Architectural Design for Largo's Residential and Commercial Growth Corridors
Great architecture balances vision with feasibility. In Largo, that means designing homes and commercial spaces that are beautiful, functional, and compliant with City of Largo Building Division standards. HBDE's architectural design team brings 10+ years of Pinellas County experience and a deep understanding of what works in Largo's neighborhoods, from the Central Park area's walkable infill character to the US 19 corridor's commercial overlay requirements.
Whether you're planning a residential renovation in the Belcher Road corridor, an ADU conversion on a Central Park property, a mixed-use infill project, or a commercial tenant improvement, our architects collaborate closely with you to translate your vision into code-compliant, permit-ready designs. We integrate structural, mechanical, and site planning considerations early, so your design doesn't just look good, it performs and permits smoothly.
Our in-house team works from concept sketches through final construction documents. Flat-fee pricing keeps your budget predictable. We respond to client comments and coordinate with the City of Largo Building Division to ensure timely approvals.

Residential Renovation & Addition Design
Largo's established neighborhoods benefit from thoughtful renovation and addition design. We specialize in expanding homes while respecting setback requirements, maintaining neighborhood character, and optimizing use of sandy soil foundation strategies. Central Park area, Ridgecrest, and East Bay residential projects are areas of focus.
Commercial Design & Tenant Improvements
