Design that
fuses form
with function.
Aubyn Architecture LLC is a licensed architecture firm delivering full-service architecture, landscape design and outdoor rooms across Delaware, Pennsylvania and Connecticut.
Every project benefits from three core strengths.
Versatility
From intimate residential renovations to $70M+ healthcare programs, we work across project types, scales and program requirements with equal depth and rigor.
Strategic Thinking
Years of owner's-side project leadership mean we see the full picture — regulatory processes, stakeholder expectations, and design decisions tied to long-term operational and financial goals.
Collaboration
Great buildings are built by great teams. We work seamlessly with engineers, contractors, manufacturers and community stakeholders toward a unified result.

Architect. Landscape Designer. Entrepreneur.
Aubyn Architecture LLC is led by David C. Ainsworth, AIA, NCARB — a registered architect with more than 25 years of experience spanning residential, commercial and healthcare design, including senior owner's-side project management at Yale New Haven Health and Temple University.
Registered in Delaware, Pennsylvania and Connecticut, we deliver full architectural services — from schematic design through construction administration — on every project we take on.
Our work spans sectors because great design principles are universal. Whether it's a 3,200 SF beach residence or a $70M+ inpatient neonatal program, our commitment to quality and client service never wavers.
"Design begins with listening and ends with buildings that endure."
Form, Function,
Fusion.
Our work finds balance and harmony between the natural and built environment — elegance in simplicity, beauty in the subtle. The best architecture doesn't compete with its surroundings; it completes them.
A dedication to efficient resource use and zero-waste design is not a constraint. It is a creative discipline that consistently produces more thoughtful, enduring results.
"Architecture is the sole profession qualified to design and advise — with technical and aesthetic judgment — on the built environment, thereby inspiring the community and its citizens."
Public Health & Safety
Architects are obligated to protect the public interest. That obligation now encompasses sustainability of the global environment and accessibility for all persons — not just code compliance.
Design Excellence
We create functional layouts, energy-efficient construction and visually compelling environments that increase market value while delivering genuine human benefit to occupants and community.
Client Advocacy
Architecture is largely self-regulated. We take that responsibility seriously. Every decision is made in service of your interests, in accordance with the highest professional standards.
Built work and owner-side leadership.
Prior-role projects were delivered by the principal as owner's representative project manager.
Let's build something extraordinary together.
Whether you're planning a new build, a renovation, an outdoor room or a backyard home — we're ready to listen first and design second.
