Before & After | Hurworth-on-Tees 📍

A fantastic transformation for this property in Hurworth-on-Tees, County Durham.
We removed the existing timber doors and replaced them with Sheerline Classic aluminium doors, giving the space a cleaner, more contemporary finish while letting plenty of natural light into the room.

The slim aluminium frames work beautifully with the character of the property, creating a seamless connection between the home and garden.

🏡 A stunning home with serious kerb appeal!

https://marlinwindows.co.uk/s1-aluminium-roof-lantern/

Beautiful brickwork, a striking slate roof and that gorgeous S1 roof lantern make this property a real standout. The large glazed doors and conservatory-style extension bring in plenty of natural light, while the beautifully maintained garden creates the perfect setting for relaxing, entertaining and enjoying the outdoors. 🌿☀️

A fantastic example of traditional character combined with bright, modern living.

What a transformation. 🏡

A full house redevelopment in Eastby, North Yorkshire, featuring substantial rear and side extensions and a complete new glazing package.

We installed Sheerline Classic aluminium windows and doors throughout, alongside a Sheerline S1 roof lantern with remote-controlled Sheervent.

The before-and-after really shows the difference — a complete transformation while retaining the character of the original property.

✨ Before & After – what a transformation! ✨

This wide open-plan opening has been completely transformed with a bespoke AluSpace internal heritage screen and door system.

The slim black aluminium frames create that timeless steel-look aesthetic while the generous glazing keeps natural light flowing between the rooms. The result is clear separation between the spaces without losing the bright, open feel of the home.

Made to measure in Yorkshire, AluSpace offers ultra-slim sightlines, a choice of configurations and over 200 RAL colours and textured finishes.

🏡 On site in Rolleston-on-Dove today!

A great new-build project taking shape, and we’re on site carrying out the survey ahead of the glazing stage.

At Marlin Windows, we specialise in the specification and design of aluminium heritage glazing systems for new-build homes and developments throughout the UK. Working alongside architects, developers, builders and homeowners, we help ensure the glazing complements the architecture while delivering the performance expected from a modern aluminium system.

With the structure and roof taking shape, accurate surveying at this stage helps make sure everything is right before the aluminium windows and doors go into manufacture.

Looking forward to seeing this one progress!

🏛️ MONARCH HOUSE, LEEDS | HERITAGE WINDOWS WITH MODERN PERFORMANCE

We’re proud to be working on the refurbishment of Monarch House on Queen Street, Leeds, a distinctive 1920s commercial building with strong links to the city’s textile heritage.

Marlin Windows are replacing the building’s original steel windows with the Sheerline Classic aluminium glazing system, including some particularly impressive arched and curved window sections.

A key consideration for the planners was retaining the character and proportions of the original steel windows. Sheerline Classic was selected by the planners because its slim aluminium sightlines closely replicate the appearance of traditional steel glazing, while providing the significant benefits of a modern, thermally efficient window system.

The photographs show some of the specialist frames taking shape in our factory before making their way to site — including those fantastic curved heads.

It’s a great example of how heritage appearance and modern performance can work together, helping preserve the architectural character of an historic Leeds building while bringing its glazing firmly into the 21st century.

✨ Another happy customer — and what a transformation! ✨

We love seeing how the right windows and doors can completely change the way a home looks, feels and works.

For this beautiful property, our customer wanted to replace a large window with a door to create easy access from the lounge onto the patio. Because a traditional opening door would have been restricted by the outside wall, we suggested a tilt-and-turn window designed to act as a door — a clever solution that fits the space perfectly while keeping the stunning black-framed look throughout. 🖤

And we were delighted to receive this fantastic Trustpilot review from Marie:

⭐⭐⭐⭐⭐ “Excellent Company”
“We bought our crittal style windows for our conversion and they look fabulous, had so many compliments! … This was a genius idea and it looks amazing. It makes a huge difference to the lounge and to the patio outside which is easily accessible now. Marlin work with you, create fabulous doors and windows, deliver on time and are priced perfectly. Why go anywhere else!”

Thank you, Marie, for such wonderful feedback. We’re delighted with how this project turned out! 🙌

Beautiful design. Practical solutions. Made for the way you live.

The slim black aluminium frames create a striking architectural feature while the generous glazing allows natural light to flow between the rooms. It gives the separation of a traditional wall, without losing that bright, open-plan feeling.

A beautiful way to divide living and dining spaces while adding a contemporary, industrial-inspired finish.
