The DIRTT face-mount tile or Solid Walls are parametric in size and universally and horizontally support all new and legacy furniture, fixtures and equipment. Each wall side performs and is aesthetically independent of the other. Tiles can be on or off-module. A/V can be elegantly integrated inside or seamlessly mounted on the face of the Walls. Post-move-in the Wall cavities are accessible for maintaining, replacing or adding technology, plumbing or electrical outlets.
