Plasdwr Garden City has brought five major housebuilders to CF15 simultaneously. Our snagging inspectors find what they leave behind.








CF15 is experiencing the most significant housebuilding period in Cardiff's history. Plasdwr Garden City - a 900-acre, 7,000-home development spanning Radyr, Llanilltern and Creigiau - has Barratt, Redrow, Bellway, Persimmon, Charles Church and Edenstone all building simultaneously across multiple parcels. When that many homes are being completed under the same deadlines, finishing standards vary. Our inspectors have caught missing cavity wall insulation, incorrect roof tile fixings, incomplete drainage connections and dozens of minor defects on new builds across the CF15 area.
With Redrow's Heritage Collection at Maes yr Haf priced from £486,000 to £628,000, and Charles Church's executive detached homes at Glan y Coed reaching £589,995, a snagging survey at less than 0.1% of the property value is a straightforward decision. Our inspectors work to NHBC and industry standards, producing a written report your solicitor can use to require remedial works before legal completion.

New Build Buyers Reporting Snags
HBF National Survey, March 2025
CF15 lies at the southern margin of the South Wales Coalfield. Pentyrch has documented ironworking and coalmining dating to the 1560s, and shallow historic workings may extend under parts of the CF15 area. The Mining Remediation Authority recommends a CON29M coal mining search for all properties in Development High Risk Areas - and much of CF15 falls within this designation. Our snagging survey does not replace a structural or mining search, but our inspectors flag signs of differential settlement, cracking patterns and drainage issues that may warrant further investigation.
Our inspectors have reviewed properties across the Plasdwr development and at Persimmon's Parish at Llanilltern Village. The defects most commonly found on CF15 new builds fall into predictable categories - predictable because they appear on large-volume sites regardless of the developer's brand.
Under NHBC Buildmark warranty, your housebuilder is obliged to fix defects in the first two years. Our written report gives you a documented schedule that you and your solicitor can use to hold them to that obligation.

Estimated from StreetCheck postcode sample data across CF15 8 and CF15 9 sectors. CF15 is among the most detached-heavy postcode districts in Wales, reflecting its affluent suburban and rural character.
Not every buyer in CF15 is purchasing a Plasdwr new build. Radyr village contains a significant proportion of pre-1919 housing - period houses on Heol Isaf and Station Road built from Pennant Sandstone (the blue-grey Coal Measures stone characteristic of Victorian Cardiff) with some use of Radyr Stone, the local Triassic breccia quarried between 1850 and 1910. This same stone was used in Llandaff Cathedral and Brunel's Taff Vale Railway Bridge.
These properties require different expertise. Pennant Sandstone walls were built with lime mortar, which is breathable and flexible. Re-pointing with modern cement mortar - a common mistake - causes moisture to become trapped in the wall, leading to internal damp and stone spalling. Our inspectors assess pointing condition, check for inappropriate cement repair on period stonework, and look for damp patterns consistent with failed mortar joints.
Welsh slate roofs on older Radyr properties also need specific attention. Original slates can last 100+ years, but nail fatigue ('nail sickness') develops as iron fixing nails corrode, causing slates to slip. Our inspection covers slate condition, ridge and hip tile pointing, and chimney flashing condition - areas frequently missed on a standard vendor's survey.
Natural Resources Wales maintains a Flood Warning Area for River Taff at Radyr Court Road (reference 103FWF197115). During Storm Dennis in February 2020, the Taff at Upper Boat reached a record 5.324 metres - 80cm above all previous records. Storm Bert in November 2024 reached 5.07 metres, the second highest ever recorded. 438 properties flooded across the Taff catchment in that event alone. New build buyers on the lower-lying parts of the Plasdwr site should check their specific plot's flood zone designation via the Natural Resources Wales Flood Risk Assessment Wales map. Our snagging survey includes assessment of drainage falls, rainwater pipe outlets and surface water management on individual plots.
Creigiau expanded rapidly through two estate-building waves: the mid-1970s, and again through the 1980s. These homes - red brick cavity wall construction with concrete tile roofs - are now 40-50 years old and reaching the age when building fabric issues become active. Our inspectors regularly find the following on 1970s and 1980s stock in areas like Creigiau:

Enter your CF15 address and property type. Our pricing is fixed - no hourly rates, no hidden extras. Most CF15 new builds are quoted within two minutes.
Our inspectors cover the whole CF15 area including Radyr, Creigiau, Pentyrch and Tongwynlais. We schedule around your completion date and can often inspect within 48-72 hours of booking.
We carry out a systematic inspection of all accessible areas - roof void, all rooms, external elevations, drainage, services and garden. A typical CF15 new build takes 2.5-4 hours depending on size.
Our report identifies all defects, categorised by severity. Each item is photographed and clearly described so your builder's site manager knows exactly what needs fixing - and your solicitor has documentation if they dispute it.
Prices are guide rates. Final quote confirmed at booking. Re-inspection visits from £150. All prices include VAT.
Our snagging surveys in CF15 start from £295 for smaller properties and range up to around £450 for larger detached homes like those at Glan y Coed or Redrow's larger Heritage Collection types. The CF15 area sits in the mid-range nationally - not the premium rates of central London, but not the very lowest either, reflecting the area's mix of high-value new builds. We give you a fixed price at the time of booking with no extras.
Yes, and this is the ideal time. Your contract should give you the right to have an independent inspector attend the property before legal completion, and we recommend doing so. Carrying out the inspection before you complete gives you the strongest possible position - you can require your solicitor to hold back funds or delay completion until agreed defects are addressed. Once you have completed and moved in, your rights still exist under the NHBC Buildmark warranty, but the practical leverage is much weaker. If your developer is refusing access, contact us and we can advise on how to proceed.
Most CF15 new builds take between 2.5 and 4 hours to inspect thoroughly. A Barratt 3-bed at Afon Las or a Persimmon 3-bed at The Parish would typically take around 2.5-3 hours. A larger Redrow Heritage Collection 4 or 5-bed, or a Charles Church executive detached at Glan y Coed, takes 3.5-4 hours given the additional roof space, larger garden areas, and more complex heating and ventilation systems. We do not rush inspections - every accessible area is checked.
Our snagging inspections are designed specifically for new builds, where the scope is defects arising from recent construction. For older properties in Radyr village - especially the Victorian and Edwardian stone houses - a RICS Level 2 or Level 3 survey is more appropriate. These provide an assessment of building fabric condition, including the Pennant Sandstone walls, Welsh slate roofs, chimney conditions and any evidence of historical subsidence or damp. We offer both services: book a snagging survey for your new build, or request a quote for a RICS survey on an older Radyr or Creigiau property.
Yes, this is worth taking seriously. CF15 sits at the southern fringe of the South Wales Coalfield, and parts of the area - particularly around Pentyrch and Tongwynlais - have documented ironworking and coalmining history from the 16th century onwards. The Mining Remediation Authority publishes a map viewer where you can check your specific postcode's coal mining risk designation. Your solicitor should order a CON29M coal mining search as part of the conveyancing process on any CF15 property. Our snagging inspection is not a structural or mining survey, but our inspectors note cracking patterns or settlement evidence that may warrant further investigation.
The River Taff defines the eastern boundary of Radyr and Morganstown, and Natural Resources Wales maintains an active Flood Warning Area for River Taff at Radyr Court Road. Storm Dennis in February 2020 and Storm Bert in November 2024 both produced near-record Taff flood levels. New build buyers on lower-lying plots within the Plasdwr development should verify their specific plot's flood zone designation via the NRW Flood Risk Assessment Wales interactive map before exchanging contracts. Residents near Capel Llanilltern raised drainage concerns during The Parish planning process, and Cardiff Council required specific drainage remediation works. Our inspection checks surface water drainage, rainwater outlet falls and any signs of standing water on the plot.
As of 2025-2026, the following housebuilders are active in CF15 and the immediately adjacent areas: Barratt Homes (Afon Las at Plasdwr, from £369,995), Redrow Homes (Maes yr Haf at Plasdwr, Heritage Collection from £486,000), Bellway Homes (Rhiwlas at Plasdwr), Persimmon Homes (The Parish at Llanilltern Village, from £334,995), Charles Church - Persimmon's premium brand (Glan y Coed, from £499,995), and Edenstone with Pobl Group (Parcel 2C at Plasdwr, 181 homes in planning as of December 2024). Our inspectors have experience across all of these builders' standard construction methods and the defects most commonly associated with each.
We aim to deliver your completed written report within 24 hours of the inspection. If you have a solicitor-imposed deadline or a specific completion date, let us know at the time of booking and we will prioritise accordingly. The report includes photographs of every defect, a written description, and a severity category. We recommend sending the report to your developer's site manager and your solicitor simultaneously.
