New and widened openings for sliding doors across Norfolk
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:
Turning a Norfolk kitchen window into a door to the garden? Check where drains, gullies and air bricks sit outside, because they can affect the new threshold.
Living in a Norfolk 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.
- 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.
- Structural calculations are included in the guide price, and the Building Regulations application is handled as part of the project, so you are not left coordinating engineers and inspectors.
- 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.

Daylight and glass in Norfolk
In Norfolk the shortest day has roughly 7 h 37 min of daylight and the longest about 16 h 52 min. The noon sun sits near 14° above the horizon in winter and 61° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.

Approvals in England
In England, forming or widening an opening is structural work that needs a Building Regulations application, structural calculations and usually a steel beam on padstones. The new door is also a controlled fitting (U-value 1.4 W/m²K or better if more than 60% glazed). If steelwork bears on a party wall, the Party Wall etc. Act 1996 may apply.
Questions about sliding doors for new openings in Norfolk
How soon can you survey in Norfolk?
Surveys in Norfolk 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.
Do I need planning permission for a new opening?
Planning rules for altering an elevation depend on the property and where you are, so it is worth checking with your council before you commit. Flats, listed buildings and properties covered by an Article 4 direction are the most likely to need consent. Wales and Scotland have their own planning rules. Our planning guide sets out the questions to ask.
How long does it take to form a new opening?
Forming or widening an opening typically involves 3–5 days of building work, including propping, cutting out, installing the steel and padstones, and making good. The sliding door is then made to the finished opening, which typically takes 4–6 weeks for aluminium, so a secure temporary closure is fitted in between. The door itself typically goes in within one to two days.
Do I need building regulations to widen a door opening?
Yes, forming or widening an opening is structural work and needs a Building Regulations application in England, supported by structural calculations. Building Control inspects the work, typically including the steel and its bearings. In Scotland a building warrant is needed. Wales and Northern Ireland follow their own building regulations through local authority or district council building control.
