New Side Extension

Side extensions are those which are built to the side of the property. This is a great option if you do not want to lose your garden space but have a semi-detached or detached property which allows for an extension to the side of the property.

All side extensions will require planning permission.

The below points must be met when building a side extension to your existing property:

  • It cannot exceed four metres in height.
  • It can only be a single storey.
  • Can only be up-to half the width of the original house
