At Building Products Group in St. Louis, MO, we believe that true craftsmanship lies in the details. Architectural features not only define the appearance of a structure but also influence its durability, efficiency, and overall identity. Our architectural detailing services and materials bring precision, artistry, and performance together—helping architects, builders, and designers achieve results that are as functional as they are beautiful.

As specialists in energy-efficient masonry and wall systems, we understand that every joint, moulding, and finish plays a role in long-term performance. Proper detailing ensures superior moisture protection, sound control, and insulation, while maintaining aesthetic integrity. Building Products Group supplies and supports products that help architects refine the building envelope—from Autoclaved Aerated Concrete (AAC) mouldings and trims to stone accents and dimensional components that elevate design quality.

Limestone, Cast Stone, and Custom Trims

We provide Indiana limestone, cast stone, and architectural trim elements that add elegance and structural precision to both modern and traditional projects. Our stone detailing capabilities include sills, coping, cornices, surrounds, and decorative mouldings—all produced with the highest level of accuracy. These elements can be used to frame windows, define entries, or accentuate facades, adding texture and timeless appeal to any building.

AAC Mouldings and Finishing Components

Through our partnerships with New Castle and Celcrete, we offer a full range of AAC architectural mouldings, trims, and finish components designed to complement energy-efficient wall systems. These lightweight, durable pieces can be shaped into intricate profiles while maintaining excellent weather resistance and insulation performance. They are ideal for projects requiring both design flexibility and environmental responsibility.

Integration with Metal and Engraved Elements

Architectural detailing often involves more than stone and concrete—it’s also about combining textures and materials for visual harmony. Our team can integrate cast bronze or aluminum plaques, engraved stone markers, or dimensional lettering into architectural features for a cohesive, polished appearance. These details create opportunities for branding, identification, and artistic expression that enhance the overall design narrative.

Precision, Performance, and Aesthetic Value

Every component supplied or fabricated by Building Products Group is engineered to meet the highest standards of precision and quality. We coordinate closely with design professionals to ensure proper scale, proportion, and material compatibility. Whether the goal is to match historical architecture or introduce contemporary lines, our detailing solutions help maintain design intent while optimizing performance.

Our products are low in embodied energy, highly resistant to fire, moisture, and pests, and built for long-term resilience. This combination of beauty and function makes them ideal for projects that demand durability without compromise.

Collaborative Design Support

We understand that architectural detailing requires careful coordination between designers, fabricators, and installers. Our experienced staff offers consultation and technical assistance throughout the design and construction process, helping teams choose the right profiles, finishes, and attachment methods. From concept to completion, we ensure that every element integrates seamlessly into the overall structure.
