Received the design, your booth open 2 sides please confirm us coz I’m not sure the design had open 2 sides. Please reduce side wall which wall side is close to the neighboring stand. Because reference regulation fitting we allowed back wall height 3.5m(H) if you need to build the structure is higher than 3.5m(H) must be setback from neighboring stand 1 m. For clarify please see image below. (Red line)
