Why do interior designers in Diamond Bar have an hourly fee and a markup on the product?

The markup or cost-up covers the whole process of producing the orders to ensure the client's satisfaction

Why do I need to hire an interior designer in Diamond Bar if I already have an architect?

There is a big difference between the work of an architect and interior designer. An architect works on the structure and the design of the building. They do not work on the interior details like the design of the living room, kitchen, bathroom. Nor do they pay attention to the furniture, color and design motif of the walls, flooring specifications and what wall and window treatment to be used. That is basically the function of the interior designer. Designers create the master plan for the interior of homes that can be developed in stages, depending on the budget of the client.
