What is a single storey extension?
A single storey extension is a single-level addition to your home, built at the rear, to the side, or wrapped around the side and rear. It is one of the most popular ways to add usable ground-floor space without the cost or disruption of building upwards.
Rear extension
Projects into the back garden, ideal for a larger kitchen-diner.
Side-return extension
Fills in the narrow alley down the side of the house.
Single-storey wraparound
Combines a rear and side-return into one L-shaped space.
Typical uses include a bigger kitchen or dining area, extra living space, or a home office or playroom.
