In this work, we investigate the influence of interlayer distance in a heterostructure containing both Kondo effects and short-range magnetic correlations. Our proposed heterostructure comprises three coupled square lattice layers. The first layer is governed by the Kondo-Heisenberg lattice model involving f- and d-electrons, which interact via Kondo and Heisenberg couplings, JK and JH, respectively. The other two layers consist of non-interacting itinerant electrons, where coupling with the first layer is determined by two perpendicular hopping parameters. We find that varying the interlayer couplings induces electronic dynamics at the interface, altering the behavior of mean-field parameters describing the Kondo effect and short-range magnetic correlations. The system's temperature - interlayer hopping parameter phase diagram exhibits a sequence of discontinuous and continuous transitions. In the cases, |JK|<|JH| and |JK|>|JH| rich phase diagrams are found which include Kondo, ferromagnetic and antiferromagnetic correlations. Our work provides insights into hosting Kondo correlations in heterostructures.
