Agency

Founded in 1985, Muse Interiors operates as a general contractor specializing in high-end apartment renovations in Paris.

We manage the entire project:
design, cost estimation, coordination, execution, and turnkey delivery — under a single contractual commitment.

Our mission is straightforward:
to provide our clients with a single point of contact, responsible from start to finish, ensuring quality, deadlines, and overall coherence.

The Role of a General Contractor

Within the framework of a full apartment renovation in Paris, we assume:

• Full responsibility for the project
• Coordination of all trades
• Technical and administrative management
• Budget control
• Adherence to the agreed timeline

Unlike a fragmented structure (separate architect, project manager, and contractors), the general contractor model centralizes all responsibilities.

For the client, this means:

• One single contract
• One accountable party
• A coherent global vision
• Fewer interfaces, therefore reduced risk

Expertise in Parisian Architecture

For more than 40 years, we have worked on:

• Haussmannian and recent apartments
• Historic buildings
• Contemporary properties
• Atypical spaces and major structural transformations

Renovating an apartment in Paris involves specific constraints: condominium regulations, load-bearing structures, aging networks, and strict electrical, acoustic, and thermal standards.

Our experience enables us to anticipate these parameters from the earliest design phase.

Direction & Accountability

Today led by Grégoire Salinesi-Daumesnil, the firm continues a family legacy built on technical rigor and a structured approach to the profession of general contractor.

With a background in design, interior architecture, and complex project management, he ensures a personal, attentive collaboration for each client, focused on delivering a perfectly executed high-end renovation.

Grégoire Salinesi-Daumesnil personally oversees:

• Project supervision
• Validation of technical decisions
• Architectural coherence
• Strategic site monitoring

This direct involvement guarantees a consistent level of excellence across every high-end apartment renovation in Paris.

Your Project

Are you planning to renovate your property in Paris or elsewhere in France?

As a general contractor, we support you with a comprehensive, structured, and committed approach.

Contact us for an initial feasibility consultation.

 

We offer a comprehensive solution for your interior design and refurbishment projects, by  combining interior architecture, blueprint creation, conducting and monitoring work, and post-project maintenance, to deliver a turnkey service. Salinesi interiors assists you when choosing your property, if you do not already own it. Thanks to our expertise, we are able to help you conduct an audit of your future property and reassure you promptly on your acquisition.

During the first meeting with you at the agency or on the site of the property you wish to refurbish, we study your needs, understand your expectations and asses your tastes in order to provide you with a made-to-measure project, that is customized to fit your needs. We then take the measurements of your property : we are equipped with the latest measurement technology and take 360° pictures in order to not miss a thing.

 

We are committed to sending you the following elements within 48h from the taking the measurements :

- A quote for the “pre-project” study : the study contains 3D visuals of your finished project and technical blueprints which will be used by the workers and craftsmen. The study must be precise so as not to cause any delays in the project.
- A Cost estimates for the work to be done so as to give you a global vision of the budget.

 

As soon as you give us your approbation on the quote for the “pre-project” study, we will start to work on it and imagine different layouts for the restructuring and remodeling of your property from which to choose.

 

This is done in a three step process  :

- We provide you with a selection of varied blueprints in 2D defining possible layouts;
- You select your two favorite layouts and we present them to you in 3D in order to allow you to project yourself better; 
- Lastly, you select the final blueprint, we finetune it, tweak the project and add details to it.

 

Once the choice is made, we provide you with a “pre-project” as well as a final quote for the project.

 

If your project requires it, we can assist you with administrative preparations related to the work, such as :

- Obtaining construction permits
- Obtaining approbation from co-owner’s association
- Having bailiff’s reports made

 

We can also have your furniture removed from the property before the work starts and kept in a storage facility. Once the modelling is done, we also offer interior decoration services ! In addition, we can provide other services such as finding you trustworthy people to clean your apartment, or provide maintenance services. To sum it up, we take care of everything, from preparing the blueprint, to delivering the property entirely refurbished. We coordinate  and manage the work of all of the craftsmen and workers on your project and are your only interlocutor. This way, we can provide professional work, and avoid any stress on your part.

 

You can chose to attend site meetings, or follow the project from a distance, thanks to our weekly immersive reports, which are particularly suited for our expat clients.
