ᐅ Experiences with Metal Carports from Poland

Hello, we are currently planning our outdoor area. We want to build a metal carport with an attached storage room. The total dimensions are 3 m (10 feet) wide by 9 m (30 feet) long, of which 3 x 3 m (10 x 10 feet) will be allocated for the shed. One side wall inside the carport should also be fully covered. We have already received several quotes from German suppliers, ranging between 15,000 and 17,000 EUR. This is too expensive for us. We live in Berlin and would now like to look for Polish suppliers. Does anyone have experience or can recommend a company? Thank you!
