Hello everyone,
after searching for a suitable canopy for our entrance area, I keep coming across canopies made of concrete. In a new building, something like that can of course be integrated without much effort, but we are not building new, rather we have an existing building. Now the question for me is whether it is still possible to implement it afterwards here.
To clarify exactly what I have in mind, I have included an example picture for you.
Regarding the dimensions: The entrance area is 1.40 m wide. Ideally, the canopy should also be this wide. In length, I was thinking about 1.5 - 2.0 meters.
I am not a professional and not a craftsman but I am handy and skilled, i.e. I do not necessarily need a specialist company but just help on how I can implement it so that it also holds and does not collapse in severe weather or under snow load.
I come from Saarland, i.e. snow is not abundant and also not really often in our "winter".
I had imagined now that I would make the vertical support out of concrete formwork blocks with reinforced steel so that I can create a connection to the base. The base is an extension floor in the basement, i.e. a concrete basement ceiling. The concrete formwork blocks can be plastered later accordingly and through a coating/spatula technique I am sure you can get a concrete look? (Alternatives are of course welcome). I had thought about whether I could perhaps build a shuttering myself in this dimension but I am not sure whether it would withstand the pressure from the concrete. Here too I would appreciate ideas/instructions on how it could be implemented.
So that the "lid" of the whole construction holds and gets a stable bond with the house, I thought that I could perhaps insert slots every 50 cm along the length of the roof in the wall and insert steel beams into the wall there so that the weight is absorbed. Then stiffen everything with steel, put shuttering underneath and support it accordingly and then pour the lid out of concrete. The sealing on the wall with appropriate sealant and a slope for water drainage.
So my plan
Now I hope for your input and ideas whether it is feasible and how I can best implement it.
It would also be helpful to know how thick the ceiling must/may/should be, which beams have to/should be inserted so that it holds. I do not have a structural engineer on hand who could calculate something for me beforehand.
Thanks in advance for your help.
Best regards
