How much does it cost to build a country villa in the countryside?

The basic civil engineering (blank) costs 600* 400, which is about 250 thousand. According to the local material price, there should be a fluctuation of 30,000-40,000, with a minimum of 22 and a maximum of 28 ordinary aluminum alloy windows 1.5-2W explosion-proof glass 2-3w. The area of tempered glass will be about twice that of landscaping. Of course, you can't grow any high-end plants. The price difference is too big. General foundation decoration: 200,000 yuan including all imitation porcelain floors. Brick (good quality non-brand name) stairs, kitchen, bathroom, basic facilities, simple doors, simple background walls, local decorative cabinets ... it's almost enough to live in, but it doesn't feel extravagant.
