Quality: The factory staff has been working with us patiently on our designs for months, they have re-enforced the flooring frame in order to suit the client's special request. They have paid attention to all the details we needed which is awesome. The house is also packaged nicely, thumbs up to their professional work. Installation: The factory staff have been sending us videos and instructions, this made the installation fairly easy. Customized Service: The factory has customized the inside and outside wall panels, frame colors and deck to suit my client's needs. And the house came out in such a beautiful way. Many thanks to their wonderful craftsmanship .
