The traditional outdoor pool in Hamburg-Ohlsdorf was replaced after more than 40 years by a modern new building. The people of Ohlsdorf now use a sports and family pool area with a divisible 50-metre swimming pool, a training pool, whose bottom is adjustable in depth, and a paddling pool. Lindner´s responsibilities included carrying out plasterboarding works and installing wooden doors, the latter of which partially needing to comply with T30 fire protection requirements.
