And I’ll support you all the way, from A to Z.

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.

Rue Fréville Le Vingt

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

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.
