Stunning Origin aluminium French doors and windows for a Derbyshire extension

Origin OB36 Soho French doors

The Origin OB36 Soho French doors are part of Origin's premium aluminium range. French doors are a classic choice that open outwards (or inwards) in pairs from the centre, giving you a wide, unobstructed opening into the garden.

For an extension like the Davies', the benefits are huge:
• Ultra-slim 84mm sightlines for maximum glass
• Steel-look horizontal glazing bars provide the trending industrial feel
• An eight-point locking system for peace of mind
• U-values as low as 0.78 W/m²K (meaning less heat escapes the room)
• Won't warp, rot or swell over time
• Incredibly easy to clean

Origin OB36 Soho casement windows

To match the doors perfectly, we fitted Origin OB36 Soho casement windows to the side of the doors. Casement windows are hinged at the side or top (in this case, the top) and swing open like a little door, giving you brilliant ventilation and a clear view outside. You can open them fully to let a summer breeze in or just pop them ajar for a bit of fresh air.

The benefits for the Davies' extension included:
• Identical slim sightlines to the doors for a fully uniform look
• Excellent airflow and weather sealing
• Tight thermal breaks to keep warmth locked in
• A crisp, architectural finish that complements the doors
• A choice of over 150 RAL colours to suit any taste

Why choose aluminium?

Aluminium is a fantastic material for extensions because it's incredibly strong while being surprisingly lightweight. This means frames can be made much slimmer than uPVC or timber, so you get more glass and more light. It's also powder-coated, so it doesn't need repainting, sanding or treating year after year.

Aluminium won't rust, rot or warp, and it handles British weather brilliantly. For a modern extension where you want a clean, architectural look combined with long-term durability, aluminium is hard to beat. It's a premium choice that genuinely lasts decades with barely any maintenance at all.

Why the Origin range?

We're proud to be an Origin Premium Partner, which is actually how the Davies family found us in the first place. Origin is a British manufacturer based in Buckinghamshire, designing and building their aluminium doors and windows right here in the UK. That's a big part of why their products are so in demand. They have shorter lead times and products built specifically for UK homes and weather.

Origin also back their products with a generous guarantee of up to 20 years, which tells you everything you need to know about how much faith they have in what they make. From the hardware to the powder coating, every detail is top-notch.
