Introducing Maison Mousselon

For founder Sophie Mousselon, the idea of “house” goes beyond walls and décor—it represents a welcoming space where friends gather, families grow, and memories form. Maison Mousselon strives to reflect that sense of comfort, anchored by functionality and timeless style. Whether it’s a complete renovation or finishing touch, Sophie aims to optimize each home’s flow, storage, and visual impact using carefully selected materials and thoughtful design details.

She now keeps all of her supplier details in one searchable library, organizes products by category, and builds supply lists for clients without the tedious back-and-forth of scattered files.

When Sophie first tried Programa, she was simply looking for a central product database. It quickly became her everyday design companion. She now keeps all of her supplier details in one searchable library, organizes products by category, and builds supply lists for clients without the tedious back-and-forth of scattered files. Clients can even log into a personalized dashboard to see mood boards and product lists—all in real time. Meanwhile, Sophie manages tasks via Programa’s to-do lists, ensuring no detail slips through the cracks.

Solving Daily Challenges

Maison Mousselon often juggles dozens of project updates: new references, supplier invoices, changing client feedback, and evolving design concepts. By consolidating everything into Programa’s schedules, libraries, and client dashboards, Sophie eliminates the usual risk of misplacing information. It becomes a single source of truth for each project, allowing her to keep track of every product, cost, and conversation in an organized, visually appealing format. That way, Maison Mousselon stays agile—easily sharing real-time updates with clients and ensuring every home reflects its owners’ personality and needs.

Sophie MousselonFounder

It all started with this word, house.

A word that reminds me of a place of anchor for a family, a place to come together, celebrate strong moments, welcome friends.

And as a silent witness, this place, which we wish to reflect its image. Sometimes bold, sometimes wiser, always timeless, above all functional.

A soothing place, an energizing place, a rejuvenating place.

So it is with joy that I present to you Maison Mousselon, a house at the service of yours. With passion and attention to detail, my mission is to reveal the beauty of your living space.

Founded by Sophie Mousselon, the agency is dedicated to complete renovations of apartments or houses and also offers decoration services.

Streamline circulation, create views, provide contrast, design tailor-made storage to optimize space, select durable materials, play with textures. Endless possibilities for creating beauty.

Programa has become essential to the functioning of my agency.

Sophie MousselonFounder

I use Programa every day. I discovered the solution because I was looking for a functional database to reference all the products that we place on each project but also to be able to integrate the favorite references identified during our research and easily accessible in a single location using category filters.

I then discovered all the services offered by Programa and there are many more. I was able to centralize all my supplier data, create supply lists for my clients, give them access to the dashboard with the mood board and product lists or even create my to do's per project.

Programa has become essential to the functioning of my agency.

In this in-depth exploration of Kim Kneipp Studio, we uncover the story behind a thriving interior design practice rooted in a personal transformation from fashion to interiors. Founded by Kim Kneipp, a former fashion designer who became disillusioned with the industry's wastefulness, the studio is driven by a commitment to sustainability and creating spaces that are both functional and deeply personal. Kim’s early journey involved teaching clients to curate and alter their wardrobes sustainably, which eventually led her to rearrange and style homes. Her hands-on training, combined with extensive collaboration with architects and builders, evolved into a fully-fledged interior design studio.

The core mission of Kim Kneipp Studio revolves around curiosity, resilience, and professional problem-solving, all anchored in sustainable design practices. The studio culture is described as a tightly-knit, creative environment where collaboration and joy flourish. Set in a vibrant Brunswick East warehouse, the studio operates among a community of creative professionals, fostering a spirit of collaboration both within and outside the studio walls.

Project selection at Kim Kneipp Studio is a careful process, focusing on clients whose values align with the studio’s ethos. The team takes on diverse projects, including commercial, residential, and wellness spaces, while balancing timelines and budgets. Collaboration is at the heart of the studio's success, with a network of artisans and tradespeople who work closely with Kim’s team to bring projects to life. Each project is infused with empathy and a playful, irreverent touch, creating spaces that are not only functional but also rich in narrative.

A hallmark of the studio's approach is the integration of vintage materials and bespoke joinery, which adds character and depth to every design. Kim’s commitment to using natural materials that age beautifully aligns with her belief in sustainability. The studio sees sustainability not as a trend but as a core principle that informs all design choices.

Technology plays a supportive role in the studio's operations, with tools like Programa, SketchUp, and AutoCAD enhancing communication and project management. Although the team leans towards a hands-on, tactile approach to design, they recognize the value that these programs bring in terms of efficiency, especially in client communications and task scheduling.

Overall, Kim Kneipp Studio is guided by a philosophy that marries creativity with functionality, crafting spaces that reflect the unique personalities of their clients while embracing the unpredictability of design challenges. Through their use of Programa, the team has streamlined specification processes, enhanced client communication, and built stronger, more transparent relationships with their clients.
