More About Full Service Interior Design

Antonia Mahon, Founder, Blue Sparks Paris

Originally from Ireland, I moved to Paris in 1999 and became Parisienne. (I’m a dual Irish-French national and fully bilingual in English and French. Read more about me here.)

I know how challenging it can be to find, buy, design, and renovate apartments in Paris—I’ve been doing so since 2004, when I bought my first trois pièces (three-room apartment). It was quite a steep learning curve, I can tell you!

Since then, I’ve helped clients bring their Parisian dream homes to life, so I know exactly what to do, how, and when. Let me help you too, so that your experience is filled with joy, not stress!

Avenue Henri Martin

Antonia has a magic wand and makes the impossible, possible! She really listens at the beginning of the process and makes sure she understands the wishes and personality of her client. She is very creative, not only for the design of the apartment, but also in finding solutions to any problems that arise.

Cité Vaneau

We moved to Paris for an expat assignment and rented a furnished apartment, but the style wasn’t ours. We had a budget in mind to make our Parisian home feel like home, even for a short time. Antonia made it come alive, helped us leave our “beige” comfort zone, and brought French lifestyle to our apartment. We’ll end up selling some of the furniture at the end of our assignment, but will take a lot of the decor back to the US so our permanent home can be inspired by Paris and by Antonia.

As I didn’t have time to be involved, I delegated fully to Antonia who looked after everything, even in a complex and stressful context. I’m delighted with the result which is all that I had imagined and more!

Let’s Work Together

Imagine arriving in Paris to visit a shortlist of properties that truly meet your expectations. Understanding the “pros and cons” of each, and the investment necessary to make it feel like home. Having someone who speaks English by your side through the entire buying process, asking relevant questions on your behalf, and translating the answers and their impacts specifically for you. And then, having that same person already understand your vision and needs, ready to design, remodel, and furnish your new home so that you can simply arrive and unpack.

Whether you’re looking for support with finding and buying, or just for the interior design, I’m here at Blue Sparks to make that vision a reality.

Tips — Practical Guides to Buying, Renovating, and Designing in Paris

Rue Gallieni, Boulogne-Bilancourt

I contacted Antonia because I wanted to renovate a studio apartment and use it as both an office and an extra bedroom. Initially, Antonia took the time to understand my style in order to adapt the decor. She suggested plans and furniture. Once the decision was made, she was fully in charge of supervising the construction with the builder. Everything went fast and smooth and the work had been done on time. I’m very happy to say that I really love that space that’s both comfortable and functional. I warmly recommend her.

Rue Saint Honoré, Paris I

We were pleased to find Antonia and to have her help with the refurbishment of our pied-à-terre in Paris. Antonia took the time to understand our lifestyle and design interests and coordinated all aspects of the project from working with our contractor to selecting paint and furnishings to handling delivery and setup. Having a professional like Antonia in Paris, fluent in French and well versed in the details of the home improvement market, made creating our home-away-from-home simple and virtually stress-free. We are very pleased with the outcome and recommend Antonia highly.

Rue de la Tour, Paris XVI

I feel very lucky to have found Antonia and Blue Sparks Design. I needed some furniture recovered soon after we arrived in Paris, and knew I didn’t have the time or the French fluency to find an upholsterer. Antonia came to the apartment shortly after we unpacked for what I thought was just a “meet & greet,” but she rolled up her sleeves and we rearranged furniture, accessories & art. She made it look so much better than I could have done alone! Antonia made wonderful suggestions for additional items, getting estimates and sourcing furniture. In addition, she met me at the upholsterer’s shop and was very patient as she helped me pick gorgeous fabric. I highly recommend Antonia to make your home beautiful.

Cynthia S., Relocated from the United States

Rue du Regard, Paris VI

We just bought small apartment in Paris that needed updating. We weren’t even sure we needed an interior designer considering the size of our apartment. But we are so glad we did hire her. Don’t think, “who am I to use an interior designer?. They are only for fancy people”. Well, Antonia is one of the most nicest, down to earth person we have ever met. We felt comfortable with her at our first meeting. She listens and helps create a cohesive plan based on your style. Yet she also has ideas and suggestions that you might not even thought of to make your vision even better! Equally as important is she has contractors that she knows and has worked with to make your vision a reality. There is nothing more important than trust, and I can’t imagine myself as a non-French speaker to find a contractor, let alone if they are good or even qualified. Your new home is an investment. You can do it yourself and it might not look so good, or you can hire Antonia.

Ferrovial Offices, Versailles

We used Antonia’s services for the refurbishment of our 300 m2 offices in Versailles since the space needed a complete new atmosphere. Antonia took care of making the proposal, coordinating the works with the different contractors, making the orders for the furniture and organising the hand-over. I can only have good words for her diligence, professionalism and attention to detail. The result is excellent and our team is extremely happy in this new luminous and modern space. Thank you Antonia.

Cité Vaneau, Paris VII

We recently moved to Paris for an expat assignment and rented a furnished apartment, but the style wasn’t ours. We had a budget in mind to make our Parisian home feel like home, even for a short time. Antonia made it come alive, helped us leave our “beige” comfort zone, and brought French lifestyle to our apartment. We’ll end up selling some of the furniture at the end of our assignment, but will take a lot of the decor back to the US so our permanent home can be inspired by Paris and by Antonia.

Rue Gay Lussac, Paris V

I had a wonderful experience working with Antonia and her team at Blue Sparks. I will be forever grateful for finding her. The apartment, besides the moldings and traditional details, was a blank slate. She spent a significant amount of time talking with me and getting information about my design preferences and how we would utilize the apartment. She coordinated all the details from needed repairs and updates, restoration, furniture purchases, and craftspersons for the draperies, upholstery, and a beautiful custom-made stained glass window. She sent several drafts of her ideas and updated the status regularly. She listened and adjusted for my preferences. She accommodated my wish for a more traditional style but artfully incorporated some contemporary touches that I love. She kept the tight timeline we requested and she was only delayed by furniture deliveries, that could not be helped. For our convenience, she arranged temporary items for us while we waited for our final deliveries. She was detail oriented, prompt, extremely organized, and really just a lovely person to work with. Every person who has walked into our apartment, or even just seen photos has been stunned by how beautifully it came together. I highly recommend Antonia and her Blue Sparks team.
