Commercial architecture project in Paris: How it works

Your fit out project begins with personalised specifications based on your needs, brand or business identity and initial concept.

The point here is for the architect to provide results exactly matching your functional needs and the general expectations for a professional workspace, while staying within the estimated budget.

From the architect’s suggestions and the expression of your needs, we can finetune the specifications for the commercial project progressively before executing the works.

First step: initial interview

  • In this first meeting, you share your needs and expectations for your commercial architecture project to the architect, whether you are looking to renovate a shop, hotel, restaurant, offices or any other type of public space.
  • You inform your architect about your personal taste in decoration and your functional needs. Example of Q&A for an office: what are the typical interactions between employees and business units? Is there a need for meeting spaces? Are there regulations for safety or sanitary standards to comply with? Answering these questions will allow the architect to understand the full scope of the project in order to create a space that is completely synced with your business.
  • During this first meeting, the architect also evaluates the potential of the raw space, its qualities (light, space reorganisation opportunities) and constraints (load bearing walls, cables/connections, building standards). - You will get some ideas on the fit out and the decoration on the spot.
  • At the end of the meeting, you define together the next steps of the mission and agree on your architect’s involvement for the rest of the project.

Second step: specifications of your commercial project

During this stage of the project, your architect will collect all documents required prior to starting any construction or renovation:

  • From a site measure and based on your needs, the architect will provide you with fit out proposals in the form of sketches.
  • Once you agree on the main direction of the project, the architect produces complete specifications that will guide the renovation work: proposed floor plans, elevations, sections, electrical plans.
  • She/he will take care of applying for required building permits to relevant public bodies: city councils, reduced mobility organisations, safety commissions, administrative offices.
  • The architect will select furniture and materials (tiles, floorings, fittings).
  • After drafting the project’s specifications (masonry, floor coverings, plumbing work), a request for quotes is sent to trusted contractors and suppliers in the Paris area. Contractors will be selected depending on the specifics of your project. The architects is able to read, understand and analyse quotes and negotiate when needed.
  • At the end of the specifications phase, you can decide to continue working with your architect during the execution phase. She/he will then supervise and coordinate the works.

Third step: works supervision and coordination

  • The architect is in charge of the planning and coordination of all works. It is her/his responsibility to coordinate with the several suppliers, contractors and craftsmen.
  • The architect will control the quality of the works and ensure that they are in compliance with the specifications.
  • Architects are responsible for organising regular meetings in order to keep you updated of the progress and respect of deadlines.
  • Also in scope of this stage: choice of furniture and of decorative objects.
  • Once the execution of the works is complete and all contractors have delivered according to specifications, the architect takes care of the final touches before you can open or reopen your shop, restaurant, hôtel or office.
