Plan and Layout


The plan and internal layout of houses should provide a high standard of living accommodation for their occupants in terms of size, layout and daylight. Rooms should provide adequate space for their intended purpose and be capable of adaptation to support the changing needs of their occupants.

Features of housing plan and internal layout

  • Internal layout must consider the visual impact on the external appearance of the building.
  • Multiple living spaces for larger properties
  • Cross ventilation for through breezes across the house
  • Dual aspect allowing maximum light entering from both sides of house
  • Ample storage spaces
  • Habitable rooms orientated on elevation with maximum daylight
  • Consider the flexibility of internal spaces with user


Nationally Described Space Standards

The calculator has adapted from from the Technical housing standards – nationally described space standard (March 2015) by the Department for Communities and Local Government

Internal living environment


A modern interpretation of the classic ‘Trafford twin’ achieves a number of objectives for internal layout including great natural daylight, well separated habitable rooms and lots of cross ventilation

The image shows the interior layout of a house with a generous bay window letting in daylight, a through breeze for ventilation and a seperated habitable room from neighbour. This image is illustrative only to demonstrate the principle of the code

Princples of living environments

The diagram shows a through breeze for ventilation.This image is illustrative only to demonstrate the principle of the code

Cross ventilation; dual aspect windows allow natural breezes through the house

Diagram shows how noise can be mitigated by separating habitable rooms between neighbours. This image is illustrative only to demonstrate the principle of the code

Noise mitigation; habitable rooms are separated to avoid excessive noise transmittance

The diagram shows how bay windows can allow large amounts of natural light. This image is illustrative only to demonstrate the principle of the code

Natural Daylight; habitable rooms face south with large windows for daylight
