 HD Squared Architects, LLC is an award-winning, women-owned architecture, interiors, and consulting firm based in Downtown Annapolis, Maryland.

 We create spaces that are more than just four walls – they are thoughtful designs that combine creativity, sustainability and practicality.

Founded by Melanie Hartwig-Davis, AIA, NCARB, LEED AP BD+C, our firm is built on her belief that “Everyone thrives in well-designed spaces, and quality architectural design should be available to all in communities that are sustainable and holistic.” Sustainability isn’t an afterthought, it’s the foundation. Whether designing intimate interiors or recreating and expanding to meet future needs, every project reflects our commitment to resilience, adaptability, and long-term flourishing communities.

For over 25 years, Melanie has combined her expertise as an architect with her passion for community impact. She sees beyond square footage and floor plans to the human stories unfolding within each space. Her work springs from a core belief: nurturing environments enhance quality of life and should be accessible to as many people as possible.

We foster deeply collaborative relationships with each client, understanding that their projects are expressions of their dreams. As an NCARB-certified firm licensed in Maryland and the District of Columbia, we bring exceptional expertise and versatile creativity to every endeavor. Our portfolio underscores our dedication to co-creating sustainable, meaningful designs that enrich lives and strengthen community resilience.

At HD Squared Architects, we are passionate about utilizing our talents to improve the lives of others by incorporating resilient design as we transform existing buildings and create new structures.

While this is not always at the forefront of our clients’ expectations, we believe that meeting their project requirements has larger implications and provides unforeseen opportunities. As we strive to exceed our client’s expectations, we strategize how our design choices will have minimal impact on the natural environment and ideally even improve conditions for our ecosystems. It is through this method that resiliency is improved for generations to come.

Each client and project are unique. Budgets and priorities are integral to the project’s success and determined through transparent conversations. Proven processes lead us through collaborative relationships with our clients where active listening enables us to transform shared visions into a built reality.

Create spaces that bring beauty and function into people’s lives; spaces that are healthy and restorative for both people and the planet.
