We discuss building models for nucleon generalized parton distributions (GPDs) H and E that are based on the formalism of double distributions (DDs). We find that the usual "DD+D-term'' construction should be amended by an extra term, generated by GPD E(x,\xi). Unlike the $$D$$-term, this function has support in the whole -1 < x< 1 region, and in general does not vanish at the border points|x|=\xi.
