egard to the old building, where the whole plinth was not accessible from street level. This is a major improvement for the liveliness. The main entrance is next to a new public square that will be formed with an all new the theatre. In the main staircase large mosaic whales accompany you on your ascend.
The main program consist of two swimming pools, a 50m1 sports pool and a 25m1 supporting pool. The large swimming pool is for competition and training purposes. The main focus is set specific on the sports activities and the athletes. All the materials used in this space are white, so the main view is on the sport activities and its participants. Champions and their competitors are clearly visible in contrast of their surroundings. The large seating area of 360 fixed chairs has entirely made blue. This has two main advantages; the color matches the imagery color of water and from the spectators point of view, the blue forms a dark frame in which all the sports activities take place.
For training purposes a special floating wall element which can submerge completely. This wall can divide the pool into three different sized areas so training exercises can be held simultaneously into separated areas. During large events, the number of seated spectators can increase to a thousand on specially prepared area’s on two sides of the platforms. The sports area is connected to a fitness and massage area which is located in the basement of the old building, so a wide number of services can be provided for the athletes.
The supporting pool is used for warming ups and/or cooling downs during competitions and is located directly next to the sports swimming pool. On the platform level there is a large visual connection between the two pools. The supporting pool also has an important role for the community, by providing a location for swimming lessons for young school children. For this purpose a free floating bottom floor with two different simultaneously height settings was added. The depth of the pool can be set from 2,2 to zero meters, so the pool is also accessible for people in wheelchairs or elderly. This pool will strongly provide a welcome addition to the local community. In contrast to the all-white sports pool, this supporting pool is more intimate and has a wellness/spa based ambiance and atmosphere.
The facades of the former health care building are made visible on some parts of the walls above the platforms. And, if one looks closely, the original facades can also be seen on the sports focused side, slightly masked behind all-white paint. Al lot has been done to maximize the acoustic quality within both of the swimming pool areas. Acoustic panels have been added in large quantities to control the overall acoustic dampening. Windows have been set to an angle to avoid scattering sound waves and a full seized suspend ceiling has been added in both swimming areas. The whole ceiling has been made accessible for maintenance and periodical inspections.
The community of Rotterdam owns a large number of sports related buildings, the department which oversees the activities held in all of these buildings is located in top sports Swimming Venue. This contributes to the idea of a sports related building complex. Some of the small shops located in the plinth are specialized in sports related products. To add more public facilities to the building a district center of the city of Rotterdam is located on the ground level. The location for this top sports venue is key for its success, it is next to public transportation, near to a well visited shopping area and widely within the city limits. The whole area will change into a more vibrant and lively neighborhood within the next five years due to several large new projects. The top sports venue is the first of several new developments in the area with their focus on sports, leisure and general improvements of the urban exterior quality.
All these combined functions will make this new building complex an important project in the south of Rotterdam. Already a large number of national and international sports competitions will be held in this top sports center within next few months, so records will be sharpened and new champions will rise in Rotterdam for the years to come.

Curriculum studio / partecipanteWe create environments that move people.
Environments where people work better, learn better, and enjoy themselves more. Such as public spaces, public buildings, and urban districts, where unique encounters occur, where beautiful memories are made, and where important decisions are taken.
We take our inspiration from socially relevant themes. And we look ahead as building is a slow process in a rapidly changing world.
For Kraaijvanger Architects transformation is one of the most important steps forward to a sustainable future for existing buildings. Our ideal is a building that supplies energy, purifies air and water, offers space to biodiversity and produces no waste. We try to achieve this by using as many healthy and reusable materials as we can and making all the cycles in the building as conclusive (water, materials, food, energy and air) as possible. Our ambition is clear with every project: 100% cradle to cradle and energy supplying.
