Architecture

Interior architecture is where form meets function. It’s the thoughtful design of spaces that start from within, blending structure, flow, and function to support how you live. By understanding your daily rhythms, we create purposeful, personal environments shaped by smart planning and refined detail to ensure every element curated to fit your life beautifully.

Design

Interior design brings spaces to life through carefully chosen furnishings, lighting, and materials that enhance the architectural intent. It’s about crafting atmosphere and texture—layering warmth, light, and tactile details to create environments that feel both inviting and intentional. Every surface, fabric, and fixture is selected to enrich the space and reflect your personal style.

Ethos

AUTHENTIC DESIGN. REAL RELATIONSHIPS. GREAT PROJECTS.

Our studio was founded on a shared belief that great design begins with authenticity in both the spaces we create and the relationships we build.

At Authentus, we offer thoughtful and refined interior design, built on collaboration, transparency and trust. We believe the best results come from honest conversations and a genuinely human approach. As co-directors, we work on every project together, bringing our combined experience and shared passion to each stage of the process. That means you get the benefit of both of us – two perspectives, one cohesive vision, and a strong commitment to delivering exceptional design.

Whether you’re building your dream home or refining a single space, we’ll give your project our full attention. We believe good design should be considered and beautifully resolved, no matter the size or scope of the brief.

MEET THE

Founders

Andrea Martinez

With formal qualifications in both Interior Design and Marketing, I have worked with some of Perth’s most awarded builders and architects on luxury residential homes. Organised, process-driven and collaborative by nature, I thrive on bringing clarity to complex, custom homes with multi-million-dollar budgets.
 
I’m particularly skilled in cabinetry design, joinery detailing, and technical Revit documentation, with a deep understanding of materials, finishes, and sourcing luxury European furnishings.
 
Given my experience living and working abroad, I bring a unique blend of creativity and technical precision to every project. Known for being warm, honest and detail-focused, I design interiors that are elegant, liveable, and curated to each client’s lifestyle.

Emma Austen

Creative yet pragmatic, I specialise in designing refined, functional interiors that are as liveable as they are beautiful. My background in Interior Architecture and extensive experience in high-end residential projects inform a thoughtful, detail-driven approach.
 
I’m highly skilled in design software and documentation, ensuring clear communication from concept through to construction. Calm, honest and action-focused, I thrive on solving complex problems, staying ahead of the process, and working collaboratively with clients, builders and trades.
 
Whether crafting layered interior schemes or resolving technical queries, I deliver interiors that exceed expectations and enhance how clients live in their homes.

If you’re planning a residential project and would like to connect, we’d love to hear from you.
