What is a single storey extension?
A single storey extension adds ground-floor living space to your home in one level, whether that is across the back of the house, down the side, or wrapped around both. For the large detached and semi-detached houses typical of Four Oaks, it is usually the simplest way to gain a bigger kitchen or family room without altering the roofline or the character of the street.
Rear extension
Builds out into the garden, freeing up space for an open-plan kitchen and dining area.
Side-return extension
Makes use of the side passage found on many Four Oaks semis and detached homes.
Single-storey wraparound
Joins a rear and side-return extension together for a larger L-shaped room.
Homeowners in Four Oaks most often use the extra space for a family kitchen, a garden room, or a home office, while keeping the extension in keeping with the property's existing style.

Do I need planning permission for a single storey extension in Four Oaks?
Four Oaks falls within the City of Birmingham, so Birmingham City Council is the local planning authority, even though Sutton Coldfield has its own town council for local civic matters. Many single storey rear extensions still fall under permitted development, generally up to 4m deep for a detached house or 3m for other house types, or up to 6 to 8m under the Larger Home Extension scheme with a neighbour consultation. Four Oaks also has its own designated conservation area, separate from Sutton Coldfield's other conservation areas, which brings extra planning controls over demolition and alterations that affect the character of the area. We check your property against both the permitted development rules and any conservation area constraints before recommending a route, and handle any application on your behalf.
