Our Design Philosophy

We believe in creating environments that support real living. That may be for family time, a sanctuary, or a place for socializing and entertaining. Classic design is timeless, and a family-friendly home can also be high in sophisticated style.

We have a love for light-filled spaces, open floor plans, clean lines, natural materials, unexpected mixes of materials, and the occasional flourish of pattern and color. 

As fellow career-oriented professionals with families we love, we’re passionate about making your life easier — not just during the design and build process, but in the creation of spaces where daily joy is found and lifelong memories are made.

Our Founder + Principal

Rosanna Bassford started Memmo Interiors (formerly Eggshell Home) in 2016. She and her team specialize in architectural interior design, project management, and furnishing and decoration for custom homes and full-home renovations in Silicon Valley.

Rosanna has always been immersed in the design-build world with general contractor parents. Her MBA from the Kellogg School of Management at Northwestern is an asset to clients in project management, investment budgeting, and cross-team collaboration rounded out with her coursework from UC Berkeley Extension’s Interior Design and Architecture program.

Rosanna lives with her husband and two daughters in Silicon Valley and happily shares the neighborhood with her parents and her sister’s family.

“Rosanna was a pleasure to work with and so understanding and patient with me through the whole process, providing guidance, feedback, and answering questions. I am very happy with my home and I get so many compliments from my guests, including that my home looks better than the model home!”

— Michelle, Orange County

Our Design Process

There are hundreds of decisions to be made when designing and building a home, from the way it flows to the materials used and the features that will support your family’s lifestyle. We lead the conceptualization, design, and implementation of your home’s interior, including the layout, aesthetic vision, finish and material selections, project management, and furnishings procurement and installation.


01. DISCOVER

Our discovery phase is essential to building trust and allowing us to become your advocate and guide during this process. We spend time getting to know you, your goals, your design style, and your lifestyle in order to design a home personalized to you and build a solid foundation for success.

02. DESIGN

We collaborate with your architect to develop the floor plans and architectural elements like windows, millwork, and lighting plans. We will also select materials and finishes for the home (flooring, counters, cabinets, etc.) and source furnishings and decor to complete the design.

03. IMPLEMENT

We will track construction progress, oversee ordering and delivery of materials, and represent you on-site for walk-throughs with contractors. We field design-related questions and resolve issues that may arise, serving as liaison between you and your builder. We procure furnishings at this time.

04. FURNISH

Construction is complete. We bring in trades for any decorative work (like wallpaper, window treatments or art installation), schedule furniture deliveries, and bring in all the finishing touches. Now, it’s ready for you and your family to call it home.

“We had never worked with a professional home designer before, so we were a little nervous about the whole process. But from the very beginning, Rosanna had a vision. She was highly organized and focused. She not only helped us transform our new house into a home, one that is comfortable, elegant, and cohesive, but she saved us a lot of time, energy and money.”

— Sarah, Los Altos
