Florijn Noord. An example of renovation, Bijlmermeer. Chapter 6 --------------------------------------------------------------------------------------------------------------------- 6.1.1 OUTLINES OF THE RESTRUCTURING PLAN The F neighbourhood is located on the Southeast area of the Bijlmermeer. Its borders are clearly defined by a vehicular gird (Dolingadreef, Bijlmerdreef and Gooiseweg). As mentioned, the renovation project was driven by the restructuring urban plan. This was designed in 1997 by the Delft urban planner Rein Geurtsen. Zeger Woudenberg is the designer of the landscape project (de Haan & Keesom, 2004). At the end of 2007, the renovation and most of the new low-rises in the ‘F’ neighbourhood were already realized. However, the works will be completely finished in 2009. The F neighborhood during the works (before spring 2005) The key words of the plan are ‘densification’ and ‘differentiation’. They were implemented by means of selective demolition of existing high-rise and construction of low-rises in the home ownership sector. The objective was to increase the residential incidence with 10% (at least 65 people per hectare) in order to decrease uncontrolled public spaces and increase social safety. Free parking places close to the high-rise and surrounded by green areas will have substituted the collective garages. On the basis of those assumptions, the plan reorganizes the demolished lots into a new urban layout. Higher recognizability of buildings is obtained by means of different volumes (shapes) and more types (high, middle and low-rise) and use of different materials. This concept is based on a resident survey. It emerged that residents would have accepted partial demolition and that they had a large interested in affordable home ownership. Also technical investigations for possible physical configurations of the high-rise supported the entire design. In its original urban configuration, the F neighbourhood had five high-rise blocks. The blocks followed the building layout presented in Chapter 5 when describing the Bijlmermeer. All dwellings were in the social housing rental sector. According to the urban restructuring (Action plan 1996), one block was completely demolished while the remaining blocks– Klein Frissenstein, Klein Fleerde and Florijn – were partially demolished. The first two blocks are now comprised in the so-called Florena and are integrated into a clear urban structure with a more compact residential pattern. They play the role of recognizable vertical signs in the landscape (see especially the distinctive colors of the parapets. See also Chapter 4, Tab 3). As shown in the table below, after the completion of the demolition and renovation works, the total number of housing units decreased from 1395 dwellings in the social rental sector to 333 dwellings, and to 108 in the owner-occupied sector.

Florijn Noord. An example of renovation, Bijlmermeer. Chapter 6 --------------------------------------------------------------------------------------------------------------------- In the lot called Florena (including portions of the Fleerde and Frissenstein high-rise blocks) there are good examples of ‘high-level renovation’. In this case, the tenants did not stay in their dwellings during the works; they have been re-housed (permanently or temporarily) elsewhere. The bearing structure was preserved. But some of the inner walls were moved to combine housing units to large dwellings. In both high-rise blocks, the storage spaces on the ground floor have been converted into maisonettes with a street front door. After transformation, all the units were ready to be put on the home ownership market. The next table identifies the dwellings by tenure form after renovation. It is evident that the predominance of low-rise is in the homeownership sector. New low-rise blocks, in fact, were attached to the high-rise (Frissenstein) or built close to the bottom of each block (Fleerde). DWELLINGS TYPES IN THE FLORENA: FRISSENSTEIN AND FLEREEDE 4 Apartments in high-rise, home ownership 80 Independent dwellings one on the top of the other 2 Single family houses, home ownership 124 Single family houses, social rental sector 50 ERA Bouw, a company that in the ‘60s developed a rapid high-rise building method, was the developer of the renovation for the Fleerde and Frissenstein. When renovation of high-rise was under discussion, ERA accepted the challenge of readapting the dwellings to meet the new requirements and repositioned them on the home ownership market. In 1994, in association with the Steering Committee on Social Housing Experiments (SEV), the housing association, the District and two architectural firms, the company carried out a study for possible actions (van Hoogstraten et al. 2002). In 1996, results stated that ‘the remaining dwellings could be made suitable for another group of residents, provided that they were integrated into low-rise developments’. Architect Duinker & van der Torre were charged with the renovation of the high-rise, architect Splinter with the new low-rise. The work was finished in 2005 and all the dwellings have been sold 4 de Hann, H., Keesom, J. (2004) New urban layout of F neighborhood.
