What is a modular house extension?

A modular house extension is an extension manufactured off-site in a factory-controlled environment before being delivered and installed on your property. This modern construction method can reduce build times while maintaining high levels of quality and precision.

Are modular house extensions cheaper than traditional extensions?

The cost of a modular house extension depends on its size, specification, and complexity. However, modular construction can often provide greater cost certainty, reduced waste, and shorter construction programmes compared to traditional building methods.

Do modular house extensions require planning permission?

Planning requirements depend on the size, design, and location of the extension. Some projects may fall under permitted development rights, while others require planning approval. Each project should be assessed individually.
