Corner sliding doors in Hendon: what to know
The right door depends on the opening, the room and the way you use the garden. Here is how corner sliding doors tend to work out in practice:
If you are planning a wraparound extension in Hendon, designing corner sliding doors in from the start lets the engineer size the corner steelwork alongside the roof.
On any corner installation in Hendon, the survey records floor and patio levels along both walls, because a terrace that falls differently on each side changes the threshold detail.
- Daylight reaches the room from two directions, which keeps a deep extension brighter through the day as the sun moves round the house.
- Low or flush thresholds can run around both elevations, giving one continuous level line from the floor inside to a terrace that wraps the corner.
- When closed, the two corner panels interlock and lock together, so the glass corner stays weathertight and secure without a visible column.
Planning glass for the light in Hendon
The midday sun over Hendon ranges from about 15° at the winter solstice to about 62° at midsummer. Low-angle winter light reaches further into a room through a tall door, which is one reason taller panels are worth considering; on south or west walls, pair them with solar-control glass.
Corner sliding doors prices in Hendon
Pricing does not change because you are in Hendon: the ranges below include fitting, structural calculations and VAT. The steelwork that supports the corner is designed by the engineer and priced after survey, because it depends on the building.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 4.0 m | 4 panels | £10,295–£12,495 |
| 4.8 m | 4 panels | £11,495–£13,995 |
| 6.0 m | 6 panels | £13,395–£16,295 |

How fitting works in Hendon
Here is the usual sequence in Hendon: guide price, free survey, written quote, any building work, then manufacture (typically 4–6 weeks for aluminium, 6–8 weeks for slimline or lift and slide corners, from survey sign-off). Fitting typically takes 1–2 days for the door, after 3–5 days of structural building work. Nearby, we also survey in Golders Green, Finchley and Mill Hill.
Do you need approval in Hendon?
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.
Finishes and extras for corner sliding doors
- Threshold. Standard, low or flush thresholds, with drainage detailed along both elevations.
- System type. Standard aluminium, slimline or lift and slide corner systems, depending on panel size and the sightlines you want.
- Roof junction. Head details coordinated with flat roofs, roof lanterns or pitched roofs so steel, frame and roof meet neatly.
Questions about corner sliding doors in Hendon
Can you match other doors and windows in my Hendon home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
How much do corner sliding doors cost?
Corner sliding doors start from a guide price of £8,695 for 3 m of combined width across both walls, fitted, inc VAT, at standard 2.1 m height. A 4.8 m combined corner is a guide £11,495–£13,995, and 8 m combined is around £16,495. Structural steel for the post-free corner is priced separately, and the final price is fixed in a written quote after survey.
How big can a corner sliding door be?
A corner sliding door in our range typically covers about 3 m to 8 m of combined width across both walls, usually four panels up to about 4.8 m and six panels above that. The two sides do not need to be equal. Panel height starts at the standard 2.1 m and can go taller depending on the system, which is confirmed at survey alongside the structural design.
Can I add a corner sliding door to an existing house?
A corner sliding door can be added to an existing house, but it is a structural project rather than a door swap: the corner of the building has to be rebuilt with engineered steel to carry the load where the post or wall used to be. It is usually done as part of an extension or rear remodel, and a survey plus an engineer's assessment confirm what the structure above needs.
