One issue I have with the front side of the tower is the 10 meter vertical drop from the edge of the roof to the ground. When it rains, water runs off the roof and hits the ground heavily, splashing hard in the ground and up the front facade and doors. The solution – a period perfect porch awning.
Looking at old, cast iron designs, I went ahead and designed a bracket with the same 20.6 degree tilt as the roof. Brackets are unfortunately not cast iron, but will be laser cut in 10 mm steel and then equipped with welded mounts towards the wall and the top roof boards. They are 1000 mm wide and will be mounted over the front doors, breaking the water fall from the roof while hopefully also adding a nice architectural touch to the building.
