I'm interested in obtaining a detailed quotation for prefab houses. Specifically, it would be great to get information on various models, including their specifications, materials used, and potential customization options. I'm particularly curious about the pricing per unit, bulk order discounts, lead times, and any additional costs that may be involved, such as shipping and installation. Additionally, if you could provide insights on the energy efficiency of the houses and any certifications they hold, that would be helpful. I'm exploring options for a project and want to ensure that the prefabricated houses align with my requirements in terms of quality and sustainability. Looking forward to your comprehensive response!
