What are French doors?

French doors are a timeless architectural feature known for their double-door configuration, classic proportions, and elegant glazed panels. Traditionally made from timber, they consist of two matching doors that open from the centre, either inward or outward, offering a grand yet graceful way to access the outdoors.

Often installed at the rear of a property, French doors are a popular choice for garden-facing living rooms, dining areas, kitchen extensions, and even upper-floor balconies. Their glazed design maximises natural light, enhances sightlines, and fosters a seamless connection between interior and exterior spaces.

For period properties or homes with classic architecture, they’re a perfect way to maintain authenticity while enhancing usability and comfort.

Why choose French doors from Nine Zero?

We craft French doors with care, precision, and a deep respect for architectural heritage. Whether you’re restoring a listed Georgian townhouse or enhancing a period-style new build, our timber French doors are designed to complement and elevate a property’s character. 

Each set is made using FSC-certified, sustainably sourced timber, ensuring not only long-lasting quality but also environmental responsibility.
