A 30x45 plot will have an area of around 1350 square feet, which can be used for building a large single storey or a duplex home. A 30×45 house plan north facing will give you ample space to work with when designing the layout, ensuring your rooms have good proportions and there is ample open space for living, dining, cooking and parking. Balconies, utility spaces or a small garden may also be incorporated into the design, as indicated by local building codes. This lot size can provide for an ideal compromise of affordability, comfort, and modern living with proper planning.
