Very interesting mezzanine project in the apartment in the Praga district of Warsaw. Total area of mezzanine 4 sq. mtrs. Construction is narrow (less than 1 metre) and long (over 4 metres). We managed to install structural beams in one piece (4,1 metre long). That created really stable and safe double bed for two boys. Vertical structural beams are integrated with ladder stairs. Materials used: pine. Mezzanine function: sleeping area. Mezzanine gives the opportunity to enlarge the living space for a family with children.
