Planning basement & cellar steels in Newtownards
If you live in Newtownards, basement & cellar steels can usually be planned and priced after a single survey visit. The wider Ards and North Down area is covered as well. We cover BT23, and we fix the price in writing once the layout and scope are agreed.
Turning a cellar into a habitable room, or digging a new basement, nearly always means moving or removing walls that hold up the rest of the house. Steel beams and columns take over that support, often while the existing walls are being deepened by underpinning and the space is protected against water.
Key points for your project
- Getting steel into a basement means lowering it through a lightwell, a stair opening or a temporary hole in the ground floor. Long beams may be designed in bolted sections so they can be handled in tight below-ground spaces.
- Underpinning deepens the existing foundations so walls can go lower, and a specialist carries it out in a strict bay-by-bay sequence. Steelwork has to fit around that sequence, which is why the engineer plans the two together from the start.
- Temporary works for basements are more involved than for a single opening. The design covers propping the house above, supporting the sides of the excavation, and keeping loads off freshly cast concrete until it has gained strength.
- Converting a cellar into a habitable room is building work needing building regulations approval, covering structure, fire escape, ventilation and damp protection. Digging out a new basement may also need planning permission, depending on the council and the scale of the work.
- Basement projects run for weeks rather than days, and the steel goes in at set points during the dig. Noise, spoil removal and deliveries peak during excavation, and with careful planning the house above can often stay occupied.
What happens, step by step
Survey in Newtownards
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
A full plans application or building notice goes to Ards and North Down Borough Council under the Building Regulations (Northern Ireland) 2012 before work begins.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Building control and neighbours in Newtownards
Building control in Newtownards is run by Ards and North Down Borough Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.
The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.

Local questions answered
Do I need a party wall agreement for basement & cellar steels in Newtownards?
There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.
Do you cover Newtownards for basement & cellar steels?
Yes. We carry out basement & cellar steels in Newtownards and the BT23 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Can I stay at home while basement steels are installed?
Many people do, particularly for cellar conversions where the dig is limited. Expect noise, dust and deliveries during the heavier stages, and some rooms above may be out of use while props are in place. For large excavations, moving out for part of the programme can be more comfortable.
Do I need steel beams for a cellar conversion?
Often, yes. If any cellar walls are being removed or opened up, or the ground floor above is being altered for a stair or lightwell, steel beams and columns are usually needed to carry the house above. A structural engineer looks at the layout and loads and specifies the steelwork.
How is steel protected from damp in a basement?
Steel below ground is protected against corrosion as the engineer specifies, which may mean a heavier-duty paint system or galvanising. It is also kept on the dry side of the waterproofing where possible, and fixings through the waterproofing are detailed so they do not let water in.
