I'm looking for a detailed quote for constructing a 3-bedroom house that can comfortably accommodate either a king or queen size bed in each bedroom. The design should optimize space while ensuring comfort and functionality. Please provide information on materials, estimated timelines, and any additional components like plumbing, electrical installations, and interior finishing. Additionally, I'd appreciate if you could include options for energy-efficient designs and sustainable building materials, as I'm keen on reducing the overall environmental impact of the construction. It would be great if you could also highlight any warranties or post-construction support services you offer. Looking forward to your prompt response with the complete breakdown of costs involved.
