French Grey Slimline Sliding Doors for a Traditional Atrium Extension, Waterlooville

Location: Waterlooville, Hampshire

Located in the charming village of Clanfield, this beautifully designed atrium extension showcases how thoughtful bespoke glazing can transform a family home. Combining traditional architecture with contemporary detailing, the project delivers a refined, light-filled living space that enhances both comfort and style. With expansive glass atriums and a carefully considered atrium roof, the extension creates a seamless connection between the home and garden while respecting the character of the original property.

A Vision for a Traditional Yet Light-Filled Extension

The homeowners of this detached property in Waterlooville set out to extend their home with a traditional atrium design to bring in more natural light without compromising its classic appearance. Their goal was clear: create a bright, open sanctuary that felt elegant, practical, and in keeping with the existing architecture.

After visiting the Homebuilding & Renovating Show, where Thames Valley Windows exhibited alongside Internorm, the homeowners were inspired to explore premium glazing solutions further. A visit to our Bracknell showroom allowed them to experience our sliding door systems first-hand and discuss their vision in detail with our designer, Paul Mills. Through a collaborative design process, we recommended a solution that balanced aesthetics, performance, and long-term value.

Choosing the Right Sliding Door System

Following careful consideration, the homeowners selected the Solarlux Ecoline sliding door system, finished in powder-coated RAL7032 French Grey. This colour choice is a sophisticated, soft neutral with subtle undertones that complement the home’s red brickwork beautifully, adding a timeless yet contemporary edge.

The installation features two large-format, two-panel sliding doors that dominate the rear elevation of the atrium extension. These slimline systems are designed to maximise glazing while minimising visible frame, creating uninterrupted views and allowing natural light to flood deep into the living space.

German Engineering Performance with Elegant Design

The Solarlux Ecoline system represents the latest generation of sliding doors, combining precision engineering with minimalist aesthetics. Designed for large openings, it accommodates expansive panes of glass while maintaining exceptional thermal performance.

With a central interlock of just 55mm, the system delivers a clean, uniform sightline that enhances the sense of openness within the glass atriums. The thermally insulated profile ensures year-round comfort, while high-quality stainless-steel carriages allow the large panels to glide effortlessly with minimal effort.

Panels can reach up to 2,700mm in width and 2,500mm in height, supporting substantial glazing areas that define the extension’s architectural impact. Whether configured on double or triple tracks, the system offers flexibility in design, enabling panels to stack neatly and open up the entire space to the outdoors.

Maximising Natural Light with Glass Atriums

At the heart of this project is the desire to bring in as much natural light as possible. The combination of slimline sliding doors and a thoughtfully designed atrium roof ensures the space is bright throughout the day, regardless of the season.

The glass atriums create a striking visual feature while serving a practical purpose, capturing daylight from above and enhancing the feeling of openness. This influx of light transforms the extension into a welcoming, uplifting environment that supports modern family living.

By integrating large panes of glazing with minimal structural interruption, the design blurs the boundary between inside and out. Garden views become part of the interior experience, reinforcing a sense of calm and connection to nature.

A Seamless Connection Between Home and Garden

This atrium extension was designed to do more than just add space—it redefines how the homeowners interact with their surroundings. The expansive sliding doors open up the entire elevation, creating a fluid transition between indoor and outdoor areas.

Flush thresholds and carefully integrated drainage ensure both practicality and visual continuity, while the option to conceal outer frames within wall cavities enhances the minimalist finish. Every detail has been considered to maintain clean lines and a cohesive look.

The result is a versatile living area that adapts effortlessly to different uses, from everyday family life to entertaining guests, all while maintaining a strong visual connection to the garden.

A Bespoke Glazing Solution That Stands the Test of Time

Manufactured in Germany, Solarlux systems are known for their durability, precision, and long-term performance. This project demonstrates how high-quality materials and expert installation can deliver a solution that not only looks exceptional but performs reliably for years to come.

The combination of advanced engineering, elegant design, and a carefully selected colour finish ensures the extension remains both functional and visually appealing well into the future.

Transforming Living Spaces with Thoughtful Design

This Waterlooville project highlights the importance of a bespoke approach to glazing. By combining slimline sliding doors, glass atriums, and a well-designed atrium roof, the homeowners have achieved a space that feels both luxurious and welcoming.

Flooded with natural light and defined by clean architectural lines, the extension enhances the overall living experience while adding tangible value to the property. It stands as a testament to what can be achieved when design, craftsmanship, and innovation come together seamlessly.

Homeowner Experience and Results

1. What helped you make your decision? Price/quality/features, etc?

All three points. We loved the quality, particularly the ease of movement, and the price was competitive too. Also, we had confidence that TVW could deliver a top-end finish.

2. Results – did it meet aspirations, what impact has the installation had – lifestyle change, property value, space added, etc.

The atrium extension has given us lots of additional living space. The windows have both met and exceeded our expectations. We use this space every day, but it’s also a great social space. Lately, the weather’s meant we’ve spent a good deal of our time outside, but we find that the doors look fabulous from outside too! A recent valuation shows that we’ve recouped our costs and then some, so the extension and windows were a sound investment.

3. Why did you choose TVW, and what made us unique among other providers?

Paul really sealed the deal for us. He took the time to talk through all options, answered our many questions, and ensured we chose the product that was right for us.
