RICS Level 3 Building Survey in Rhiwbina

The housing stock in Rhiwbina presents unique challenges that make a detailed Level 3 survey essential. The area features properties ranging from the early 20th-century Garden Village houses built from 1912 onwards, through to interwar homes in the Brooklands estate from the late 1920s and 1930s, and newer constructions. Each period brings its own typical defects and maintenance requirements that our surveyors know intimately. We have inspected properties across all these age ranges and understand the specific construction methods used by builders like those who developed the original Garden Village under architects such as A.H. Mottram and H. Avray Tipping.

Rhiwbina Garden Village, designated as a Conservation Area in 1976, contains numerous listed buildings including Briwnant Farmhouse, Hafod Lwyd, and properties along Lon-y-Dail and Lon Isa. These heritage properties often have specific requirements regarding alterations and renovations, and a Level 3 survey from our team will identify any issues that might affect your plans or trigger heritage considerations. We understand the balance between preserving original features like the distinctive Buckingham Green windows that characterise the Garden Village and identifying defects that need attention.

Many properties in the Rhiwbina Hill area were constructed between 1800 and 1911, making them over 110 years old. Welsh housing is among the oldest in the UK, with over a quarter of homes built before 1919. These older properties frequently have solid wall construction, traditional lime-based mortars, and may have been subject to numerous alterations over the decades - all factors our surveyors examine in detail. The age of these properties means that original features may be deteriorating, and previous owners' repairs may not meet modern standards.

Cardiff's geology presents particular challenges, with properties often built on alluvial clay that carries a risk of subsidence due to shrink-swell movement. This is particularly relevant for any property with trees or vegetation nearby, as clay soils expand and contract significantly with moisture changes. Our surveyors assess the signs of any such movement and advise on necessary investigations. Properties in Rhiwbina are not immune to these ground conditions, and we have identified subsidence issues in several properties where trees have been planted close to the building footprint.

• Garden Village period properties (1912-1923)
• Rhiwbina Hill period houses (pre-1911)
• Brooklands estate 1930s homes
• Modern properties near Plasdwr development
• Listed buildings in conservation areas

Cardiff faces the highest flood risk of any local authority in Britain, with around 33,000 properties facing flooding risk by 2050. While Rhiwbina is situated north of the city centre and away from the main River Taff corridor, surface water flooding remains a concern across the Cardiff area. Our surveyors check for signs of previous flood damage, the effectiveness of existing damp-proofing, and any repairs that may have been carried out following flood events. We specifically look for water staining, tide marks, and warped flooring that may indicate past flooding.

The city sits where the River Taff and River Ely meet the Severn Estuary, creating risks from tidal surges, river flooding, and surface water runoff. Properties in lower-lying areas of Rhiwbina may be susceptible to surface water accumulation, particularly during heavy rainfall events. A Level 3 survey will identify any evidence of past water ingress and assess the adequacy of drainage around the property. The Cardiff Bay Barrage helps manage tidal risk, but surface water flooding during heavy storms remains a concern throughout the area.

Flood damage remediation can cost upwards of £30,000, making it essential to understand a property's flood history before purchasing. Our surveyors look for tell-tale signs including tide marks, water staining, warped floorboards, and damaged plasterwork. We also check the condition of any existing flood mitigation measures and advise on the adequacy of property drainage systems. If the property has a history of flooding, we will recommend appropriate investigations and may suggest a Flood Risk Assessment.

Our experience surveying properties across Rhiwbina has identified several recurring issues that buyers should be aware of. Many older properties, particularly those built before modern building regulations were introduced, may have been subject to alterations and extensions that were not properly approved. This can affect everything from loft conversions to kitchen extensions and may require retrospective building regulation approval. We have found that many Garden Village properties have had modifications over the decades that may not meet current standards.

Damp is a common finding in period properties, especially those with solid walls rather than cavity wall construction. While some dampness is normal in older properties, our surveyors assess whether it indicates a serious problem requiring remediation or simply reflects the age and construction type of the building. We check the condition of existing damp-proof courses and recommend repairs or improvements where necessary. The original DPCs installed in Garden Village houses were groundbreaking for their time but are now approaching a century old and may be failing.

The clay soil underlying much of Cardiff can cause subsidence issues, particularly for properties with trees planted close to the building. Signs of past movement include cracks in walls, doors and windows that stick, and uneven floors. Our surveyors carefully examine the property for these signs and may recommend a specialist structural engineer's report if significant movement is suspected. Underpinning work to address subsidence can cost between £12,000 and £20,000 for a terrace property, making early identification essential.

Roof condition is another frequent concern, particularly for period properties with original roof coverings that may be reaching the end of their lifespan. We inspect all accessible roof spaces, check the condition of tiles or slates, examine flashing around chimneys, and assess the condition of roof timbers for any signs of rot or insect damage. For properties in conservation areas, we also consider whether any roof repairs or replacements will need to match the original materials to maintain the property's heritage value.
