French doors for N21 homes
Georgian and Regency homes historically used French doors onto gardens, so traditional glazing bars and suitable colours help new ones sit well in a conservation area.
French doors suit Victorian back rooms and kitchen extensions where the opening is too narrow for bifolds, giving a full-width opening from two hinged leaves. On 1930s semis, replacing a rear window and the wall below with French doors needs a properly sized lintel, so the structural work must be planned and approved.
These are houses where originality matters: mock-Tudor details, stained glass toplights and wide bays. We take care to match them rather than fit standard flat frames. The Hertford Loop line runs through, though most roads are quiet. N21 is about 3.1 miles from our factory.
French doors are a pair of hinged doors that open together to connect a room with the garden, patio or balcony. Available in uPVC and aluminium, they suit homeowners wanting a wide, classic opening without the space needed by bifold or large sliding door systems.
- Wide, classic opening to the garden
- Both leaves open fully for access
- Side panels can add extra light
Questions from N21
Do I need planning permission for french doors in N21?
Replacing existing French doors or a back door on a house is usually permitted development and covered by FENSA, but forming a new or wider opening needs Building Regulations approval, and flats or listed buildings may need consent.
How soon can you fit french doors in N21?
Lead times vary by product and workload — confirmed with your quote. Being about 3.1 miles from our factory makes surveys, fitting days and aftercare visits easy to arrange.
What is the difference between French doors and bifold doors?
French doors are two hinged leaves, so the opening is limited to their combined width. Bifold doors use several panels that fold and stack to one side, opening up a much wider space. French doors are simpler and often suit narrower openings, while bifolds suit wider rear elevations.
Can I see samples before I decide?
Yes. Our showroom is at Unit G, 1 Anthony Way, London N18 3QT (Mon–Fri 8am–5pm), about 3.1 miles from N21. We can also bring samples to your home in N21 at the free survey.
