Readers are discussing satirical designs created in response to Donald Trump's presidency – including a flat-pack border wall and a logo based on the Nazi swastika – in this week's comments update.

Büild a wåll: commenters are reacting to a spoof of an IKEA flat-pack furniture kit, which demonstrates how to cheaply build Donald Trump's proposed Mexican border wall.

"Let's hope Trump doesn't use a nuclear launch key instead of the Allen key," wrote Geoofbob.

But some didn't see the funny side. "The more people come up with solutions for this wall, the less likely it will be cancelled," wrote regular commenter H-J. "They're even trying to help him realise it on a shoe-string budget."

Logo no-go: Tucker Viemeister's alternative logo for Trump based on Nazi insignia led to readers sharing other facist-style logos in the comments, and drew criticisms for being too simplistic.

Stirling v Mies: the other talking point this week was Mies van der Rohe's unrealised tower for the City of London, which has been revealed in detail for the first time.

Readers who prefer its design to the building that was eventually built for the site – James Stirling's postmodern No 1 Poultry – expressed regret.

"Can't we just demolish that ugly Pomo building and build this beautiful Mies van der Rohe masterpiece?" one user wrote.

"A painful reminder of how it could have been," wrote Guest. "London's greatest missed opportunity? I think so."

But not everyone was disappointed with how things turned out:

So wrong it's Wright: an unbuilt chapel by Frank Lloyd Wright has been realised in these colour visualisations by architect David Romero, but some readers are glad it never became a reality.

"Very unlike Mr Wright," wrote Joel. "I'm rather glad it wasn't built."

"The images don't do it justice – very flat plasticky feel to it," wrote Ngon. "However, the effort of showing unbuilt work should be appreciated!"

Not all responses were negative:
