A concealed suspension ceiling assembly with simplified support structure for closely spaced ceiling tiles is described. The ceiling tiles are kerfed and mounted on framing members suspended from a supporting grid. V shaped torsion springs engage hooks on the framing members and extend upwardly through slots in main tees in an intersecting grid of main tees and cross tees. A tool is inserted in the reveal between adjacent tiles to raise and lower a selected tile. Tiles are lowered in predetermined sections to permit access to the space above the suspended ceiling and also to permit repair or replacement of individual tiles.
