Intro• The aim is to demonstrate sustainability arguments 

using house price data with particular emphasis on CEE circumstances

• Analysis  of house price and turnover data on Budapest, Hungary, for the period 2000-09 (SOM, fixed time-windows) + field inspection of upper market cases + interviews of academic, non government, public and private sector experts

• A variety of locations and typical market segments• The findings suggest that sustainable innovation 

features are largely absent in this period, although future markets are likely to be different in this respect.

Environmental-ecologic sustainability

Social-cultural sustainability

Economic -financialsustainability

The current theory of sustainability

Sustainability aspects relevant for urban real estate development

1. Energy efficiency in buildings 2. Use of renewable energy in buildings 3. Pollution control in building4. Real estate quality5. Real estate affordability6. Real estate diversity7. Optimal density for a block/neighbourhood8. Public transportation availability 9. Traffic pollution 10. Social cohesion in the neighbourhood/city/region11. Communicativeness in local/regional planning 12. Innovativeness of the region

Urban property development – how sustainable?The right mix of investment and regulation fosters

1. Quality2. Affordability3. Diversity (evolutionary argument)

OBS: Budapest is more affected by the global crisis than other European cities!

Developments in selected Hungarian municipalities

• The urban property development of Budapest is private driven

• Development activity has spread outside cities to former industrial areas, logistics centers, villages and Greenfield sites. 

• Even amidst such harmful tendencies, sustainability is gaining more importance in this country too…

• We are looking for smaller, niche developers and a demand driven approach!

Property value creation and price setting

(1) Lack of an ‘unsustainability discount’ (exception: energy costs of homes)(2) Unrealistic price-setting by the seller in a consumers market (falling demand; oversupply, e.g. Residential parks).(3) Political issues: Changes in land ownership and land use involve political and lobbying practices – corruption too – that are extremely unsustainable (4) The mismatch between the prices paid for land at the height of the boom and prices expected from the sales or leases of the completed floor-spaces

”We expect that all sorts of things will increase the value – some of them are sustainable”

High price areas –  how sustainable are they? 

To find out we need field inspection

FindingsThe SOM analysis: • In Budapest contain relatively high priced cases and cases 

with high turnover were found in very specific places• However, the composition of almost all high price cases 

change every year; e.g. One year the highest price is for historic inner city and the next it is in suburbia

The field inspection (upper/upper-average market cases): • Within the high price segments 15 cases were picked; most 

of them fall short of many sustainability criteria • One or two cases may be evaluated as sustainable; this is 

largely due to the cultural dimension• Often also mixed nature of the developments and ‘green’ 

too ; and reasonably good public transport accessibility• Disappointing is a lack of innovativeness ~ sustainability

Conclusions• Depending on the selection of data/variables it is possible to 

illustrate differences in urban structure using the SOM• However, while it is relatively easy to illustrate price premiums 

it is far more difficult to relate them to any sustainability factors• Budapest comprise an interesting case due its huge contrasts• The necessary field inspection confirms that, of all possible 

sustainability elements, only the cultural dimension is strongly present ; other elements associated with sustainability  (mixed, green, public transport) show up sporadically

• The new stock is not as diverse as  the old stock• Innovativeness is absent within this context; however, in the 

future markets the situation may change
