About our architectural arch & keystone systems

We deliver the monumental look of solid stone in a precision-engineered system that assembles flawlessly on site.

The anatomy of a perfect first impression

Monumental, elegant, and engineered for perfection—our architectural arches are crafted from high-density, lightweight materials to replicate a solid, monolithic stone archway without the engineering nightmare. Perfect for creating powerful first impressions on commercial properties and luxury homes, these systems add a definitive statement of quality and design authority.

Each decorative arch system consists of precision-made components:

  • The Arch: The primary structural form, engineered for perfect curves and crisp lines. Available in any profile you can design, from a subtle decorative wall arch to a soaring entryway.
  • The Keystone: The crown jewel of the arch. Our decorative keystones provide the critical finishing touch, available in classic, modern, or completely custom designs.
  • Supporting Trim & Moldings: Optional elements that integrate the arch seamlessly with the surrounding facade for a fully resolved architectural feature.

Get a modular system that installs with absolute precision, every time.

The science behind flawless form & enduring strength

Our architectural arch systems are built from an advanced composite of materials engineered for a century of performance. At the core is a structural, high-density Expanded Polystyrene (EPS) foam, precision-cut with CNC technology to achieve any geometry your design demands.

This core is then fully encapsulated in our signature polyurea hard coat. This isn’t just a coating; it’s armor. The spray-applied elastomer creates a seamless, waterproof, and impact-resistant shell, transforming the lightweight foam into a monolithic structure with incredible resilience.

The final layer is an integrated, architectural-grade finish that provides the authentic texture of limestone, precast concrete, or any other specified material. This advanced construction makes our decorative arches robust, beautiful, and virtually maintenance-free for 80-100 years.

Before and after:
a strategic transformation

decorative doorway arches
Before:

The Challenge: A new commercial building had a functional but forgettable entrance. The flat, generic facade failed to project the high-end, established image the tenants desired, blending in with surrounding properties and lacking any architectural distinction. The developer needed a high-impact upgrade without the massive cost and structural rework of adding a precast concrete arch.

After:

The Solution: We engineered, fabricated, and delivered a complete decorative arch and keystone system. The lightweight, pre-finished components were installed by a small crew in a single day, causing zero disruption. The design was tailored to complement the building’s existing lines, instantly adding a sense of grandeur and permanence.

The ROI: The property was transformed from a generic box into an architectural landmark. This powerful new entryway dramatically increased its curb appeal and perceived value, directly contributing to faster lease-ups at premium rates. This wasn’t just a cosmetic addition; it was a strategic investment that paid for itself.

Arches and Keystones

The first impression of a facade is like a firm handshake at an important meeting — it sets the tone before a single word is spoken. Decorative arches, arches for doorways, decorative doorway arches, decorative wall arches, decorative garden arches, arches for homes, decorative exterior keystones, and decorative keystones are the architectural details that quietly shape that first impression. For 25 years, we’ve been helping architects, builders, and designers achieve that balance between function and emotion — creating buildings that look more expensive than they cost, stand out without screaming, and deliver results without delays or risks.

We know what matters on real projects. You need elements that look like carved stone or solid timber but don’t require cranes to install. You want components that stand up to rain, heat, and salt air. You want details that can be customized to match your design language — and you want all of this delivered on time, without disrupting schedules. That’s where our experience and solutions come in, from exterior corbels and exterior gable corbels to arches, arched doorways, and keystones made for real-world construction.

decorative arches for doorways 2

What it is and why it matters

 

Arches and keystones have been around for centuries because they do more than hold up masonry — they hold the whole composition together. A door header or a keystone locks the shape in place, while exterior corbels and brackets visually support overhangs, balconies, and rooflines. Together, these elements bring order and rhythm to a facade, framing doors and windows in a way that makes architecture both functional and memorable.

decorative keystones

History and development: From victorian lace to pragmatic modern

 

The story of facade decoration is a story of changing tastes. In the Victorian era, buildings were meant to impress — heavy ornament, floral carvings, and exterior Victorian corbels that shouted wealth and confidence. By the early 20th century, the mood shifted toward simplicity and honesty. Craftsman exterior corbels reflected strength and integrity, with designs that felt handmade and built to last.

Later, the American farmhouse style introduced warmth and nostalgia. Farmhouse exterior corbels under gables and arches over doors gave buildings a welcoming, lived-in character that still resonates today. And now, minimalism is king: clean lines, pared-down silhouettes, and thoughtful details do the talking. We’ve evolved with every shift, refining shapes, materials, and finishes to capture the essence of each era while meeting modern performance standards.

Materials and technology: Strength without excess weight

We use engineered foam with a multi-layer mineral coating — light, durable, resistant to moisture and UV, and capable of mimicking wood or stone so convincingly that most people can’t tell the difference.

CNC milling and 3D modeling ensure every curve and edge is replicated perfectly, even on large-scale projects. For example, a boutique hotel in Sarasota needed arches to align with window mullions across 200 feet — the result was seamless.

Custom color matching lets us replicate the precise shade of your siding or paint sample. During a courthouse restoration in Georgia, we matched a 120-year-old sandstone color so accurately that even the preservation board couldn’t tell which parts were new.

Samples and 3D mockups let you preview the final look before production. One coastal resort near Clearwater adjusted the size of exterior soffit corbels and door headers after reviewing a mockup — saving weeks of redesign time.

Logistics and lead times

 

We deliver labeled, installation-ready components when you need them. No delays, no storage headaches, and often projects finish ahead of schedule.

Types and examples of use

 

First, the big picture

We design complete systems: arches with keystones, exterior corbels on the house for balance, and exterior decorative brackets for rhythm. Every facade has its own story — sometimes you need bold large exterior corbels visible from the street, sometimes subtle architectural exterior corbels that reveal themselves up close.

Gables and eaves

Exterior gable corbels define rooflines, anchor the visual axis, and make structures feel grounded. Exterior soffit corbels set rhythm and balance.

In Panama City, a rural school needed presence — something that gave it weight without making it feel like a museum. After adding corbels and framing the arched doorways, the building felt “steadier,” like a quiet but confident voice among its surroundings.

Entrances and portals

Exterior corbels and brackets shape the first impression at entry points. Add exterior corner brackets, and even a simple door feels welcoming.

A manor near Savannah, used for weddings, wanted a sense of tradition. We designed a tall keystone arch and decorative exterior brackets with a grapevine motif — guests now line up to take photos under it.

Handrails, stairs, terraces

On a waterfront walkway in St. Pete Beach, we used exterior architectural brackets with built-in LED pockets — soft, inviting light at night, clean lines by day.

Contemporary style that speaks through details

 

Modern projects are all about clean lines, bold shapes, and the kind of elegance that doesn’t need to shout to be noticed. That’s exactly what modern exterior corbels bring to the table — they frame the building with crisp geometry and cast those long, dramatic shadows that change with the light throughout the day.

Think of them as the perfect finishing touch on a tailored suit: subtle at first glance, but impossible not to appreciate once you notice how much they elevate the whole look. They don’t fight for attention — instead, they quietly draw your eye to the architecture itself, making the facade feel refined, confident, and effortlessly put together.

decorative wall arches

Timeless reinterpretation

From exterior Victorian corbels to exterior Craftsman corbels, we don’t just copy — we reinterpret details with modern performance in mind.

A parish in Jacksonville had a tired west portal. We rebuilt it with architectural brackets and corbels inspired by Gothic arches, finished with a tactile stone-like texture. Parishioners said the building suddenly felt “deeper,” and the rector joked the bell wasn’t just heard anymore — it was seen.

Assortment highlights

  • Extra large exterior corbels for bold, visible structure.
  • Exterior gable corbels and exterior soffit corbels for clean rooflines.
  • Decorative exterior brackets and arches for entrances.
  • Victorian, craftsman, and farmhouse exterior corbels for classic styles.
  • Modern exterior corbels for sleek, minimal builds.

Spaces that welcome: Retail, restaurants, and beyond

We often pair exterior brackets and corbels with brand colors to create complete facade kits. For a Miami coffee chain, we designed compact sets for narrow streets, bold large exterior corbels for flagship stores, and exterior decorative brackets engraved with the logo — customers now photograph them before even going inside. In one flagship location, the team even styled the interior with a curved sofa to echo the exterior arches — a subtle but powerful branding detail.

Where they’re used

Project TypeApplications and Impact
Urban homesExterior house corbels and doorway headers add scale and proportion.
Commercial buildingsModern exterior corbels and arches create rhythm and visual clarity.
Hospitality projectsExterior roof corbels and exterior corner brackets build identity and emphasize windows.
Cultural venuesArches and corbels on house exterior guide visitors naturally.
Unique sitesYacht clubs, pavilions, and historic estates where exterior architectural brackets define identity. At a restored estate near Savannah, custom brackets inspired by original woodwork were aligned with existing arches and doorway headers to blend history with modern precision.

How we became a niche market leader — and why companies like amazon and red bull choose us
