Doors & Windows

A significant cost and design decision affecting security, light, and ventilation.

Used for

  • External entry points
  • Internal room doors
  • Natural lighting and ventilation

Quality considerations

  • Confirm frame material (steel, aluminium, timber) suits the application — external doors generally need more robust framing than internal ones.
  • Order to confirmed final opening sizes after walls are built, not from early drawings alone, to avoid costly refitting.

Common mistakes

  • • Ordering before final wall openings are confirmed, leading to poor fit.

Priced per unit; material, size, and glazing type are the main cost drivers.
