Is the 7-meter-wide balcony of the first-floor bungalow in rural areas firmly extended to 2 meters?

Balcony expansion must consider the bearing capacity, must start from the grassroots, and must choose reinforced concrete when selecting materials, so as to achieve better stability and be very safe. It is better to install two pillars to enlarge the balcony, which will be more secure by comparison.

I suggest that you can directly find a professional construction team, ask them for details, understand the detailed construction methods, and then buy building materials according to actual needs.
