I'm looking to gather more detailed information about your prefab houses. Specifically, I'd like to know about the different models you offer, their pricing structures, and any customization options available. It would be great to understand the materials used and the energy efficiency features included as well. Additionally, could you provide insights on the lead times for delivery and installation? I'm also interested in any warranty details you have and whether you offer after-sales support. Any brochures or catalogs you can share would be super helpful for my evaluation. Thanks!
