How dangerous is to plant Pinus pinea 3m (10ft) from the house?
The house has only one floor, so I gather the crown will not interfere with walls and roof.
The situation would be similar to the one pictured here:

I don't know that I'd consider it dangerous to plant the tree that close, but from a design perspective I wouldn't do it with any large tree - the tree will eventually dwarf the house and the effect will not be pleasing to the eye. Seeing that the tree is also a pine, I'm assuming that as the tree grows it will become wide enough to probably interfere with access to the outside of the house itself unless you prune the lower limbs (perhaps this species, which I'm not familiar with, is different in that respect?). That's just added maintenance which is easy to avoid by moving the tree farther from the house, if that's possible with your site.
Pines also drop needles, of course, annually and you'll either have to clean your rain gutters fairly regularly or clean off the leaf-guards that may be on top of the gutters (needles are notorious for piling up on leaf guards rather than rolling off of them). Again, more maintenance.
As you might guess, I'm REALLY into having a no-maintenance garden.
From a "danger" perspective, from what direction are the prevailing winds? Would it be possible at a (much) later date for the wind to blow a branch - or even break the tree off at the trunk - onto the house during a storm? I recently had two large, mostly dead ash trees (victims of Emerald Ash Borer) removed to the immediate west of my house because our storms come from the west and I didn't want a large branch to land on or pierce my roof.
