Extensions & Renovations Cardiff

building and roofing contractor based in CardiffCommiting to an extension on your property is a big decision and a project that needs to be executed by professionals.

Whether you are planning a single storey extension, rear wall extension, side extension or a double storey extension there are plenty of options. But where do you start? Building work on an existing house requires many elements that need to be addressed.

Cardiff Renovations

Specialists in domestic and commercial properties in Cardiff and the wider area, our expertise is vast. From complete renovations to expanding existing areas and installing new staircases and door frames, to name a few. The benefits of renovations or an extension are wide. Not only are you improving the overall look of your property, but increasing the overall value of the building.

From your first call to Peter E Smith Builders we will provide a free quotation and inspect the property in question. Then we will present a bespoke design to suit your needs. If it’s home improvements or a large scale extension you need, we will provide a complete service from start to finish.

Local Planning Authority

The first hurdle with any house extension or development on an existing building is the local planning authority. We will take care of planning permission on all building and maintenance works including listed buildings. Planning permission is also required on conservation areas to enhance and improve a building.

The Party Wall Act 1996 has been hitting headlines recently with grand-scale extensions causing problems for neighbours and boundary walls. With our 30 years of experience we are accustomed with the challenges that can occur and how to handle them accordingly.  


Once the permitted development has been approved by the local authorities it’s time to get to work. We will supply all materials desired for the project and pass all good ideas by you for approval.

From digging the foundations to carrying out the structural engineering process and applying the final layer of paint, you can rely on an efficient service from Peter E Smith Builders. Plus, we’ll discuss the best possible roof, deciding between a flat or pitched roof.

Disruption During Development
