when one door changes everything
There’s a particular frustration that comes with inheriting someone else’s choices. This Wilmslow bungalow extension had everything going for it – a beautifully considered living space, clean contemporary lines and a garden that deserved to be seen – but the existing sliding patio door let it down. Installed by a previous owner in a different colour to the rest of the property’s glazing, it sat at odds with everything around it, an obvious mismatch in an otherwise well-resolved home.
The solution was straightforward but transformative. We replaced the old door with an AluK S67 four-pane aluminium sliding patio door in RAL 9006 Smoke Grey – a cool, metallic silver-grey finish that matches the property’s existing glazing precisely, finally tying the whole elevation together. The colour is consistent inside and out, which matters in a space where the boundary between interior and exterior is deliberately blurred, and the silver patio handle sits cleanly within the overall aesthetic without drawing unnecessary attention to itself.
The door itself is a 2+2 configuration – two fixed outer panels flanking two sliding inner panels – which maximises the glazed area while keeping the operation smooth and effortless. From inside, the effect is remarkable. Floor-to-ceiling glass floods the room with natural light and frames the garden as if it were part of the living space itself, with the slim aluminium sightlines doing as little as possible to interrupt that connection. From outside, the door sits flush and considered within the flat-roof extension, giving the elevation a coherence it previously lacked.
This is the kind of installation where the impact goes beyond the door itself. By bringing this opening in line with the rest of the property, the whole home feels more intentional – a space where every decision feels like it belongs.

frequently asked questions
The AluK S67 is a premium aluminium sliding door system designed for both residential and commercial applications. It features slim, thermally broken aluminium frames that maximise the glazed area while delivering excellent thermal and acoustic performance. The S67 is available in a wide range of RAL colours and configurations, making it a popular choice for contemporary extensions and renovations where a clean, architectural finish is required.
RAL 9006 Smoke Grey is a cool, metallic silver-grey finish that closely resembles the natural appearance of brushed or anodised aluminium. It’s one of the most popular colours for aluminium doors and windows on contemporary properties, as it complements both modern and traditional exteriors without imposing a strong colour statement. On this Wilmslow installation, RAL 9006 Smoke Grey was specified inside and out to match the property’s existing glazing and bring a consistent finish across the whole elevation.
A 2+2 configuration refers to a four-pane sliding door where two outer panels are fixed and two inner panels slide independently in front of them. This arrangement maximises the overall glazed area of the opening while still allowing the door to be fully opened across a wide aperture. It’s a popular choice for larger openings where a standard two-pane sliding door wouldn’t provide sufficient width or impact.
Aluminium sliding patio doors offer several advantages over uPVC, particularly for larger openings and contemporary properties. Aluminium is significantly stronger than uPVC, which allows for much slimmer frame profiles and larger panes of glass without compromising structural integrity. This results in a cleaner, more refined appearance with more light and less frame visible. Aluminium is also more dimensionally stable over time, less prone to warping or discolouration, and generally considered a more premium finish suited to higher-end renovations and extensions.
