Quote: interior architecture
E.g.: 3D plans for an apartment renovation, optimising an existing layout
Want to change room distribution or use? Describe the problems, overall allowance and items to retain. Commission a defined service: layout studies, contractor documentation and construction support are not automatically bundled in every offer.
Check professional and scope
Guichet.lu describes independent practice and the specific temporary cross-border regime. Request evidence appropriate to the professional's situation, applicable OAI registration and insurance covering the brief. A portfolio does not establish entitlement to perform every offered service.
Start with a realistic brief
Specify occupants, activities, storage, equipment, access and total allowance including works and furniture. Assign survey and included existing-condition checks. For structure, services or permissions, identify necessary specialists and procedures before adopting a solution.
Distinguish images from execution documents
Specify options, dimensioned drawings, named materials, details and specifications at each stage. A 3D image supports discussion but does not replace verified measurements or technical studies. Agree your decisions and included revisions before the next phase.
Define contractor enquiries
Check whether preparing requests, answering contractors and comparing bids are included. Identify provisional quantities and open decisions. Assign review and approval of material substitutions before ordering.
Choose the support required
OAI also lists execution supervision and completion assistance, so interior architecture is not inherently limited to design. Check actual commissioned tasks, meetings, reports and boundaries. A design-only service should provide a usable handover to those continuing the project.

No grant is deducted from the budget shown here. If a quote mentions support, request the exact scheme and confirmation of your eligibility before including it in financing.
Frequently asked questions
Is site support always included?
No. It can be commissioned but must be defined in the contract.
Does a 3D image permit work to start?
It does not alone replace verified execution documentation.
Who checks a load-bearing alteration?
Identify a competent professional, structural study and required procedures rather than relying on the service name.
Does a percentage guarantee a better price?
No. Compare base, tasks, projected amount and effect of changes.
