What Sets Us Apart

At BAAINTERIORS, we are proud to be part of an award-winning architectural design studio. What truly sets us apart is our seamless integration of architecture and interior design—we see the house as one unified space, not separate parts.

We design interiors with a deep understanding of the architectural context. This allows us to create spaces that are not only beautiful but also structurally and spatially cohesive.

Key principles that define our approach:

  • Architecture + Interiors = One Vision
    We design interiors that work in harmony with the architectural form, ensuring consistency in flow, scale, and proportion throughout the home.

  • Joinery and Detailing with Purpose
    Thoughtful joinery and bespoke details are designed to complement the space, align with ceiling heights, and create a sense of symmetry and cohesion.

  • Integration of Services
    We consider the placement and design of all lighting, electrical, and service elements to ensure they support the overall design—not interrupt it.

  • Total Home Understanding
    Our team understands the full architectural picture. That means everything—from wall finishes to furniture layout—is considered within the broader framework of the home’s design language.

  • Collaborative Teamwork
    Our interior designers work closely with our in-house team of architects. Through constant collaboration and brainstorming, we ensure your project benefits from a unified vision—where interiors and architecture work together, not against each other.

  • Avoiding the Common Pitfalls
    Many projects suffer from a lack of coordination between separate architects and interior designers. At BAAINTERIORS, our integrated approach eliminates this risk, delivering a more streamlined process and superior result.

  • An Investment in Quality
    By working with a professional, coordinated team of architects and interior designers, you’re investing in a home that not only looks and feels right but enhances your everyday life.

What People Are Saying

“We engaged Claus to completely redesign our existing 1970's brick home in Northgate; and add a large extension to the side of the house. Claus and his team were so patient and always available throughout the design and now the build. The outcome has greatly surpassed our expectations. The home is timeless, unique and will suit our needs perfectly. We will definitely engage Claus for any future projects and would highly recommend him.”

— Client Lisa Glasgow

“Claus Ejlertsen was instrumental in assuring that our renovations at our home in Clayfield went smoothly, were completed on time and for us were completely stress free. Not only was Claus involved in the design he also sourced out the most competitive builders and managed the entire project. The new renovations were creative, practical and accommodated our requirements. As overseas clients, to us the most important factor of the entire venture was the regular communication we had with Claus, he involved us in every aspect of the building process when required and we looked forward to the weekly photos of the building progress.
We felt at all times that quality and our best interest was Claus’s priority”
