Estudio 3.14's vision for Donald Trump's proposed wall along the Mexico-US border.

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.
