    It is proposed to create a storage room utilizing the roof void above an integral garage. The span is 9' (2740) Plan to use 6x2 (47x150) rough sawn treated timber joists hung from wall plates at 450mm centres with 1 (offset) row of noggins. (I've checked these against tables and this size timber seems to be fine for this span).

    Wallplates to be anchored by concrete/Thunder/Lightning/Atlas/Tapcon bolts into red 4" brick.

    The dead load will include 2 x 12.5mm fireline board. Flooring will probably be 18mm chipboard. (other, cheaper suggestions welcome).

    I am struggling to find the correct diameter, length (130mm?) and spacing for the anchor bolts.
