At South and City College in Birmingham, dozens of young people clad in hi-vis vests and hard hats are building mini-walls and plastering half-formed rooms.
Some weave in and out of stacks of bricks with wheelbarrows, while others use spirit levels to check the walls are straight and flat. In a few days time, these walls will be demolished and the plastering scraped away, for a new class to come in and try their hands.
