The Kompact Modular Staircase is a clever design with a central interlocking spine which can provide a straight, L-shaped or U-shaped winder staircase. With powder coated steel vertical spindles and central spine, the Kompact staircase is extremely robust. The solid beech treads are available in two tints – Light Beech or Dark Beech, which combine perfectly with your choice of steel colour from Black, White or Grey. The Kompact modular staircase is also available in two widths to suit every project – 740mm and 890mm.
Just choose the format for your project (straight, L or U), the right width and then your colour choices and then it’s as easy as that!

The Kompact Modular Staircase kit can be installed with a clockwise or anti-clockwise turn using the quarter turn set of treads. You decide when you fit the staircase!
Generally, it is best to form the opening for the staircase at least as big as the staircase layout itself.
The standard kit has 13 risers (12 treads) and the tread rise is adjustable from 170mm to 235mm, although UK regulations have a maximum tread rise of 220mm. This means that the standard kit will suit floor to floor heights of up to 3030mm (or 2850mm to comply with UK Building Regulations for maximum tread rise). If your floor to floor height is higher than this, you simply need to add additional tread kits as required. If your floor to floor height is lower than this, you use less treads.
The individual tread rise and going is achieved by adjusting the central tread support modules to provide your overall correct staircase height. These are supplied in the kit, together with all fixings and fittings required plus clear installation instructions. You’ll also find installation videos on the Knowledge Centre Page of this website. (But, don’t forget, the manufacturers have taken great care to provide accurate and clear installation instructions – there are no shortcuts! Don’t be tempted!)
The going or depth of the treads is adjustable on the Kompact staircase from 180mm to 220mm but the UK Building Regulations require a minimum tread going of 220mm and your chosen configuration should bear this in mind.
Powder coated steel riserbars are available as an accessory kit to fit between the open treads to satisfy the requirement for the gap to be less than 100mm.
