Starting from the Gaia DR3 HR diagram, we derive the star formation history(SFH) as a function of distance from the Galactic Plane within a cylindercentred on the Sun with a 200~pc radius and spanning 1.3~kpc above and belowthe Galaxy's midplane. We quantify both the concentration of the more recentstar formation in the Galactic Plane, and the age-related increase in the scaleheight of the Galactic Disc stellar component, which is well-described bypower-laws with indices ranging from $1/2$ to $2/3$. The vertically-integratedstar formation rate falls from $(1.147 \pm 0.039)\times10^{-8}\,\text{M}_{\odot} \text{yr}^{-1} \text{pc}^{-2}$ at earlier times down to $(6.2\pm 3.0) \times10^{-9}\, \text{M}_{\odot} \text{yr}^{-1} \text{pc}^{-2}$ atpresent times, but we find a significant peak of star formation in the 2 to 3Gyr age bin. The total mass of stars formed per unit area over time is $118.7\pm 6.2\, \text{M}_{\odot} \text{pc}^{-2}$, which is nearly twice the presentstellar mass derived from kinematics within 1~kpc from the Galactic Plane,implying a high degree of matter recycling in successive generations of stars.The method is then modified by adopting an age-dependent correlation betweenthe SFH across the different slices, which results in less noisy and moresymmetrical results without significantly changing the previously mentionedquantities. This appears to be a promising way to improve SFH recovery inexternal galaxies.
