RICS Level 3 Building Survey Ogbourne St. Andrew

A RICS Level 3 Survey is our most detailed inspection, and for much of the housing stock in Ogbourne St. Andrew it is the right standard to use. We check all accessible parts of the property, from the roof space and sub-floor areas through to walls and foundations. Rather than stopping at a basic overview, we look closely at structural integrity, including timber beams, load-bearing walls and the overall condition of the building fabric. We also photograph significant defects and add clear annotations, so the issues we identify are easy to follow.

In Ogbourne St. Andrew, we shape the survey around the building methods found in the village itself. That means checking timber-framed structures with brick nogging, looking for movement or decay in sarsen and flint stone walls, and assessing thatched roofs, which remain a distinctive local feature. Many cottages on the main street and at Rockley use traditional wattle and daub infill or brick nogging between timber frames, and our surveyors know the warning signs these older forms of construction can present. We also inspect details such as stone quoins and ashlar dressings, seen on properties including Ogbourne Maizey Manor.

Damp is another major part of the survey, especially here, where some properties have a long history of spring water emerging through foundations. The River Og is a winterbourne, so it only flows seasonally, and homes on its flood plain or close to spring lines have seen water ingress in the past. We look for evidence of earlier flooding, review present drainage arrangements, and consider any remedial work that may already be in place. This is particularly useful in the valley ground between Ogbourne St. Andrew and Ogbourne Maizey, where the valley narrows and spring emergence is most often found.

After the inspection, we send a detailed report setting out any defects, the likely cause of each one, and our recommendations for remedial work. We use a traffic light rating system, which makes it easier to see what needs urgent attention and what can simply be kept under review. In a place like Ogbourne St. Andrew, where historic construction methods meet tricky local geology, that level of explanation matters.

Some of the problems we see in Ogbourne St. Andrew are very specific to the area. The underlying geology is mainly chalk, but in the higher ground near Barbury Castle there are deposits of clay with flints, and that can lead to shrink-swell movement where properties sit on clay subsoil. It is most relevant in the north-eastern parts of the parish, where those clay deposits are more common. Our surveyors know how to spot the quieter signs of movement, such as particular cracking patterns in walls or doors that have started sticking or no longer close properly, which may point to ongoing subsidence.

Spring water flooding has long been a distinctive issue here. Because the River Og is a winterbourne, and because its valley is at its narrowest between Ogbourne St. Andrew and Ogbourne Maizey, properties on the flood plain or close to spring lines have historically been vulnerable to water ingress. The river course at Ogbourne Maizey was straightened in the mid-20th century to reduce flooding, but spring water still rises through the foundations of some older houses and has even flooded the cellars of Rockley Manor. Historical records mention cottages standing in 2-3 inches of spring water in the late 1960s, and flash flooding from rising springs was a recognised winter problem in the mid-20th century. We check for signs of that history, assess drainage as it stands now, and review any remedial measures already installed.

Ogbourne St. Andrew has a strong architectural identity, and many properties are listed or affected by conservation considerations. St Andrew's Church, with 12th-century origins and a Grade I listing, is the most prominent landmark, while many cottages and farmhouses along the main street are Grade II listed. Our Level 3 Survey explains the listed building implications where relevant and sets out the maintenance demands and restrictions that can come with older homes. We also consider traditional materials such as thatch, sarsen and flint, and comment on repair approaches that respect historic character. That matters for buildings like The Thatch, a 17th-century listed thatched cottage, and Old Cottage, which dates from the late 16th century.

Across the village, timber-framed construction appears again and again, particularly in 17th-century cottages with exposed frames and brick nogging. It is an attractive and historically appropriate method, but it can bring risks of timber decay, structural movement and failure in the infill if upkeep has slipped. We inspect every accessible timber element closely for beetle activity, rot and signs of previous repair that may suggest continuing movement. Rockley Farm, derelict in 1980 and later restored, is a good example of how quickly an older timber-framed building can deteriorate without the right maintenance, and our survey helps put similar properties into context before you buy.

Book a RICS Level 3 Survey with us and you get the benefit of detailed local knowledge, not just a standard inspection. Our surveyors have looked at hundreds of properties in this part of Wiltshire, including thatched cottages, Georgian farmhouses and newer conversions. We understand how the chalk uplands and the clay-with-flints deposits affect buildings here, and that is not always the same as elsewhere in the country. It means we know where problems are likely to show themselves, and where a less experienced surveyor might miss them.

The setting matters too. Ogbourne St. Andrew sits on The Ridgeway, an ancient highway with origins in prehistoric times, and many properties occupy sites with very long histories behind them. We factor that into how we read the building. The local racehorse training industry also shapes the property mix, so houses here may come with stabling, gallops or agricultural buildings that need a more specialist eye. We are used to dealing with those buildings, and we reflect that in our advice.

We want the report to be useful, not just lengthy. So instead of filling pages with generic comments that could apply anywhere, we write in terms that suit Ogbourne St. Andrew, from the condition of sarsen stone walls to the practical issues involved in maintaining thatched roofs in this climate. By the time you receive it, you should have a clear view of the property's condition and of any issues likely to affect value or future spending.
