Hello!
Planning to build a balcony so that we can enjoy the evening sun. The dimensions will be 140cm deep and 500cm wide.
I don't want any posts down to the ground and preferably avoid diagonal braces downward as I believe it can lead moisture into the facade. Unfortunately, the floor joists run the "wrong" way, so I can't extend any beams there. So what to do?
Extremely grateful for any answers.

If it is not possible to insert beams into the joist, only some form of console solution remains. How such a solution can look depends entirely on how the house is built, i.e., structural system, facade material, heights, etc.
It is wooden cladding. Inside there is 1 inch tongue-and-groove, air gap, and then 2 1/2 inch tongue-and-groove timber.
I'm considering whether it's possible to build a frame in laminated timber and then use tie rods.
Has anyone done something similar?
And thanks for the answer.

Companies that specialize in balcony renovations in older apartment buildings often use a method that involves heavy steel profiles attached vertically to the facade at its full height. The balconies are then hung on these profiles and supported by diagonal braces also attached to the same profile.
Since you have a wooden plank house, it would be relatively easy to use a similar method, but more adapted to the specific situation. I could imagine L or U steel profiles screwed into the plank frame with through bolts. In them, you attach glued laminated beams as the balcony base, secured with steel hanging rods. Alternatively, you use underlying diagonal supports in glued laminated timber. It's a matter of practicality and aesthetics. Steel is best for tensile forces and wood for compressive forces. You can also use glued laminated timber bolted to the facade, but then you cannot have hanging rods. Designing and constructing the balcony is not for amateurs, given the appearance and safety considerations. However, I don't think it should have to be extremely expensive to build.
