Sanctuary Design Group, LLC – Stefan Eitnier
Sanctuary Design Group, LLC is a premier, full-service architecture studio dedicated to providing thoughtful architecture and interior design solutions where design meets intentional living.
Based in St. Petersburg, Florida, and serving the greater Tampa Bay market, we specialize in transforming visions into exceptional reality.
Founded on the philosophy that our physical environments profoundly impact our lives, we deliver bespoke residential development, urban design, and commercial architecture tailored to our clients' unique aspirations. Led by Principal Architect Stefan M. Eitnier, AIA, NCARB, our team focuses on crafting refined, timeless structures that beautifully tell a story. Whether it is a luxury custom home or a commercial project, we balance high-end aesthetic elegance with functional, intentional design. At Sanctuary Design Group, we specialize in transforming existing structures into meaningful, high-performing spaces. Our expertise in adaptive reuse and interior architecture allows us to masterfully modernize older buildings while fully preserving their unique architectural integrity.
We take a comprehensive approach to every project, offering thorough feasibility and planning services, site evaluation, and upfront zoning analysis to support confident decision-making right from the start. By pairing concept-driven architecture with detailed physical styling, we ensure that every square foot of an interior environment or exterior elevation functions flawlessly and stands up to the demands of the regional Florida coastal climate. Innovation and modern efficiency are central to our architectural process.
We realize our clients' visions through the strategic implementation of cutting-edge design technologies, including Building Information Modeling (BIM), Virtual Reality (VR), and Augmented Reality (AR). By leveraging these advanced platforms, Sanctuary Design Group, LLC offers enhanced visualization, faster decision-making, improved building efficiency, and significantly reduced errors during construction. This technological integration ensures a smoother transition from early conceptual mood boards to technical 3D architectural rendering and drafting, giving clients complete transparency and confidence before ground is ever broken. Navigating the local building landscape is another key pillar of our studio. We clear the path to construction by providing expert code navigation, securing agency approvals, and compiling permit-ready drawings that mitigate real-world risks on-site. Our comprehensive project documentation translates directly into city-approved plans, smoothing out the often-stressful municipal permitting phase. Once approvals are finalized, we offer dedicated construction administration and on-site oversight. This continuous professional support fosters close coordination with engineering teams, general contractors, and specialized consultants to guarantee that our original design intent is perfectly realized.
Ultimately, Sanctuary Design Group, LLC is committed to sustainable, energy-efficient architecture and innovative problem-solving. We creatively resolve complex design challenges to manage long-term operational costs effectively, maximizing spatial functionality without sacrificing premium luxury aesthetics. From spatial layout optimization and advanced material selections to curated interior decorating, furniture sourcing, and lighting layouts, we manage every single moving part of the design process. We invite discerning homeowners, commercial developers, and local builders within the Tampa Bay region to collaborate with us to create spaces designed with purpose. Let us transform your commercial hub or residential layout into an inspiring architectural sanctuary that stands the test of time.
