What is the recommended height for a kitchen worktop?

The coordinating height for kitchen worktops and sinks is generally 900 mm (Table 1).

What is the standard coordinating size for a single bed?

A common coordinating size for a single bed is 900 mm x 1900 mm (Annex B).

What is the minimum clearance recommended in front of a water closet (WC)?

A clear space of at least 750 mm should be provided in front of the WC pan (Annex A).

What is the purpose of this standard?

To provide a rationalized and coordinated system of dimensions for furniture, fixtures, and equipment to ensure they fit within buildings designed using modular coordination principles.

This standard (Part 4) provides recommendations for dimensional coordination of services and drainage systems like plumbing, electrical, and HVAC within buildings. It establishes a system of preferred dimensions, zones, and routes based on a 100 mm basic module to ensure compatibility and facilitate efficient installation, particularly in prefabricated construction.

Practical Notes

Primarily used by architects and interior designers during the space planning and layout design phase.

Following these dimensional guidelines helps ensure ergonomic clearances and functional arrangements, preventing common layout mistakes.

The code is crucial for standardizing component sizes, which facilitates prefabrication and efficient use of building information models (BIM).
