Mexican designers show that Trump's proposed $25 billion wall could take 16 years to build

Less than a week after his inauguration, President Donald Trump says he will make good on his promise to build a wall along the US-Mexico border and block illegal immigrants from entering the country. 

"Big day planned on NATIONAL SECURITY tomorrow. Among many other things, we will build the wall!" he tweeted Tuesday. But what would Trump's proposed wall look like in reality?

Mexican architects from Estudio 3.14, a design firm based in Guadalajara, imagined a hot pink border that stretches 1,954 miles, called the "Prison-Wall."

The renderings are meant to show the impracticality of building the wall, designer Norberto Miranda told Business Insider. He says the border likely wouldn't foster positive relations with Mexico, and the country's rolling mountain ranges would make construction difficult.

As many others have pointed out, the wall would also be expensive, and Mexican President Enrique Peña Nieto said his country would never pay for it.

CNBC's Kate Drew wrote that the construction would cost the US government $15 billion to $25 billion. Maintenance and hiring 21,000 agents as border patrol would cost an additional $2.1 billion per year, according to CNBC and an analysis by Politico. Estudio 3.14 designed the renderings around these estimates.

Here's what Trump's wall could look like:

The designers imagined a pink wall, since Trump has repeatedly said it should be "beautiful."

The design was also inspired by the work of renowned Mexican architect Luis Barragán, who is famous for his blunt, stucco walls and use of bright colors.

Stretching from the Pacific Coast to the Gulf of Mexico, the wall would separate the southwest US from northern Mexico.

The wall would include a prison for immigrants, holding up to "11 million people who Trump plans to deport," Miranda said.

Another part would feature a manufacturing plant, where the prisoners would work to maintain the wall.

According to the design, Americans would enjoy a shopping mall that's built into the wall, too.

The mountain ranges along the Mexico-US border would make the wall's construction nearly impossible and costlier, Miranda says. The areas without existing fences are the most dense and arid, so taking those physical challenges into consideration, it would take 16 years to build.

The proposed divider is a "megalomaniac architectural proposal," he says.
