Building the perfect staircase for your home involves more than just choosing the right materials and a design that complements your interior. It's about ensuring safety, functionality, and compliance with the UK Building Regulations Part K. At Discount DIY, we're here to guide you through the maze of regulations to ensure your staircase is not only aesthetically pleasing but also meets all the necessary safety standards.


Staircase Design and Compliance: A Closer Look at Building Regulations Part K

Stair Pitch, Rise, and Going: A critical aspect of staircase design is the relationship between the rise (the vertical part of the step) and the going (the horizontal part). For a staircase to be comfortable and safe, these dimensions need to be consistent. According to UK Building Regulations Part K, the rise must be between 150mm and 220mm, and the going should be between 223mm and 320mm. This consistency is crucial for preventing missteps and falls, as we naturally expect each step to be the same.

Regulation Pitch of the Stairs: The pitch, or steepness, of a staircase, is another area regulated for safety. A maximum pitch of 42 degrees is generally enforced to ensure staircases are not too steep, making them difficult or unsafe to navigate. Exceptions can be made under certain conditions, such as in loft conversions, provided the design meets other safety criteria.

The Rule of 18: A handy guideline for balancing the rise and going is the 'Rule of 18'. Ideally, the sum of the rise and going should be around 18 inches (approximately 457mm). This rule helps create stairs that feel natural and comfortable to use.

Construction Considerations for Domestic Staircases: Whether you're opting for open or closed riser stairs, safety and comfort should guide your design. Open riser stairs, for instance, should not allow a 10cm sphere to pass through the gap, ensuring safety for small children. Additionally, the nosing (the edge of the tread that protrudes over the step below) should ideally be around 16mm to enhance comfort and safety while ascending or descending.

Width Regulations and Headroom: While there's no minimum width for staircases in domestic settings, ensuring they are comfortably usable is crucial. For wider staircases, regulations require handrails at intervals of 2000mm. Headroom is another important consideration, with a minimum of 2m required above the staircase to prevent accidents and ensure comfortable passage.

Staircase Handrails and Landings: Handrails must be provided on one side for stairs less than 1m wide and on both sides for wider stairs, with a height requirement of 900mm to 1000mm from the pitch line. Landings are essential for safety, requiring at least 400mm of clear space in front of the top and bottom steps and must be wider than the staircase itself for safety and accessibility.

Navigating Stairs That Turn or Change Direction: Incorporating turns or landings in your staircase design can save space and add visual interest. For stairs with kite winders, the combination of the rise and going needs to adhere to specific dimensions to ensure a safe and comfortable transition.
