Location & surroundings: renting an office in Ottensen
Ottensen is regarded as one of the liveliest and most popular trend-led quarters in the Hanseatic city, with short distances between the office, lunch and shopping. Just a few metres from the building lies Klopstockplatz with the restaurant JA AN, which offers a combination of sushi, Vietnamese and Asian cuisine in a quiet setting, along with an ice cream café for a short break. For a quick large shop or a lunch with a wider choice, the Mercado shopping centre with its numerous restaurants is around 250 metres away, in the middle of bustling Ottensen and only a stone's throw from Bahnhof Altona. Hamburg-Altona station is within walking distance and connects the space to the S-Bahn lines S1, S2 and S3 as well as to long-distance services.
Fit-out & building of the Alnwick-Harmstorf-Haus
The office building was constructed in 1974 and is undergoing extensive renovation until 2027, which affects both the quality of the space and its energy standard. Five outdoor parking spaces are available for employees travelling by car, although given the good public transport links, the bicycle or the train is likely to be the more obvious option for most of the workforce. Anyone opting for space in this building should factor the ongoing renovation period into their planning.
