Cork’s new build market has kept a steady pace through 2026. New phases are launching in established commuter towns across the county, as well as in smaller pockets closer to the city. For buyers, that means more choice and more to weigh up. Six developments stand out at the moment, from Carrigtwohill and Midleton in the east to Mallow in the north.
Ard na Sailí, Carrigtwohill
Ard na Sailí is a development by Hegarty Properties and BAM, with 2, 3 and 4 bed houses including semi-detached homes. The layout includes landscaped parks, greenways and recreational areas. Carrigtwohill village, schools and the train station are all close by, and the rail line gives direct access to Cork city and Midleton. Phase three is now open for registrations.
Janeville, Carrigaline
Astra Construction’s Janeville is one of the largest residential developments in Cork. It’s set on a 100-acre site at Shannonpark and is expected to deliver close to 1,000 homes across all phases. The homes are A2 rated, with terraced, semi-detached and detached homes from 2 to 5 bed. The site is on the Cork side of Carrigaline, a short walk from the town centre, with quick routes to Douglas, Mahon Point, Ringaskiddy and the city.
The Old Course, Mallow
The Old Course brings north Cork onto the list. It’s a development of 3 and 4 bed semi-detached homes on the outskirts of Mallow. The homes are A2 rated and use air to water heat pumps, with underfloor heating on the ground floor. They’re covered by a 10-year Homebond structural guarantee. The developer is registered for both Help to Buy and the First Home Scheme, which we’ve explained in our guide to government home buying schemes for Cork first-time buyers.
Ard Griffin, Water Rock, Midleton
Ard Griffin by Clancy Homes offers 2, 3 and 4 bed homes that are A2 rated and fully NZEB compliant. NZEB is the nearly zero energy building standard. Midleton train station is roughly a 12-minute walk away. Once the planned Water Rock station opens, residents will be about three minutes from a platform.
Belview Wood, Maryborough, Douglas
Belview Wood by Cirio Homes sits on an elevated site on Maryborough Hill, with countryside views and Douglas village within walking distance. There’s a broad mix of apartments, duplexes, terraced and semi-detached homes from 1 to 4 bed. All homes are A2 rated and covered by a 10-year Homebond guarantee. Most are eligible for Help to Buy and the First Home Scheme.
A snag inspection is a thorough, room by room check of a new home for defects, poor finishes and workmanship issues before you take the keys. On a well-run site with a high spec, the list may be short, but it’s rarely empty. We’ve covered the most common problems we see in new build homes if you’d like a sense of what typically comes up.
Builders carry out their own checks, and good builders take them seriously. A builder’s check confirms the work against their own standard, though. An independent engineer has no stake in the build, so the report reflects the home as it is. You get a clear, itemised list to share with the builder so any issues can be put right.
Timing matters too. The best point is after practical completion but before you sign the final contracts, while the property is still the builder’s responsibility. That way any remedial work can be agreed and finished as part of the sale. If issues do come up, our guide to what to do if your snag list comes back with issues sets out the next steps.
Whether you’re buying in one of these developments or anywhere else in Cork, BCE Consulting Engineers can carry out an independent snag list inspection before you move in. Get in touch and we’ll arrange a time that suits your handover.
Since the end of July, homeowners across Cork have had a real, workable route to building a granny flat in the back garden without applying for planning permission. For families in Douglas, Ballincollig, or Carrigaline weighing up space for an elderly parent or an adult child struggling to get on the property ladder, that’s a meaningful change. It’s no surprise the new granny flat regulations have drawn so much interest.
Being exempt from planning is only one part of the picture, though. Building regulations, building control, and fire safety requirements all still apply. They’re also the parts people most often overlook once the planning question feels settled. Here’s what still needs working through before anything is built.
A quick recap of what Class 3A allows
The Class 3A exemption, introduced under S.I. No. 340 of 2026, came into force on 27 July 2026. It covers one detached auxiliary dwelling of between 32 and 45 square metres in the rear garden of a house that is the owner’s main residence. At least 25 square metres of private garden has to remain. Any existing sheds or garden structures built under the older Class 3 rules count towards the 45 square metre cap.
The unit must be occupied in conjunction with the main house. It can’t be sold or subdivided separately, and it can’t be used for short-term letting. The work also has to be started and finished before 31 December 2030. We covered the planning side in more detail in our guide to Ireland’s new planning exemptions.
Planning exempt does not mean building regs exempt
In practical terms, a 45 square metre granny flat is a new dwelling. It’s held to the same standards for structure, fire safety, ventilation, drainage, and energy performance as any other home. Before work starts, a Commencement Notice has to be lodged with the local building control authority, and Cork County Council’s building control team handles these for the county. Local authority guidance published since the rules changed indicates that a habitable auxiliary dwelling needs a design certifier, an assigned certifier, and a certificate of compliance on completion.
This is the most common misunderstanding since the rules changed. “Exempt” is heard as “no paperwork”, when really one set of paperwork has been removed and the rest still stands.
Three scenarios, three different answers
Fire safety requirements depend less on the size of the space and more on how it’s used, and whether it forms part of one home or two.
Renting out a spare room in your own home
If you’re letting a bedroom in the house you live in, the property remains a single dwelling. A building used as a dwelling, other than a flat, is exempt from needing a fire safety certificate, so no certificate is needed here. Working smoke alarms and a clear escape route still matter for anyone living under your roof.
A granny flat used by a family member
This is where people tend to assume the least is involved. Say you’re building a 40 square metre unit at the end of the garden in Blackrock for your mother. Because it’s a detached dwelling rather than a flat, it may not need a formal fire safety certificate. It still has to be designed and built to meet the fire safety part of the building regulations, including safe means of escape, fire detection, and adequate separation from the main house and site boundaries. It also goes through building control like any other new home. No certificate doesn’t mean no requirements, which is why this scenario is less clear-cut than it first appears.
Converting a house into a duplex
If you’re splitting an existing house into two units, one above the other, the building is no longer treated as a single private dwelling. Each unit becomes a flat, and the exemption for dwellings no longer applies. In most cases a fire safety certificate will be required before work begins, and a Disability Access Certificate usually follows where a fire safety certificate is needed. Applications in the county go through Cork County Council’s building control applications process, and it makes sense to lodge both together. This applies even where planning permission isn’t needed.
What to check before you start
Get advice on where your specific plan sits before committing to a design or signing with a builder or modular supplier. The same 40 square metres can fall into quite different categories depending on how it will be used. It’s also worth confirming the project qualifies for Class 3A in the first place. An existing shed, a small garden, or a condition on the original planning permission can all rule out the exemption, and in that case a full planning application is the route forward.
Don’t assume “exempt” means no professional input is needed. Someone still has to certify the design and the finished work, and it’s far easier to get these details right on paper than to fix them once the unit is built.
If the unit is for a parent with limited mobility, think about access from the outset. A granny flat won’t need a Disability Access Certificate, but it still has to meet the accessibility requirements of the building regulations. Level access and wider doorways are much simpler to design in now than to add later.
Getting the right answer early
If you’re planning a granny flat or thinking about converting your home into two units, it’s worth getting a clear answer on the building control and fire safety side before you commit to a design. BCE Consulting Engineers has secured more than 50 planning permissions and over 30 fire safety certificates for clients across Cork, and our engineers are members of Engineers Ireland. Get in touch and we’ll talk you through what’s involved before work starts.
With Cork County Council pushing new guidance on vacant and derelict properties this month, and thousands of empty homes scattered across the county, more people are seriously weighing up a fixer-upper. It’s an appealing idea. Character, space, and a grant to help with the bill.
But there’s one piece of paperwork that decides whether you get €50,000 or the full €70,000, and it starts with an engineer, not a builder’s quote.
A quick recap of the grant
We’ve covered the Vacant Property Refurbishment Grant in detail before, so here’s the short version. You can get up to €50,000 towards refurbishing a vacant property, or up to €70,000 if the property is also derelict. It applies to homes vacant for at least two years and built up to and including 2007. You apply through your local authority before any works start.
The derelict top-up is where most people get stuck
To unlock the extra €20,000 on top of the standard grant, your property needs to meet the derelict definition. That means it’s either already on the Derelict Sites Register, or it’s independently assessed as derelict.
That independent assessment is a structural report confirming the property is structurally unsound and dangerous. This is the part that needs an engineer, not a builder, not an estate agent, and not a grant officer.
It’s also not a rubber stamp. A proper structural assessment looks at things like a compromised roof structure, movement in the walls, or foundation problems. If a property is simply tired and outdated but structurally sound, it won’t qualify for the top-up, no matter how long it’s been empty. Knowing the difference before you apply saves a lot of wasted time.
With that much activity, applications that are well prepared from the start tend to move more smoothly. Getting a structural report done early, before you’ve fallen in love with a property or lined up a builder, gives you an honest read on what you’re actually taking on. It’s a lot easier to walk away from a property at survey stage than after you’ve committed.
What to do before you apply
Start with an independent structural survey. It supports your derelict top-up application and gives you a realistic picture of the scope of works involved, before you spend money on anything else.
Don’t assume vacancy alone means derelict. The two bands are assessed differently, and the paperwork differs accordingly. A property can be vacant for years without meeting the structural threshold for derelict status.
And budget with your eyes open. The grant is paid on completion and after inspection, not upfront, so you’ll need to manage cash flow through the works yourself.

House hunting in Cork right now often comes down to a choice. On one side, a bright, energy efficient new build with an A or B rating and a price tag to match. On the other, a characterful older home with a D or E rating and a much more tempting asking price. It’s easy to assume the older home just needs a bit of attic insulation and a new boiler to catch up. Often, that’s not quite the full story.
More often than not, a low BER on an older property is telling you something about the building itself, not just its heating bills. And that’s where a structural engineer’s eye can be just as useful as the energy assessor’s when you’re trying to work out what a home will really cost you.
What a BER rating actually tells you (and what it doesn’t)
A Building Energy Rating, or BER, measures how energy efficient a home is, on a scale from A to G. It’s a legal requirement for any home being sold or rented in Ireland, and it’s a useful starting point for comparing properties. BER certificates are issued only by SEAI registered assessors, and that’s not something BCE does or has any involvement in.
What a BER rating doesn’t tell you is the underlying condition of the property. It won’t tell you whether the walls, roof, or foundations are sound, or whether getting that home up to a decent standard is a straightforward insulation top-up or something more involved. Two homes with the same D rating can be in very different states of repair.
Why older Cork homes so often land on a low BER
A large share of Cork’s housing stock predates modern building regulations and insulation standards, particularly in older city neighbourhoods like Sunday’s Well, Montenotte, St Luke’s, and Blackrock, where you’ll find plenty of Victorian and Edwardian era homes still in daily use. A survey will often turn up a familiar list of culprits: solid stone or block walls with no cavity insulation, damp coming in somewhere, poor or missing roof insulation, draughty original windows, and heating systems well past their best.
The point worth taking on board here is that a low BER on an older home is rarely down to one simple fix. It’s usually a combination of structural and fabric issues working together, and it’s worth understanding which ones you’re actually dealing with before you commit to a price.
Why this matters for your budget as a buyer
A D or E rated home can look like a bargain next to a newer, higher rated one. But bringing a property up to a decent standard, insulation, ventilation, and sometimes structural work to deal with damp, can easily run to a five-figure sum once you add it all up.
Understanding what’s actually driving a low rating gives you something to work with. It puts you in a stronger position to negotiate, or at the very least to budget realistically, rather than being caught out six months after you’ve moved in.
Where a pre-purchase survey fits in
A structural survey doesn’t replace a BER assessment, and it’s not trying to. What it does is explain the physical condition sitting behind the number. Damp, gaps in insulation, the state of the roof, and any unauthorised alterations that could complicate future retrofit work are all things a survey picks up that a BER cert won’t flag.
If you’re weighing up an older home and the BER has you wondering what you’re really taking on, get the structural picture first. It tends to save a lot of guesswork later.
You’ve just picked up the keys, or you’re about to, and your snag list has come back with a page full of issues. A door that doesn’t sit right. Patchy paintwork. A window that won’t seal properly. It’s a stressful moment, especially when the whole process of buying a new build already feels like it’s taken every ounce of patience you have. Take a breath. Snags on a new build are normal, and in most cases, entirely manageable.
Here’s what’s reasonable to expect fixed, what your timeline actually looks like, and what your options are if the builder isn’t moving fast enough.
Why your snag list has more leverage than you think
Most buyers assume the real power sits with the builder once contracts are signed. In practice, you have more leverage at this stage than you might think, and it’s worth using it before the money changes hands, not after.
Your solicitor can hold back part of the closing balance until outstanding snags are resolved. This is a standard protection built into new build purchases in Ireland, and it exists precisely for situations like this. If your snag list has come back with a list of items that still need attention, this is the moment to raise it with your solicitor and use that leverage. Once you’ve handed over the full balance and moved in, your position weakens considerably. The builder has been paid, and getting outstanding work prioritised becomes a matter of goodwill rather than contractual obligation.
If you’re still mid transaction, this is worth flagging early. Your solicitor can advise on how best to structure this for your specific contract.
What’s reasonable to expect fixed
It helps to go in with realistic expectations rather than assuming a snag list means something has gone badly wrong. Cosmetic and functional issues are common on new builds and normally get addressed without much pushback from the builder. Think uneven paintwork, doors that haven’t been hung quite straight, or poor sealing around windows and doors. These are the bread and butter of any snag list, and a reasonable builder will fix them as a matter of course.
What you shouldn’t expect is a completely clean re-inspection. Some items will get fixed outright. Others might get explained to you as being within normal tolerance for construction work, which is sometimes a fair point and sometimes worth pushing back on. The goal isn’t perfection. It’s making sure the genuine issues get sorted and the reasonable exceptions are actually reasonable, not the builder trying to wriggle out of a fix.
The timeline you’re working with
Snagging generally needs to happen within about 14 days of the Completion Date, so there’s a real window here, not an open-ended one. That might sound tight when you’re also juggling removals, mortgage drawdown, and everything else that comes with moving, but it’s there for a reason. It gives you a defined period to raise issues while you still have some contractual weight behind you.
If you don’t get your snag list done within that window, you’re not necessarily out of options, but you lose some of the natural leverage that comes with an active, live process. This is exactly why booking your snag list inspection early matters. Don’t leave it to the last few days before completion. The earlier you get an independent set of eyes on the property, the more room you have to actually act on what comes back.
What your structural guarantee covers if something’s missed later
A snag list catches what’s visible right now. It’s not designed to catch problems that only show up months or years down the line, and that’s where your structural guarantee comes in as a backstop.
Most new builds in Ireland come with a tiered guarantee structure. Broadly speaking, you’ll typically have a shorter initial period that covers things like loss of deposit protection, a mid-length period that covers issues such as water ingress or latent defects that weren’t apparent at completion, and then a longer structural guarantee that runs for years and covers major structural elements of the home.
The exact terms vary depending on your specific guarantee provider, so it’s worth having your solicitor or the guarantee documentation on hand if something comes up later. The point to take from this is simple: your snag list is about what you can see and fix now, and your guarantee is what protects you if something you couldn’t have known about shows up after you’ve moved in.
If the builder pushes back or drags their feet
Most builders want to get snags sorted and move on, but it doesn’t always go smoothly. If you’re finding the response slow or half hearted, a few practical steps help.
Put your follow ups in writing. A dated email or letter setting out what was raised and when creates a clear record if things drag on. Once the builder says an item has been fixed, go back and re-inspect it rather than taking their word for it. If progress genuinely stalls, that’s the point to loop in your solicitor, who can advise on next steps given your specific contract.
If you’re not confident the fixes have actually resolved the issue, or you’d simply like an independent opinion before you sign off, it’s worth bringing in a second, impartial set of eyes rather than relying solely on the builder’s assurances.
