HS2 Standards

Internal space standards for new development

All proposals which result in new living space should adhere to the London Plan internal space standards. Applicants are encouraged to view these as a minimum and exceed these standards where possible.

Notes

  • * Where a one person dwelling has a shower room instead of a bathroom, the floor area may be reduced from 39m2 to 37m2, as shown bracketed.
  • The Gross Internal Area of a dwelling is defined as the total floor space measured between the internal faces of perimeter walls1 that enclose a dwelling. This includes partitions, structural elements, cupboards, ducts, flights of stairs and voids above stairs. GIA should be measured and denoted in square metres (m2).
  • The nationally described space standard sets a minimum ceiling height of 2.3 meters for at least 75% of the gross internal area of the dwelling. To address the unique heat island effect of London and the distinct density and flatted nature of most of its residential development, a minimum ceiling height of 2.5m for at least 75% of the gross internal area is strongly encouraged so that new housing is of adequate quality, especially in terms of light, ventilation and sense of space.
  • The Gross Internal Areas in this standard will not be adequate for wheelchair housing (Category 3 homes in Part M of the Building Regulations) where additional internal area is required (or may be in the case of Category 2 homes) to accommodate increased circulation and functionality to meet the needs of wheelchair households.

Aspect

North facing (i.e. where the orientation is less than 50 degrees either side of north) should be avoided wherever possible.
