At RIOS Architecture, we focus on creating homes and spaces that feel rooted in their specific place. The three neighboring Gulf barrier island communities of St. Pete Beach, Treasure Island, and Madeira Beach each carry their own rhythm and practical realities. Homeowners and property owners here often seek an architect who understands not only aesthetics but also the very real demands of building or renovating along this stretch of Florida’s Gulf Coast.
These towns sit on a narrow chain of barrier islands. They share similar exposure to salt air, prevailing winds, and the potential for storm surge and flooding that comes with Gulf-front living. At the same time, each maintains a distinct personality that thoughtful design can honor rather than override. Our work across the broader St. Petersburg area often informs how we approach these neighboring barrier islands.
St. Pete Beach blends a welcoming residential scale with areas that draw visitors, particularly around the southern end near Pass-a-Grille, where historic charm and a quieter beach-town atmosphere remain strong. Properties here often balance privacy with proximity to the water and local amenities.
Treasure Island tends toward a more residential, family-oriented feel with straightforward access to the beach and a community rhythm that many longtime residents value. Vertical or elevated designs frequently make sense on narrower lots to capture views while meeting practical requirements.
Madeira Beach offers its own energy, especially near John’s Pass, where the waterfront activity and local character create opportunities for designs that connect indoor spaces with the lively coastal setting. Across all three communities, successful projects tend to respect existing neighborhood patterns while incorporating modern performance.
If you are considering a new build, addition, or renovation in any of these locations, the right architectural partner can help navigate both the creative and the technical sides from the start.
Properties along this stretch of the Gulf frequently sit in Special Flood Hazard Areas. According to Pinellas County, everyone in the county lives in some type of flood zone, and many barrier island locations fall into high-risk categories (Zones A, AE, V, or VE) that carry a greater than 1% annual chance of flooding.
Pinellas County requires that new construction or substantially improved buildings in floodplains be elevated at least one foot above the Base Flood Elevation. This freeboard provides an important margin of safety. In velocity zones and Coastal A zones, wave action adds further considerations for foundation design, breakaway elements below the elevated structure, and overall structural detailing.
The Florida Building Code includes specific coastal construction provisions that apply in Pinellas County. These address wind loads, corrosion resistance from salt air, and the need for durable materials and connections that perform under repeated coastal exposure. Open foundation systems (piles or columns) are often preferred or required in the most exposed areas to allow floodwater and waves to pass beneath the structure with minimal resistance.
These requirements are not simply regulatory hurdles. They directly influence how a home feels to live in, how it ages, and how well it protects what matters most to the people who call it home. An architect familiar with these conditions can integrate the necessary performance features without sacrificing the light, views, and indoor-outdoor connections that draw people to these beaches in the first place.
If your property is in one of these communities and you are beginning to explore options, we encourage you to reach out to us at (813) 591-0159 early in the process. Early conversations often uncover opportunities to align design goals with the specific conditions of the site.
We bring a practical, collaborative mindset to every project. Our work begins with listening carefully to how you want to live in the space and what matters most about the location. From there, we examine the site’s specific constraints and opportunities, including flood zone classification, elevation requirements, prevailing wind exposure, and neighborhood context.
Design decisions around foundation type, structural systems, material selection, and interior layout all flow from that combined understanding. We pay close attention to how the home will interact with its surroundings - capturing breezes and views while managing solar gain and providing durable protection against the coastal environment.
One example of our recent work in the area is the Dolphin Dr Residence on Treasure Island. This three-story modern coastal home spans nearly 5,600 square feet with four bedrooms and four bathrooms. Its vertical design maximizes the benefits of the site while delivering the elevated, resilient construction appropriate for its location. This type of elevated, view-focused design aligns with the resilient coastal strategies we apply across many Pinellas County projects.
We approach every project with the same attention to detail, whether the scope involves new construction, a sensitive renovation, or an addition that must feel like it has always belonged.
Every project moves through a clear sequence that keeps you informed and involved:
Throughout the process, we keep the lines of communication open. Many clients tell us they appreciate having a single point of contact who understands both the creative and the technical sides of coastal work.
For projects that involve additions or expansions in coastal settings, our home addition expertise provides further insight.

What Makes an Architect Experienced in St. Pete Beach, Treasure Island, and Madeira Beach Different from a General Practitioner? Local experience matters because these barrier island communities have specific flood zone realities, coastal construction requirements under the Florida Building Code, and neighborhood patterns that influence what designs work well. An architect familiar with Pinellas County processes and Gulf Coast conditions can anticipate challenges and integrate resilient features more seamlessly into the overall design.
Do Homes in These Areas Need to Be Elevated, and Why? Many properties fall within Special Flood Hazard Areas. Pinellas County requires new or substantially improved buildings to be constructed at least one foot above the Base Flood Elevation. Elevation, combined with appropriate foundation design, helps manage flood risk and meets insurance and lending requirements in high-risk zones.
How Does Hurricane Resilience Factor into Design for These Gulf Communities? Resilience begins with code-compliant structural detailing, impact-rated openings where required, corrosion-resistant materials, and foundation systems that perform under wind and water loads. Thoughtful design can exceed minimum requirements in ways that improve long-term durability and peace of mind without compromising the open, light-filled character most people want in a beach home.
Can You Work Within an Existing Neighborhood’s Character While Meeting Modern Performance Standards? Yes. We study the specific block and surrounding homes to understand scale, materials, and rhythms. The goal is a design that feels appropriate to its setting while delivering the resilience, energy performance, and livability you expect from a contemporary home.
What Should I Expect When Starting a Conversation About a Project in One of These Communities? We begin by listening. Early discussions usually cover your goals for the property, timeline, and any known site constraints. From there, we can outline next steps, including site analysis and a preliminary conversation about feasibility. There is no obligation to move forward until you feel ready.
How Long Does the Architectural Process Typically Take for a Coastal Home in This Area? Timelines vary with project scope and complexity. A custom new home or significant renovation generally involves several months of design and documentation before construction begins. We provide a clearer picture once we understand the specific scope and any unique site factors.
These three neighboring Gulf communities reward designs that are both beautiful and genuinely suited to coastal living. Whether you are planning a new residence, a thoughtful renovation, or an addition that extends how you use your property, the right architectural partner can make the process clearer and the outcome stronger.
At RIOS Architecture, we combine careful listening with deep experience in Pinellas County coastal conditions. We bring the same coastal focus to complementary work in nearby Clearwater beach communities, and we would be glad to discuss your goals and explore how we might help bring your vision to life on St. Pete Beach, Treasure Island, or Madeira Beach.
