New and widened openings for sliding doors in Devizes: what to know
The right door depends on the opening, the room and the way you use the garden. Here is how sliding doors for new openings tend to work out in practice:
Thinking about a wider opening in Devizes but unsure of the size? Mark it out on the wall inside and out with tape, then picture the furniture and the view before you decide.
Living in a Devizes flat? Structural changes to an external wall almost always need the agreement of the building's owner or the other owners, so speak to them first.
- If the work affects a party wall, notice can be served under the Party Wall etc. Act 1996 (England and Wales) before it starts, avoiding disputes with neighbours later.
- The door is measured from the finished opening rather than from drawings, so it fits the opening as built, not as it was intended to be built.
- Widening a standard patio opening to a larger span can transform how a room connects to the garden, giving a wall of glass rather than a doorway.
How much sun will a door in Devizes get?
Because Devizes sees long summer days (about 16 h 37 min) and short winter ones (about 7 h 51 min), the elevation your door faces makes a real difference. With the midday sun at about 15° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.

Survey, manufacture and fitting around Devizes
Surveys in the SN10 district are booked at a time that suits you. Once the opening is ready and measured, manufacture is typically 4–6 weeks for the door after the opening is measured; building work scheduled around approvals; on fitting day the frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 3–5 days of building work, then 1–2 days to fit the door.
Rules for sliding doors for new openings in England
A new or wider opening in England needs Building Control approval for the structural work as well as compliance for the door itself under Approved Documents L and K. Expect structural calculations, a steel beam and, where a party wall is involved, notices under the Party Wall etc. Act 1996.
Options to consider for your sliding door for a new opening
- Temporary door or boarding. A secure, weathertight closure while the made-to-measure door is being manufactured.
- Low threshold detail. Adjusting floor and outside levels during the building work to allow a lower sill.
- Window to door conversion. Cutting down below an existing window to form a door opening to the garden.
Questions about sliding doors for new openings in Devizes
How soon can you survey in Devizes?
Surveys in the SN10 district are booked at a time that suits you, and we offer survey dates when we reply to your enquiry. After you approve the written quote, manufacture is typically 4–6 weeks for the door after the opening is measured; building work scheduled around approvals.
Can you turn a window into a sliding door?
Yes, a window opening can usually be extended down to the floor and often widened to take a sliding door. The work involves removing the masonry below the window, forming a new threshold, and fitting a steel beam or lintel if the opening is widened. Drains, air bricks and floor levels outside need checking, and the work needs a Building Regulations application.
Do I need a steel beam for sliding doors?
A widened or new opening usually needs a steel beam or a suitable lintel to carry the wall and anything above it, and for wider openings a steel beam is the usual answer. A structural engineer chooses the size and bearing details based on the loads. The beam is placed on padstones at each end to spread its load into the masonry.
Does the Party Wall Act apply to my new opening?
The Party Wall etc. Act 1996 (England and Wales) may apply if the new steel beam bears on, or is cut into, a wall you share with a neighbour, as is common in semi-detached and terraced houses. If it applies, you must serve notice on the neighbour before the work starts. A rear wall entirely on your own property is less likely to be affected.
