What sliding doors for new openings offer homes in Greenwich
Before you settle on a door type, it helps to know what sliding doors for new openings do well and what to check before you order.
Thinking about a wider opening in Greenwich 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 Greenwich 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.
- 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.
- 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.
How much sun will a door in Greenwich get?
Because Greenwich sees long summer days (about 16 h 38 min) and short winter ones (about 7 h 50 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.
What should you budget for sliding doors for new openings in Greenwich?
Guide prices cover the door and forming the opening — steel beam, padstones, making good and structural calculations — fitted, including VAT. Building Control fees are set by your council and are extra.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 2.4 m | 2 panels | £7,895–£8,895 |
| 3.6 m | 3 panels | £9,695–£10,895 |
| 6.0 m | 4 panels | £13,295–£15,095 |

Timescales for sliding doors for new openings in Greenwich
Surveys in the SE10 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.
Do you need approval in Greenwich?
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.
Choosing the specification
- Low threshold detail. Adjusting floor and outside levels during the building work to allow a lower sill.
- Temporary door or boarding. A secure, weathertight closure while the made-to-measure door is being manufactured.
- Concealed steel. Setting the beam so it sits above the ceiling line, giving a cleaner head detail inside.
Questions about sliding doors for new openings in Greenwich
How soon can you survey in Greenwich?
Surveys in the SE10 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.
Why does beam deflection matter for sliding doors?
Beam deflection matters because a sliding door needs a straight, level head to run properly. Every beam bends slightly under load, and if it bends too much the frame can be squeezed, making panels stiff or causing them to bind. Telling the structural engineer that a large sliding door will go underneath allows them to design a stiffer beam.
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.
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.
