Founded by Mauricio Diaz and Holly Maxwell, Maxwell Diaz Architects is a Sydney based studio creating spaces that respond thoughtfully to people and place.

Mauricio and Holly combine their expertise in architecture, interior design and project management to ensure every project is carefully considered.

We work closely with clients to deliver spaces that are practical and beautiful, guided by a commitment to integrity, respect and thoughtful design.

We believe architecture and interiors should be true, good and beautiful.

True in their response to people, place and purpose.
Good in the way they serve daily life with clarity, durability and care.
Beautiful in proportion, light and material.

This understanding is grounded in the classical tradition that sees truth, goodness and beauty as inseparable. We believe the built environment is not merely functional or aesthetic, it participates in shaping human dignity and flourishing.

Truth in architecture requires honesty, in structure, in material, and in response to site and climate. We avoid novelty for its own sake, seeking instead coherence and integrity.

Goodness is expressed through spaces that serve people well over time. Careful planning, thoughtful detailing and disciplined delivery are not secondary to design, they are moral commitments.

Beauty arises from harmony, proportion, light and material working together in quiet order. It is not excess or spectacle, but something that feels settled, enduring and deeply human.

Founded by Mauricio Diaz and Holly Maxwell, our Sydney-based studio integrates architecture, interiors and project management into a unified practice. We approach each project with attentiveness and respect, listening carefully so that every outcome is both practical and meaningful.

We design with restraint, seeking permanence over trend and depth over display, believing that well-ordered spaces contribute, in their own way, to the common good.
