FAQ: Your questions about renovating an old house with an architect
Is an architect required to renovate an old house?
Regulations do not systematically require the use of an architect for the renovation of an old house. However, their expertise becomes mandatory if the work modifies the structure of the building or exceeds 150m² in surface area. Furthermore, in the case of a complex architectural renovation or in a protected area, calling on a heritage architect is highly recommended. These professionals master traditional techniques and the regulatory constraints specific to old buildings, thus ensuring the preservation of the authenticity of your property.
How much does an architect cost on average for a complete renovation ?
The cost of a DPLG architect for a renovation project generally varies between 8% and 12% of the total cost of the work. This percentage depends on the scope of the project, the technical complexity, and the level of service chosen. For a complete renovation project management mission, including design, permit application, and site monitoring, expect to pay an average of 10% of the renovation budget. Some architects also offer partial missions with fixed-price or hourly rates depending on your needs.
What is the typical duration of a renovation project with an architect ?
The transformation of an old house generally lasts 8 to 18 months. This duration is broken down into several phases: 2-3 months for studies and design, 2-4 months for administrative authorizations, and 4-12 months for the work depending on the extent of the renovation of the old building. The schedule can vary depending on the complexity of the project, regulatory constraints, and the availability of craftsmen specialized in heritage restoration.
Can the architect help me obtain financial aid for my renovation ?
An architect specializing in the renovation of old houses is fully familiar with the various grant programs available. They can assist you in obtaining grants from the ANAH (National Agency for Housing and Housing), local authorities, or the Fondation du Patrimoine (Heritage Foundation). Their expertise in architectural renovation also allows them to optimize your project to maximize grants while meeting the required technical and heritage criteria. This assistance can significantly reduce your final renovation budget.
How to check an architect’s references and qualifications ?
To choose an architect skilled in renovating old buildings, start by checking their registration with the French Order of Architects and their specific qualifications (heritage architect, DPLG architect). Examine their portfolio of similar old house renovation projects. Don’t hesitate to contact their previous clients and visit their completed projects. Reputable architects generally have a strong network of artisans specializing in heritage restoration.
What should I do if I disagree with my architect during the work ?
In the event of a dispute during your renovation project, begin by engaging in constructive dialogue with your architect, referring to the initial contract. If the disagreement persists, you can seek mediation from the Council of the Order of Architects. DPLG architects are required to carry professional insurance to protect you in the event of a problem. In more complex situations, an architectural renovation expert may be appointed to mediate the dispute.
Does the architect handle the procedures with the Bâtiments de France ?
Yes, an architect specializing in heritage restoration handles all administrative procedures, including relations with the Architects of Buildings of France (ABF). Their in-depth knowledge of heritage constraints makes it easier to obtain permits for your old house renovation. They know how to adapt your project to the requirements of protected areas while preserving your objectives for the transformation of the old building.
Can I hire an architect just to design the plans ?
A design-only mission is possible and represents approximately 30% of the fees for a complete renovation project management mission. The architect will create the plans, development proposals, and the building permit application. However, for a complex architectural renovation, it is recommended to opt for a complete mission that includes site supervision to ensure consistency between the design and completion of your renovation project.
