Raised/elevated deck

The finished deck must be at least two brick courses below damp course level.

We recommend that at least half the length of the post is sunk into the ground and fixed with concrete. (For elevated decks higher than 600mm consult a builder.)

As with ground level decks, we recommend joists are spaced at maximum 400mm centres.
Structural posts should be positioned no more than 1800mm apart.

Elevated decks can be free standing or have one or more sides attached to a wall/side of house.
Use a joist and spirit level to mark the joist/ledger height onto wall.
To give added structural stability and support. fix two joists together using coach screws to form the joist ledger and fix to wall using wood to masonry fixings.
When attaching a deck to the side of a building, the wall plate/ledger is fixed to the masonry to support the joists. Keep the wall plate/ledger off the wall approximately 10mm by packing the wall plate or using washers on the wall plate fixing so as to allow water running down the face of the brickwork to pass behind, rather than on top of the wall plate. Alternatively, if fixing the wall plate directly to masonry, use a metal flashing keyed into the mortar joint of the brickwork using 150mm lag/anchor bolts or frame fixings.
Mark the depth of a joist onto the structural post and fix joists/beams either side using 150mm landscape screws.
These beams accommodate the frame's joists. Fix the joists to the beams by skew-nailing or use seismic/hurricane ties. For additional strength, noggins (offcuts of joists) are then fixed at 90º to the structural joists.
To fix joists to the joist/ledger use joist hangers.
