UP GRANDE staircase: contemporary steel interior stair with wooden treads

A generous living-room staircase that still saves space

The Up Grande is the living-room version of the UP model, created to connect two main levels such as lounge, mezzanine or night floor. It is wider and more comfortable than a simple secondary stair but keeps a genuinely space-saving layout. This makes it easy to integrate into a living space, offering a full-size stair without blocking views or overloading the floor plan.

Contemporary design, custom-made in Belgium

With its double steel stringers, projecting solid-wood treads and minimalist handrail, Up Grande brings a contemporary look to your interior, from modern lofts to more classic refurbishments. Every staircase is made to measure in Belgium: floor height, available width, tread type, timber tone and handrail finish are adapted to your project. The result is a design living-room staircase, more economical than a traditional built stair yet robust, durable and straightforward to install by a skilled DIYer or by Spira’s fitting teams.

Why choose the UP GRANDE staircase ?

A true feature stair for everyday living spaces

The Up Grande is a genuine living-room staircase, not a back stair or attic access. Its generous width, consistent geometry and high-quality materials provide:

  • a smooth, natural walking rhythm,

  • comfortable use even with busy hands,

  • a strong feeling of safety for all users.
    It is particularly suited as the main stair between lounge, night floor or mezzanine in open-plan interiors.

Double steel stringers for stiffness and long-term stability

Technically, Up Grande builds on the UP structural concept, upgraded for intensive use in living areas. The stringers are cut from thick steel plate to deliver excellent stiffness. This twin-stringer structure:

  • ensures a very stable, vibration-limited stair,

  • keeps a slim, graphic profile despite the increased width,

  • easily carries solid-wood or steel treads.
    You get a contemporary steel interior staircase designed to stand up to many years of daily use.

Wooden or steel treads to match your interior style

By default, Up Grande comes with solid-wood treads (varnished beech or other species on request), but it can also be specified with steel treads for a more industrial character. This flexibility lets you:

  • align the stair with your flooring, joinery or furniture,

  • create a strong contrast between steel structure and treads,

  • choose the mood, from warm and homely to clean and technical.
    The staircase becomes a real design element rather than a purely functional access.

Space-saving, economical and fully made to measure

Thanks to the space-saving DNA of the UP model, Up Grande makes smart use of the available width. The stair width can be adjusted, and the going is dimensioned for intensive use, delivering comfortable climbing without demanding an oversized opening. Compared with a fully built traditional stair, it offers:

  • a more cost-effective solution,

  • simpler installation,

  • greater freedom in design,
    while still being a fully made-to-measure staircase.
