Providing a mix of office and retail space in almost equal measure, K2 Ellipse is an exception to the rule for buildings in Kirchberg and has thus been very well received. By contrast, K2 Forte is purely an office building and is able to retain tenants over the long term thanks to its high-quality design and fit-out and its flexible layout options. Both properties have BREEAM Excellent certification. Other buildings in the immediate area were also constructed by Belgian developer Codic and are likewise named after musical terms.

Kirchberg is one of the most sought-after office submarkets in Luxembourg. K2 Ellipse and K2 Forte are both part of an established office ensemble in which all the buildings are named after stylistic devices in music. They are primarily let to service companies in the legal and financial fields.
