When designing the floor plan for your home, you need to include all doors and windows, complete with accurate dimensions and the planned opening direction. This is important as the openings will play a major role in structural calculations for the building. Your benefit: this will allow you to plan each room with your chosen furnishings. Because floor plans are not just important to prepare for the actual construction of the house, they also provide the framework for planning the interior design.
Important: If you wish, you can plan your house and draw up the floor plan yourself. To ensure the accuracy of your house building plan and to design a perfect floor plan, an architect will then liaise with a structural engineer to finalise the floor plan draft. The structural engineer needs to calculate and approve the bearing load for the supporting walls.
