Carolina.
Powering the Beast
You aren't plugging this into a standard wall outlet. A bus home needs a robust electrical system.
- Solar: Most double deckers have a massive flat roof. It’s perfect for 1,000+ watts of solar panels.
- Batteries: Lithium Iron Phosphate (LiFePO4) is the gold standard now. It’s expensive but light.
- Heating: Diesel heaters (like the Webasto or cheaper "Chinese Diesel Heaters") are the go-to. They tap directly into the bus’s fuel tank and provide incredibly dry, efficient heat.
Is it Actually Cheaper?
Let's talk numbers. A high-end, professional conversion of a double decker bus house can easily cost $100,000 to $150,000. If you do every single bit of labor yourself, you might get it done for $30,000 to $50,000.
It isn't "cheap" housing. It’s "alternative" housing. You are trading the stability of a traditional home for a bespoke, debt-free (hopefully) lifestyle that requires constant maintenance. You become a plumber, an electrician, and a mechanic all at once.

One specific example: The "Big Green Bus" in Sussex. It was a 1982 West Midlands metro bus. It took months of labor and significant investment to turn it into a high-end glamping stay. They had to reinforce the floorboards and install a wood-burning stove with a specific twin-wall flue to prevent the roof from catching fire. It’s beautiful, but it's a high-maintenance machine.
Crucial Steps Before You Buy
If you’re still serious about this, don't just go buy the first bus you see on eBay.
First, get a mechanical inspection. You need someone who understands heavy-duty diesel engines. Replacing a transmission on a Bristol VRT or a modern Volvo B7TL can cost more than the bus itself. If the frame is rusted through, walk away.
Second, measure your route. A double decker is roughly 14 feet 6 inches tall. Many bridges are 14 feet. If you don't plan your route from the seller to your land, you might literally decapitate your new home before you ever move in.
Third, think about water. A family of four uses a lot of water. You'll need massive fresh-water tanks (usually 100+ gallons) and a plan for "gray water" (sink/shower) and "black water" (toilet). Most bus lifers opt for composting toilets—like the Air Head or Nature’s Head—to avoid the nightmare of plumbing a black water tank.
Making the Leap
Living in a double decker bus house is about embracing the quirks. You'll hear the rain drumming on the aluminum roof like a percussion section. You'll feel the whole house rock slightly when the wind hits 40 mph.
But then there's the morning. You're upstairs, level with the trees, drinking coffee while looking out of a panoramic window that no $500,000 suburban home could ever replicate.
Actionable Next Steps
- Rent one first. Spend a weekend in a bus conversion on Airbnb. See if you actually like the verticality and the narrowness.
- Join the community. Search for "Bus Conversion" groups on Facebook or forums like Skoolie.net. The double-decker niche is small, but the people in it have already made the mistakes you’re about to make.
- Check the height. Measure the clearance of any property you’re considering. Low-hanging branches or power lines are the natural enemies of the double decker.
- Draft a weight map. Before you build, draw your floor plan and estimate the weight of every appliance. If one side is 2,000 lbs heavier than the other, your suspension will fail.
- Source your heater. Don't wait until November. Decide now if you’re going wood-burning, diesel, or propane. Each requires a different structural modification to the bus shell.
