Generally speaking, coffin-shaped houses are unlucky, but practice has proved that there are also mixed feelings. If you encounter a coffin-shaped house when buying a house or planning to rent it for a long time, it is best not to buy or rent it. If you really have to, you must ask the feng shui master to adjust and resolve it. Otherwise, I am afraid that there will be no peace at home and disasters will continue. Or you can customize the feng shui mascot that suits you according to your eight characters and five elements, and put it in the auspicious position of the house to promote wealth and avoid misfortune, thus bringing you good home feng shui. I suggest you go to official website, and customize your mascot for better placement.
Also, adding a small balcony or changing the pattern can be solved.
