Single Doors

Customise your design with heritage-style single doors, featuring flexible transom and bar layouts. Whether you want a classic grid pattern or larger panes with fewer bars, we can tailor the sightlines and transom heights to suit your space and style.

French Doors

Our French door sets include a handle block on the primary leaf, finished with your choice of hardware. The secondary leaf can be configured with or without a matching handle — giving you full control over symmetry, function, and finish.

Configurations & Side Panels

Our aluminium external doors can be paired with matching side panels, toplights, or fixed frames to suit larger openings. This modular approach allows you to create full-width glazed façades or balanced doorways that retain character while enhancing natural light and garden views.

For added functionality, you can also incorporate opening window sashes into the side panels — ideal for natural ventilation in kitchen diners, garden rooms, or heritage refurbishments.

Heritage Rennovation

Here we have a charming cottage installation on the edges of the Peak District. The weathered stonework is beautifully complemented by our slim, steel-look external doors and windows.

It’s a perfect example of how heritage-inspired design can respect a building’s original character while adding modern comfort and energy efficiency. The timeless black finish and elegant glazing bars preserve the period aesthetic, while the performance of aluminium brings lasting warmth, security, and ease of use.

Modern Rennovation

Here we have a modern installation in a leafy Lancashire village, where smooth, subtly rendered walls and crisp black aluminium frames create a striking contemporary look. The large glass panels flood the home with natural light, forming a seamless connection between the interior and the garden.

This project perfectly shows how our steel-look aluminium doors and windows enhance modern properties—delivering slim sightlines, thermal efficiency, and long-lasting durability. The design feels refined and minimal yet warm and inviting, blending the best of contemporary living with timeless, understated style.

External Doors for Internal Use

Our external steel-look doors aren’t just for patios and garden rooms — they can also be installed inside your home to create stunning room dividers or feature entrances. If you’re happy with either a 3 cm standard threshold or 15 mm low threshold, this option opens up a world of design possibilities.

By choosing an external-grade system indoors, you’ll enjoy:

Superior acoustic performance – double glazing helps reduce noise transfer between rooms.

Full functionality – including the option for working lever handles on the slave door.

Industrial elegance – slim aluminium sightlines with a timeless steel-look finish.

However, if you prefer purpose-built internal doors with ultra-slim thresholds, you can view our dedicated Internal Doors range here.
