Interior Design for
High-Investment Renovations
& New Construction
*
Our studio with homeowners and builders on high-investment renovations and new construction to ensure design decisions are fully resolved before construction begins — reducing change orders, delays, and costly mistakes.
Our Approach
Construction projects move quickly, and design decisions made too late can be expensive to reverse. SB Interior Design operates as part of the project team during planning and preconstruction, ensuring that interior design intent is fully documented and aligned with construction scope, pricing, and execution.
Our role is to:
Eliminate guesswork for builders and trades
Minimize change orders during construction
Protect the client’s overall investment through early design clarity
This approach allows projects to proceed with confidence, coordination, and accountability.
Recognition
SB Interior Design has been recognized as Best Local Interior Designer by The Morning Call for two consecutive years—an acknowledgment of the firm’s professionalism, client experience, and consistent design outcomes.
Who We Serve
Homeowners planning high-investment renovations or custom homes
Clients who value early decision-making and documentation
Projects involving a builder or construction team
Clients who see design as a critical part of the construction process
Decorating-only services and hourly consulting are not offered.
SB Interior Design specializes in interior design for construction-driven projects, where clarity, coordination, and early decision-making are essential to a successful build.
Our work is focused on high-investment renovations and new construction, partnering with homeowners and builders to resolve interior layouts, finishes, cabinetry, lighting, and details before construction begins. The goal is not decoration after the fact, but design resolution that reduces costly uncertainty during the build process.
Founded in 2018 by Christina Wallitsch, SB Interior Design is built on a foundation of architectural training and interior design expertise. With over 16 years of experience in architecture and interior design, Christina brings a technical, construction-aware perspective to every project.
Her background allows her to bridge the gap between design intent and real-world execution—working closely with builders, architects, and trades to ensure that decisions made on paper translate accurately into the finished home.
SB Interior Design serves clients throughout the Saucon Valley, PA Main Line , PA and Central New Jersey. Our team works with a limited number of projects each year to maintain a high level of involvement and coordination.

Christina was very thorough and listened to my ideas and thoughts and then added her own suggestions to help me with my kitchen/dining room renovation design. I really enjoyed all her insight, experience, and I would highly recommend her to friends and family.
