Are sliding doors for new openings right for your Holywood home?
Most homeowners choosing sliding doors for new openings want the same things: more light, a clear view and a door that is easy to live with.
Where a Holywood house has a bay, chimney breast or upstairs window directly above the planned opening, the engineer will need to account for it in the steel design.
Turning a Holywood kitchen window into a door to the garden? Check where drains, gullies and air bricks sit outside, because they can affect the new threshold.
- A structural engineer sizes the steel beam and padstones for the actual loads above, so the opening is designed rather than guessed.
- Making good the reveals and head after the steel goes in leaves a square, plumb opening, which is what a precision-made sliding door needs to run smoothly.
- 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.
Light and sun in Holywood
At the latitude of Holywood, the midday sun climbs to about 59° in late June but only about 12° in late December, when daylight lasts around 7 h 14 min against 17 h 17 min in midsummer. A south-facing sliding door for a new opening lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.

From survey to fitted door in Holywood
Nothing is ordered until you sign off the surveyed specification. The door is made from the finished opening sizes (typically 4–6 weeks for the door after the opening is measured; building work scheduled around approvals), and fitting usually takes 3–5 days of building work, then 1–2 days to fit the door. If you are in Newtownabbey or Belfast, the same process and prices apply. Holywood is in an area we cover by arrangement: the survey is still free, and survey dates, delivery and any travel cost for delivery and fitting are confirmed in your quote before you order.
Rules for sliding doors for new openings in Northern Ireland
Opening up a wall in Northern Ireland needs district council building control approval and structural calculations. We take on this work in Northern Ireland by arrangement.
Choosing the specification
- Concealed steel. Setting the beam so it sits above the ceiling line, giving a cleaner head detail inside.
- Steel beam with padstones. A beam sized by the engineer to carry the wall, floors and roof above.
- Temporary door or boarding. A secure, weathertight closure while the made-to-measure door is being manufactured.
Questions about sliding doors for new openings in Holywood
Is the price different in Holywood?
The door price is the same as anywhere else. Because Holywood is covered by arrangement, any travel cost for delivery and fitting is shown in your quote before you order; the survey itself is free.
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 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.
How much does it cost to widen an opening for sliding doors?
Our guide price for forming or widening an opening is £3,595 for 2.4 m and £4,495 for 4.8 m, covering steel, padstones, making good and structural calculations. The door is priced separately, and Building Control fees are set by your council. All figures are guide prices inc VAT, fixed in a written quote after we survey the wall and see what is above it.
