Complete Guide: How to Professionally Organise Under-Stair Storage

The space under a staircase is often neglected, yet it holds immense under-stair storage potential. Whether your staircase is straight, winding, open or closed, you can transform this wasted volume into a functional closet, a custom bookshelf, or even a small home office. This comprehensive guide gives you all the keys to organise under stairs optimally, with concrete ideas, expert tips and mistakes to avoid. Whether you're looking for IKEA solutions, bespoke or flat-pack, you'll find everything you need to create under-stair storage that combines aesthetics and practicality.

Different Types of Under-Stair Storage

Closed Under-Stair Storage: Integrated Cupboard

Closed under-stair storage involves creating a cupboard with doors (sliding or hinged) to conceal the contents. Ideal for living spaces, it allows you to store clothes, shoes, vacuum cleaners or linen. You can choose solid or glass doors depending on the desired style. Custom under-stair furniture is often the best option to optimise space, but IKEA under-stair storage solutions like PAX wardrobes or KALLAX shelving can be adapted if dimensions allow.

Open Under-Stair Storage: Shelves and Bookshelves

Open under-stair storage involves installing open shelves, cubbies or a bookshelf. This gives an airy, decorative look, perfect for displaying books, art objects or plants. However, be mindful of dust and visual order. Under-stair shelves can be custom-made or using standard modules like under-stair storage kits sold at DIY stores.

Winding Staircase Storage: A Technical Challenge

Winding staircase storage is more complex due to angles and varying heights. Often, custom solutions or triangular modules are needed. Options like custom drawers or angled shelves can make use of every nook. Brands like Leroy Merlin under-stair storage offer modular elements that can be adapted.

Other Types: Home Office, Reading Nook, Wine Cellar

Beyond pure storage, the under-stair space can accommodate a small home office, a reading nook with cushions, a wine cellar, or even a pet area. The key is to define the use based on available height: the highest areas (near the wall) are ideal for shelves, while lower parts can serve as storage for shoes or rarely used items.

How to Choose Your Under-Stair Storage: Key Criteria

Measurements and Technical Constraints

First, measure the height under each step (often variable), depth and width. A straight staircase offers a regular volume, while a winding or spiral staircase requires precise measurements at each level. Also consider the presence of beams, electrical outlets or pipes.

Intended Use

Define what you want to store: clothes (require sufficient height for hangers), books (shallow shelves), trinkets, tools or provisions. For frequent use, prioritise accessibility (drawers, sliding doors). For seasonal use, stackable boxes may suffice.

Style and Budget

Custom solutions are more expensive but perfectly tailored. Flat-pack solutions (IKEA, Leroy Merlin) are economical but may require adaptations. Custom under-stair furniture offers a high-end finish. Also consider harmony with your interior decor.

Mistakes to Avoid When Organising Under-Stair Storage

• Neglecting measurements: a few centimetres off can render the furniture unusable.
• Blocking access to technical elements (electric meter, water supply): plan for hatches or removable doors.
• Forgetting ventilation: an enclosed space without airflow can accumulate moisture and odours.
• Choosing hinged doors without clearance: sliding or folding doors are often more suitable.
• Visual overload: too many colours or patterns can weigh down the space.

Maintenance and Usage Tips

For durable under-stair storage:

• Dust open shelves and doors regularly.
• Use closed storage boxes to protect from dust.
• Air out the space occasionally, especially if the cupboard is closed.
• Avoid storing damp or flammable items.
• Check hinges and slides once a year.

Storage Ideas by Staircase Configuration

Straight Staircase

This is the simplest. You can install a linear cupboard with shelves or drawers. IKEA under-stair storage like the BESTÅ or PAX system can be adapted by cutting filler pieces. Consider sliding doors to save space.

Winding Staircase

The space under a winding staircase is more complex. Use triangular shelves or angled drawers. Custom solutions are recommended. You can also create a small home office with a slanted desk.

Open Staircase (without risers)

The steps let light through, giving a modern look. Install open shelves or visible cubbies. Pay attention to the harmony of displayed objects. Open under-stair storage can be very aesthetic if well organised.

Closed Staircase (with risers)

The space is defined by the risers, creating a regular volume. Ideal for a closed cupboard or drawers. You can also create niches within the risers themselves (shoe racks, small shelves).

How to Integrate Under-Stair Furniture into Your Decor

For a harmonious look:

• Choose colours and materials that match the rest of the room (wood, white, black, etc.).
• Add LED lighting under shelves or inside the cupboard to highlight.
• Use designer handles or handleless systems (push-to-open) for a sleek look.
• Mix closed and open storage for visual balance.

Conclusion: Under-stair storage is a smart solution to gain storage space without encroaching on living area.
