One view is that there is no bad effect. Because most people will face such a situation, it will not affect your marriage.
There is also a view that from the perspective of geomantic omen, the balcony is facing the lamppost. Because the light pole means "support" and support means "help", the pattern of having helpers is naturally beneficial to home feng shui. However, if the balcony is facing the lamppost, it means that the power of "helping" is leaked, making it impossible to help. Therefore, if the balcony at home is facing the lamppost, you can plant some plants on the balcony or living room to resolve the suffocation.
Therefore, whether to take action on the problem that the balcony is facing the lamppost may depend on your personal beliefs and needs. If you want to plant plants on the balcony to solve suffocation, you can consult a professional gardener or feng shui master.
