When viewing potential properties, have you noticed large, round metal plates bolted to the exterior walls? These construction elements, known as pattress plates or structural wall ties, often raise questions for homebuyers. While they might initially cause concern, these features typically indicate responsible structural reinforcement rather than a problem.
What are those metal plates on building walls?
Looking around a selection of properties will allow you to compare and contrast different homes, but there will always be something that potentially raises a concern. One of those things might be the large, usually round metal plates bolted to the side of the building, typically at the same level and at regular intervals.
These construction items are known as pattress plates, and they come in all different shapes and sizes. The more ornate designs are intended to add to the beauty and interest of the building, offering something more pleasing to the eye than a simple plate and bolt.
The purpose of structural wall ties
How do they work?
The simple answer is that pattress plates increase the stability of the building by holding the
If left unmanaged, this weight will bear down and cause bowing in the walls, potentially leading to eventual collapse. The pattress plates and structural rods effectively bring the potential for bowing under control - think of it as putting a belt on when you've put on a bit of Christmas weight!
Should you be concerned when buying a property with wall ties?
Those of us who have gone through at least one home move can relate to the pressures and stress involved. But equally, it can be an exciting time as you plan what to do with the property you're considering.
One of the areas that may give you pause for thought is the stability and condition of the property. You might wonder whether you'd be taking on a money pit to get it up to scratch or if you're likely to be buying somewhere that needs very little work.
Building regulations and structural integrity
As with all structural techniques and materials, there are building regulations that must be followed and signed off. The use of pattress plates and the load distribution of the roof on the walls are naturally subject to these constraints.
So, while you might be concerned about the appearance of these plates on the external (and, in some cases, internal) walls, they are almost certainly an effective way of strengthening the structure, giving you much habitable pleasure in the future.
The importance of proper building survey
Nevertheless, it's always wise to commission a building survey from an experienced chartered surveyor. They will use their knowledge and tools to assess the structure and condition of the overall property, providing suitable advice on what, if any, remedial work needs to be carried out and the severity of any problems.
When it comes to pattress plates installed in the last couple of decades, your chartered surveyor may suggest that your conveyancing solicitor specifically check the archive of planning consents with the local authority. This can confirm that the wall ties have been fitted according to the building regulations of the time, since detailed physical checks might be too invasive to the structure.
Ensuring your new home is structurally sound
When buying your next property, you'll want to ensure that it is structurally sound and fit for habitation, whether it's built in the traditional way with bricks and mortar or uses newer architectural ideas and different materials.
The progression from viewing property particulars to making an accepted offer opens up different avenues and thoughts. You'll consider what's acceptable to you and what compromises you might have to make for features you really want - all adding up to a fluid but energizing step in the process.
