Conclusions

• After the expansion in the period 2000-2002, a
  number of buildings under construction is rapidly
  decreasing
• Building works last around 8 years
• Average useful floor area of one storey is around
  62 m2, and most frequently buildings have ground
  floors and one storey

23

• The total planned cost of building 1 m2 is around
  786 KM, of which the share of costs of material
  is around 50, labour costs 30 and land, land
  preparation and permits, projects and similar is
  20
• During construction, the largest investments take
  place in the first year, and make around 30 of
  the total planned cost of building works. The
  share of investments in each next year is 10 in
  average.
