A Guide to Shaped Windows

When it comes to updating your windows, most people think of standard rectangles, but shaped windows can do so much more than just let the light in. They add personality, highlight architectural features, and give your home a truly bespoke feel.

At ZEN, we know that every special shaped window suits your home, but often these beautiful shaped windows are the old original windows, which need bringing into the 21st century for performance, whilst retaining their beauty. We’ll walk you through the most popular window shapes and how we can create virtually any type of frame to replace your existing shaped windows.

What Are Shaped Windows?

Shaped windows are exactly that, windows that step away from the standard square or rectangular format. They’re custom-made to follow curves, angles, or decorative outlines, and can turn a simple feature into something truly special.

Arched Windows

Arched windows are one of the most elegant and timeless shaped window styles. With a soft curve at the top, they add height and create a sense of grandeur.

• Ideal for period properties and homes with tall ceilings

• Soften harsh lines and add a sense of flow

• Great for hallway landings, stairwells, or large feature walls

• Add architectural interest without overpowering your home

• Available in various arch styles to match your aesthetic

Circular Windows (Bullseye Windows)

Circular windows are compact, stylish, and full of personality. Often used as a design feature, they can make a striking statement in both traditional and contemporary homes.

• Perfect for cottages, bathrooms, stairwells, or loft spaces

• Create a focal point inside and out

• Bring in natural light without taking up too much wall space

• Work well in awkward spaces where other window types won’t fit

• Great for adding a nautical or heritage-inspired touch

Gothic Arch Windows

With their pointed tops, Gothic arch windows are all about drama and elegance. They’re most commonly found in heritage properties, but can also bring a bold, characterful look to a modern home.

• Inspired by church and cathedral architecture

• Add a sense of height and grandeur

• Ideal for historic homes or conversions

• Pair beautifully with stained or decorative glass

• Great for feature walls, entrances, or staircases

Triangular Windows

Triangular windows are bold, sharp, and eye-catching. Often used in A-frame buildings or under roof pitches, they maximise awkward wall spaces with stylish, energy-efficient glazing.

• Great for A-frame houses, attics, or chalet-style homes

• Fit into tight architectural corners or gable ends

• Make excellent use of wall space under angled roofs

• Add a modern architectural flair

• Perfect for feature glazing in vaulted ceilings

Where Else Are Curved Windows Used?

One of the most common — and stylish — uses for curved windows is above front doors.

These semi-circular or arched windows, often called fanlights or arched toplights, help to brighten up entryways and make your front door stand out beautifully.

As you can see in the photo, this subtle curved window adds elegance and balance to the entrance, framing the door with a soft, welcoming touch.

Here’s why they’re so popular above doors:

• They let in more natural light without compromising privacy

• Create a welcoming, open feel to your front entrance

• Enhance curb appeal and make your home’s entrance a standout feature

• Pair beautifully with composite or traditional timber doors

• Customisable shapes and sizes to suit your home’s proportions

Whether you're renovating an older home or upgrading a newer one, a curved window above your door is a simple yet striking way to make a lasting impression.

Bringing Your Shaped Windows into the 21st Century

Many shaped windows we see today are the original features of older homes — beautiful, but often underperforming when it comes to energy efficiency and security. These windows were designed in an era when single glazing and drafty frames were the norm.

While they add charm and heritage value, they can struggle to keep up with the standards of modern living.

That’s where we come in.

At ZEN, we specialise in bringing these unique window shapes into the 21st century. Whether it’s an elegant arch, a quirky bullseye, or a grand Gothic design, we can craft a frame that not only matches the original style but surpasses it in performance.

Using modern materials and glazing options, we ensure your new shaped windows are as practical as they are beautiful — giving you all the character without the compromise.
