Single Storey Extension

A single-storey extension is a great way to add more space to the side or rear of your home, or even both. It is one of the most popular project types for existing dwellings that lack functionalities for your style and practical needs. Whether you need extra living space for your growing family or are looking for a new home design, extending your house is one of the best options to consider.
