<p>A timber floor panel (2) having parallel outer joists (3) and intermediate joists (4), where a top decking panel (5) covers the joists. Cross-members (6) transverse the underside of the joists for reception of a ceiling. The outer joists (3) may be more substantial than the intermediate joists (4), which in turn, are more substantial than the cross-members (6). The exposed edge of the joists may be covered by a batten and the ratio between the depth of a joist and spacing between joists is 1:2 to 1:4. Free ends of each joist forming a panel may be supported by a support structure (fig 2, not shown).</p> |
