All column, concrete, planes and low rise wall pieces are not connected. I have positioned them for example purposes as shown in renders. Clone and manipulate each piece to fit your landscape needs. Iron pieces are a cutout used on a single plane for reduced poly count. Total scene has 810 polygons made up of 8 wall samples I had positioned for rendering purposes. Raytrace option suggested for iron shadow casting. May require adequit equip. to render under high detail scenes.
