How to design the gate of rural village entrance

Concrete should be poured under the door, there should be a lintel above the door, and door walls on both sides, leaving 20 on one side. The door width is 2.4m, and even a small car can drive in. The steel plate is enough. I buy ceramic tiles for the door lintel. They are usually 60mm tiles with edges on the top, bottom, left and right. Four pieces are about 2.4m with edges of 20cm. The top and bottom should be 10cm-15cm. The door is 2.7 meters high. Exactly the odd number. Also auspicious.

The color must not be red. Since ancient times, temple gates have been red, and government offices have been red. You can spray green with two blessing characters, or blue mountains with a golden tripod. Just two simple steel plates are enough, very thick, preferably with a threaded surface.
