The cost of housing and building control Stefán Ingólfsson, Engineer and Lecturer at the Technical University of lceland Property prices increase for a number of reasons. This article deals with the effect of public action and methods on property prices. Public bodies can, if they want to, use different methods to lower prop- erty prices. Lack of building sites, increased requirements to buildings and a slow building control process have on the other hand resulted in higher property prices. In this article it will be shown how this has happened. To start with, let's look at two basic aspects of property price; the material value of buildings and the price of build- ing sites. Together they constitute market price. The part of the site varies considerably. In expensive shopping space the part of the site can amount to up to 50% but less in the case of less expensive prop- erties like housing. In 2000 the site accounted for 11 % of market price for an average flat in a block of flats in Reykjavík. The physical value of the flat was according to this 89% of the total price. Shortage of building sites increases prop- erty prices The price of building sites contin- ues to rise. The author has studied the development of land prices in the Capital area from 1975 - 2000. During this quarter of a century the price of land rose about 65% in real terms, that is 2% a year. In 1975 the price of a site was 7% of the market price of an average flat but had increased to 11 % in 2000. The rise in site price resulted in a 4% rise in the price of housing during this period. The rise of site price came about for several reasons. The price of land has gone up in real terms during the last decades. The increase in price is most obvi- ous in the capital area and within its sphere of influence líke the southern and western part of the country. Accessible building areas have been used up in the capital area and the supply of building land has not met demand in at least two decades. The demand for new housing has therefore not been met for a long time. There is a yearly need for new housing which equals the increase in the number of households. The number of households increases at a faster rate than poulation increase. More and more individuals form households so that the demand for housing grows grows more than twice as fast as population increase. Planning authorities in the Capital area do not realise this and are therefore unprepared. To the natural increase in the population of this area is added the number of peo- ple moving from other parts of the country and from abroad. To meet the demand for new construction it would have been necessary to build 1.300 flats a year during the last 15-20 years instead of 1.100 as has been the case. The results are an accumulated demand and increased site price. Material value Material value of housing is build- ing cost minus amortization totalling 89% of the price of housing. During a long period the cost of building is the most important factor in the cre- ation of the price of housing. It has during the last decades increased every year 1 % more than general price increase. Building consts can be divided into two. Around 3/4 of it are so-called direct costs related to the purchase of building materi- als and labour directly connected to specific parts of the building. Approx. 1/4 is conected with the building as a whole and is termed indirect cost. Public bodies play a decisive role in influencing both of these costs. Let¥s look at the direct cost. Te cost of building materials is to a large extent decided by official decrees. The quantity of building matterials like concrete and steel is dictated by the building regulations. The stricter the rules the higher the material cost. The same applies to the labour of the building trades. Official bodies have fbeen increasing demands for decades. Many spe- cialists are now of the opinion that buildings have become unneces- sarily material intensive and expen- sive. The director of building at the University of lceland has stated that by revising the building regulations it would be possible to reduce build- ing cost by 15% and a professor at he Department of Engineering at the same university told the author of this article that lcelandic build- ings possibly used up to 20% more materials thatn necessary. These demands are however still being increased and the cost of building increases. Denmark has seen similar development but The Danes have now come to their senses and are revising building standards with the goal of reducing building costs. Indirect costs Indirect costs are e.g. design, supervision, management of build- ing work and building compa- nies. These costs have been on a constant rise because building authorities are constantly demand- ing more work by designers and building contractors. Indirect costs anr now considerably higher than they were 25 years ago. The work of architects, engineers and other technicians takes up more and more time. The same applies to the management of building contrac- tors and on site management. This 40 avs
