Here is a recent Awning installation that was carried out in Midhurst, Surrey.
Commonly, when installing on bungalows we use spreader plates to bring the fixings away from the top course of bricks.
Awnings are quite heavy and can create a lot of leverage when the wind blows under them. If you mount the Awning into top courses of bricks the bricks are likely to lift or pull away from the mortar. As long as you have 5 courses of bricks above the fixing position then you should be fine to mount the Awning. Spreader plates simply remove the need for fixing into the top bricks and brings several fixings down the wall into stronger brickwork.
This is a full cassette Awning that has a width of 4m and a projection of 2m. The images were taken prior to the electric being finalised and as such, the cable you see on the right would no longer be present.
