Aluminium Glazed Extension Renovation in Stour Row, Dorset
Replacing an Ageing Timber Structure with a Stunning New Aluminium Glazed Extension
When homeowners invest in improving their property, they want a solution that not only looks beautiful but is built to last. This recent project in Stour Row, Dorset, perfectly demonstrates how replacing an ageing timber glazed structure with a modern aluminium system can completely transform both the appearance and performance of a home.
At Goldhill Glazing, we were asked to modernise the rear elevation of this beautiful Dorset property by removing the existing timber-framed glazed structure, replacing the structural timber supports, and installing bespoke aluminium glazing while retaining and supporting the existing roof.
The finished result is a bright, contemporary living space that floods the home with natural light, frames the surrounding countryside views and provides decades of low-maintenance performance.
Whether you’re looking for aluminium windows in Dorset, aluminium doors in Shaftesbury, replacement glazed extensions, structural glazing, or a company experienced in working alongside structural carpenters, this project showcases exactly what can be achieved.
The Customer’s Requirements
The existing timber glazed structure had served the property well for many years, but like many older timber installations, it had begun to show its age.
The homeowner wanted to:
- Replace the ageing timber glazing with modern aluminium frames.
- Retain the existing roof.
- Improve thermal efficiency.
- Increase natural light.
- Reduce future maintenance.
- Modernise the appearance of the property while respecting its traditional character.
- Create uninterrupted views across the beautiful Dorset countryside.
Rather than replacing the entire extension, we developed a solution that retained the existing roof structure while replacing everything beneath it.
This approach offered excellent value for money while completely transforming the appearance of the property.
Surveying the Project
Every successful installation starts with a detailed survey.
Because this wasn’t simply a window replacement, careful planning was essential.
Our survey included:
- Measuring every opening to the millimetre.
- Checking structural load paths.
- Confirming how the existing roof would be temporarily supported.
- Coordinating with the carpenter replacing the structural timbers.
- Designing bespoke aluminium frames to fit perfectly between the new structural posts.
This collaborative approach meant that once the new structural timber framework had been installed, our aluminium glazing could be fitted quickly and accurately.
Removing the Existing Timber Structure
The original timber glazing had reached the end of its useful life.
Over time, timber structures are exposed to changing weather conditions, moisture, movement and general wear. Although timber remains an attractive building material, older glazed structures often require extensive maintenance and can eventually become less energy efficient than modern systems.
The existing glazed sections were carefully removed to expose the structural framework beneath.
Because the roof above was remaining in place, the work required careful sequencing to ensure the structure remained safely supported throughout the renovation.
This is not a project that can simply be treated as a standard window replacement—it requires experience, planning and close cooperation between trades.
Installing New Structural Timber Supports
One of the most important stages of this project was replacing the structural timber supports.
Working alongside an experienced carpenter, the old structural timbers were removed before new load-bearing timber posts and beams were installed to safely carry the weight of the existing roof.
The new structural framework provides a solid foundation for the aluminium glazing while maintaining the integrity of the roof above.
Once complete, the structure was significantly stronger and ready to accept the new bespoke aluminium frames.
Projects like this demonstrate the importance of using experienced professionals who understand both glazing and structural considerations.
Bespoke Aluminium Glazing Installation
With the new structural framework complete, we installed a fully bespoke aluminium glazing system manufactured specifically for this property.
The installation included:
- Large fixed aluminium glazed panels.
- Slimline aluminium French doors.
- Full-height side glazing.
- High-level feature glazing beneath the roofline.
- Thermally broken aluminium frames.
- High-performance double glazing.
- Modern anthracite grey powder-coated finish.
The slim aluminium sightlines maximise the amount of glass while allowing the surrounding landscape to become part of the living space.
From inside the property, the difference is remarkable.
Natural light now floods the room throughout the day while uninterrupted views create a far more open and spacious feel.
Why Aluminium?
Strength
Aluminium is incredibly strong, allowing much larger areas of glass with slimmer frames.
More Natural Light
Because aluminium requires less material to achieve structural strength, homeowners benefit from significantly larger glazed areas.
More glass means:
- More daylight.
- Better views.
- A greater feeling of space.
Thermal Performance
Modern thermally broken aluminium frames combined with energy-efficient double glazing provide excellent insulation.
This helps keep homes warmer during winter while reducing heat loss and improving comfort all year round.
Low Maintenance
Unlike traditional timber frames, aluminium does not require regular painting.
A simple clean is usually all that’s needed to keep the frames looking their best.
Long Lifespan
Powder-coated aluminium is designed to last for decades without warping, rotting or rusting.
Improving Energy Efficiency
One of the biggest benefits of replacing older glazing is improved energy performance.
The new aluminium glazing installed on this project offers:
- Improved insulation.
- Reduced draughts.
- Better weather resistance.
- Lower heat loss.
- Increased comfort.
Combined with modern glazing technology, homeowners can enjoy a more energy-efficient property throughout every season.
A Contemporary Finish That Complements a Traditional Home
Although this property is full of traditional Dorset character, the modern aluminium glazing sits beautifully alongside the natural stone walls and new structural timber posts.
The contrast between warm natural timber and anthracite aluminium creates a striking architectural appearance while respecting the property’s original style.
Rather than looking out of place, the new extension feels as though it has always belonged there.
Working with Structural Carpenters
Projects involving structural glazing often require close collaboration between multiple trades.
For this renovation we worked alongside specialist carpenters who installed the new structural timber framework before our glazing installation.
By surveying the project together and coordinating measurements before manufacture, every aluminium frame fitted perfectly into the finished structure.
This level of planning reduces delays, improves quality and ensures the finished result meets the highest standards.

Frequently Asked Questions
Can you replace a timber glazed extension with aluminium?
Yes. In many cases, the existing glazed structure can be removed and replaced with modern aluminium frames. If the roof is structurally sound, it may be possible to retain it while replacing the supporting structure and glazing.
Are aluminium windows better than timber?
Both materials have their strengths, but aluminium offers excellent durability, slim sightlines and very low maintenance. It’s an ideal choice for homeowners wanting a modern appearance with long-term performance.
Are aluminium frames energy efficient?
Modern thermally broken aluminium frames combined with high-performance double glazing provide excellent thermal efficiency and can significantly outperform many older glazed systems.
How long do aluminium windows last?
Quality powder-coated aluminium windows can last for several decades with minimal maintenance, making them one of the most durable glazing options available.
Do I need a FENSA registered installer?
Using a FENSA registered installer gives homeowners confidence that replacement windows and doors comply with current Building Regulations and are installed to recognised industry standards.
