Structural and Partition Walls
Are you planning a barn conversion? Perhaps you want to open up your home to create modern living spaces. Maybe you need to divide rooms to suit your family’s changing needs. Whatever your project, structural and partition walls form the heart of transforming properties throughout Neath Port Talbot and Swansea.
At Welsh Stonework, we bring over 50 years of combined experience to every project. Additionally, we handle everything from load-bearing wall installations to interior partitions. We know that our work—much of it hidden once complete—keeps your home safe, stable and functional.
Expert Structural Alterations Across South Wales

Open-plan living has become hugely popular across Neath, Swansea and the surrounding valleys. Homeowners want to unite kitchens and dining areas. Similarly, they want to knock through walls to expand living rooms. However, these changes need careful assessment and expert work.
We manage every aspect of your project. First, we carry out initial surveys. Then, we handle building regulation compliance. Finally, we install steel beams, lintels and supporting structures.
Our team knows the traditional building methods found throughout South Wales properties. For instance, we work regularly with Victorian terraces in Port Talbot and stone cottages in the Swansea Valley. Furthermore, we understand how builders constructed these properties. As a result, we can alter them safely whilst preserving their character.
Load-Bearing Walls and Internal Partitions
Not all walls serve the same purpose. Load-bearing walls support floors, roofs and upper storeys. In contrast, partition walls simply divide internal space. Understanding this difference is critical to maintaining your property’s safety.
We build new load-bearing walls using traditional stone, brick or blockwork. Moreover, we ensure proper foundations and structural ties to existing buildings. For internal partitions, we offer several options. These include blockwork, timber stud framing and other materials. Consequently, you can choose based on your needs for soundproofing, fire resistance and room use.
Barn Conversions and Period Property Alterations
The Neath Port Talbot and Swansea areas feature many character properties. Old barns, stables, mills and farmhouses await transformation into beautiful homes. Nevertheless, these conversions present unique challenges. They need experience, sensitivity and appreciation for traditional methods.
We create the internal structure needed to convert these spaces. At the same time, we respect their agricultural heritage. For example, we install new partition walls to create bedrooms and bathrooms. Alternatively, we carefully remove sections of stonework to create doorways and windows. Throughout the process, we work with both traditional Welsh Blue Pennant Stone and modern materials. This approach achieves the perfect balance between old and new.
Building Regulation Compliance and Structural Calculations
Any structural alteration must comply with current building regulations. Therefore, we work closely with structural engineers and building control officers. This ensures all work meets the required standards.
Our service covers several key areas. Firstly, we obtain structural calculations for beam installations. Secondly, we ensure proper fire resistance between dwellings. Finally, we meet current thermal standards for new walls.

We manage the entire regulatory process from start to finish. Initially, we begin with your consultation. Subsequently, we guide you through to final inspection and certification. As a result, you have peace of mind that your structural work meets the highest legal and safety standards.

We work with a wide range of building materials suited to both traditional and modern construction:
