French doors that open onto Southampton gardens
The interwar semis of Highfield, Bassett and Bitterne almost always sit above a rear garden that would suit a set of French doors better than the original single-leaf back door. Legacy Windows sends your measurements to three Southampton door specialists who quote a fixed supply-and-fit price using UPVC, engineered timber or a slim aluminium equivalent.
Why locals in Southampton choose Legacy Windows
- Typical 2026 pricing runs from around £1,365 for a compact UPVC pair to £3,360 for a wide aluminium set, based on Southampton’s slightly above-average trade rates.
- Every matched fitter is FENSA or CERTASS registered, so the building notice paperwork is handled without your involvement.
- Doors are specified to Part L 2022 with a Ud value of 1.4 W/m2K or lower, and to Part Q where an external door forms part of an extension.
- Threshold heights are quoted against Approved Document M, meaning a low-rise option is available if wheelchair or pram access matters.
- Multi-point espagnolette locking with anti-snap cylinders is included as standard, matching Secured by Design guidance.

Frequently asked questions
Do French doors need planning permission in Southampton? Not usually if they replace an existing opening or are added to a rear wall under permitted development. Article 4 directions in the Old Town or Bassett Green conservation areas remove those rights, so check with Southampton City Council before you commit. Front and side elevations always merit a call to planning.
What is the difference between French doors, sliding patio doors and bifolds? French doors are the traditional two-leaf option with a central mullion or a slim closer bead. Sliders offer a wider glass area on a fixed rail, and bifolds fold back to give the widest opening. French doors typically cost the least of the three.
Should I specify tempered or laminated glass? Both meet Part K on impact safety. Laminated glass adds security and stays intact if broken, and it is standard on our panel for ground-floor Southampton installations.
