Portal Arcade Run

Colonial portal arcade as one connecting run: a 4 m bay of a round stone arch on 0.8 m square stuccoed piers, 5 m to a moulded cornice with a flat parapet above, a vaulted walkway 3 m deep behind and a flagged floor at 0.15 m.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
