The Gymnasium Waldstraße is a high school with a long tradition in Hattingen. The school site for around 900 pupils consists of the listed main building, the adjoining 1-storey foyer with WC facilities as a connecting body and the extension building built in 1969, the so-called ‘new building’. Furthermore, a pavilion, a sports hall and a canteen building were built in 1970 and 2012. The building stock has a different level of refurbishment congestion. As compensation for the acute lack of space, the city of Hattingen is planning to expand the school location. In 2022, a feasibility study was carried out as a first step. The documents are provided as an annex for information purposes, the study does not serve as a binding guideline in the context of the competitive task. The audited analysis of the feasibility study results in the political decision of a reduced, to be implemented space program of 10 classrooms and 2 chemistry rooms including adjoining rooms. The location of these rooms remains for the competition participants to plan according to the design, whether as a new building, an increase or an extension of the existing building. Pollutant tests have shown that the facade of the 70s building is polluted and needs to be replaced. A facade renovation for the building is therefore intended for every solution approach. For the sports hall, an increased pollutant load could be detected throughout the building. Due to the intended use, there are increased requirements for indoor air quality, which are not met in the inventory. Also, the current hall is no longer adequate for the number of students. The competition task therefore includes the planning of another new building, which is to replace the current sports hall. For this, the accommodation of a 2-field hall is provided, which can be divided into three separate areas. The current location of the hall is proposed by the promoter, but the competitors can also develop alternative solutions. The requirement to consider the building stock in the context of the monument and to find a holistic solution for the school location is one of the important challenges for the participants. An intensive examination of the inventory and the design of a holistic concept for the school grounds is expected. The parking lot west of the school building can be removed and covered with a new building. The pavilion as well as the entrance hall with toilet facilities between the old building and the 70s building can also be dismantled. In the event that the entrance hall is removed, a new entrance area of the school must be planned in the design. The location of the toilet facilities must be planned according to the design. If an extension of the 70s building with connection to the old building is planned, this must be designed in accordance with the monument. The aim of the competition is to summarize the buildings to be realized and the building ensemble resulting from the different times in an overall concept that also allows future development opportunities at the school location. The question of new construction, expansion or expansion of the existing building is to be investigated in the course of the competition work, with the aim of finding a monument-appropriate solution in a modern architectural language. One of the tasks for the participants is to form construction phases that, in addition to the new building, include a renovation of the existing building stock and a consideration of the grounds and outdoor facilities, including the development of the sports field. The following changes are foreseen: • Extension of the Waldstraße Gymnasium by 10 classrooms and 2 chemistry rooms including adjoining rooms • Renovation of the extension building built in 1969 (energetic upgrade) if necessary with an increase • Replacement of the current sports hall with a 2-field hall, which can be divided into three sections • If necessary, replacement of the current entrance area with a new entrance hall / break hall. The city of Hattingen pays special attention to a sustainable building concept. It is of particular importance to use materials that correspond to an ecological footprint. However, a building certification is not fully sought, but only serves as a reference and should be in coordination with the client in the 2. Step to be worked out individually. However, the client is expected to include an initial concept for sustainable construction in the competitive result. The buildings to be realized should meet a high demand for a modern, energy-efficient building with optimal standards and become school buildings with exemplary function in their design, energy efficiency, functionality and cost-effectiveness. Due to the acute space requirements at the grammar school, a container system with 4 classrooms will be set up as a compensation measure until the completion of the new building. Completion of the container plant is planned for summer 2025. The location of the container plant is the parking lot adjoining the canteen to the west. If a new building is added to the existing building at this point, the handling of the interim building must be observed. In the event of an increase or extension of the stock through which measures are taken during operation, it is possible to extend the interim areas. In this case, a first rough concept for required interim areas or for the construction process in school operation should be attached to the competitive result. As a potential location for the interim building, the parking lot or sports field north of the sports hall is considered. The new construction of the entire project will take place during ongoing school operation. The entire construction site process should be carried out with the least possible impact on the operation.
