Let $\mathfrak{g}$ be a semisimple complex Lie algebra and $\mathfrak{k}\,\subset \mathfrak{g}$ be any algebraic subalgebra reductive in $\mathfrak{g}$. For any simple finite dimensional $\mathfrak{k}$-module $V$, we construct simple $\left( \mathfrak{g},\mathfrak{k} \right)$-modules $M$ with finite dimensional $\mathfrak{k}$-isotypic components such that $V$ is a $\mathfrak{k}$-submodule of $M$ and the Vogan norm of any simple $\mathfrak{k}$-submodule $V\prime \subset M,V\prime \ne \,V$, is greater than the Vogan norm of $V$. The $\left( \mathfrak{g},\mathfrak{k} \right)$-modules $M$ are subquotients of the fundamental series of $\left( \mathfrak{g},\mathfrak{k} \right)$-modules.
