What Is an Oriel Style Window?

An oriel window is a form of bay style window that projects outward from the main wall of a property without extending to the ground.
Unlike traditional bay windows, oriel windows often appear suspended or floating, creating a more contemporary and architectural appearance.
Historically, oriel windows were commonly used in period buildings and heritage properties, but modern designs now use slimline aluminium frames and structural glazing systems to create sleek contemporary installations.
An oriel window is designed to brighten darker rooms by extending outward from the house, creating additional natural light and improving outward views.
This style of window creates an opportunity to frame a specific garden view while making the internal space feel larger and more open. Many homeowners also use the extended area to create a window seat or decorative feature.

Why Is It Called an Oriel Window?

The word “oriel” originates from medieval architecture and historically referred to an upper-floor projecting window supported by brackets or corbels.
Traditional oriel windows were commonly found in castles, manor houses, and historic buildings where they created additional light, visibility, and decorative architectural detail.

Today, the term is still used to describe projecting windows that extend outward from the building structure while creating a dramatic architectural appearance.

Oriel Windows vs Bay Windows

Many homeowners compare oriel windows vs bay windows when planning home improvements or extensions. Although they share similarities, there are several important differences between the two styles.
Modern Oriel Windows Cost

Bay Window

A traditional bay window usually extends from the ground level and is supported directly from below. Bay windows often include multiple window panels and create extra floor space internally.

Oriel Window

An oriel window projects outward from the wall but appears more suspended or floating. Modern oriels are usually supported using concealed structural steel or timber supports.

Key Differences Between Bay Windows and Oriel Windows

Feature Bay Window Oriel Window
Support Structure Ground-supported Cantilevered or bracket-supported
Appearance Traditional Modern & architectural
Design Style Classic Contemporary
Structural Complexity Moderate Higher
Cost Lower Higher
Floating Effect No Yes

Modern homeowners often choose bay window oriel designs because they combine the spacious appearance of bay windows with the sleek floating look of contemporary architecture.

How Much Do Oriel Windows Cost in the UK?

Oriel windows cost more than standard in-wall windows because of their structural complexity, bespoke manufacturing requirements, and specialist installation process.

The total price depends on:
  • Window size
  • Frame material
  • Structural requirements
  • Glass specification
  • Installation complexity
  • Site access
  • Customisation level
  • Structural steel requirements

Average Oriel Windows Cost in the UK

Existing Opening Installation
If you are working with an existing opening, you may expect to pay approximately:

£3,000–£5,000

This typically includes:

  • Bespoke window manufacturing
  • Structural glazing
  • Aluminium or premium frame systems
  • Installation labour
  • Basic structural support
New Oriel Window Installation From Scratch

If you are adding a completely new oriel window structure to a property, the price can increase significantly.

£7,000+

Costs may rise further depending on:

  • Large projections
  • Luxury finishes
  • Triple glazing
  • Complex steelwork
  • Structural engineering requirements
  • Architectural detailing

Although modern oriel windows require a larger investment compared to standard windows, they can become a stunning architectural feature that adds both value and character to a home.

When designed correctly, an oriel window can transform an ordinary room into a premium living space.

Why Are Oriel Windows More Expensive?

Oriel windows involve more complex engineering and installation compared to standard windows. Unlike regular windows installed flush within a wall, oriel windows project outward and require additional structural support.
Modern oriel windows also commonly use:
  • Silicone bonded structural glass
  • Slimline aluminium frames
  • Concealed structural supports
  • Bespoke fabrication
  • Specialist installation techniques

Structural glazing systems often use load-bearing silicone-bonded glass to create a floating appearance with minimal visible framing.

This modern architectural style increases both manufacturing complexity and installation costs.

Oriel Window Colours & Frame Options

One of the advantages of modern oriel windows is the wide range of colours, finishes, and frame styles available.

Popular Oriel Window Frame Materials

Aluminium Oriel Windows

Aluminium is one of the most popular choices for modern oriel windows because it offers:

  • Slim sightlines
  • Modern appearance
  • Excellent durability
  • Powder-coated colour options
  • Strong structural performance
  • Low maintenance requirements
Timber Oriel Windows

Timber frames provide a more traditional appearance and are often used in heritage or period-style properties.

UPVC Oriel Windows

UPVC may offer a lower-cost alternative, although it is less common for highly contemporary floating oriel designs.

Popular Oriel Window Colours

Modern homeowners increasingly choose contemporary finishes including:

color

Choosing the right oriel window colours and frame options can significantly influence the overall appearance of the property.

How Should You Install an Oriel Window?

Oriel window installation requires careful planning, structural calculations, and specialist expertise.

Because these windows project outward from the building, additional support systems are essential.

  • Window installers
  • Structural engineers
  • Architects
  • Builders
  • Glazing specialists
Professional installation ensures:
  • Structural safety
  • Proper weight distribution
  • Thermal efficiency
  • Weather resistance
  • Long-term durability
  • Compliance with building regulations

How to Support Oriel Windows

Traditional oriel windows were typically supported using decorative brackets or corbels.

The design and placement of support brackets must be carefully considered to ensure proper weight distribution and structural stability.

Modern oriel windows, however, are designed to create a cleaner floating appearance.

In many contemporary systems:
  • Structural steels are concealed
  • Weight-bearing timbers are hidden
  • Support systems are integrated within the floor structure
  • Silicone-bonded glass contributes to the minimalist appearance

This hidden support structure helps achieve the dramatic floating effect that makes modern oriel windows so visually impressive

For many homeowners, the answer is yes.

Modern oriel windows provide several benefits, including:
  • Increased natural light
  • Enhanced external views
  • Unique architectural appearance
  • Improved kerb appeal
  • Premium interior design feature
  • Additional seating space
  • Increased property value

Oriel windows are especially effective in modern homes where homeowners want to create a bold design statement. They are also an excellent way to add interest to properties that may otherwise appear visually plain.
