What measurements matter for an attic staircase?

Question

Accepted Answer

An attic staircase has particular requirements:

**Key measurements:**
- **Deck opening:** Length and width of the opening determine which stair shape is possible. For a comfortable staircase, the opening should be at least 2 square metres.
- **Floor-to-floor height:** Distance from the floor of the lower storey to the attic floor
- **Deck thickness:** Affects the overall construction
- **Headroom:** A minimum of 2 m clearance must be ensured

**Important:** HTS does **not build loft ladders or fold-down stairs**. For attic access, HTS manufactures full solid wood staircases -- provided the deck opening is large enough. For tight spaces, a winder stair shape or a more compact design can be chosen.

When planning a loft conversion, HTS recommends sizing the deck opening generously from the outset so a comfortable staircase is possible.
