transform the existing staircase into a continuous mediterranean sculpted plaster volume preserve the overall stair location proportions and room layout but completely rework the stair guard and ceiling geometry into one unified carved gesture design direction replace the existing curved guard and angular ceiling plane with a continuous flowing plaster sweep eliminate the sharp triangular ceiling apex extend the curve upward so the guard transitions seamlessly into the ceiling the form should read as carved from a single mass no hard corners or visible framing logic smooth elliptical curvature soft transitions material warm mineral lime plaster finish soft off white with subtle tonal variation matte texture with gentle light movement no glossy paint lighting concealed linear led integrated at the top of the curve soft downward grazing light to emphasize sculptural depth warm 2700k tone details remove bulky base elements at stair bottom simplify edges and eliminate visual breaks maintain minimal restrained mediterranean character calm architectural monolithic atmosphere ibiza contemporary villa sculptural quiet luxury hand formed plaster volume natural light interacting with curvature keep the rest of the interior intact and refined exaggerate the continuous plaster sweep so the stair reads as a carved architectural void completely eliminate the triangular ceiling point and replace it with a smooth elliptical ceiling transition the curve should extend further into the ceiling mass and feel monolithic and sculpted from one continuous volume remove the visible cylindrical base at the bottom of the stair and integrate the base into the plaster mass so it feels carved not added increase contrast in lighting so the plaster surface shows stronger shadow and depth from grazing light
