The basic kit is available with either 10 or 11 steps with balustrade and handrail to one-side.  Compatta space saving stairs can be customised to meet your specific requirements through utilisation of a wide range of accessories.  The innovative Compatta staircase is supplied as an easy to install kit, complete with an installation manual and video.

Compatta Example Configurations  

The Compatta alternating tread staircase is suitable for use as secondary staircase, for access to a mezzanine floor or access to a loft conversion with a single room (plus bathroom).  It has been designed to be compliant with all relevant standards.  However, the adjustable nature of the staircase may allow the installer to complete the installation without adhering to UK building regulations Part K.

A safety-riser kit (sold separately to the standard staircase kit) is required for compliance to the 100mm open riser regulation.

Responsibility for building regulations and health and safety regulations compliance lies solely with the customer and installer.

Safe and compact loft conversion stairs for family home

Loft conversions are a popular way to add valuable space to a home. One of the biggest challenges with any loft conversion is where to put the stairs. Also, what type of staircase should you go for? Home owners Bobby and Simon had exactly these concerns when planning the conversion of the loft in their family home in Norfolk.

As a result of there not being enough room for a full-size staircase, space saving stairs were needed. In addition, the loft conversion stairs needed to look good and be safe for use by young children.

“We love the stairs and everyone who sees the extension always comments on how nice they look”

Bobby and Simon
