I'm looking to source all necessary materials for constructing a basic home. The project includes a layout of approximately 50 square meters, featuring three bedrooms, one bathroom, a living room, and a kitchen. I need a comprehensive list of everything required to complete this structure, including but not limited to structural materials, finishing products, and utilities. Please provide details on the types of materials available, including specifications, pricing, and lead times for delivery. It's important to me to understand the options that can suit a standard build while also reflecting quality and affordability. A prompt response would be appreciated as I'm eager to move forward with this project soon.
