Urban City Strategy

A transformation is to be initiated for the urban area in order to give it a new, positive identity, in line with the “New Leipzig Charter” (NCL) for European cities. The basis is an urban development framework plan. This envisages the new building for the Albtal-Verkehrsgesellschaft depot being housed in a predefined building block, because its present location in the middle of the town centre obstructs important development areas. In conjunction with the district development of the former ELBA site and the Ettlingen-West railway station, the ‘loose ends’ of adjacent districts and uses are also to be taken up and woven into a coherent use and structure concept. The Ettlingen-West station will be developed as an intermodal hub and connections to the surrounding transport network improved. The open space element is to be enhanced by green open spaces.

Site Definition

The site offers the opportunity to generate development momentum, to carry out urban renovation in places, and to introduce a new urban component. In addition to providing the new depot, this district development will enable previously inaccessible areas to be returned to the urban community, and will create space for about 2,000 jobs, some 200 affordable rental flats, and other uses. The development of the site itself will remedy shortcomings in the transport network, and create a new atmosphere for the station as a place of arrival. Such a dual inner development can also contribute to climate change adaptation, climate protection, and the mobility transition.
The west of Ettlingen is currently seen as a transitional area between the compact town core and the large-scale structures of the ‘West’ industrial area. Its favourable location in the immediate vicinity of the town centre, on the one hand, and its good transport connections, on the other, increase the pressure for change in this urban area. It is expected therefore that it will develop into the strongest ‘conversion zone’ in Ettlingen. The Rheintalbahn main railway line has a great dividing effect and is a significant source of noise, but also provides great development potential. Apart from the listed buildings around the railway station, the existing edifice is not worth preserving, and the existing functional structures are fragmentary and need to be concentrated and enhanced.

How Must Metabolism and Inclusivity Be Developed and Connected?

The aim is to develop an urban design draft that substantiates the objectives of the framework plan, specifies the urban structure (gradation, height development, etc.), makes proposals on building typologies, and further formulates the green and open spaces. The urban area should continue to be strongly typified by ‘work’. However, the declared aim is to increase the density of workplaces in terms of area and thus also to create space for complementary uses, so that a lively urban life can emerge. Even for office and service uses, the quality of the surroundings, local amenities, social facilities, and green open spaces and meeting places are locational advantages and sometimes criteria for the attractiveness of an employer. Hence, streets and squares should not only be planned in terms of their development function, but also with corresponding amenity and open space qualities.
The three basic principles of the NCL – the ‘Just City’, the ‘Green City’, and the ‘Productive City’ – should be specifically applied to the urban design as guiding principles of Europan 16 ‘Living Cities – Lebendige Städte’. The idea is to develop the Ettlingen-West railway station as an intermodal transport node (mobility hub) and as a valuable place for arrival. To this end, the image profile of this urban space must be improved in order to make it an urban pivot for the different transport interconnections that is proportionate to its function and significance.

Questions à propos du site

Is there any additional material about the existing buildings on the ELBA-site (floorplans, sections, etc.)?

The city will scan old plans and they will be made available on the Europan Website as soon as possible.

21.05.21. The material is now available (folder: New_Docs_After_Launch)

Due to insufficient information about the structure of the depot, it is difficult to find an appropriate answer in this area. A rough spatial programme / information on the dependencies of the depot (uses, track routing, etc.) would be helpful! Simply adopting the existing planning does not seem to make sense for the entire area.

The invitation to tender on page 38 stipulates as a binding requirement that the division of the space required for the new AVG depot is to be taken over 1:1 from the outline planning. The internal dependencies in the division of the depot (operating procedures, technical requirements for switch spacing, rail radii, etc.) are so complex that changes here can definitely not be recommended to the participants. Therefore, in Figure 32 on page 39 of the tender, the area shown in red is marked as an area that is not to be changed. 

The relocation of the AVG depot from the city centre to the new site of the former Elba company is the primary goal for Ettlingen's urban development. Only in this way can the areas of the current depot in the city centre be freed up. In the run-up to the framework planning, the various possibilities for a depot arrangement were therefore examined with the AVG in an intensive planning process. The arrangement found in this way and anchored in the framework planning represents the best compatibility of technical requirements, internal operational processes and efficient use of space. The genesis of this planning process can be found on page 7 of the "Documentation for the urban planning study of the future AVG depot" (annex to the Europan competition).

Even if formally a deviation from this specification does not automatically lead to the exclusion of the competition works, a change in the depot layout makes the overall planning no longer feasible. Since the city of Ettlingen attaches great importance to the implementation of the ideas and plans generated in Europan 16, participants are requested to take this binding requirement for the depot arrangement into account.

please define the requirements for the train depot, such as light, column grid, access for employees, access for maintenance, access to road etc.

With regard to the rail depot, the same requirements apply as for the bus depot. A special column grid, accesses for employees, maintenance, etc. cannot yet be specified more precisely at the current planning stage. Here, too, an enclosure is possible or even desirable. A clear room height of 6.0 m is also to be assumed. The rail depot is to be connected to the access network for road traffic.

please define the requirements for the bus depot, as height, enclosure (open - close), access to road etc.

The bus depot can be enclosed. This is even advantageous in terms of immission control (noise). The enclosure can be made either open or closed - although this naturally has an impact on sound propagation. Ventilation of the building must be ensured. The bus depot must be connected to the development network of the neighborhood. The clear height for the bus depot is to be assumed to be 6.0 m.

On the site visit it was mentioned that (Auslobung , ABB 27) building 10a is worth keeping, while in the brief it is pointed out that building 19 is worth keeping, please clarify.

The representation in Fig. 27 of the invitation to tender is correct because this building has the better building fabric than all the other buildings. Theoretically, it is also possible to continue using other buildings, such as Building 10a. However, it must be remembered that this must be compatible with the requirements of the depot and the target minimum occupancy rate. The framework planning is therefore based on the demolition of both buildings.

Please send some information on the ongoing projects Bauhof and Stahlareal.

Initial consideration studies can be provided for the ongoing Bauhof and Stahl-Areal projects (see New Documents Folder on the server).

On the site visit it was high lighted that Dieselstrasse and Bahnhofstrasse meet in the middle of the south end combine in a ramp to underpass the rails to Goethestrasse. In PS-M9_Stadtebauliche_Studie page 42 - it shows a different connection. which one we should follow or follow both?

The connection to Goethestraße shown in the urban development study p. 42 is now obsolete. The current plan is to merge Dieselstrasse and Bahnhofstrasse in the middle of the southern end and unite them in a joint connection to Goethestrasse, as shown during the site visit. Fig. 36 on p. 40 of the invitation to tender depicts this currently planned development approach. The planning is provided as a CAD file (check New Documents folder).

the cut off bit by the rail curve on the very south west tip of the site, now home to hobby gardeners - is outlined as storage area in PS-M9_Stadtebauliche_Studie page 16 while on site visit it was mentioned to be open up for buildings, please clarify

The future area in the Gleisdreieck (in the southwest of the site), where allotment gardens are located today, is designated in the framework plan as a ground-level storage area. In principle, it is also possible to build on this area. In this case, the storage areas are to be provided in a different location. In the case of the storage areas, care must be taken to ensure that these are areas for larger stored goods (sleepers, rails, contact wire masts, etc.), which require corresponding shunting operations. Additional building over the storage areas would have to be compatible with these requirements, which seems difficult to imagine from a realistic point of view.

PS-M9_Stadtebauliche_Studie page 16 - Verortung der Flächenbedarfs - Changes - Storage place (green) change in Position, change in height? Office (white) used by AVG or different user? change in Position? I assume office (red outline) is used by AVG, it houses 1700 sqm possible to add another floor and a different user?

As shown on page 16 of the urban planning study, areas for storage inside (green area) can also be demonstrated elsewhere. A change in height is possible if accessibility by larger vehicles continues to be guaranteed (e.g. in an underground garage that is also used for deliveries). In principle, the use of office space by AVG can be assumed for the development on the west side of the site along the Rhine Valley railroad. In principle, leasing to other users is of course possible. Only the areas on the first floors that are relevant for the depot (workshops, service stations, etc.) are mandatory.

PS-M9_Stadtebauliche_Studie page 16 - Verortung der Flächenbedarfs Position of Bahnhofstrasse can it follow along the rails? does it have to be connected to the depot?

The connection of Bahnhofstrasse to Goethestrasse should preferably be made in accordance with Fig. 36 in the tender. The figure shows that the connection of Dieselstrasse and Bahnhofstrasse is planned in a joint node as a connection to Goethestrasse. The depot will also be connected via Bahnhofstrasse, in particular to keep the northern Dieselstrasse free of additional bus service trips.

Are any CAD files available with the new rail layout and street connecting to Goethestrasse?

 The planning is provided as a CAD file (check the New Documents folder on the server).


What will be relocated with the loading ramp and what will be accommodated in the storage areas?

The outline plan provides for a loading ramp with siding and storage capacities of approx. 10,500 square meters in the future track triangle in the southwest of the site (cf. page 16 of the urban development study for the future AVG depot in Ettlingen, outline plan). Among other things, materials for track construction (sleepers, rails, catenary poles, etc.) are to be stored on the storage areas. A special roofing is initially not required for this.


We've seen that in the given brief are presented some potential masterplans, how much should we consider them in view of our design intervention?

The master plan can be used as a basis for urban development, but it only represents an initial conceptual framework. This master plan is only binding with regard to the future AVG premises, which are marked in red in Figure 32 on page 39 of the Europan16 competition. This area perimeter and arrangement is to be adopted 1:1 in the further planning. All other areas can be completely rearranged, structured differently or otherwise overplanned. The participants are completely free to find their own solution

Which is the expected density of the built volume in the site plan? are we expected to respect a certain percentage between greenery, residential, commercial within the building site?

The utilisation ratios are shown under point 3.2 of the competition (pages 44-47). The site is to accommodate about 2,000 workplaces and about 200 residential units. This corresponds to the 116,600 m² gross floor area shown. Against the background of an economical use of land, this space utilisation is to be achieved as a minimum value in the planning. The desired distribution of uses results from the number of desired workplaces and residential units. Retail space and social infrastructure can be added according to the planners' own assessment.

What is the maximum height of buildings?

No height limit is set. The building heights are freely selectable.

About the train station, are we expected to re-design and potentially relocate the main building of the railway station or should we design and re-organize only the open spaces around it?

The station building is a listed building and should be preserved in its current state. Proposals for future use can be made here. The former goods hall to the south, which is also a listed building, must be removed from its current location because of the future AVG depot. The building can be demolished in the planning or relocated to the area of the station.

Always in the given brief, we've seen that the railway company own a part of the project site, should need a certain amount of space reserved to their needs. Should we consider these volumes in our masterplan? And if so, how much in terms of square meters would it be?

The requirements for the AVG depot are shown in the tender in Figure 32 on page 39. With the adoption of this area perimeter, the AVG's concerns are covered. Additional potential areas beyond this therefore do not need to be taken into account for the AVG.
