One item I love to focus on when building or remodeling a home is the lighting. Lighting can change the look of a house.
There is no one-size-fits-all answer when it comes to lighting budget for a house. It will depend on such factors as the size of the house, the types of lighting you choose, and the quality of the materials. A good rule of thumb is to allocate around 2% of your total building costs towards the lighting budget.
