Indeed, I need to add a way to pass a1 in the constructor.

Yes, but in addition to that, the concern is:

Yes because I use: node >::operator new ()

Given: new block >(/* a1 */) I still don't see how the 'new block(...)' is going to use 'a1' for the block allocation. I can see how it could not use '::operator new(std::size_t)' if you have overloaded operator new for block, but at that point, you still wouldn't know 'a1' (though you do know the type 'A'). Just using A{}.allocate(...) is not sufficient, especially if A is a stateful allocator. i.e. A might not even be default-constructible: the only way to construct an A instance might require providing that state (a1) (or copy-construct given an existing A instance).
