What's the minimum width of a corridor?

Question

What's the narrowest a corridor can be in your house? Our bathroom is currently off a bedroom, so building a corridor would make it more accessible. But we're not sure if we can squeeze it in.

Dave · Accepted Answer

minimum width for uk domestic corridors are 900mm for able bodied persons and 1100mm for accessible persons access ie wheelchair/walking frame

Patrick · Answer

Standard corridor width should allow for 2 persons to pass ideally 80 cm

Peter · Answer

Hi , 
36"  (91.44cm)  is recommended to comply with ADA requirements. 
This complys for a single standard wheelchair, so we use this as a good guideline .

In London, the minimum width requirement for a corridor within a house can vary depending on the specific building regulations and local authority guidelines. However, there are some general guidelines to consider:

Building Regulations: Building regulations in the UK, including those in London, provide standards for the construction and alteration of buildings. These regulations often include requirements for minimum widths of corridors and passageways to ensure safe and accessible circulation. It's essential to consult with your local authority or a building control body to determine the specific regulations applicable to your area.

Accessibility Considerations: If your goal is to create a more accessible route to the bathroom, you should also consider the requirements for wheelchair accessibility. The minimum width for wheelchair access is typically wider than the minimum width for a standard corridor. Accessible routes often require a width of at least 900mm to accommodate wheelchair users comfortably.

Practicality and Functionality: Apart from the minimum requirements, it's important to consider the practicality and functionality of the proposed corridor. A narrow corridor may limit movement, create a cramped feeling, or make it difficult to carry items or furniture. It's advisable to aim for a width that provides sufficient space for easy passage and usability.

To determine the feasibility of adding a corridor to your house and ensure compliance with regulations, it's recommended to consult with an architect, architectural technician, or a building control professional. They can assess your specific situation, consider the existing layout, and provide guidance on the best approach to achieve your goals while meeting the necessary requirements.

Hi.

Well a standard door is 765mm so I guess as an max min I would make it 1000mm.
It really depends in the amount of traffic the corridor will take.
Maybe if you need to go down to 900mm but 1100mm/1200mm would be spot on

1 metre to 1.5metre all depends on size of your house

Michael · Answer

generally speaking 35 inches is the minimum width you can have a corridor.

Steven · Answer

Normally the width of your door, around about 900mm to 1000mm should be enough.

Eric · Answer

Building Regulations require a corridor width to be a minimum of 900mm. At 'pinch points', for example where there is a radiator, this can be reduced to 750mm. If you would like to make the home more accessible to all ages and abilities, aim to exceed the measurements given above

Michael · Answer

You should really allow 1m min width any smaller than you would walk down it side ways
