• With finished sizes from all masses 2% for clean taken off.
• The height is counted starting from upper edge cellar floor.
• With not made a cellar under buildings starting from one counts.
• With not developed attic the height up to the surface of the soils over the highest full storey is counted.
• With developed attic up to the exterior surface of the enclosing walls and covers one counts, without roofing

• Balcony and terrace parapet walls

• Outside staircases
• free standing chimneys
• Roof systems and - dormers with > 2 m exposed surface
• Pits and channels.
