Accessory Structure Design: Elevating Cabanas, Pool Houses, and Detached Garages

For many homeowners, the term accessory structure once brought to mind something purely functional—a simple detached garage, a modest pool house, or a small garden shed. Today, that definition has evolved dramatically. Accessory buildings are no longer secondary afterthoughts; they are intentional, highly designed extensions of the home that play a vital role in how a property is experienced, used, and enjoyed.

At David Small Designs, we approach accessory structure design with the same level of intention, creativity, and precision as the main residence.

The Evolution of the Modern Accessory Structure

Modern accessory structures have undergone a significant transformation. What were once utilitarian buildings are now fully realized architectural elements designed to support modern lifestyles—often incorporating sophisticated entertaining areas, wellness spaces, or even independent living quarters.

Contemporary cabanas often include outdoor kitchens, covered lounge areas, fireplaces, and washrooms, creating seamless indoor-outdoor living spaces. Detached garages are frequently designed with living space above, accommodating guest suites, home offices, studios, or private retreats. Pool houses and garden pavilions now feature refined materials, generous glazing, and thoughtful layouts that rival the design quality of the primary home.

This evolution reflects how homeowners live today. Properties are expected to support entertaining, working from home, wellness, and multi-generational living—making accessory structures an essential part of the overall design strategy rather than an afterthought.

Why Accessory Structures Should Be Designed Early

One of the most important considerations in accessory structure design is timing. Because these buildings are permanent features you’ll see and interact with every day, they must feel intentional—not added on later as an afterthought. They should be integrated early in the design process.

Incorporating custom accessory structures early in the design process allows for a cohesive vision across the entire property. Rooflines, proportions, materials, and detailing can be carefully coordinated with the main home, ensuring that each structure feels like part of a unified architectural language. When done well, accessory buildings don’t compete with the primary residence—they complement and enhance it. They become architectural features that can be enjoyed from both inside and outside the home, without disrupting flow, scale, or visual harmony.

From a site-planning perspective, early integration also improves how the property functions. Thoughtful placement of cabanas, garages, and secondary living spaces helps define outdoor rooms, enhance sightlines, and create natural circulation between buildings. The result is a property that feels balanced, intentional, and effortless to experience.

Creating Architectural Cohesion Across the Property

Cohesion is key to timeless design. Accessory structures should complement the architectural language of the main home—whether modern, transitional, or traditional—while maintaining their own sense of identity.

When materials, scale, and detailing are consistent, accessory buildings enhance rather than compete with the primary residence. This cohesive approach not only elevates the visual appeal of the property but also ensures long-term relevance, durability, and value.

Well-designed accessory structures contribute to a home’s overall character, making the entire site feel complete and thoughtfully curated.

Designing Beyond the Main Residence

Accessory structures are no longer supporting elements—they are an essential part of how a home is lived in and enjoyed. From elaborate cabanas designed for entertaining to detached garages with living space, these buildings play a critical role in modern custom home design.

At David Small Designs, we believe every structure on your property deserves careful consideration. By designing accessory buildings in harmony with the main home, we create cohesive environments that enhance lifestyle, functionality, and architectural integrity.
