In 2007 almost 14% of all offices are vacant, i.e. 5.9 million square meters. At the same time we see a shortage of about 1 million dwellings. A building must be able to be changed over its life cycle to adapt to the inevitable evolving needs of it’s end users. The first real challenge is how to make adaptable buildings without creating unnecessary redundancy. The second challenge is the re-use of old vacant buildings because the available area for erecting new ones is very scarce in the Netherlands. In this matter, old buildings deserve a second chance in their life cycle. We need to be able to measure the transformation potential of office buildings both at location and at building level. To this end, we have developed what we call a ‘transformation potential meter’ (Geraedts, Van der Voordt, 2003, 2004). The meter has been tested since 2004 in practice by a number of market players, and by students of architecture. This has allowed the transformation potential meter to be evaluated and refined in 2006. Two new steps - the financial feasibility scan and the risk assessment checklist – have also been added.

A checklist will be presented that can be used to support the decision whether or not starting a transformation process and a number of go/no go decisions later on. This checklist is partly based on a literature survey on user requirements and preferences with respect to office accommodation and housing, and partly on interviews with parties involved in transformation processes in the Netherlands. The interviewees were asked which features of locations and buildings they considered to be most relevant. An earlier draft of the method has been tested in practice by market players and students of architecture. The five steps method - from quick and dirty to a more thorough, detailed study - include an analysis of the local market and critical characteristics of the location and the building(s), an economic feasibility study and a check on a number of risk factors from a functional, architectonical, juridical and technical point of view. Using veto criteria and gradual criteria, the method shows which features of the location and the building favour successful transformation, and which hinder it.","","en","conference paper","OTB","","","","","Accepted manuscript","","","","","Design & Construction Management","","",""

As a follow-up, this survey 'Good Buildings Drive out Bad Buildings' looks explicitly at the lower end of the office premises market. The office premises in question have been vacated by organizations that have moved to new premises of a higher quality and in a better location. Depending on the prevailing market conditions, a number of the vacated premises will remain empty. This is particularly true of premises that offer the least quality, whose location is less desirable, or whose price/quality ratio is unattractive. This study introduces an instrument known as the Vacancy Risk Meter (VRM), which allows the so-called lower end of the office premises market in a particular urban district to be defined at an early stage.
The study was aimed at the developments in the office premises market in Rotterdam between 1996 and 1999. This period was characterized by the presence of a relatively high percentage of chronically empty buildings. In the subsequent period, from 1999 to 2002, a more favourable economic climate and altered market forces led to many of the empty buildings being rented out once again as office premises. From 2002 onwards, a growing economic recession has meant that the number of chronically empty buildings is once again on the increase: the cycle is repeating itself.
The Vacancy Risk Meter (VRM) indicates at an early stage which office buildings at which locations are likely to be vacated first due to changes in the market as the current tenants relocate to higher quality premises. This allows the potential and risks for the preservation of the office premises market to be determined for the selected buildings and locations. The VRM therefore allows the lower end of the office premises market to be defined for a particular urban district.
By defining the so-called Vacancy Risk classification for many different premises, a clear picture can be formed of the relative quality of each in relation to the others. A complete overview can be generated at supply level for any given urban district or area of the potential lower end of the market.","Vacancy Risk Meter; transformation; instrument; lower end of the office premises market; structurally vacant office buildings","en","conference paper","Department of Architecture, the university of Hong Kong","","","","","Accepted manuscript","","","","","Design & Construction Management","","",""

(TU Delft Design & Construction Management); van der Voordt, Theo (TU Delft Real Estate Management)","","2003","A large number of office premises seem difficult to rent out because they no longer meet the demands of the market. A solution must be found for these premises and also for office buildings that have been empty for longer periods. Reallocation or transformation to other functions such as homes can be envisaged here. In addition, due to the lack of available locations for building homes, corporations and project developers are desperately looking for alternatives. The transformation of offices into homes can also be a good option for this objective. In the current study answers are provided to the questions: how many and which office buildings stood empty in a particular area of Rotterdam; which groups of households can be identified for the transformation of empty office buildings into homes; what is the demand profile of these groups; and with which instruments can the transformation potential of empty or soon-to-be empty office buildings be measured.
Conclusions and recommendations
An important veto criterion for the transformation process is the dovetailing with the council policy; offices in residential areas should in preference be transformed into dwellings. Favourable features such as the availability of parking spaces, a positive ambience and other characteristics of an area suitable for working in increase the chance of renting as office space. Old buildings in the area, a bad net/gross ratio, poor energy performance and structural deterioration are, in contrast, unfavourable factors when renting out office buildings. Buildings with these characteristics are more readily considered for transformation. The type, accessibility and size of the dwelling are of critical importance when weighing up the decision of whether to rent or buy a particular home. Priorities vary between target groups. The lay out of the dwelling and the level of relaxation provided appear to be of secondary importance. People seeking accommodation are more concerned with the distance to a tram, bus or metro stop and a railway station, and less concerned with the frequency of public transport.
A number of test cases have shown that the developed Transformation Meter is a good tool for assessing for specific city areas (step-by-step, from a global to a detailed perspective) what the market supply of empty office buildings is, what the market demand is with regard to target groups and requirements, and the match between the two from the point of view of availability and buildings.","Transformation potential; instrument; offices; homes; living; structurally vacant; revising","en","journal article","","","","","","Accepted manuscript","","","","","Design & Construction Management","","",""

Begin jaren negentig was op ruime schaal sprake van structurele leegstand in kantoorgebouwen. Aan het einde van de negentiger jaren heeft de kantorenmarkt zich hersteld en is de vraag fors toegenomen, vooral in het midden- en topsegment. De huurprijzen verbeterden en de leegstand nam sterk af. Een groot deel van het bestaande en nieuwe kantooraanbod was gemakkelijker te verhuren, zelfs verouderde gebouwen op minder courante locaties.
Nieuwe dreigende leegstand
Op veel locaties worden eind jaren negentig initiatieven ontplooid voor kwalitatief hoogwaardige nieuwbouw in de kantorenmarkt. Een groot deel van de nieuwbouwproductie is echter niet het gevolg van een uitbreidingsvraag, maar van verhuisbewegingen.
Door hoger wordende kwaliteitseisen trekken kantoororganisaties naar nieuwe panden met een hoge gebouwkwaliteit en gelegen op een hoogwaardige locatie. Een deel van de achtergelaten panden komt naar verwachting leeg te staan. Dit betreft met name gebouwen die op locatie- of pandniveau de minste kwaliteit bieden of een ongunstige prijs/prestatieverhouding hebben. In de woorden van FGH: 'Good buildings drive out bad buildings'.
Dat is de reden waarom er een instrument is ontwikkeld waarmee op voorraad- en gebouwniveau de zogenaamde onderkant van de kantorenmarkt in een bepaald stadsgewest in kaart gebracht kan worden.","onderkant kantorenmarkt; potentiemeter; vetocriteria; graduele criteria; instrument; beoordeling","nl","report","Delft University of Technology","","","","","","","","","","Design & Construction Management","","",""

Necessity of adaptation measures In 1985 the National Housing Counsil (NWR) started the experiment Building Adaptable Housing to assess which requirements dweUings have to meet in order to make them suitable for handicapped people, both as visitors and as occupants. First, a list of Requirements for Building Adaptable Housing has been drwan up (NWR 1987). Next, 40 projects with adaptable dwellings have been realized. In the beginning of 1992 on the basis of these experiences and the comments upon the first vers ion of the Requirements a Manual Building Adaptable Housing is published. This manual comprises not only data on the market for Adaptable Housing and on the applicability of the principles, but als a review of various example projects. Besides an adjusted version of the Requirements for Building Adaptable Housing is included in the Manual. These requirements are more directly focussed on newly built dweUings than before. For the rehabilitation of the existing stock the NWR wiU develop special requirements. To this end in 1990 an experiment 'Adaptable Rehabilitated Housing' has been started. The present survey is part of a follow-up experiment and its aim is above all to get more understanding of which adaptability measures should be given priority.","","nl","book","Onderzoeksinstituut voor Stedebouw, Planologie en Architectuur OSPA","","","","","","","","","Onderzoeksinstituut voor Stedebouw, Planologie en Architectuur OSPA","","","",""
