What is a Single Storey Extension?
A single storey extension is a ground floor addition to your home — typically to the rear or side — that creates additional living space without building upwards. It is one of the most popular home improvements in Edinburgh, adding kitchen-dining, living room, utility, or bedroom space to thousands of Edinburgh homes each year.
Single storey extensions can be rear extensions, side extensions, wraparound extensions, or a combination. They typically feature large glazed bi-fold or sliding doors, roof lanterns, or skylights to flood the new space with natural light.
Costs for single storey extensions in Edinburgh range from around £28,000 for a compact addition to over £95,000 for a large, high-specification project. We provide fixed-price quotes after a free site visit — call us on 07890 903645.
