Are corner sliding doors right for your Gerrards Cross home?
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:
A Gerrards Cross garden that sits to the side as well as the rear of the house is where a post-free corner earns its place, opening the room towards both.
Corner glazing changes how a Gerrards Cross home looks from neighbouring gardens, so confirm the planning position for the extension with your designer or the local planning authority before ordering.
- With no post at the corner, sliding both sets of panels back opens the meeting point of two walls completely, so the room spills straight onto the patio.
- Because panels slide rather than fold, the corner can be opened on one side only, keeping the other side closed as a wind screen on cooler days.
- 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.
Sunlight, glass and orientation in Gerrards Cross
Daylight in Gerrards Cross runs from about 7 h 49 min in December to 16 h 39 min in June, with the noon sun at roughly 15° and 62° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.
Guide prices for corner sliding doors in Gerrards Cross
These figures are for the door supplied and fitted, with the engineer's structural calculations, including VAT. The steelwork that supports the corner is designed by the engineer and priced after survey, because it depends on the building. Your price is fixed in a written quote after survey.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 3.0 m | 4 panels | £8,695–£10,595 |
| 3.6 m | 4 panels | £9,595–£11,795 |
| 8.0 m | 6 panels | £16,495–£20,095 |

How fitting works in Gerrards Cross
A surveyor visits your Gerrards Cross home to check the wall, the structure above and the floor levels, and talks through glass and finish. Any building work is planned to the engineer's design, the door is made to the finished opening sizes — typically 4–6 weeks for aluminium, 6–8 weeks for slimline or lift and slide corners, from survey sign-off — and fitting usually takes 1–2 days for the door, after 3–5 days of structural building work.
Do you need approval in Gerrards Cross?
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.
Options to consider for your corner sliding door
- Roof junction. Head details coordinated with flat roofs, roof lanterns or pitched roofs so steel, frame and roof meet neatly.
- System type. Standard aluminium, slimline or lift and slide corner systems, depending on panel size and the sightlines you want.
- Colours. Single or dual colour powder coating, so the outside can match the extension cladding or render.
Questions about corner sliding doors in Gerrards Cross
Is the price different in Gerrards Cross?
No. Guide prices for corner sliding doors are the same across mainland Britain, including Gerrards Cross. The fitted price depends on size, system, glass and finish, and any structural work, all fixed in your 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.
How long does a corner sliding door project take?
A corner sliding door typically takes 4–6 weeks to manufacture in standard aluminium and 6–8 weeks for slimline or lift and slide systems, from survey sign-off. The steelwork and building work usually take 3–5 days before the door goes in, and fitting the door takes 1–2 days. Engineer design and approvals come first, so the door is ordered once the steel is designed.
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.
