Common Projects: Loft Conversions

Loft conversion regulations for a property that is no more than two storeys high is likely to be less extensive than those required for alterations to an apartment, maisonettes or houses over two storeys high. Alterations to the loft space may be to enhance storage facilities or to increase the living space of the building. Building Regulations may apply depending on the work planned.

The regulations would ensure that

  • the structural strength of the new floor is sufficient
  • the stability of the structure (including the existing roof) is not endangered
  • safe escape from fire safely designed stairs to the new floor
  • reasonable sound insulation between the conversion and the rooms below.

Boarding-Out for Storage

In most homes, the existing timber joists that form the "floor" of the loft space ( i.e. the ceiling of the rooms below) will not have been designed to support a significant weight (known as "load"). The joists tie the pitched members of the roof together to prevent them spreading and support the ceiling lining of the rooms below.

An excessive additional load from storage may mean that the joists are loaded beyond their design capacity. Building Regulations may be required if flooring boards are to be laid over the existing joists. The local Building Control Body will advise whether this is required.

Additional Living Space

Creating additional living space in the loft may require significant alterations. These could have an adverse impact on the building and its occupants and must be created in accordance with legislation.
