About After the initial consultation service, if you wish to entrust us with a more in-depth development towards the concrete realization of the interior design of your house, we will need to sign a contract. The fee will be calculated as 10% of your project budget. The entrusted work will include on-site surveys, dimensional measurements, data collection, floor plan configuration, confirmation of design guidelines and styles, 3D drawings, construction drawings, and the preparation of project budgets.
