A Madame Tussauds waxwork figure of the US President was paraded outside the future home of American diplomats in Britain in a stunt on Friday morning.
It came after Mr Trump cancelled plans to open the building in Nine Elms, south London.
Delighted construction and office workers posed for photos with the 6ft Trump model next to the nicknamed 'Giant Cube' building on the banks of the River Thames.
Clad in a trademark black suit, white shirt and long red tie, waxwork-makers Madame Tussauds said they took their replica down to the Nine Elms site for "a bit of fun".
"We woke up to the news as everyone else did in the country and thought it would be a bit of fun," the attraction's Claire Treacy said.
She said the company had taken a jovial spin on Mr Trump's announcement he was pulling out of opening the new home of American diplomats in Britain.
Sky's Tom Rayner said contractors at the embassy were "pleased to see him".
But he added staff were nervous the delicate model might get broken.
Mr Trump said he was cancelling the forthcoming trip because his predecessor Barack Obama sold the old Grosvenor Square embassy for "peanuts" and built the new one in an "off location".
Despite the claims, it was the George W Bush administration that initiated the building's move to Battersea.
Battersea Labour MP Marsha De Cordova said Mr Trump was "scared to come to London because of all the peaceful protests he will face".
