Peter Robinson donned a hard hat and pulled on his tool belt as he mucked in with fellow Executive ministers on a Belfast building site.
The First Minister was one of a team of Assembly members who swapped their suits for high visibility vests to put in a shift at a social housing project.
Housing Minister Alex Attwood and Finance Minister Sammy Wilson were also grafting on the six new energy efficient homes on Madrid Street off the Lower Newtownards Road.
The build is being overseen by charity Habitat for Humanity and relies on volunteer contributions from churches, businesses and members of the public.
Mr Robinson said the day had rekindled his passion for DIY.
"I got to screw in a few things into the wall, I hope they stand up after I leave," he joked. "I certainly wouldn't put my best Delft on those shelves but I am sure someone will check it out when I've left.
"It's good to see Assembly members from various political parties working together, I wish they would do it more at Stormont."
Mr Robinson said he had not tried his hand at carpentry in years, adding: "But I have the equipment and I can tell you in my early years virtually everything in my house was hand made. It's something that I enjoyed doing and if I may modestly say I did well."
All the main parties at Stormont, with the exception of Sinn Fein, were involved in the innovative event organised in conjunction with the Assembly's engagement team.
Other MLAs on site included Ulster Unionist leader Tom Elliott, Alliance east Belfast MP Naomi Long and the SDLP's Conall McDevitt.
