In Hong Kong, most interior design packages include the blueprint of floor patterns, layouts, lighting plans, 3D rendering plans, amendments, project management and inspection. The price of interior design packages depends on the size of your house—for example, a package for a 400-square-foot interior design costs around HKD250k to HKD400k.
If you need the home design blueprint only instead of the interior design package, you might need to consult your interior designer and get a more accurate quotation.
