Where Do Stairs Go in a Loft Conversion? Find Out Here!

When it comes to transforming your loft into a functional living space, one of the biggest questions is Where Do Stairs Go in a Loft Conversion?

In this blog, we’re unraveling the secrets of staircase placement in loft conversions.

The layout of an existing property often dictates where a staircase can be placed in a loft conversion. However, with careful planning and design, it’s possible to create a functional and visually appealing staircase.

Sometimes, finding the right place for a loft staircase isn’t obvious. It requires thoughtful consideration. Clients may initially suggest using a cupboard for the staircase, but it’s important to remember that stairs often need more space than a cupboard can provide, and they might not fit.

Staircases can be one of the more challenging aspects of a loft conversion.

When planning loft access, the primary concern is headroom. There should be at least 2.0 meters of headroom on the stairs, at the bottom, and at the top. Additionally, it’s often best to position the stair exit near the middle of the room, ideally below the centerline of the roof, to optimize space usage.

A good rule of thumb is to locate the stairs to access the attic at the highest point of the loft for practicality and efficiency.

Here are some key factors to consider:

Building Regulations – Designing your loft conversion stairs

Before starting any design plans, it is crucial to understand the building regulations specific to your area. Regulations will address the minimum requirements for stair measurements, headroom, handrails, and safety features for access stairs.  Adhering to these regulations will ensure that your loft conversion is both legal and safe, and avoids any unexpected issues with building inspectors.


When placing the staircase the height of the stairs and landing area should allow sufficient headroom when climbing or descending. The typical minimum requirement is 2 meters, It is important to consider the floor-to-ceiling height in the loft space when deciding upon the placement of the stairs.


Access to the stairs should be easy from the lower floor, and they should not obstruct any existing rooms or hallways. Consider the layout of your house and how the stairs will fit in with the overall flow and functionality of the space. It is also worth considering the possibility of adding a landing halfway up the stairs to provide a resting spot and improve safety.


Loft conversions often come with limited space, so it is crucial to consider the available space for the stairs. However, it is important to ensure that any design choices still meet the minimum requirements for tread depth and riser height, as specified in building regulations.

Design – loft conversion staircase

The design of the stairs should complement the overall aesthetic of your home. Whether you opt for a traditional or modern design, it is important to choose materials, finishes, and handrails that match the existing decor.

Stairs are one of the top features of a conversion project and can be the difference between a great loft conversion and a terrible one!


Staircases can present potential hazards, especially in loft conversions where space may be limited. Consider adding handrails on both sides to ensure stability and safety. It is also crucial to ensure that the stairs are well-lit and free from any obstructions.

Overall, careful consideration of stair placement is vital when converting your loft. Taking into account local building regulations, headroom, access, available space, design, and safety will ensure a well-designed and functional staircase that enhances your loft’s overall appeal. 

Placing the Stairs Above the Existing Staircase

One option is placing the new staircase directly above the existing stairs. This approach allows you to utilize the vertical space effectively and create a new focal point in your home.

By placing the stairs above the existing staircase, you can create a sense of continuity and flow in their living space. This could save space.

One important consideration when implementing this design is the structural integrity of the existing staircase. This will be dealt with by the structural engineer at the building warrant stage.

Another crucial aspect to consider when placing the stairs above the existing staircase is the safety and functionality of the design. It is essential to install proper handrails and ensure that the steps meet building regulations to guarantee the safety of those using the stairs.

Additionally, you should think about the lighting. 

Nothing worse than a dark stair!

Placing a set of stairs above the existing staircase can create unique opportunities for natural light to flow into the house. Installing skylights or large windows near the stairs can enhance the overall ambiance and bring in more daylight.

Furthermore, incorporating storage space within the stairs can be a practical solution to maximize the functionality of the design. Homeowners can utilize the area beneath the stairs for built-in cabinets or shelves, adding extra storage to their living space.

In summary, placing the stairs above the existing staircase can be a great solution to maximize space and create a new focal point in your home. 

just keep in mind that the new stair has to be installed to suit not only the existing floor plan but it also needs to work in the loft, (you don’t want the stair coming up in the middle of a room)

Complex Staircase Designs for Extensive Loft Conversions

If the loft conversion is fairly large and involves multiple rooms, a slightly more complex staircase design may be required.

It may involve adding winders or a half or quarter landing.

Keep in mind that the right staircase design can enhance the appearance of the loft.


Dormer Stairs

A dormer is sometimes required for a stair in a loft conversion for the following reasons:

Headroom and Clearance: Building regulations require a minimum headroom clearance of 2.0m above a staircase to ensure a safe and comfortable passage. In loft conversions where space is limited, a dormer can be added to increase the vertical clearance, allowing for a staircase to be installed without bumping your head.

A dormer can be designed to complement the building, blending seamlessly with the existing structure. It can also create additional usable floor space in the loft, making it more functional for various purposes such as a bedroom, office, or chill-out area.

A well-designed loft conversion with a dormer can add significant value to a property. It provides an attractive and functional living space, which can be a major selling point.

Spiral staircase

It must be said that in my experience spiral staircases generally do not work well.

You will be surprised at how much space a compliant spiral stair takes up.

Here’s why I don’t like spiral stairs

When it comes to loft stairs Spiral stairs take up more room compared to conventional straight stairs for several reasons:

  • Design and Configuration: Spiral stairs are designed in a circular or helical shape. This configuration is inherently space-consuming as it extends outwards in a radial manner. This is in contrast to straight stairs, which follow a linear path.
  • Tight Radius: The curve of a spiral staircase often has a tighter radius, meaning the steps are closer to the central axis. This design minimizes the overall footprint of the staircase, but it can make each step narrower and steeper, which may be less comfortable for some people to navigate.
  • Support Structure: Spiral stairs require a central support column, which can take up additional space in a building. This central column is necessary to provide stability to the staircase and distribute weight evenly.
  • Legal Regulations: Building regulations have specific requirements for the dimensions and clearances of stairs to ensure safety. These regulations influence the design of a spiral staircase and can sometimes result in a larger footprint than initially expected.
  • Aesthetic Considerations: Unless they are done right, spiral stairs can look downright ugly!
  • Accessibility: Spiral stairs are not always the most accessible option, particularly for people with mobility challenges or for moving large items up and down. This can limit their use in spaces where accessibility is a primary concern.

In summary, Spiral stairs take up more room than straight stairs because of their circular design, tight radius, central support column, headroom considerations, legal regulations, aesthetic preferences, and limited accessibility options. These factors collectively contribute to their larger footprint in a given space

If possible a straight staircase design can be a suitable choice. Straight staircases are straightforward in design and are easy to integrate into any space. 

They can be made from various materials, but normally timber, They can be customized with handrails and balustrades to match the overall aesthetic of the loft conversion.

It’s worth taking time with your architect to discuss the options.

loft conversion stair ideas – types of stairs

In some cases, it may be possible to create a space-saving staircase by incorporating storage underneath. This is a practical solution for keeping the loft clutter-free and making the most of the available space. A cool design option is to build a staircase with built-in drawers or cupboards, allowing you to store items such as shoes, coats, or books. 

Perfect if space is at a premium

This solution not only creates more usable space but can also add a decorative feature to the staircase. however, bespoke joinery like this can add a LOT to the cost of a stair.

When planning a loft conversion project, it is important to consider the regulations and guidelines that need to be followed. There are specific regulations related to stairs.

Stairs come in all shapes and sizes, Here are a few different ones:


Mid 6 winder stair

A mid-6 winder staircase is a specific type of staircase design that incorporates winders in the middle portion of the staircase.

Winders are steps that are narrower on one side and wider on the other, allowing the staircase to change direction without the need for a landing or a straight run of steps. In a mid-6 winder staircase, there are typically six winders in the middle section, which means that the staircase changes direction twice within that portion.

This type of staircase design is often used in situations where space is limited, and a compact or space-saving staircase is required. The winders in the middle of the staircase create a more efficient use of space compared to a traditional straight staircase.

Mid-6 winder staircases can be useful In some attic conversions, where space constraints make it challenging to install a standard straight staircase.


Straight staircase

A straight traditional staircase is the simplest type of staircase. As the name suggests, it consists of a straight, continuous flight of steps that go from one level to another without any turns, curves, or landings in between. Straight staircases are characterized by their straightforward design and ease of construction.


2 winder staircase

A 2 winder staircase, also known as a double-winder staircase, is a type of staircase design that incorporates two sets of winders.

Key features of a 2 winder staircase include:

A 2 winder staircase has two sets of winders, usually placed at different levels within the staircase. This design allows for two changes in direction, making it more versatile than a single set of winders.

Like other winder staircases, a 2-winder staircase is space-efficient. It can be used in locations where space constraints make it challenging to install a standard straight staircase.


Bottom winder staircase

A bottom winder staircase design where winders (wedge-shaped steps) are located at the bottom portion of the staircase. 

The bottom winder section is characterized by a set of winders that are narrower on one side and wider on the other. These steps create a change in direction, allowing the staircase to navigate tight or limited spaces at the lower end.

Like other winder staircases, a bottom winder staircase is space-efficient. It can be used in locations where space constraints make it challenging to install a standard straight staircase.


Quarter landing stair

A quarter landing stair, also known as a quarter turn staircase, is a type of staircase design that incorporates a 90-degree turn or a quarter turn in its path as it ascends or descends between two levels.

This type of staircase is characterized by its L-shaped configuration, which includes a landing or platform where the staircase changes direction by a quarter of a circle.

The staircase follows an L-shaped path, with one flight of steps leading to a landing or platform and then another flight of steps continuing in a different direction, typically at a right angle.

At the landing or platform, the staircase makes a 90-degree turn, allowing it to change direction. This design is practical for navigating spaces with limited linear space.

When it comes to stairs for your loft conversion, there is no one-size-fits-all, each project is different and stairs need to be tailored to your design.’

Stair Dimensions

A stair generally has to be 900mm wide, but this can be reduced to 800mm if there are handrails on either side.

The width of the stairs can be reduced further if you only have 1 bedroom and a bathroom in the loft.

In my opinion, 600mm is too narrow, 750mm works well.

Design and Materials of the Stairs


The design and materials of the stairs can also have a significant impact on the overall look and feel of the loft conversion. When choosing a material for the stairs, it’s important to consider its durability, maintenance requirements, and aesthetic appeal.

One of the most popular materials for stairs is wood. Wooden stairs can add warmth and elegance to any space and are available in various types such as oak, walnut, and pine. The type of wood chosen should match the desired look and feel of the space. Wood stairs can be customized to follow different designs.

Glass balustrades can look fantastic (but require constant cleaning) 


They can be used to create a unique and visually striking design. Glass creates a sense of openness and transparency, allowing light to pass through and brighten up the space. 

Choosing the right design and materials for stairs can enhance the overall aesthetic appeal and functionality of a space. Wood and glass are popular materials used for stairs and balustrades.

Safety should always be a top priority when designing stairs. By adhering to building regulations, a safe and secure staircase can be achieved while still maintaining the desired look and feel of the space.

Ensuring Compliance with Building Regulations

It is important to note that the placement of the stairs in a loft conversion need to meet building regulations.

This is to ensure that the loft conversion is safe and meets the minimum standards required by law.

If the stairs don’t comply then it will be very difficult to obtain a completion certificate.

Building regulations are a set of minimum standards that buildings in the UK must meet in terms of design, construction, and performance. Compliance with these regulations is crucial to guarantee the health, safety, and welfare of building occupants.

HeadroomThe minimum headroom for a staircase is 2m. The headroom must be maintained throughout the width of the staircase and over each tread.
WidthThe minimum width of a staircase is 900mm. (can be reduced to 800mm if  handrail is installed on both sides of the stair)
PitchThe maximum pitch allowed for a staircase is 42 degrees, and it should be uniform throughout the entire staircase.
HandrailsBuilding regulations stipulate that Handrails should be provided and should be between 900mm and 1000mm in height.
BalustradesBalustrades should be provided on both sides of the staircase and should be between 900mm and 1100mm in height.

Building control officers from the local authority play a key role in ensuring compliance with building regulations. They are responsible for enforcing the regulations by conducting site inspections, offering guidance, and approving completed works.


In conclusion, when converting a loft into a usable space, careful consideration needs to be given to the placement and design of the stairs. 

It’s one of the most difficult things to get right.

By following the relevant regulations and guidelines and exploring creative design options, the staircase can become a cool and functional feature.

It is essential to choose a staircase design that best suits the layout and space of the loft conversion. 

Options might include placing the stairs above an existing staircase, against a party wall, or incorporating space-saving storage options. 

Moreover, the choice of materials for the stairs can impact the overall aesthetic of the converted loft. However, it is important not to overlook compliance with building regulations when installing loft stairs

The specific regulations related to headroom, width, pitch, handrails, and balustrades must be followed to ensure the safety of the occupants.
