We asked the experts how much it would cost to build your glass Joe cage.

What Is a Glass Joe Cage?

Expert Cost Breakdown for Glass Joe Cage Construction

1. Glass & Glazing

   High-quality tempered or insulated glass accounts for 40%–50% of total cost. Thicker glass, soundproof glazing, and Low-E coatings for energy-efficient windows will increase the budget.
2. Frame Materials

   Aluminum frames are cost-effective and durable; steel and wrought iron offer premium strength and aesthetics. Framing supports the entire structure and integrates operable windows and doors.
3. Window & Door Systems

   Custom casement windows, sliding windows, hinged doors, and sliding glass doors are core components. Sealing, hardware, and weatherproofing directly impact performance and pricing.
4. Installation & Labor

   Professional installation ensures structural safety, waterproofing, and proper operation of windows and doors. Complex designs require certified glass and window-door technicians

Final Words

Few recent objects have had as much cultural impact as Joe Goldberg’s glass box in You. Maybe Juul can put an electronic candle in the Netflix supervillains’ cage, but that’s about it. This is the star of the show and the memes are good too.
To some extent, the existence of the box is accepted and undeniable. But as season two began, questions arose about how Joe would get the cage to Los Angeles.
How did he manage to transport and assemble the glass cage without anyone noticing? Again, this appears to be the quietest warehouse building known to mankind! #YouNETFLIX #YOUSEASON2 pic.twitter.com/bQtTpkuIvL
In order to inform the public, I, your faithful servant, set out to find out how much it would cost.
I contacted nine of the UK’s leading glass box companies – they exist and are riding the wave of high quality greenhouses. You know, after everyone gets tired of the white PVC greenhouses with spikes on top and they start designing the mainline flat design.
This is the standard I set in very serious emails. Please note: I don’t want to look like a real killer, but the company must be clear about my goal.
As you can see, I have a hard time finding photos without people. Shortly after sending the message, I realized that I should have looked harder. But, nevertheless, the bait was set. It’s time to sit back and wait.
I received responses from several people who clearly wanted nothing to do with this whole enterprise. “We’re not offering anything you asked for,” one person told me very animatedly on the phone. Another person simply emailed back and said, “Sorry, we can’t help with that.”
Initially another company showed interest, a guy called Darren came back to me and said, “Like you said, it looks a little strange, but please send over the pictures and specs you have and I’ll take a closer look and get back to you. The boss discussed it.” In the end, Darren wisely decided that he was too busy with other projects to give me an estimate.
However, one will get bitten and I can tell you that making your own glass box (from the hit Netflix series You: You) will cost you at least £60-80,000.
Paul, a salesman at Vivafolio, a company specializing in “glass architecture,” initially called my query “a really scary question!”
On its website, Vivafolio promises to “transform your dark and dreary spaces with custom ceiling lights or stunning atriums, or open up entire areas of your home to the outside world with folding sliding or sliding doors. Viva uses glass and the only limit when using aluminum is your imagination, which allows us to create a range of truly unique conservatories, conservatories and glass extensions.”
Luckily, Paul gave me an answer that delivered on the site’s promise: “The only limit to Viva’s use of glass and aluminum is your imagination.”
“But if I were to build this room to the required specifications, it would probably cost between £60 and £80,000. Possibly more, depending on the location and whether you need a separate air source.
“I would use clear acrylic plastic, bulletproof, 32mm thick. One person won’t break it.
“I would also consider a lock that is impossible to pick, such as the Avocet series, which is almost impossible to open without a key.
“The floor is steel mesh, poured with high quality concrete and coated with a durable resin (so they can’t dig their way out)!
“I would make the steel corners and the main and secondary frames from stainless steel, which is durable and will not rust over time.
The brain is filled with this information – bulletproof acrylic! No one can dig up this floor! The frame does not rust over time! A lock that cannot be picked! “I was delighted and asked Paul if anyone had ever asked for something like this.
“However, I think that if someone were building such a facility, they would build it themselves, so as not to alert the authorities!”
