Design Considerations
When planning a 4-bedroom kit home, consider:
- Master suite location — separated from other bedrooms for privacy, or grouped for family functionality
- Living zones — open plan vs formal/informal separation
- Garage integration — attached double garage adds $25,000-$40,000
- Outdoor living — alfresco areas extend usable space without adding build cost
Most 4-bedroom plans can be modified. Common changes include adding ensuites, repositioning the kitchen, or extending the garage.
